GrandD is < or = to 5 GrandS is greater or = to 7

Step-by-step explanation:

These are so fun!

Let GrandD = X

Let GrandS = X + 2 (because he is two years older than GrandD)

Their age together is 12 years - so...

GrandD + GrandS = 12 OR...

x + x + 2 = 12

Now solve for x.

2x + 2 = 12

2x = 10 (because we subtract the ones on the left from the ones on the right)

x = 5 (because we divide both sides by 2)

This means that GrandD (x) is equal or greater than 5 years old

And GrandS (x + 2) = or greater than 7 years old

Fast-Food Delight is open

LekaFEV [45]

Answer:

10.30p.m - 6.00a.m = 4.30

11.00p.m - 6.00a.m = 5.00

11.00p.m - 7.00a.m = 4.00

4.30 + 5.00 + 4.00 = 13.30

or you could do

4.30 + 4.00 = 8.30

8.30 + 5.00 = 13.30

13.30 = 1.30

I don't know if this is right, but i tried my best to help.

The food bank has 1774.4 oz of chicken.If 12.6 oz is 2 servings,how many servings of chicken does this provide?

diamong [38]

Answer:

281 servings

Step-by-step explanation:

From the table attached,

We will apply the unitary method to solve this problem.

∵ 12.6 oz of chicken represents number of servings = 2

∴ 1 oz of chicken will represents number of servings = $\frac{2}{12.6}$

∴ 1774.4 oz of chicken will make the total servings = $\frac{2}{12.6}\times 1774.4$

= 281.65

≈ 281 servings

Therefore, total number of servings provided = 281

Jason's business computers need servicing. The expression 81x + 108 represents a contractor's total charges in dollars for fixin

kolbaska11 [484]

Answer:

2 hours

Step-by-step explanation:

Given

$Contractor: 81x + 108$

$Electronic\ Store: 103x + 64$

Required

Determine the hours when the charges are the same

To do this, we simply equate both expressions:

$Contractor = Electronic\ Store$

$81x + 108 = 103x + 64$

Collect Like Terms

$81x - 103x = 64 - 108$

$-22x = -44$

Divide both sides by -22

$x =2$
