¹/₂ Moussa delivered: of the newspaper on his route in the first hour, and of the rest in the second hour. Question:What fraction of the newspapers did Moussa deliver in the second hour?The Process:Step-1Let us design a diagram that matches the initial conditions.1 unit represents 1 part of all newspapers delivered by Moussa.Moussa delivered of the newspaper on his route in the first hour, that is or 3 of 8 units.The rest of the newspaper after the first hour of delivery is or 5 of 8 units.So, there are of the newspapers left.Step-2Next, Moussa delivered of the rest in the second hour. We saw that the remainder of the newspaper was 5 units, i.e., .So, in the second hour, Moussa delivered 4 units of the remaining 5 units, i.e., .Recall the total number of newspaper units delivered by Moussa is 8 units, while in the second hour 4 units are delivered.So, we can write the fraction of the newspapers did Moussa deliver in the second hour.Simplify it. The numerator and denominator are equally divided by 4.Thus, Moussa delivered of the newspapers in the second hour.- - - - - - - - - -Quick StepsSimplify it. The numerator and denominator are equally divided by 20.Another way, We crossed out 5 with 5 and also 4 with 8.Learn moreWhat fraction of the property is used for the garden? brainly.com/question/1011853 How much water did Patrick drink altogether brainly.com/question/3063185 How many total yards did he have? brainly.com/question/2443310Keywords: Moussa, delivered, 3/8 of the newspaper, on his route, in the first hour, 4/5 of the rest, in the second, what fraction, units, diagram, the numerator and denominator
The numbers are 17 and -5
Step-by-step explanation:
The given is:
- A first number plus twice a second number is 7
- Twice the first number plus the second totals 29
We need to find the 2 numbers
Assume that the 1st number is x and the 2nd number is y
∵ x represents the 1st number
∵ y represents the 2nd number
∵ The first number plus twice the second number is 7
∴ x + 2y = 7 ⇒ (1)
∵ Twice the first number plus the second totals 29
∴ 2x + y = 29 ⇒ (2)
Now we have system of equations to solve it
Multiply equation (1) by -2 to eliminate x
∴ -2x - 4y = -14 ⇒ (3)
- Add equations (2) and (3)
∴ -3y = 15
- Divide both sides by -3
∴ y = -5
Substitute the value of y in equation (20 to find the value of x
∵ x + 2(-5) = 7
∴ x - 10 = 7
- Add 10 to both sides
∴ x = 17
The numbers are 17 and -5

The third one makes the most sense to me, good luck
One temperature colder that -7.2 F would be -9 F.
-9 < -7.2
The -9 would be 1.8 units to the left of -7.2 on the number line.
