As it is a straight line all the angles add up to 180 so 5s+18+48-a+8a-30= 180 so simplified 12a+36=180 then solve to get a=12.17 so then when u put 12.17 as a you get 5 * 12.17 +8 =78.85 then 48-12.17 which is clearly<78.85 then you do the final angle of 8*12.17-30 which is 67.36 so angle AOC is the biggest

(5a + 18) + (48 - a) + (8a - 30) = 180

5a + 18 + 48 - a + 8a - 30 = 180

5a - a + 8a + 18 + 48 - 30 = 180

12a + 36 = 180

12a = 180 - 36

12a = 144

a = 12

2 numbers a and B are graphed on a number line is it always sometimes or never true
prohojiy [21]
The answer is "sometimes".

 

If A = 3 and B = 1 then, A > B and A-B < A+B

 

On the other hand, If A = 3 and B = -1, then A > B but A-B is not less than A+B.

Could anyone help me with these?
lora16 [44]
Part A:

Derrick is incorrect.
A yard is equivalent to 3 feet.
Thus, 20 yards will be equivalent to 60 feet.

The width is 20 yard and 2 feet. It's the same as 60 feet and 2 feet, or 62 feet. Thus, Derrick is incorrect.

Part B:

Let's calculate the area of the parking lot.

We know the width is 62 feet from part A.
The length is 30 yards, or 90 feet.

Multiply the length and width to get the area in square feet.

90 \times 62=5580

The parking lot has an area of 5580 square foot.
It costs 2 dollars per square foot to repave the parking lot. Multiply the area by 2 dollars.

5580 \times 2=11160

It will cost $11,160 to repave the whole parking lot.

7x - 20 = 2x - 3(3x + 2)
kirill [66]

Answer:

7x-20=2x-3(3x+2)

We move all terms to the left:

7x-20-(2x-3(3x+2))=0

We calculate terms in parentheses: -(2x-3(3x+2)), so:

2x-3(3x+2)

We multiply parentheses

2x-9x-6

We add all the numbers together, and all the variables

-7x-6

Back to the equation:

-(-7x-6)

We get rid of parentheses

7x+7x+6-20=0

We add all the numbers together, and all the variables

14x-14=0

We move all terms containing x to the left, all other terms to the right

14x=14

x=14/14

x=1

Number 8 please it will help a lot
pickupchik [31]
Well it all depends on the object you are using but in this case lets say remote control cars. You can have an example like "we drove the car around the building twice. the first time it was -8 than how fast it was supposed to go. the second time it was 9. In which round was the car faster?" I dont think i helped very much but i hope i did
