Answer:

$\boxed{x$

Step-by-step explanation:

→ Expand out the brackets

3x + 3 < 18

→ Minus 3 from both sides to isolate 3x

3x < 15

→ Divide both sides by 3 to isolate x

x < 5

Answer:

Question 1:

5 pints per hour

Question 2:

480 tons per day

Question 3:

12 miles per gallon of gasoline

Step-by-step explanation:

Question 1:

<h2>In the morning;</h2>

A farm worker packed 3 pints of grapes every 4 minutes.

1 minute = $\frac{1}{60}$ hours

Packing rate in pints per hour = 3 pints ÷ $\frac{4}{60}$ hours = 45 pints per hour

<h2>In the afternoon;</h2>

She packed 2 pints of grapes every 3 minutes.

Packing rate in pints per hour = 2 pints ÷ $\frac{3}{60}$ hours = 40 pints per hour.

The difference between her morning and afternoon packing rates (in pints per hour) = 45 pints per hour - 40 pints per hour = 5 pints per hour

Question 2:

A recycling plant processes an average of $\frac{1}{3}$ tons of glass each minute.

1 hour = 60 minutes

The number of tons of glass processed in 1 hour is:

$\frac{1}{3}$ × 60 = 20 tons of glass in 1 hour.

1 day = 24 hours

Number of tons of glass processed in a day = 20 tons × 24 = 480 tons

Question 3:

A vehicle uses 1 $\frac{1}{8}$ gallons of gasoline to travel 13 $\frac{1}{2}$ miles.

Per 1 gallon of gasoline the vehicle will travel:

1 × 13 $\frac{1}{2}$ ÷ 1 $\frac{1}{8}$ = 12 miles

The equation y 10x describes the amount of money Sandra earns, where x is the number of hours she

tester [92]

Answer:

a) $10 per hour

b) Sandra

Step-by-step explanation:

Complete Question:

The equation y 10x describes the amount of money Sandra earns, where x is the number of hours she works and y is the amount of money she earns

The table shows the amount of money Susan cams for different numbers of hours worked

Susan's Earnings

Time (h) Money Earned

5 40

8 64

10 80

(a) How much money does Sandra eam per hour? Show your work

(b) Who earns more per hour? Justify your answer

Answer:

y = 10x is sandra's equation. To find her hourly rate, we need to find how much she earns in "1" hour. Since x is hours, we plug in x = 1 and find y (which is her pay).

y = 10x

y = 10(1)

y = 10

$10 is Sandra's hourly rate.

To find who earns more per hour, we need to find the hourly rate of Susan as well from the table. Then compare.

5 hours = $40 so per hour is 40/5 = 8

8 hours is 64, so per hour 64/8 = 8

10 hours is 80, so 80/10 = 8

The table is justified at $8 per hour.

We know Sandra earns $10/hr and Susan earns $8 per hour. So Sandra earns more per hour.
