Answers

Answer:

I think the answer is 18 because 20+18=38 and 7x2= 14

Then you would multiply 38 x 2to get 76

14 + 76 = 90

Step-by-step explanation:

The correct answer is 20. This is because a supplementary angle is shown, so we can use 7x+(x+20)=180 to solve. You can see my work below.

WILL GIVE BRAINLIEST!!! A rectangular field has an area of 4200 feet. Let the length of the field be (x+2) and the width be (x-3). Find the length and width of the field by writing a quadratic equation and solving using completing the square.

Answers

Equation: 2(x+2)(x-3)=4200

(x+2)(x-3)=4209

this is the equation because area is base x height. so those two sides being multiplied will give you 4209. so when you solve those two problems you will then multiply them and get 4209

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.

Solve for the given variable.
a. 4y + 3 = 19

b. 1
2n - 3 = 5

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

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
