Answer:
Step-by-step explanation:
To add fractions you need equal denominators
7/100+(1/10)(10/10)
7/100+10/100
17/100 (or 0.17 as a decimal)
Answer:
1/8, 1/4, 3/8, 9/16, 3/4, 1
Step-by-step explanation:
y varies inversely with x.
Example:
If we multiply x by 2 we need to divide y by 2 too.
So,
If y = 16 and x = 1/2, find y when x = 32
Lets see, from 1/2 to 32 e need to multiply 1/2 by 64, right? So let's divide 16 by 64.
16/64 = 8/32 = 4/16 = 2/8 = 1/4
So we can say that:
If y = 16 when x = 1/2, y = 1/4 when x = 32.
They would be riding in the train for 8 hours and in the car for 5 hours.
They spent 560 miles on the train
They spent 200 miles in the car
Answer:
A. Infinitely many solutions.
Step-by-step explanation:
The row and column numbers are equal in the echelon. This rows have 0001 numbers which indicates that there is free variable at the end. The reduced row echelon has equal number of rows and columns. There are infinitely many solution as the numbers in the rows are zero ending of the free variable 1. If there is no free variable then there will be no solution.
