Answer:

A.  1/12.

Step-by-step explanation:

Orville and Wilbur  ate 1/3 + 1/4

= 4/12 + 3/12

= 7/12 of the pizza.

So there was 1 - 7/12 = 5/12 of the pizza left.

So Ruth ate 5/12 * 1/5

= 5/60

= 1/12.

Solve p=10a+3b for a
Gre4nikov [31]

Answer:

a = (p - 3b)/10

Step-by-step explanation:

Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS (Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction).

p = 10a + 3b

First, subtract 3b from both sides.

p (-3b) = 10a + 3b (-3b)

p - 3b = 10a

Next, isolate the a. Divide 10 from both sides.

(p - 3b)/10 = (10a)/10

(p - 3b)/10 = a

a = (p - 3b)/10 is your answer.

How to Find x value: 9-0.75(x+8)-5=-6.5
Dahasolnce [82]
Here's how to find the value of x:

<span>9 - 0.75 ( x + 8 ) - 5 = -6.5      find the difference of 9 - 0.75

</span><span>8.25 ( x + 8 ) - 5 = -6.5           add 5 to both sides
</span>
8.25 ( x + 8 ) = -1.5                distribute 8.25 to x and 8

8.25x + 66 = -1.5                    subtract 66 from both sides

8.25x = -67.5                          divide both sides by 8.25

x = 18.18181818......            the value of x is 18 2/11

hope this helps
