Answer:

So we know the sum of two numbers, let them be x and y, is equal to 36:

x + y = 36

And on of them, for example, y, is equal to 10:

x + 10 = 36

Now, the only thing we need to do is solving the equation to find x:

x + 10 = 36

We pass the 10 substracting to the right:

x = 36 - 10

And now, we substract:

x = 26

Now we know one number is 10 and the other is 26, so we can verify we have done all correctly

26 + 10 = 36 (TRUE)

Now we know we have done the exercise well.

Explain why 82.5 + 8(0.25x) = 338.5 is equivalent to 82.5 + 2x = 338.5

VARVARA [1.3K]

Answer:

Multiply 0.25x by 8

Step-by-step explanation:

82.5 + 8(0.25x) = 338.5

Multiply 0.25x by 8 we get,

8 × 0.25x = 2x

Thus, 82.5 + 2x = 338.5

2(10r-7)-2(1+10r)=-r+2r

DerKrebs [107]

Answer:

r = -16

Step-by-step explanation:

We will use "distributive" property and "adding like terms" concepts in solving for the unknown variable "r".

The distributive property is:

a(b+c) = ab + ac

2(10r-7) = 20r - 14

also

-2(1+10r) = -2 - 20r

So, our equation becomes:

$2(10r-7)-2(1+10r)=-r+2r\\20r-14-2-20r=-r+2r$

Now we add like terms and move variables (r) to one side and numbers to another. Like terms mean:

3r + 5r = (3+5)r = 8r

So, we have:

$20r-14-2-20r=-r+2r\\-16=r\\r=-16$

So,

the value of r is -16

The hose is 2 inches in diameter. What circumference does the plug need to be?

scoray [572]

Answer:

6.28

Step-by-step explanation:

This problem bother on the mensuration of flat shapes, a circle.

Volume v =

Diameter d= $2inches$

Radius r = $=\frac{diameter}{2} = \frac{2}{2} = 1 in$

Since we are required to solve for the circumference of a circle

The expression for the circumference of a circle is given as

$C= 2\pi r$

$C= 2*3.142*1\\C= 6.28$

The question insist that we type just a number hence the circumference $6.28$ of the plug is 6.28
