Answers

Answer:

x=14

y=37

Step-by-step explanation:

9x+12+3x=180

12x+12=180

      -12   -12

12x=168

divide both sides by 12 and

x=14

then plug in 3(14)+4y-10=180

42+4y-10=180

32+4y=180

4y=148

y=37

X=15
Y=36.25


9x+12+3x=180
-12 -12
12x=180
divide by 12 both sides
X= 15

4y-10+3x=180
Substitute x for 15
4y-10+45=180
4y+35=180
-35 -35
4y=145
divide 4 both sides
Y=36.25

Which graph represents the solution of 3y-9≤6x?

Answers

A is correct when you do this B looks close but it’s A

The graph that represents the solution of 3y - 9 ≤ 6x is option A.

Option A is the correct answer.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal =

Greater than and equal=

We have,

3y - 9 = 6x

We can find the following coordinates.

When x = 0,

3y - 9 = 0

3y  9

y = 3

When y = 0,

3y - 9 = 6x

-9 = 6x

x = -9/6

x = -3/2

x = -1.5

Thus,

The graph on option A represents the solution.

Then you would multiply 38 x 2to get 76

14 + 76 = 90

Answers

Answer:

y=4

Step-by-step explanation:

4y+3=19

=4y=19-3

=y=16/4=4

Answer:

a) y = 4

b) n = 4

Step-by-step explanation:

a) 4y + 3 = 19

Subtract 3 from both sides.

4y = 16

Divide both sides by 4.

y = 4

b) Is the 1 apart of the equation? If not, these are the steps to find n.

2n - 3 = 5

Add 3 to both sides.

2n = 8

Divide both sides by 2.

n = 4
