Answer:
70*20=1400/2= 700. that's all
Answer:
x = 73
General Formulas and Concepts:
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define equation</u>
(180 - x) + (90 - x) = 124
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 270 - 2x = 124
- Subtract 270 on both sides: -2x = -146
- Divide -2 on both sides: x = 73
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: (180 - 73) + (90 - 73) = 124
- Subtract: 107 + 17 = 124
- Add: 124 = 124
Since you are trying to find the price of 1 roll of tape
1.28 divided by 2 = 0.64
Since you are trying to find the price of 2 notepads
.87 divided by 3 = 0.29 + 0.29 = 0.58
Since you need the price of 2 highlighters
1.59 x 2 = 3.18
2 pens = 1.98 is a given so
0.64 + 0.58 + 3.18 + 1.98
= 6.38
Answer:
The average rate of change is 8
Step-by-step explanation:
Mathematically, we have the average rate of change over a given interval as;
f(b) - f(a)/b-a
Where the interval is [a,b]
With respect to this question, a = 3 and b = 5
f(a) = f(3) = 3^2 - 4 = 9-4 = 5
f(b) = f(5) = 5^2 - 4 = 25-4 = 21
Thus, the average rate of change over the intervals will be;
(21-5)/(5-3) = 16/2 = 8
