When isolating a variable in the equation -3y=2x-7, how do you get rid of the -3 in front of the y?

Answers

Answer 1

Answer:

Answer: You divide both sides by -3.

Step-by-step explanation:

We're asked to solve the equation: $\sf{-3y=2x-7}$ .

To do this, divide both sides by -3:

$\sf{-3y=2x-7}$

$\sf{y=\cfrac{2x-7}{-3}$

Simplify

$\sf{y=-\cfrac{2x-7}{3}}$

Therefore, that's our answer.

Answer 2

Answer:

Answer:

divide both sides by - 3

Step-by-step explanation:

given the equation

- 3y = 2x - 7

to isolate y then divide both sides by - 3

$(-3)/(-3)$ y = $(2x-7)/(-3)$ , that is

y = $(2x-7)/(-3)$

y = $(2)/(-3)$ x + $(-7)/(-3)$ = - $(2)/(3)$ x + $(7)/(3)$

CANT GET WRONGThe equation y = 4x + 4 describes the relationship between the quantities x and y. Are the quantities in a proportional relationship?
A) Yes, because the graph of the equation is a straight line.
B) No, because the graph of the equation is not a straight line.
C) Yes, because the graph of the equation passes through the origin.
D) No, because the graph of the equation does not pass through the origin.

Answers

Answer:

Option D is correct that is No, because the graph of the equation does not pass through origin.

Step-by-step explanation:

We have been given the equation:

y = 4x+4

The direct proportion means if equation follow: y=mx where m is the proportion or can say equation passes through origin.

Here, equation is y=mx+c not y=mx

In y=mx

We can see if x increases y will increase

And if x decreases y will decrease.

Therefore, Option D is correct that is No, because the equation does not pass through origin.

The correct answer would be D. because if the equation has a y-intercept (+4) than the line doesn't go through the origin.

What is the unitary method?

The unitarymethod is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that Dee spends $0.25, $0.30, $0.10 and $0.04.

We need to find the money she spend in all.

Therefore, we have to add all the expenditure

0.25 + 0.30 + 0.10 + 0.04 = 0.69

The total money she spend could be 0.69.

$( ((2)/(x) -1))/( ((1)/(x) -1))= (( (2-x)/(x)))/(( (1-x)/(x))) = (2-x)/(1-x)$ . Now the answers on your paper do not have this choice, but if you think about it, (2-x)=-1(x-2) and (1-x)=-1(x-1). This means that when you have (2-x)/(1-x), this also equals to (x-2)/(x-1), since the -1's cancel out. So, the answer is D.

Jillian is selling boxes of cookies to raise money for her basketball team. The 10 oz. box costs $3.50, while the 16 oz. box costs $5.00. At the end of one week, she collected $97.50, selling a total of 24 boxes. The system of equations that models her sales is below. x+ y= 24 3.50x + 5.00y = 97.50 Solve the system of equations. How many 10 oz. boxes were sold? a. 6
b. 9
c. 12
d. 15

Answers

we have to solve simultaneous equations.

x = 10 oz. boxes

y = 16 oz. boxes

simultaneous equations

x + y = 24 ---1)

3.50x + 5.00y = 97.50 ----2)

to solve for x we need to eliminate y, therefore we have to multiply 1st equation by 5

5x + 5y = 120 --3)

subtract 3) - 2)

5x - 3.50x = 120 - 97.50

1.50x = 22.5 x = 15

number of 10 oz. boxes are 15. answer is d.15

Answer:

d is the correct answer

How many times does 27 go into 1714???

Answers

Answer:

27/3 = 9

Step-by-step explanation:

"How many times does 3 go into 27?" is the same as asking "How much is 27 divided by 3?" Thus, the answer can be calculated as follows:

27/3 = 9"How many times does 3 go into 27?" is also the same as asking "What (x) do you multiply by 3 to get 27?" We solve the problem with an easy algebra equation:

3(x) = 27

x = 9

Tip: When you get a question like "How many times does 3 go into 27?", just think of it as how many times you can fit 3 into 27.

The answer on this page is rounded to the nearest decimal if necessary.

27 goes in to 1714 63.48 times
