Answer:

Step-by-step explanation:

54-7=47

I'm assuming we are trying to find Rita's score. We know that the total is 54. "The sum" refers to addition, so we must reverse the problem to find her score

54- 7= 47

Total - 7 = her score

- Paul wants to figure out the fuel consumption of his new SUV in the city. He made

Vesnalui [34]

Answer:

a.15.1 L/100 km; b $72.75; c. $51.34

Step-by-step explanation:

(a) Fuel consumption

Fuel used = 75 L

Distance travelled = 6096 km - 5600 km = 496 km

$\text{Fuel consumption} = \dfrac{\text{75 L}}{\text{496 km}} \times \dfrac{\text{ 100 km}}{\text{100 km}} = \dfrac{\text{15.1 L}}{\text{100 km}}$

(b) Cost to fill tank

$\text{Cost} = \text{75 L} \times \dfrac{\text{\$0.97}}{\text{1 L}} = \$72.75$

(c) Cost per week

i. Calculate the volume of gasoline

$\text{Volume} = \text{350 km} \times \dfrac{\text{75 L}}{\text{496 km}} = \text{52.9 L}$

ii. Calculate its cost

$\text{Cost} = \text{52.9 L} \times \dfrac{\text{\$0.97}}{\text{1 L}} = \$51.34$

The sum of twice a number and 15 is-42

Ganezh [65]

The equation is -42=2a+15
I just picked the variable to be a
Now I would divide 2a by 2 to make it just a
And divide -42 by 2 to make it -21. Then you would have -21=a+15
Subtract 15 from 15 to cancel it out
And then subtract 15 from -21 to get
-36=a
the variable is -36
