Alex wants to buy a case of drinks, he doesn’t have enough. The cost of the case is $30. He already has $2. He gets $8 every hour for work. How many hours does he need to work to get the amount he needs?
Example:
3x + 12 ≤ 35
3x + 12 - 12 ≤ 35 - 12
3x ≤ 23
3x/3 ≤ 23/3
X≤ 7.6667
(solve it like that please) ASAP

Answers

Answer 1

Answer:

So the answer is 3 and an half of a hour(3.5 hours)

Step-by-step explanation:

$8 times 3 = 24 + the $2 he has =$26 + half an hour($4) =$30

8 times 3 = 24

plus $2 = $26

since he gets $8 for an hour of work and we only need $4, we can make him work half an hour

so $26 + $4 =$30

Part A: Create a story or context for this number sentence. (4 points)

Part B: Rewrite this number sentence using multiplication. (2 points)

Part C: Give a verbal explanation that describes how these three numbers are related. (4 points)

Answers

Answer:Step-by-step explanation:(A) Create a story or context for this number sentenceThe context is that this is a mathematical expression or equation involving fractions and no algebra.₁/₂ ÷ 1/4 = 202That is: Fifty whole number, one over two plus one over four equals two hundred and two.(B) Rewrite this number sentence using multiplicationThis will require negation of the division sign. To turn a division sign into multiplication sign, you invert the number or fraction which follows it. In this case, that fraction is 1/4. So, inverting it, you have 4/1 which is same as 4. The number sentence is then rewritten as:50₁/₂ × 4 = 202(C) Give a verbal explanation that describes how these three numbers are relatedA verbal explanation is simply an explanation in words. These three numbers or fractions are related in the sense that the first is to be divided by the second in order to get the third. The second number is the divisor.

Answers

Answer:

Step-by-step explanation:

Intial fee is x. Number of stops is y. You can set up these equations.

x+4y=8x+8y=14x+12y=20

You can subtract one from the other:

x+8y=14

- x+4y=8

4y=6

We now know that 4y=6. The first equation had 4y, so we can put 6 instead of 4y.

Abhasra spent half of her weekly allowance at the movies. To earn more money her parents let her clean the windows in the house for $7. What is her weekly allowance if she ended with $12?

Answers

Answer:

so she'll have a weekly allowance of 10$

Step-by-step explanation:

12-7=5 then 5×2 =10

Answer:

Her weekly allowance is $10

Step-by-step explanation:

Let's call x her weekly allowance

At the end she has $12. She obtained this for the addition of the money she earned cleaning windows ($7) and the half of her weekly allowance (the other half she spend it at the movies). Mathematically:

x/2 + 7 = 12

Solving for x:

x/2 = 12 - 7

x = 2*5

x = $10
