Let x ft be the length of the ladder, then the distance from the ground to the top of it will be x-1 ft.
If the distance from the bottom of the ladder to the building is 3 ft, then we can apply Pythagoras:
x² = (x-1)² + 3² . Expand:
x² = x² - 2x + 1 + 9
x² = x² - 2x + 10
x² - x² = - 2x + 10
0 = - 2x + 10
2x = 10 and x = 5 ft
Answer:
i cant really see
Step-by-step explanation:
Distribute the 2 then do your loop.
5^3 = 2x+16
Then you can solve for x.
Answer:
Discounted price = $495 Discount Rate = 34% Solution: Let x = Original Price x = 495 + 0.35x ;Multiply whole equation by 100 to remove decimals. 100x = 49500 + 35x ;Transpose 35x to the left side of the equation. 100x-35x = 49500 ; Subtract the x terms. 65x = 49500 ; Divide both sides by 65. x = 761.54 So the original price is $761.54.
M/k=x
(m)m/k=x(m)
k=xm
Because you are diving one the side where m/k, you need to multiply m to both sides to get rid of it on one. Therefore, you are left with K=XM
