Answer:
729/8
Step-by-step explanation:
4 1/2 * 4 1/2 * 4 1/2 = (9/2)^3 = 729/8
Answer:
a=4
Step-by-step explanation:
ax − 4 = 2y
We need to get the equation is slope intercept form y= mx+b.
Lets solve for y
Divide each side by 2
a/2 x - 4/2 = 2y/2
a/2 x -2 = y
or y=a/2 x -2
The slope is a/2 and the y intercept is -2
We want a slope of 2 so a/2 =2
a/2=2
Multiply each side by 2
a/2 * 2 =2*2
a =4
Answer:
x + 15
Step-by-step explanation:
The problem is in word form. Write the problem in <u>algebraic form</u>, which means using numbers and symbols (like + - ÷ x).
Take the key word:
'sum' - This means the answer when you <u>add numbers</u>. To add you use the + <u>plus sign</u>.
The sum of a number and 15 means adding a number and 15.
There is no equal sign because the question does not say "equals" or "is".
<u>Choose a variable</u> to represent "a number". I will choose the letter 'x'. Add 15 to 'x'.
x + 15
To figure this out, just multiply .825 by 1000.
0.825 x 1000 = ?
