Answer:

2x-11

Step-by-step explanation:

The product of something means multiplication, and since we are only given one number we can use the variable x to represent it. And minus 11 is obviously subtraction, so we can put together the expression 2x-11.

4. Sam's parents are teachers who commute 45 miles roundtrip to work 5 2 days a week. His parents spend $38 on gasoline each wee
Marat540 [252]
<h2>Answer:</h2><h2>The correct option is d. (i) and (ii)</h2>

Step-by-step explanation:

The total miles covered per day = 45

No of commuting days in a week = 5

Total miles in a week = 45 * 5 = 225

The total amount spent on gasoline = $ 38

Cost of gasoline per gallon = $ 2.48

The number of gallons consumed per week = \frac{38}{2.48} = 15.32 gallons of gasoline per week.

This confirms (ii) statement

The amount spend on gasoline per mile = \frac{38}{225} = $0.17

This confirms (i) statement

The number of miles per gallon of gasoline = \frac{225}{15.32} = 14.68 miles

The statement (iii) is false.

Answer:

x=75°and y=x= 75°

Step-by-step explanation:

Reason: opposite angles are equal and how I got 75 is by drawing an extension line and finding the other angle (i.e. angle on a straight line=180) so 180-105=75.

Simplify 2x 2 - y for x = 3 and y = -2. A:10 B:16 C:20 D:14
balandron [24]

Answer:

<h2>20</h2>

Step-by-step explanation:

Given,

X = 3

y = -2

Now,

2 {x}^{2}  - y

Plugging the value of X and y

2 \times  {(3)}^{2}  - ( - 2)

Calculate the product

= 2 \times 9 - ( - 2)

= 18 - ( - 2)

= 18 + 2

= 20

Hope this helps...
