Answer:
t = 1
Step-by-step explanation:
16 - 2t = t + 9 + 4t
=> 16 - 9 = 7t
=> 7 = 7t
=> t = 1
First, we know that y is equal to -8x, so we can move the -8x to replace y in the first equation, then in the first equation we get -8x=6x-14, subtract 6x on both sides, -14x=-14, x=1

Answer:
To find the scale factor, all you have to do is <em>divide a side value of one figure by its congruent side value on another figure. </em>
Step-by-step explanation:
To start:
- The values 15 and 10 are both for the same congreunt side --> EF and E'F'
- The values 4 and 6 are both for the same congreunt side --> DE and D'E'
- The values 4 and 6 are both for the same congreunt side --> DG and D'G'
- The values 8 and 12 are both for the same congreunt side --> FG and F'G'
So, to find the scale factor, all you have to do is divide the smaller congruent value from the larger congruent value.
Larger congruent value ÷ smaller congruent value = scale factor
15 ÷ 10 = scale factor
\____________________/
1.5
<h3>So, the scale factor is 1.5</h3>
To double check, we will use another congruent side to find the scale factor:
12 ÷ 8 = scale factor
1.5 = scale factor
<h3>So, the scale factor is most definitely 1.5</h3>
I hope this helps!
