Answer:
1. -3 2. 3
Step-by-step explanation:
Evaluate each expression is very simple concept in math. When you substitute a particular value for each variable and then act the operations called evaluating expression.
Answer:
2. n = 11
4. g = -2
6. t = 21
8. n = 4
10. y = -1
Step-by-step explanation:
2. 63 = -3(1 - 2n)
Dividing both the side by negative 3 we get

4. -g + 2(3 + g) = -4(g + 1)
First we will open the bracket by distributive property A( B +C) = AB + AC

6.-3(t +5 ) + (4t + 2) = 8
Using distributive property A( B +C) = AB + AC we get

8. -8 - n = -3(2n -4)
Using distributive property A( B +C) = AB + AC we get

10. -4( 2 - y) + 3y = 3(y - 4)
Using distributive property A( B +C) = AB + AC we get

Answer:
Step-by-step explanation:
ok so this is a vetical angle. so they are equal to 180. so if 1 measurement is found the other is the difference of 180 and that angle measeurement.
so y is the same as 110
and 180 - 110 is 70, so x and z are equal to 70.
i hope this helped you :)
Answer:
each triangle should weigh 2.5!
Step-by-step explanation:
each sides are equal. the side with only squares weighs 25. the squares on the opposite side weigh 10. 25-10 is equal to 15. there are 6 triangles. 15 divided by six gets you 2.5
