A party rental company has chairs and tables for rent. The total cost to rent
Paha777 [63]

Let c= cost to rent each other

Let t= cost to rent each other

2c+3t=25

6T+5T=49

Multiply the 2nd equation by (-2) and add equation together  

2c+3t=25

-12c-10t= 98

2t=98

T=49

Put this value into the 1st equation solve c

2c+3(49)=49

2c+147=49

2c=98

C=49

Cost to each chair and table are same 49.

Rob ran 27.2 miles less than Jasmine last week. Rob ran 10 miles. How many miles did Jasmine run?
jeka94

Answer:

Jasmine ran last week 37.2 miles

Step-by-step explanation:

Let

x ----> number of miles Rob ran last week

y ----> number of miles Jasmine ran last week

we know that

x=y-27.2 ----> equation A

x=10 ----> equation B

Substitute equation B in equation A and solve for y

10=y-27.2

y=10+27.2

y=37.2 miles
