[Edit:}
Okay! So after you have 15+(21)÷3, you have to remember PEMDAS.
PEMDAS is the order in which you solve equations.
1. Parentheses: you solve everything in the parentheses first, all while following the rules of PEMDAS
2. Exponents: after you solve the things in the parentheses, you do the exponents.
3. Then you do Multiplication or Division, solving in the order from left to right.
4. After, you do Addition or Subtraction, solving in the order from left to right.
So using PEMDAS, we'll solve 15+(21)÷3.
We do division before addition, so 21/3 is 7.
Then you add 15 to 7 and get 22 as your final answer.
Hope this helps!
Answer:
16'1"
A) 6' + 5' + 3' = 14'
B) 10" + 4" + 11" =25" = 2'1"
A+B= 16'1"
1 Feet = 12 Inches
Answer:
x intercept: (4,0)
y intercept: (0,2 1/2)
Step-by-step explanation:
Use this formula a2 − b2 = (a + b)(a − b)
<span>(x+1)^2-(x-1)^2 in this case, a = x+1, b = x-1</span>
<span>= [(x+1) + (x-1)] * [(x+1) – (x-1)]</span>
=(x +1 + x – 1) *(x +1 – x +1)
= 2x * 2
<span>=4x</span>
Answer:
option 2
52.1
Step-by-step explanation:
Peak season economy air fare: $526.30
30-day excrusion ship fare: $345.95
To know the percentage with respect, we only have to put the most expensive value divided by the smallest value multiplied by one hundred, this will tell us what percentage you have with each other
526.30 / 345.95 * 100 =
1.5213 * 100 =
152.13
Now to know only the percentage that increased, we have to subtract 100 that would be the base value
152.13 - 100 = 52.13
52.1
