Answer:
B) -x+8y=56
Step-by-step explanation:
y=1/8x+7
Multiply by 8 to clear the fraction
8y = 8(1/8x+7)
Distribute
8y = 8*1/8x +8*7
8y = x+56
Subtract x from each side
-x+8y = x-x+56
-x+8y = 56
Answer: 32:1
Step-by-step explanation: Every hour she/he does 32 problems, so therefore the ratio is 32:1.
Answer:
12.41 minutes.
Step-by-step explanation:
It is given in the question that a plane can fly 725 miles per hour.
So, the plane goes 725 miles in 1 hour i.e. 60 minutes.
Now, we have to find the time the plane takes to fly 150 miles.
As the plane is flying at a constant rate, so we can use the unitary method to get the required time.
Therefore, the plane will take
minutes to fly 150 miles. (Answer)
Answer:
6.75>6.732
Step-by-step explanation:
We are given that
6.75 and 6.732
We have to compare two given decimal numbers.
First we convert like decimal number
In 6.75 there are two digits after decimal point.
In 6.732 , there are three digits after decimal point
Therefore, we put zero in 6.75 to convert like decimal number
Now, we get
6.750
Unit place of both decimal numbers are same and tenth place of both decimal number are same.
Now, hundredth place of 6.750 is 5 and hundredth place of 6.732 is 3
5 >3
Therefore, 6.750 is greater than 6.732
6.75>6.732
