A value of 600 increases by 15%.

What is the new value?


A
645

B

C
690

D
720

Answers

A. 645 because if you divide like quarters you will get 645
The answer is c because you can do the method of cross multiplication 15/100 and 0/600. You multiply the 600 and 15 and divide by 100 which will equal 90 and then since it’s a increase you ADD 600 and 90 which you get the number 690

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

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

What property was applied to solve the equation below?

0.36 x = negative 1.8
0.36 (divided by 0.36) x = negative 1.8 (divided by 0.36)
x = negative 5

Answers

Answer:

Division property

Step-by-step explanation:

The property which states that we can divide both side of the equation by the same non-zero number is called the division property of equality.

The goal of dividing an equation is to isolate the unknown variable on one side.

For example, let the equation be:

2×x=10

Since the unknown variable x is being multiplied by the number 2, to isolate the variable an inverse operation needs to be applied - division:

2×x÷2=10÷2

Careful! Never forget to write the same operation on both sides of the equation! When doing so, the solution of the equation stays the same, i.e. we get an equivalent equation.

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
