12/15 = 8/x
Cross multiply:
12*x = 8*15
⇒ 12*x= 120
⇒ (12/12)*x = 120/12
⇒ x= 10.
Final answer: x=10.
Hope this helps~
Answer:
x=-4
Step-by-step explanation:
The two lines are parallel, so the two angles, 45 and x+49 are equal too
Lets make the equation
x+49 = 45
x = 45-49
x = -4

Answer:
1/2 pi
Step by step explanation:
Find the circumference
2πr = 2xπx2 = 4π
Find the angle of JHI
Since 1/2π is 1/8 of 4π,
Angle JHI should also be 1/8 of 360 = 45 degrees
To find area, 45/360 x π X 2^2
= 1/8 x 4π
= 1/2 π
F(5)=x*10=50
um..
5x+5x+(2x+4)+(2x+4)=50
The answer is B
As the question states that you need to "subtract 4 from 12" that means that you are taking 4 away from 12, so it would be 12-4.
Then it says to divide by 8. This means that for the subtraction to happen first, it must be withing parenthesis, so that would make the expression become
(12-4)÷8
