Can someone help in math 1. Simplify the expression 8 squared plus 9 left parenthesis 12 divided by 3 times 2 right parenthesis minus 7. Explain each of your steps.

2. Using the numbers and symbols, solve

7x = 42

3 times y divided by 8

(the last answer)

Because "3y" comes first and then "÷ 8" so the order is correct with 3 times y divided by 8, and the others can be ruled out.

Answer:

None

Step-by-step explanation:

All angles must add up to 180 in a triangle. 60+60+40=160. therefore, no triangles can be made with these angles.

Answer:

103 and 68

Step-by-step explanation:

Given

A + B = 171

A - B = 35

Add the two expressions to eliminate B.

B + (-B) = B - B = 0

We have

2A = 206

Divide both sides by 2 to isolate A

2A/2 = 206/2

A = 103

Now substitute 103 for A in either expression to get B

Using the first expression , we have

A + B = 171

103 + B = 171

Subtract 103 from both sides

103 - 103 + B = 171 - 103

B = 68

The numbers are 103 and 68

Check

103 + 68 = 171

103 - 68 = 35

Answer:

103 and 68

Step-by-step explanation:

since the difference has to be 35 subtract 35 from 171 (equals 136) then divide it by 2, you get 68 which is your first number, then add 35 back and get 103 for the second number, I hope this helped

Answer:

y = x - 5

Step-by-step explanation:

In point slope form (y=a(x-h)+k):

y = 1(x - 5) + 0

simplifies to:

y = x - 5
