4x=20
4/4x=20/4
x=5
u want to isolate the variable to solve these equations
Answer:
x = - 191/28
Step-by-step explanation:
14 (8x + 56) = 20
112x + 784 = 20
112x = 20 - 784
112x = - 764
x = - 764/112
x = - 191/28
Answer:32m
Step-by-step explanation:
So you would have to divide 160 and 5 and it would equal 32

Take 12 x 7 then do the answer over 1 to get the total
Answer:
Height of the slide from the ground = 1.80 m
Step-by-step explanation:
In this question the given values are length of the slide is 3.1 m and the angle of slide with the ground = 35°
Now if we imagine the triangle formed by slide and ground will be a right angle triangle so we can apply sin rule to get the height of the slide from the ground.
Now we know sin ∅ = height / hypotenuse
Here ∅ = 35° and hypotenuse = 3.1
Therefore sin∅ = 
Or height x = 3.1 sin 35°
x = (3.1) × (.57) = 1.77 ≈ 1.80 m
The height of the slide from the ground is 1.80 m.
