3. Angle 1 and angle 2 are complementary angles. The measure of angle 1 is 18". The
measure of angle 2 is 12x. Find the value of x.

Answers

Answer 1

Answer:

x = 6

Step-by-step explanation:

Complementary angles always equal 90 degrees so something multiplied by 12 will have to equal something that will add up with 18 to get 90 so

12 × 6 = 72 and 72 + 18 = 90 Hope this helps you!

u-5=-8 is tell solution of equation ​

Answers

Answer:

u = -3

Step-by-step explanation:

Solve for u:

u - 5 = -8

Hint: | Isolate terms with u to the left hand side.

Add 5 to both sides:

u + (5 - 5) = 5 - 8

Hint: | Look for the difference of two identical terms.

5 - 5 = 0:

u = 5 - 8

Hint: | Evaluate 5 - 8.

5 - 8 = -3:

Answer: u = -3

answer
u = -3

step by step
u=-8+5
u =-3

The slope between two points (2,b) and (1, -2) is 4. Find b.

Answers

Answer:

b=2

Step-by-step explanation:

To get slope given two points, take the difference of the y values and divide it by the difference of the x values.

(This is also called change in y over change in x, or rise over run)

b-(-2)/2-1=4

b+2/1=4

b+2=4

b=2

Answer:

114cm²

Step-by-step explanation:

Okay, so you can split this thingy up into a rectangle and another rectangle, so that's what we're going to do (see pic below)

So now we take off that 7 from the 13:

13 - 7 = 6

So now we find the area of that little area:

6 x 5 = 30

Now we do the other rectangle:

12 x 7 = 84

Now we add them together:

84 + 30 = 114

So the area of the shape is 114cm²

hope this helps:)

Bernice uses the equation C = 2h + 8 to find the total cost, C, in dollars, of renting a boat for h hours. If Bernice does not spend more than $32, what is the maximum number of hours she can rent the boat?
a 8
b 12
c 20
d 22​

Answers

Answer:

A

Step-by-step explanation:

Since she's not spending more than $32, the equation is 2h + 8 ≤ 32.

Isolate h to find the maximum number of hours she can rent the boat:

2h + 8 ≤ 32

First, subtract 8 from both sides.

2h ≤ 16

Then divide both sides by 2.

h ≤ 8

h, the number of hours, must be less than or equal to 8, so 8 is the maximum number of hours Bernice can rent the boat for.
