For value of v, determine whether it is a solution to 21=5v+1. Is -7 a solution

Alisiya [41]

Hello.

Given the equation:

$\mathsf{\boxed{5v + 1 = 21}}$

Testing for v = -7

$\mathsf{5v + 1 = 21} \\ \\ \mathsf{5 \times (-7) + 1 = 21} \\ \\ \mathsf{-35 +1 = 21} \\ \\ \mathsf{-34 = 21}$

-34 does not equal 21. Therefore, '-7' is not a solution.

Hope I helped.

2)TNY

3) QWE(maybe F, cant read it perfectly)

4) VOR

5) AYD

6) GNH

7) MSE

8) TCA

9) ATE

Step-by-step explanation:

you need to look at the hashes, each segment that had one hash, is equivalent to the other segments with one hash, and so on. then you have to look and see which segments match on each shape. so let's say that if H is the same as A, and I is the same as B, and J is the same as C, then in ∆ HIJ, it would be equivalent to ∆ABC
