It’ll be -5x - 24
you multiply the 5 by 4 and it’ll be 24, and put the x with the 5 and that’ll be your answer :)
X = -2
Combine terms to get:
-18x - 5 = 31
Add 5 to both sides
-18x = 36
Divide by -18
x = -2
Answer:
r < 4
Step-by-step explanation:
r+6<10
r < 4
Answer:
E - 40°
Step-by-step explanation:
Angle O = 2 × y
{Angle at center is equal to twice the angle at circumference formed by the same arc}
O = 2 × 70°
O = 140°
x + 90° + 90° + O = 360°
{Sum of angles in a quadrilateral is equal to 360°}
x + 90° + 90° + 140° = 360°
x + 320° = 360°
x = 40°
Answer:
a = 20
Step-by-step explanation:
The mean is calculated as
mean = 
= 
= 
Then
= 27 ( multiply both sides by 5 to clear the fraction )
115 + a = 135 ( subtract 115 from both sides )
a = 20
