Answer:
x = 9; y = 12; u = 24; v = 32
Step-by-step explanation:
The corresponding sides of similar triangles are in the same ratio to each other.
3/5 = (3 + x)/20 Multiply each side by 20
20×3/5 = 3 + x
12 = 3 + x Subtract 3 from each side
x = 9
=====
4/5 = (4 + y)/20 Multiply each side by 20
20×4/5 = 4 + y
16 = 4 + y Subtract 4 from each side
y = 12
=====
3/5 = (3 + x + u)/60 Multiply each side by 60
60×3/5 = 3 + x + u
36 = 3 + x + u Insert the value of x
36 = 3 + 9 + u
36 = 12 + u Subtract 12 from each side
u = 24
=====
4/5 = (4 + y + v)/60 Multiply each side by 60
60×4/5 = 4 + y + v
48 = 4 + y + v Insert the value of y
48 = 4 + 12 + v
48 = 16 + v Subtract 16 from each side
v = 32
x = 9; y = 12; u = 24; v = 32
Answer:
A,B,D,E,H
Step-by-step explanation:
First, write an expression.
The correct expression is n + 8.
Second, substitute 5.3 for the variable, n.
Third, simplify by adding 5.3 and 8.
The answer is 13.3.
Answer:
One block - 15
Two blocks - 30
Three blocks - 45
Four blocks - 60
Five blocks - 75
Equation: 25 + 5x = 100
Step-by-step explanation:
This is a pretty simple problem. The scale is balanced and from what we know, the 100 and 25 are on different sides. If we want the scale to be balanced, then we have to solve the equation:
25 + 5x = 100.
(We have the 5x because we have 5 blocks that are marked as x)
subtract 25 from both sides
25-25 + 5x = 100-25
5x = 75
the following step is to divide both sides by 5.
5x/5 = 75/5
x = 15
Now that the equation is solved, we know that ONE blocked marked as X equals 15-g.
(All five of them equal 75-g)
