Step-by-step explanation:

-  \frac{4}{5}  + y =  -  \frac{1}{4}  \\ y =  \frac{ - 1}{4}  +  \frac{4}{5}  \\ y =  \frac{ - 5 + 16}{20}  \\ y =  \frac{11}{20}

y =  \frac{11}{20}

Answer:

y = 11/20

Step-by-step explanation:

-4/5 + y = -1/4

Add 4/5 to each side

-4/5  +4/5 + y = -1/4+4/5

y = -1/4 + 4/5

Get a common denominator

y = -1/4 *5/5   + 4/5 *4/4

y = -5/20 + 16/20

y = 11/20

Check

-4/5 +11/20 = -1/4

Get a common denominator

-4/5*4/4 + 11/20 = -1/4*5/5

-16/20 +11/20 = -5/20

-5/20 = - 5/20

Check

PLEASE HELP DON’T ANSWER IF YOU DON’T KNOW!! Mr. Sanchez drives 120 miles in 3 hours. At the same rate, how far will he drive
anygoal [31]

Answer:

200 miles

Step-by-step explanation:

First have to find how many miles he drives in 1 hour. So, we divide 120 miles by 3 hours, since we assume that he managed to drive an equal amount in each hour.

120/3=40

This shows that Mr. Sanchez drove at a rate of 40 mph.

But, this isn't the answer. 40 miles is the distance for one hour of driving. To find the distance for 5 hours, we have to multiply the distance by 5 as well.

40 times 5=200
