Answer:

7) Obtuse, I didn't use a protractor, so I'm estimating about 130 degrees.

8) Straight, all straight lines are equal to 180 degrees.

9) Acute, I estimated about 30-40 degrees, again, no protractor used.

How do you solve 2m-10=44+8m

Damm [24]

Answer:

m = -9

Step-by-step explanation:

2m-10=44+8m

Subtract 2m from each side

2m-2m-10=44+8m-2m

-10 = 44+6m

Subtract 44 from each side

-10-44 = 44-44+6m

-54 = 6m

Divide by 6

-54/6 = 6m/6

-9 = m

What is hs the answer to this question? Y= 5x+5 Y - x=5

ANEK [815]

Y = 5x + 5
y - x = 5

You can use substitution to solve this system. Use y's expression (5x + 5) for y in the second equation to solve for x:

y - x = 5
5x + 5 + x = 5
6x + 5 = 5
6x = 0
x = 0

Substitute your value for x into one of the original equations to y:

y = 5x + 5
y = 5(0) + 5
y = 5

Finally, substitute both values into both original equations to check your work:

5 = 5(0) + 5 --> 5 = 5 <--True
5 - 0 = 5 --> 5 = 5 <--True

Answer:
x = 0
y = 5
