Answer 1

4x+2+2x+10 = 90

6x + 12 = 90

x = 90-12/6

= x = 13

MARK ME AS BRAINLIEST

Answer 2

Answer:

x= 13

Step-by-step explanation:

4x+2+2x+10=90

collect like terms

4x+2x+10+2=90

6x+12=90

collect like terms again

move 12 to the other side then the sign will change to minus -

6x=90-12

6x=78

divide both sides by 6

6x/6=78/6

x=13

If you can solve this AND show your work you get brainlist.

Answers

Answer:

Area of the circle: 78.54in^2

Plywood thrown away: 21.46 in^2

Step-by-step explanation:

So the area of the square is 100 in. To find the area of a circle, you use the formula (pi)r^2 where r is the radius, in this instance it is 1/2 of ten which is 5. Then, plug it into the formula which will get you (rounded to the nearest hundred) 78.54in^2. Then, subtract from the total plywood area. Please mark brainliest :)

Answers

Answer:

0=0

This means it is true for all x

Step-by-step explanation:

-5 + 5 (x-7) = -40 + 5x

Step 1: 5x-40=-40+5x

Step 2: Add 40 to both sides

5x-40+40=-40+5x+40

Step 3: Simplify

5x=5x

Step 4: Subtract 5x from both sides

5x-5x=5x-5x

Step 5: Simplify

0=0

Both sides are equal

It’s B, and C because 1 x 9 is 9 and 9 x 3 is 27 which proves its incorrect.

And 1 x 5 is 5 and 3 x 5 is 15 so its correct.

Lastly, 1 x 4 is 4 and 3 x 4 is 12 so that proves that this is correct.

A rock climber ascends 18 3/4 feet to the top of a rock ledge. He descends 8 1/8 feet and takes a break on a rock outcrop. Write and then evaluate an addition expression to show how much further the rock climber must descend to reach his original level. Enter the correct answers in the boxes.

Answers

Answer:

3

Step-by-step explanation:

The rock climber must descend 10 5/8 feet to reach his original level.

What is the fraction?

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

To evaluate this expression, we first need to convert the mixed numbers to fractions. 18 3/4 is equal to 18 + 3/4 = (72+ 3)/4 = 75/4.

Similarly, 8 1/8 is equal to 8 + 1/8 = (64 + 1)/8 = 65/8.

So, the rock climber must descend :

= 75/4 - 65/8

= (75x8 - 65x4)/(48)

= (600 - 260)/32

= 340/32

= 10 5/8 feet to reach his original level.

Thus, to ascend to his original level, the rock climber must descend 10 5/8 feet.
