Answer:

[tex]\huge\boxed{x=9}[/tex]

Step-by-step explanation:

[tex]\angle A\cong\angle B\qquad\text{therefore}\qquad AC\cong BC\Rightarrow|AC|=|BC|\\\\\text{We have}\ |AC|=20;\ BC=3x-7.\\\\\text{Therefore}\\\\3x-7=20\qquad|\text{add 7 to both sides}\3x-7+7=20+7\\\\3x=27\qquad|\text{divide both sides by 3}\\\\\dfrac{3x}{3}=\dfrac{27}{3}\\\\x=9[/tex]

Answer:

3000 is your answer

Step-by-step explanation:

The 3 in the hundreds place if the number 587,349 has a value of 300. This 300 is 1/10 the value of the number you're looking for, so if x is the number you're looking for, then

[tex]300 = \frac{1}{10} x[/tex]

[tex]300 \times 10 = \frac{1}{10} x \times 10[/tex]

[tex]3000 = x[/tex]

x is your answer.

Answer:

x = (40/4)-7.50

x= (10)-7.50

x = 2.50

Step-by-step explanation:

each boy had 2.50 left after the movie because miguel went with 3 other boys, which makes four of them all together. If they had forty dollars all together and all had the same amount of money, you can determine that amount by dividing forty(total money) by 4(number of boys). Which gets you to the answer of ten dollars each. Then you subtract the ticket cost(7.50) from 10 dollars, which gets you to 2.50 left over.

A scatter plot matrix shows all pairwise scatter plots for many variables. If the variables tend to increase and decrease together, the association is positive. If one variable tends to increase as the other decreases, the association is negative, I hope this helps

Answer:

r = 2

r = -1

Step-by-step explanation:

So first, we need to get this is order of: ax^2 + bx + c

3r^2 - 6 - 3r

3^2 - 3r - 6

the formula is: -b ± √b^2 -4ac/2a

"ax^2 + bx + c" = "3^2 - 3r - 6"

a = 3

b = -3

c = -6

-b ± √b^2 -4ac/2a

-(-3) ± √(-3)^2 -4(3)(-6)/2(3)

3 ± √9 + (-12)(-6)/6

3 ± √9 + (72)/6

3 ± √9 + 72/6

3 ± √81/6

3 ± 9/6

3 - 9/6

-6/6

-1 = r

3 + 9/6

12/6

2 = r

ha you said C O C K

Step-by-step explanation:

Answer:

the answer is B I think sorry if I'm wrong

We want to check if function A has a greater initial value than function B. We will see that Emma is incorrect, the correct option is the third one.

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept (we can also call the y-intercept as the initial value).

For function A we can see that the initial value is y = -2

While for function B we need to find it, but by looking at the table, we can see that for each increase of 2 units in the x-variable we have an increase of one unit on the y-variable.

Then we can see that for x = 0, we would have y = 1.

Meaning that the initial value of function B is y = 1, which is greater than the one for function A.

Then Emma is incorrect, the correct option is the third one.

7−(2−5(4−7)+6)+7

=7−(2−(5)(−3)+6)+7

=7−(2−(−15)+6)+7

=7−(17+6)+7

=7−23+7

=−16+7

=−9

Thus, the answer is -9

In any rhombus, the four sides are the same length.

Because of this, we know that

Furthermore, AC = AC due to the reflective property

Those three facts then allow us to prove triangle ACD is congruent to triangle ACB through the SSS congruence property. Then from CPCTC, we then know that  angle DAC = angle BAC,  which is enough to show that AC bisects the angle shown. The term "bisect" means "cut in half".

Answer: 45

Length is how long something is  and the triangle shows 45 as the length

[tex]\frac{3}{12} =\frac{x}{28} \\28(\frac{3}{12} )=x\\x=7[/tex]

Answer:

7

Step-by-step explanation:

we first divide 12 by 3 and we get

[tex]\frac{12}{3}=\frac{4}{1}[/tex]

that means:

for 4 pints we have 1 pitchers

so 28=4*7

[tex]\frac{4}{1}*\frac{7}{7}=\frac{28}{7}[/tex]

so that means for 28 pints we have 7 pitchers

Answer:

1) 90+30+x=180

x= 60

2) 2x+90=180

x= 45

3) angle SPQ

90+55+ SPQ=180

SPQ= 35

Therefore as op=os=radii= isosceles triangle

angles OPS=OSP

SPQ +QPO=OSP

35 + x = 55

x=20

4)110+ 90+90 +x=360

x=70

5)90 +90 +45+x=360

x=135
