Answer:
(-10,-6)
Step-by-step explanation:
(8 + b) / 2 = - 1
(8 + b) = - 1 * 2
8 + b = - 2
b+8-8 = -2 - 8
b = - 10
=====================
(a + 4)/2 = -1
(a + 4) = - 2
a + 4 = -2
a + 4-4 = - 2 - 4
a = - 6
Answer:
D
Step-by-step explanation:
3/7 + 6/7 = 9/7
Change 9/7 to a mixed number = 1 2/7
Add your whole numbers: 1 + 10 + 1 = 12
Answer: 12 2/7
Answer:
$260
Step-by-step explanation:
20% is equal to decimal form 0.2 or fraction form 1/5
1/5 of 800 = 1/5 * 800 = 160
He earns 100$ everyday even if he made sales worth $0.
100 + 160 = 260
When you don’t know the degree of a shape just use this form
180(n-2). Where n is the number sides of the shape.
There are 4 sides
180(4-2) = 180(2) = 360
So this shape is 360 degrees
120 + 120 + 60 +x = 360
300 + x = 360
X= 60
But as you can see that you don’t need this form for this question the alternate interior show you that the missing angles is 60
A)5x = 122+3
5x = 125
x = 125/5
x = 25
B) 3x = 81-3
3x = 78
x = 78/3
x = 26
