Answer:

C.

Step-by-step explanation:

7 distributes and subtracted by 25

Answer: C
= 7·(s + d) - 25

Explanation;

Cost of each plant both buys = $7
No. of plants Stephanie wants to buy = s
Total cost of plants bought by Stephanie = 7·s
No. of plants Diego wants to buy = d
Total cost of plants bought by Diego = 7·d
Total cost = 7·s + 7·d
= 7·(s + d)
Discount applied through coupon = $25
So, Total cost of all their plants with discount = 7·(s + d) - 25

Stevic delivers newspapers. He has already earned $36 for each Sunday paper and $12 for each Saturday paper. He earns $4 for each Sunday paper. He earns $2.50 for each Saturday paper.


Fill in the blank spaces with (NUMBERS ONLY)

Answers

Answer:

Stevie earns $600 on Sunday and $217.50 on Saturday. Together it is 817.50 dollars.

Step-by-step explanation:

Sunday Newspaper:

36+4=40 dollars per Sunday Newspaper

40*15=600 dollars

Saturday Newspaper:

12+2.50=14.50 dollars per Saturday newspaper

14.50*15=217.50 dollars

600+217.5=817.50 dollars for 15 Sunday Newspapers and 15 Saturday Newspapers

Answer:

36, 12, 2.50, 726.5

Step-by-step explanation:

The last one only needs to be explained

36x+4 and 12x+2.50

If x= 15 you have to multiply it by 36 and 12

(36(15) +4) + (12(15) +2.50)

(540+4) + (180+2.50)

544+182.5

=726.5

What is 6x + 2y = 10 solve for y And if you would be so kind to add the slope and y-intercept thank youuuuu!!!

Answers

Answer:

y = mx + b

Where m is the slope and b is the y-intercept.

To do this we just solve for y.

Subtract 6x from both sides.

-2y = 10 - 6x

Divide both sides by -2.

y = -5 + 3x

m=3

The line has a slope of 3.

Answer: Y=mx+ b
