Answer:

option C 2*x + 3*y = 7.20

4 *x + 2*y = 8.80

1.4

Step-by-step explanation:

PART A

Steve

2lbs of grapefruit

3lbs oranges for $7.20

kennedy

4lb grapefruit

2lb oranges for $8.80

price 1 pound grapefruit x

1 pound oranges y

Then for steve

2*x + 3*y = 7.20

for kennedy

4 *x + 2*y = 8.80

PART B

now we have to find y from above equations

2x + 3y = 7.20   multiply by 2 on both sides 4x + 6y = 14.4

4x + 2y = 8.80

next by substracting the above two equations we get

6y - 2y = 14.4 - 8.80

4y = 5.6

y = 1.4

Answer: Choice B) (24,10)

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

Work Shown:

2x - 4y = 8
2( x ) - 4y = 8
2( 3y-6 ) - 4y = 8 ... notice x has been replaced with 3y-6
2(3y)+2(-6) - 4y = 8
6y-12 - 4y = 8
2y-12 = 8
2y-12+12 = 8+12 ... add 12 to both sides
2y = 20
2y/2 = 20/2 ... divide both sides by 2
y = 10

If y = 10, then
x = 3y-6
x = 3*10-6 ... replace y with 10
x = 30-6
x = 24

Put together, the solution is (x,y) = (24,10)
which is why the answer is choice B

As a check, we can plug (x,y) = (24,10) into each equation
x = 3y-6
24 = 3*10 - 6
24 = 30 - 6
24 = 24 ... true equation
and similarly for the second equation as well
2x-4y = 8
2*24 - 4*10 = 8
48 - 40 = 8
8 = 8 ... true equation
Both equations are true when (x,y) = (24,10) so the solution is confirmed

Jacoby followed a recipe that requires 2 cup for water four every 3 cups of flours. if he used 8 cups flours, how many cups of w
zmey [24]

Answer:

5 and 1/3 cups of water.

Step-by-step explanation:

Set up a proportion like this:

  2:3 for the original recipe

Then a second proportion for the recipe Jacoby used:  

  w:8  (use w for the unknown water amount)

Set up an equation so that the proportions equal each other. It helps if you write them in fraction form:

  \frac{2}{3} =\frac{w}{8}

Use cross multiplication to get the new equation:

  8 x 2 (or 16) = 3w

Then, divide both sides by 3 to get the amount for w, or water, by itself:

5 and 1/3 = w

I hope this helps! ☺

A bank manager wants to encourage new customers to open accounts with principals of at least $3,000. He decides to make a poster
ankoles [38]

Assuming that the 4.8% interest rate is an annual interest rate, then, after one year, with a principal of $3,000 we would be able to win 4.8% of $3000:

3000\times\frac{4.8}{100}=144

Divide 144 over 12 to find the monthly earnings:

\frac{144}{12}=12

Therefore, with a principal of $3,000 we would be earning $12 interest in 1 month.

For the earnings on the first month to be equal to $10, then you would have to win $120 annually, and $120 must be 4.8% of the principal. To find which quantity satisfies that 4.8% of it is equal to $120, divide 120 over 4.8%:

\frac{120}{4.8\text{ \%}}=\frac{120}{(4.8/100)}=\frac{100}{4.8}\times120=2500

Therefore, the principal must be equal to $2500 for you to win $10 on the first month, and it would indeed be correct to say that if you open an account with $3000 you will earn at least $10 interest in 1 month.
