Answer:

Step-by-step explanation:

42:7=ED:24

cross multiply 42 into 24.

Then divide by 7

you will get ED

Then use pythageorous theorem.

Ed square + 42 square=Ef square

Then do square root of Ef square

What’s the length of three pipes, when combined they equal 72m, how do I find the answer

allochka39001 [22]

Answer:

Each pipe is 24m

Step-by-step explanation:

Given:

three pipes
combined equal 72m
let the variable x represent the length of 1 pipe

Algebraic Expression:

3 pipes times length equals 72m (the total length)

3x = 72, we want x to be alone so divided both sides by 3

3x / 3 = 72 / 3

x = 24

The figure shows two intersecting lines and measures of the resulting angles write an equation to help you solve for x , then fi

ehidna [41]

Given:

Given that two lines are intersecting at the point.

The angles (3x - 8)° and (2x + 12)° are the angles formed by the intersection of the two lines.

We need to determine the equation to solve for x and the value of x.

Equation:

The two angles (3x - 8)° and (2x + 12)° are vertically opposite. Hence, the vertically opposite angles are always equal.

Hence, we have;

$3x-8=2x+12$

Hence, the equation is $3x-8=2x+12$

Value of x:

The value of x can be determined by solving the equation $3x-8=2x+12$

Thus, we have;

$3x-8=2x+12$

Subtracting both sides of the equation by 2x, we get;

$x-8=12$

Adding both sides of the equation by 8, we get;

$x=20$

Thus, the value of x is 20.

Hence, the equation and the value of x are $3 x-8=2 x+12 \ and\ x=20$

Thus, Option D is the correct answer.
