Answer:
y = 95
Step-by-step explanation:
x + 120 = 180
25 + x + y = 180
flipping the first equation 180 - 120 = 60 so x is 60.
so plug in 60 into the second equation
25 + 60 + y =180 --> 85 + y =180 flip equation 180 - 85 = 95
so y is 95
It should be the first one
Hey there! I'm happy to help!
Let's represent the number of days with x.
WAREHOUSE A
200-15x
WAREHOUSE B
80+25x
We want to find how many days it will take for the two warehouses to have the same amount of coal. Let's put these expressions into an equation to show that they are equal and see what x is.
200-15x=80+25x
We subtract 25x from both sides.
200-40x=80
We subtract 200 from both sides.
-40x=-120
We divide both sides by -40
x=3
Therefore, warehouse A and warehouse B will have the same amount of coal after 3 days.
Have a wonderful day! :D
Answer:
Step-by-step explanation:
Let's first look at the coefficients: 10, -15, 20
The GCF of these numbers is 5 (all numbers are divisible by 5, nothing larger).
Next, let's look at the terms:
The GCF of these terms is (find the lowest exponent)
Finally, let's look at the terms:
The GCF of these terms is (find the lowest exponent)
This gives us a GCF of
