Hi there! The answer is 30 hours.
Let the number of worked hours be represented by X.
The total earn of option 1, would then be 10X + 60
The total earn of option 2, would then be 12X
We end up with the following equation:

Subtract 10X from both sides.

Divide both sides by 2.

Therefore, after 30 hours of work Rebecca will earn the same amount of money.
Answer:
option A) Agree, because the solutions are the same is correct.
Step-by-step explanation:
FIRST SYSTEM


solving the system



adding the equation




so the system becomes

solve -5y for y

Divide both sides by -5

simplify



subtract 16/5 from both sides


Divide both sides by 6


Therefore, the solution to the FIRST SYSTEM is:

SECOND SYSTEM


solving the system







so the system of equations becomes

solve -5y for y

Divide both sides by -5

Simplify




Divide both sides by 2

Simplify

Therefore, the solution to the SECOND SYSTEM is:

Conclusion:
As both systems of equations have the same solution.
Therefore, we conclude that Albert is right when says that the two systems of equations shown have the same solutions.
Hence, option A) Agree, because the solutions are the same is correct.
Answer:
x = 19
Step-by-step explanation:
YZ || XW, so ∠Y = ∠W
if ∠Y = ∠W, then ∠W = 2x
since the sum of the angles of a triangle is 180 degrees:
(3x-5) + 2x + 90 = 180
x = 19
So 5 and 1/2 cup flour =1 and 9/16
multiply both sides by 16
80 and 16/2 cups=16 and 9
88 cups=25 pounds
divide by 5
88/5=5 pounds
multiply by 2
176/5=10 pounds
176/5=35 and 1/5
35 and 1/5 cups=10 pounds
there is MORE than 35 cups of flour in a 10 pound bag
Answer:
$56.00
Step-by-step explanation:
35+(60/100)
=21
35+21
=$56.00
