UGH! RSM!!!!!!!!!!!!!!!!!!!!! John's family visited his grandmother over the weekend. The drive to her house took 2 hours at their usual speed. the trip home took 15 minutes longer because traffic was bad and they had to drive 5 mph slower. How many miles away is john's grandmother's house? will give BRAINLIEST! +10pts!

Answers

(1)- 30
Hope this helps!

Answer:

90 miles!

Step-by-step explanation:

there are two parts to the problem, meaning you'll need 2 equations.

let's call the distance TO the grandma's house d1, and BACK from the grandma's house d2.

KEY:

time TO g'ma house= t1

time FROM g'ma house=t2

(replace the t's with 's' for speed, with the '1' for to, and '2' for from)

(distance is a constant so d1 is always equal to d2).

-------------

d1=s1+t1, d2=s2+t2

we know what t1 is. 2 hours.

d1=s1•2

meaning that d2 is also equal to that.

s1•2=(s1-5)•2 1/4

2s1=2 1/4 s1-11 1/4

11 1/4= 2 1/4 s1-2s1

11 1/4 = 1/4 s1

s1 (to g'ma)=45 mph

distance is speed times time.

so 45•2 (hr) = 90.

Answer:

is this a test

Step-by-step explanation:

Answer:

1. No Solution, 2. Unique Solution, 3. Infinitely Many Solutions

Step-by-step explanation:

1. If two lines are parallel, they share no common points, and no answers.

2. y = 3x + 4 and y = 1/2x + 5 are not parallel and not equivalent, therefore, they have one solution.

3. Simplified, the two equations are z + 2y = 10 and z + 2y = 10, therefore they are equivalent and they have solutions for as far as the line extends, which is infinitely.

The Wagner school store is having a sale! At the sale this week, a life sized stuffed animal of Wagner’s mascot is being sold for $158.40. This is a 52% discount of the original price. What is the original price? If necessary, round to the nearest cent.

Answers

Divide the sale price by the percentage of the original cost.

Percent of original cost = 100% - 52% = 48 %

158.40 / 0.48 = 330.00

The original price was $330.00

Mimi bought some fabric for a sewing project. The fabric cost $15.40 per meter. She bought 250 centimeters of fabric.

How much did Mimi pay for the fabric?

Answers

Answer:

$38.50

Step-by-step explanation:

so there are a hundred centimetres in a meter so u have to divide the 250 by 100

250 / 100 = 2.5 meters

and its 15.40 for 1 meter and she bought 2.5 so multiply those

15.40 * 2.5 = 38.50

she paid $38.50 for 2.5 meters of fabric

Answer:

$38.50

Step-by-step explanation:

There are 100 centimetres in a meter. If Mimi bought 250 centimetres of fabric, that is 2.5 meter. So then we do 2.5 x 15.40 = 38.50. Make sure you add the $ sign!
