Answers

Answer 1

Answer: please do not ask questions twice, just wait till someone answers it

so
100-15=85
discount 15 is the same as finding 85%

100-20=80
20% off is the same as finding 80%

180*.85=153
200*.80=160

153<160

sport city is better deal

Answer 2

Answer: 15% of 180 is (180 * 0.15) = 27.

180 - 27 = $153 paid.

20% of 200 = (200 * 0.2) = 40.

200 - 40 = $160 paid.

Therefore Sport City offered the better deal.

Mowed 6 yards for $40.00 ,What's the rate and the unit rate?

Answers

The only thing between you and the answer is a division problem, you divide 40 by 6 and find 6.6666, a repeating decimal, and you answer. For every one yard this person mows, he/she earns $6.66 (with a line under it that signifies a repeating decimal) dollars an hour.

The rate is y=6.66x to solve do 40/6 this gets you 6.666666667 which is 6.66

Solve for u -5/2u = 15

Answers

Answer:

U = -1/6

How to solve:

Multiply both sides by 2U to get rid of the denominator and you should end up with

$- 5 = 15(2u)$

then multiply and devide to get your U by itself.

you should then get

$u = - (1)/(6)$

after symplifying.

Answer:

Answer:

u=−10

Step-by-step explanation:

Let's solve your equation step-by-step.

u−5/2u=15

Step 1: Simplify both sides of the equation.

u−5/2u=15

u+−5/2u=15(u+−52u)=15

(u+−52u)=15(Combine Like Terms)

−3/2u=15

Step 2: Multiply both sides by 2/(-3).

(2−3)*(−32u)=(−3)*(15)

u=−10
