Answer:

A. y = 3x - 2

B. 3x - y = 2

E. y=2(x + 3)

Step-by-step explanation:

Let's say the larger number is y and the smaller number is x.

From the sentence "A larger number is double the sum of 3 and a smaller number", we can write the equation: y = 2 * (3 + x).

From the sentence "The larger number is 2 less than 3 times the smaller number", we can write the equation: y = 3x - 2.

With the second equation (y = 3x - 2), we can write this as: 3x - y = 2.

Thus, the choices that will work are A, B, and E.

Hope this helps!

Nadia has £5 to buy pencils and rulers. Pencils are 8p each. Rulers are 30p each. She says “I will buy 15 pencils. Then I will b
guapka [62]

Answer:

Total pencils: 17

Total rulers: 15

Step-by-step explanation:

"I will buy 15 pencils."

15 * 8p = £1.20

15 pencils

"Then I will buy as many rulers as possible."

£5 - £1.20 = £3.80

£3.80/30p = 12 remainder 20p

12 rulers

"With my change, I will buy more pencils.”

20p/8p = 2 remainder 4 p

2 pencils

Total pencils: 17

Total rulers: 15

Can someone help me?

Answer:

y = 2.1x +5, 21 miles

Step-by-step explanation:

We will denote miles as "x"

Since she tipped the driver $5, that is a flat rate and that will be our y-intercept. Since it costs $2.10 per mile, we need to multiply that number by the number of miles

So our equation will be y = 2.1x +5

In order to figure out how many miles Ann lives from the airport, we need to substitute y for her grand total that she was charged

This gives us 49.10 = 2.10x + 5

First we need to subtract 5 from each side to get 44.10 = 2.10x

We then need to divide both sides by 2.10 to get 21 = x

Ann drove 21 miles

Annette [7]

Answer:

The quotient is 48.

Step-by-step explanation:

Estimate the quotient using compatible numbers:

45 (or I guess any number close the answer above, not sure tbh)

Multiply the estimate by 21:

945

45*21

Is the estimate to high or too low?

too low

Adjust and continue until the product is 1008.

1008/21=48

Have a good day/evening! I hope my answer is correct!
