Answer:
see explanation
Step-by-step explanation:
Given
3(x - 6) = - 15 + 3x ← distribute parenthesis on left side
3x - 18 = - 15 + 3x ( add 18 to both sides )
3x = 3 + 3x ( subtract 3x from both sides )
0 = 3 ← not possible
This indicates the equation has no solution
True or false: if two parallel lines are cut by a transversal, each pair of alternate angles are congruent?
Answer: True.
If two parallel lines are cut by a transversal, then the alternate interior angles formed are congruent . When two lines are cut by a transversal, the pairs of angles on either side of the transversal and outside the two lines are called the alternate exterior angles .

Answer:
She will hire EZ Excavation.
Step-by-step explanation:
For a company EZ Excavation,
Per cubic yards cost of the dirt = [tex]\frac{\text{Total cost}}{\text{Volume of the dirt}}[/tex]
= [tex]\frac{196}{8}[/tex]
= $24.5
Total cost of 40 cubic yards of the dirt = 40 × 24.5
= $980
For second company Happy Hauling service,
Per cubic yard cost of the dirt = [tex]\frac{25}{1}[/tex]
= $25
Cost of 40 cubic yards of the dirt = 40 × 25
= $1000
Budget of the contractor = $1000
Cost of dirt offered by EZ Excavation is in her budget and she is saving $20.
Therefore, she will hire EZ Excavation.

Answer:
1. The square root of 100
2.c=27.11
d=13.96
e=12.6
Step by step explanation:
1. 2×50=100 the geometric mean is the square root of 100
2. The diagram is made up of three right angled triangles the big outer one and two triangles inside the big one thus we can use the pythagorean theorem to come up with expressions which will help us in solving the unknown parts as below.
c²=30²-d²
c²=e²+24²
d²=e²+6²
both the following add up to c² meaning they are equal:
c²=30²-d²
c²=e²+24²
thus
30²-d²=e²+24²
I want to remain with d² only thus;
30²-24²-e²=d²
900-576=324 (squareroot of 324=18) so
d²=18²-e² and d²=e²+6²
both the above add up to d² meaning they are equal thus;
18²-e²=e²+6²
18²-6²=e²+e²
324-36=2e²
318=2e²
159=e²
e=12.61
Thus d²=e²+6²
d²=12.61²+6²
d²=159+36
d²=195
d=13.96
c²=e²+24²
c²=12.61²+24²
c²=159+576
c²=735
c=27.11

The measure of Angle d is 150°. What is the value of Measure of angle b + measure of angle c + measure of angle e?
Answer:
[tex]\angle b + \angle c + \angle e = 120^\circ[/tex]
Step-by-step explanation:
Given
[tex]\angle d = 150[/tex]
See attachment for illustration
Required
Find [tex]\angle b + \angle c + \angle e =[/tex]
The sum [tex]of\ angles\ at[/tex] a point is [tex]360^\circ[/tex]
So:
[tex]\angle a + \angle b + \angle c + \angle d + \angle e = 360^\circ[/tex]
Angle a is at right angled.
So:
[tex]90 + \angle b + \angle c + 150 + \angle e = 360^\circ[/tex]
Collect like terms
[tex]\angle b + \angle c + \angle e = 360^\circ -150^\circ - 90^\circ[/tex]
[tex]\angle b + \angle c + \angle e = 120^\circ[/tex]

The Area of EFGH is 2x+9 which is similar to The Area of JKLM is 2x-6. The perimeter of EFGH is x+3 which is similar to the Perimeter of JKLM is x-1. FInd all Possible values of X.
Answer:
[tex]x = 9[/tex]
Step-by-step explanation:
Assume EFGH and JKLM are rectangles
JKLM appears to be the smaller of both.
So:
[tex]EF = n * JK[/tex] and [tex]GH = n * LM[/tex]
Where n is the scale of dilation
The area of EFGH is:
[tex]Area = EF * GH[/tex] ----- (1)
Substitute [tex]EF = n * JK[/tex] and [tex]GH = n * LM[/tex]
[tex]Area = n*JK * n*LM[/tex]
[tex]Area = n^2*JK * LM[/tex]
So, we have:
[tex]Area = EF * GH[/tex] and [tex]Area = n^2*JK * LM[/tex]
[tex]EF * GH = 2x + 9[/tex] --- Given
[tex]JK * LM = 2x - 6[/tex] --- Given
So:
[tex]Area = EF * GH[/tex] and [tex]Area = n^2*JK * LM[/tex]
[tex]Area = 2x + 9[/tex] and [tex]Area = n^2 * (2x - 6)[/tex]
Equate bot areas
[tex]2x + 9 = n^2*(2x - 6)[/tex]
Make n^2 the subject
[tex]n^2 = \frac{2x + 9}{2x - 6}[/tex]
The perimeter (P) of EFGH is:
[tex]P = 2*(EF + GH)[/tex] ----- (1)
Substitute [tex]EF = n * JK[/tex] and [tex]GH = n * LM[/tex]
[tex]P = 2*(n*JK + n*LM)[/tex]
[tex]P = 2n*(JK + LM)[/tex]
So, we have:
[tex]P = 2*(EF + GH)[/tex] and [tex]P = 2n*(JK + LM)[/tex]
[tex]2*(EF + GH) = x + 3[/tex] --- Given
[tex]2*(JK + LM) = x - 1[/tex] --- Given
So:
[tex]P = 2*(EF + GH)[/tex] and [tex]P = 2n*(JK + LM)[/tex]
[tex]P =x + 3[/tex] and [tex]P = n *(x - 1)[/tex]
Equate bot perimeters
[tex]x + 3 = n(x - 1)[/tex]
Make n the subject
[tex]n =\frac{x + 3}{x - 1}[/tex]
Square both sides
[tex]n^2 =\frac{(x + 3)^2}{(x - 1)^2}[/tex]
Recall that: [tex]n^2 = \frac{2x + 9}{2x - 6}[/tex]
So, we have:
[tex]\frac{(x + 3)^2}{(x - 1)^2} = \frac{2x + 9}{2x - 6}[/tex]
Evaluate all squares
[tex]\frac{x^2 + 6x +9}{x^2 - 2x + 1} = \frac{2x + 9}{2x - 6}[/tex]
Cross multiply
[tex](x^2 + 6x +9)(2x - 6) = (x^2 - 2x + 1)(2x + 9)[/tex]
Open brackets
[tex]2x^3 +12x^2 + 18x - 6x^2 -36x -54 = 2x^3 - 4x^2 + 2x + 9x^2 - 18x +9[/tex]
Subtract 2x^3 from both sides
[tex]12x^2 + 18x - 6x^2 -36x -54 = - 4x^2 + 2x + 9x^2 - 18x +9[/tex]
Collect like terms
[tex]12x^2 - 6x^2 + 18x -36x -54 = - 4x^2 + 9x^2+ 2x - 18x +9[/tex]
[tex]6x^2 - 18x -54 = 5x^2- 16x +9[/tex]
Collect like terms
[tex]6x^2 -5x^2 - 18x +16x -54 -9= 0[/tex]
[tex]x^2 -2x -63= 0[/tex]
Expand
[tex]x^2 +7x - 9x - 63 = 0[/tex]
Factorize
[tex]x(x +7) - 9(x + 7) = 0[/tex]
[tex](x -9) (x + 7) = 0[/tex]
[tex]x = 9\ or\ -7[/tex]
x can not be negative.
So: [tex]x = 9[/tex]
A bag contains:
• 2 white marbles
3 brown marbles
4 purple marbles
• 6 orange marbles
A marble will be drawn from the bag and replaced 75 times. What is a reasonable prediction for the number of times a brown or purple marble
will be drawn?
50
45
35
30
th
Answer:
45
Step-by-step explanation:
There are 45 total marbles. The probability of drawing a yellow marble on the first draw is 3/4. Given replacement, the probability on the second draw is the same as on the first draw, so the probability of black marble on the second draw is 6/14. The probability of drawing first a yellow marble then a black marble is 3/14 * 6/14 = 18/196.

Carrie found the difference 11/12 -- 2/3. she said * i found a common denominator 12,then subtracted the numerators to get 9/12* is carrie correct? Explain why she is or not correct.
Answer:
She isn't correct because after you find the common denominator, the numerator needs to be changed as well, so when she multiplied the denominator of 2/3 by 4 to get 12, she also had to multiply the 2 by 4, to get 8/12, and then subtracted, because otherwise, the new fraction isn't equivalent to the original fraction.

A ladder is 51 inches tall. How tall is it in feet and inches?
Answer:
4 feet and 3 inches
Step-by-step explanation:
The measure of ladder in feet is 4.15.
Given that, a ladder is 51 inches tall.
Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.
We know that, 1 feet = 12 inches
So, in inches = 51/12
= 4.25 feet
Therefore, the measure of ladder in feet is 4.15.

Find the area of △LKJ.
Answer:
[tex]A=600\: u^{2}[/tex]
The correct answer is letter c.
Step-by-step explanation:
The area equation of a triangle is given by:
[tex]A=\frac{bh}{2}[/tex] (1)
Where:
b is the base
h is the height
Let's find first the angle MJK (α), using the tangent definition.
[tex]tan(\alpha)=\frac{24}{32}[/tex]
[tex]\alpha=tan^{-1}(\frac{24}{32})[/tex]
[tex]\alpha=36.9^{\circ}[/tex]
Now, if α = 37° then β (angle JLK) must be:
[tex]37^{\circ} + \beta + 90^{\circ}=180^{\circ}[/tex]
[tex]\beta=53^{\circ}[/tex]
Now, we can find the distance ML using again the tangent definition:
[tex]tan(\beta)=\frac{24}{ML}[/tex]
[tex]ML=\frac{24}{tan(53)}[/tex]
[tex]ML=18[/tex]
The base of the triangle LKJ will be:
[tex]b=32+ML=32+18=50[/tex]
Therefore, using equation (1) the area of △LKJ will be:
[tex]A=\frac{50*24}{2}[/tex]
[tex]A=600\: u^{2}[/tex]
The correct answer is c.

Two people share £250 in the ratio 2 : 3 calculate each share
Step-by-step explanation:
Let the shared amount be 2x and 3x Then
2x + 3x = £ 250
5x = £ 250
x =£250/ 5
x = £ 50
Now
2x = 2 *£ 50 = £ 100
3x = 3 * £50 = £150
