Answer:
Step-by-step explanation:
Given the equation:
1/5 × (x - 2) = 20
First step to solving the equation is
By multiplying both sides by the value of 5.
That will give,
x - 2 = 100
x = 100 + 2
= 102
Answer:
84
Step-by-step explanation:
because the top and bottom lines are parallel, we can conclude that the 2 triangles (top and bottom) are similar triangles. This means the sides lengths of smaller triangle is proportional to the respective sides on the larger triangle. With this, we can form the following equation:
x/48 = 21/12 (multiply both sides by 48)
x = (21/12)· 48
x = 21 ·4
x = 84
I maybe wrong but think it's 7 kids or 8 kids but I'm not to sure
Answer:
The length of the slide he needs to make = AC = L = 14.3 ft
Step-by-step explanation:
From the Δ ABC
AC = Length of the slide = L
AB = 9 ft
°
From Δ ABC
Put all the value in the above formula
L = AC = 14.3 ft
Therefore the length of the slide he needs to make = AC = L = 14.3 ft
Answer:
We see that the big triangle is an equilateral triangle, so all its angles will measure 60°. Therefore x° will be 60° - 30° = 30°, as he's the base angle of an isosceles triangle having the other base angle of 30°. y will simply be 180° - 60° (remembering that the sum of the angles in a triangle is always 180°).
