Answer:
13
Step-by-step explanation:
Divide 12 by 3 first because of (PEMDAS) you get 4 tge add that to the 9 the you get 13.
P = parentheses
E = exponent
M = multiplication
D = division
A = addition
S = subtraction
Answer:
2,500 ÷ 10
Step-by-step explanation:
Let's evaluate each expression one after the other and find out what they both gives us, then we'd now pick or select the one that doesn't give the required answer.
For 2,500 × 10
2500*10 = 25000
For 250,000 ÷ 10
250000/100= 25000
For 2,500 ÷ 10
2500/10= 250
So from the look of the results,
The one that gave us the odd result is
2,500 ÷ 10, and that's our answer.
In constructing the equation, you need to know the following:
1. What don't we know? How many minutes you must talk to have the same cost for both calling plans. So, let x be the number of minutes.
2. What do we know? Plan 1 charges $17.50 per month plus $0.17 per minute used and Plan 2 charges $32 per month plus $0.07 per minute used.
So the equation must look like this: 17.50 + .17x = 32 + 0.07x
Solving the equation:
1. Multiply both sides by 100
(100) 17.5 + .17x = 32 + 0.07x (100)
1750 + 17x = 3200 + 7x
2. Subtract 1750 from both sides
1750 + 17x - 1750 = 3200 + 7x - 1750
17x = 7x +1450
3. Subtract 7x from both sudes
17x - 7x = 7x + 1450 - 7x
10x = 1450
4. Divide both sides by 100
10x / 10 = 1450/10
x= 145 minutes
145 minutes is the number of minutes you must talk to have the same cost for both calling plans.
