Answer:
About 163 (Exact Answer: 163.1)
<h2>
Step-by-step explanation:</h2>
11.3s + 10.5t
Replace s with 7 and t with 8.
11.3(7) + 10.5(8)
Multiply.
11.3(7) + 10.5(8) =
79.1 + 84
Add.
79.1 + 84=
163.1 ≈ 163
(This is a little difficult but I've got it)
((x - 45)/12) + 20 = 5(32 - x)
(I made the equation a little more complex than I should have but that equation should still work if you were to solve for x)
Remember, you can do anything to an equationas long as you do it to both sides
1.
-6+x=-3
add 6 to both sides
6-6+x=6-3
0+x=3
x=3
2.
add like terms
-5a+5a+9=8
0a+9=8
0+9=8
9=8
false
no solution
zero solutions
Dilation since then the lengths are changed. The image would then be only similar; not congruent.
