Answer is A. 6
hope it helps
Answer:
A=6 and B=4.5
Step-by-step explanation:
You are given table
![\begin{array}{cccccc}x&2&4&[A]&7&9\\y&1&2&3&3.5&[B]\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcccccc%7Dx%262%264%26%5BA%5D%267%269%5C%5Cy%261%262%263%263.5%26%5BB%5D%5Cend%7Barray%7D)
If the paired values are in a proportional relationship, then
![\dfrac{2}{1}=\dfrac{4}{2}=\dfrac{[A]}{3}=\dfrac{7}{3.5}=\dfrac{9}{[B]}.](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B1%7D%3D%5Cdfrac%7B4%7D%7B2%7D%3D%5Cdfrac%7B%5BA%5D%7D%7B3%7D%3D%5Cdfrac%7B7%7D%7B3.5%7D%3D%5Cdfrac%7B9%7D%7B%5BB%5D%7D.)
Note that
then
![\dfrac{[A]}{3}=2\Rightarrow [A]=6,\\ \\\dfrac{9}{[B]}=2\Rightarrow [B]=\dfrac{9}{2}=4.5.](https://tex.z-dn.net/?f=%5Cdfrac%7B%5BA%5D%7D%7B3%7D%3D2%5CRightarrow%20%5BA%5D%3D6%2C%5C%5C%20%5C%5C%5Cdfrac%7B9%7D%7B%5BB%5D%7D%3D2%5CRightarrow%20%5BB%5D%3D%5Cdfrac%7B9%7D%7B2%7D%3D4.5.)
Answer:
B
Step-by-step explanation:
The slope is represented by x.
Since the slope of both equation is 1(the same), it means the lines will remain parallel.
m = 5a
m + a = 30
Because we already know the value of m, we can find the value of a.
5a + a = 30
<em><u>Combine like terms.</u></em>
6a = 30
<em><u>Divide both sides by 6</u></em>
a = 5
Now that we know the value of a, we can find the true value of m.
m = 5a
m = 5 * 5
m = 25
Aisha is 5 years old, and Aisha's mother is 25 years old. (This is your answer.)
