Five more than four times a number
Answer: 4x +5
Step-by-step explanation:
I really need help with this one
Answer:
28
Step-by-step explanation:
Since B is the midpoint of AC, that means AB = BC. That means 3x+4 = 5x-6. We can now set up an equation to solve for x:
3x+4 = 5x-6
3x+10 = 5x
10 = 2x
x = 5
Now that we know what x is, we can just plug x into the expression of AB and multiply it by 2:
(3*(5)+4)*2
=(15+4)*2
=19*2
=28
(side note: we could have plugged x into the expression of BC as well, but in this case plugging it into AB tends to be easier to solve)
Therefore, the length of AC is 28.

Answer:
The final answer in the most simplest form is 3/32
Step-by-step explanation:
3/8(3/4+5/6)-1/2
3/8( 38/24)-1/2
114/192-1/2=36/184
Divide by 12 for the 36 and 184
the final answer should be 3/32

What is Three-fourths divided by one-sixth? A fraction bar labeled 1. Under the 1 are 4 boxes containing one-fourth. Under the 4 boxes are 6 boxes containing one-sixth. Under the 6 boxes are 12 boxes containing StartFraction 1 Over 12 EndFraction. 3 4 4 and StartFraction 1 Over 12 EndFraction 4 and one-half
Answer:
4 and one-half
Step-by-step explanation:
Given the expression (3/4)÷(1/6), we are to simplify it. See the workings below;
(3/4)÷(1/6)
= 3/4 × 6/1
= (3×6)/4
= 18/4
= 9/2
Write as a mixed fraction
= 4 1/2
Hence the correct answer is 4 and one-half

Solve for x.
Зxy = W
Answer:
[tex]\huge\boxed{x=\frac{W}{3y}}[/tex]
Step-by-step explanation:
If we have the equation [tex]3xy=W[/tex] and we want to solve for x, our goal is to isolate x one one side of the equation.
The question we have to ask ourself is ”What’s stopping x from being isolated?”
That would be the 3 and the y.
Since we’re multiplying x by the 3 and the y, we can divide both sides by the 3 and the y to get x isolated.
[tex]3xy \div 3y = w \div 3y[/tex]
[tex]x = \frac{W}{3y}[/tex]
Hope this helped!

Which equation fits the situation? Mikes test score was 20 points lower than marks if mark scored a 95 on the test which equation would give mike’s score
Answer:
95 - 20 = t
Step-by-step explanation:
Let's start with the facts. You know that Mike's test score is 20 points lower than Mark's. You know that Mark's score was 95.
If we are trying to find Mike's test score, t, the equation would be this:
The equation would be 95 - 20 = t

A car can travel 80 miles on 4 gallons of gasoline. If the gas tank, which can hold about 15 gallons, is half full, how many miles can the car travel before it runs out gas?
Answer: 150
Step-by-step explanation: A car can travel 80 miles on 4 gallons of gas if the gas tank can hold about 15 gallons is half full there will be 7.5 gallons of gas in the can so multipy the 80 miles by 1.875, 150
a sno-cone machine priced at 139$ is on sale for 20% off , the sale tax is 10
Answer:
The overall price would be 125.1
Step-by-step explanation:
The sales tax is $13.90
the sale takes off $27.8
So 139 - 27.8 + 13.9 is 125.1

If b= 40 degrees and c= 30 degrees, what is the measure of d?
Answer:
It would be D. 110 degrees
Step-by-step explanation:
A triangle is always equal to 180 degrees. So, if you add b + c, you get 70 degrees. Subtract that from 180, and you get 110. Hope this helped!
Answer:
a = 110 degree
d= 70 degree
Step-by-step explanation:
a+b+c = 180. (being sum of all interior angle of a triangle is 180 degree)
a+40+30 = 180
a=180-70
a = 110
Similarly,
a+d=180. (being supplementary angle)
110+d=180
d= 70
Rewrite the expression in the form 3^n.
Explanation:
Cross off four copies of '3' in both the numerator and denominator. Each pair cancels because 3/3 = 1, and 1 times any number is the same number. See the diagram below.
The numerator will be left with two copies of '3'. The denominator won't have anything left.
So we have 3*3 = 3^2

which number is bigger than the other? -0.75 or -5/4!! Please help!
Answer:
-0.75

-0.75 is bigger because it has a greater value.... it is closer to zero, on a number line.
given: y is the midpoint of XZ
prove: XY 1/2XZ
Given:
Y is the midpoint of XZ.
To prove:
[tex]XY=\dfrac{1}{2}XZ[/tex]
Proof:
It is given that Y is the midpoint of XZ. It means Y divides the line segment XZ in two equal parts XY and YZ.
[tex]XY=YZ[/tex] ...(i)
Point Y lines on the segment XZ, so by segment addition theorem, we get
[tex]XY+YZ=XZ[/tex]
[tex]XY+XY=XZ[/tex] [tex][Using (i)][/tex]
[tex]2XY=XZ[/tex]
Divide both sides by 2.
[tex]XY=\dfrac{1}{2}XZ[/tex]
Hence proved.

Answer:
[1/7 x - 1/5][(1/49 x²)+(1/35 x)+(1/25)]
(0.1b - 2)[0.01b²+0.2b+4]
Step-by-step explanation:
a³-b³=(a-b)(a²+ab+b²)
So
1/343 x³ - 1/125
[(1/7)x]³ - [1/5]³
[1/7 x - 1/5][(1/7 x)²+(1/7 x)(1/5)+(1/5)²]
[1/7 x - 1/5][(1/49 x²)+(1/35 x)+(1/25)]
And
0.001b3 - 8
(0.1b)³-(2)³
(0.1b - 2)[(0.1b)²+(0.1b)(2)+2²]
(0.1b - 2)[0.01b²+0.2b+4]
How do you know whether two quantities x and y are proportional? Every ratio yx for related pairs of x and y is equivalent. Every sum x + y is the same for related pairs of x and y. Every x term is a multiple of the previous term. Every difference x – y is the same for related pairs of x and
Answer:
Two quantities x and y are said to be proportional if ratio yx for related pairs of x and y is equivalent.
Step-by-step explanation:
Two quantities x and y are said to be proportional if ratio [tex]yx[/tex] for related pairs of [tex]x[/tex] and y is equivalent.
The symbol ∝ is used to denote the proportionality. For example, if [tex]x[/tex] is proportional to y, then it is represented as [tex]x[/tex]∝y and if [tex]x[/tex] is inversely proportional to y, then it is represented as [tex]x[/tex] ∝ 1/y
