Answer:

Step-by-step explanation:

So for this we will be using a system of equations, with one equation representing Shakira's sales and the other representing Jeff's sales. Our equations are such (Let x = oranges and y = grapefruit)

For this, I will be using the elimination method. So firstly, multiply both sides of the second equation by -4: 
Next, add 5x+8y=235 and -12x-8y=-340 to get -7x = -105 . From here we can solve for x.
For this, just divide both sides by -7, and your answer is going to be x = 15.
Now that we know what x is, just substitute x for 15 in either equation to solve for y. For this I will be using the second equation.

Since we know that oranges cost $15 and grapefruit cost $20, just add them together to get your answer, which is $35.
Answer:
7.25
Step-by-step explanation:
10,9.75,9.5,9.25,
the rest of the sequence would look like
8, 7.75, 7.5, 7.25, 7, 6.75, 6.5, 6.25, 6 etc.
(the pattern is - .25 from the previous number.
so the 8th number in this sequence is 7.25
hope this helps!!:)
Answer:
The simplified ratio would be 8 to 5.
Step-by-step explanation:
We can get the simplified ratio by finding the largest number that both sides can be divided by. In this context, it is the number 3 so we divide both sides by 3 to simplify the ratio.
Answer: 56 mph
Step-by-step explanation:
48 miles x 2 hours = 96 miles
60 miles x 4 hours = 240 miles
240 + 96 = 360 total miles
360 / 6 (hours) = 56 mph
