V=vanila
c=chocolate

4v+1c=45
v+c=27

mulitply 2nd equation by -1 and add to top one

-v-c=-27
<u>4v+1c=45 +</u>
<u />3v+0c=18

3v=18
divide by 3
v=6

sub back
v+c=27
6+c=27
c=21

21 choc and 6 van

A.
v+c=27
4v+1c=45
v=number of vanila wafers bought
c=number of chocolate wafers bought

B. 21 chocolate and 7
I got the answer with math because math is fun and tada

triangle RSt is similar to triangle xyz with rs= 3 inches and xy= 2 inches. Of the area of triangle RST is 27 in^2, determine an

Luden [163]

Answer: The area of triangle ΔXYZ is 12 square inches.

Step-by-step explanation:

Since we have given that

RS = 3 inches

XY = 2 inches

Area of ΔRST = 27 in²

Since ΔRST is similar to ΔXYZ.

So, using the "Area similarity theorem":

$\dfrac{\Delta RST}{\Delta XYZ}=\dfrac{RS^2}{XY^2}\\\\\dfrac{27}{\Delta XYZ}=\dfrac{3^2}{2^2}\\\\\dfrac{27}{\Delta XYZ}=\dfrac{9}{4}\\\\\Delta XYZ=3\times 4=12\ in^2$

Hence, the area of triangle ΔXYZ is 12 square inches.
