Answer:
x=28
Step-by-step explanation:
We can use similar triangles and proportions to solve this problem. Put the side of the small triangle over the same side of the larger triangle.
x 42
---------- = ----------
x+10 42+15
Simplify
x 42
---------- = ----------
x+10 57
Using cross products
57x = 42 (x+10)
Distribute
57x = 42x+420
Subtract 42x from each side
57x-42x = 42x-42x +420
15x = 420
Divide each side by 15
15x/15 = 420/15
x=28
Answer:
good for u
Step-by-step explanation:
Answer: first answer choice (1/3) (p+45)
Step-by-step explanation:
to do this, factor out 1/3 from each element
so divide 1/3 p by 1/3 and 15 by 1/3
(1/3 p) / (1/3 ) = p
15 / (1/3) = 15 * 3 = 45
now put 1/3 outside of the parentheses
(1/3) (p+45)
Answer:
The value of x = 513
Step-by-step explanation:
Let x, y, and z be the three numbers
Given
Assuming x be the number which is 50% more than the sum of the other two numbers.
i.e.
(150)% of (y+z) = 1.5(y+z)
y + z = x/1.5
As we know that
substituting y + z = x / 1.5 in the equation
Multiply both sides by 1.5
Divide both sides by 2.5
Therefore, the value of x = 513
