General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define equation</u>
4x + 10 = 3x + 37
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 3x on both sides: x + 10 = 37
- Subtract 10 on both sides: x = 27
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 4(27) + 10 = 3(27) + 37
- Multiply: 108 + 10 = 81 + 37
- Add: 118 = 118
And we have our final answer!
To find this answer multiply the cost of the ice cream by 18%/100, or .18
$154 x .18 = $27.72
Answer:

Step-by-step explanation:
Answer:
In short, 0 is the only number such that for any number x, x + 0 = x.
Step-by-step explanation:
So, the reason that any number to the zero power is one is because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1.
Given the statement, "If
is odd, then
is odd," its contrapositive claims that, "If
is not odd, then
is not odd."
So assume
is not odd, i.e.
is even. This means there is an integer
for which
. Squaring this gives
.
Well, we can write
, and
is just another integer, which means
must be even.
