Jo makes 170 minutes call. There are 150 free ones
170 - 150 = 20
20 minutes are "what Jo has to pay"
Jo sends 182 texts. There are 150 free ones
182 - 150 = 32
32 texts are "what Jo has to pay"
Monthly charge = 16p, 13p for each extra minute, 15p for each extra text.
13(20) = 260p
15(32) = 480p
480p + 260p + 16 = 740p + 16
740p + 16 is your answer (if p = pounds, add 16 to it, i'm not sure what p stands for though. If it is cents, divide 100 from 740 and take out the p, then add total to 16 to get answer.)
hope this helps
Answer:
The third answer is correct
Step-by-step explanation:
Answer:
1, 3, 4, and 10
Step-by-step explanation:
To get a y value, substitute the x value into the equation they gave you (y = 3x - 5). For the x value 2:
y = 3(2) - 5
y = 6 - 5
y = 1.
To get a missing x value, solve for x in the equation they gave you. You were given the y value, so you can substitute that into the equation.
(4) = 3x - 5
Add 5 to both sides
9 = 3x
Divide both sides by 3
3 = x
Do the same with 7
(7) = 3x - 5
Add 5
12 = 3x
Divide by 3
4 = x
For the last one, you're given x so substitute it into the equation:
y = 3(5) - 5
y = 15 - 5
y = 10
Answer:
Step-by-step explanation:
-2(6+s) ≥ -15 -2s
step 1: first remove the parenthesis
-12 - 2s ≥ -15 -2s
step 2: add +12 to each side to combine like and unlike terms
-12 - 2s + 12 ≥ 15 - 2s +12
= -2s ≥ 27 - 2s
step 3: then add +2s to each side to obtain unknown sides
-2s + 2s ≥ 27 -2s + 2s
0 ≥ 27 + 0
Answer: No solution
In Summary
Step 1 Eliminate fractions by multiplying all terms by the least common denominator of all fractions.
Step 2 Simplify by combining like terms on each side of the inequality.
Step 3 Add or subtract quantities to obtain the unknown on one side and the numbers on the other.
Step 4 Divide each term of the inequality by the coefficient of the unknown. If the coefficient is positive, the inequality will remain the same. If the coefficient is negative, the inequality will be reversed.
Step 5 Check your answer.
