14(y) = 70
y = 70/14
y = 5
hope this helps
Answer:
a. 12
b. 8006
Step-by-step explanation:
We have company A, which is determined with the following equation:
A = 6500 + 125.5 * x
where x is the amount of ton of sugar
Same for company B:
B = 5597 + 200.7 * x
We want to know when A = B are equal, therefore:
6500 + 125.5 * x = 5597 + 200.7 * x
200.75 * x - 125.5 * x = 6500 - 5597
75.25 * x = 903
x = 903 / 75.25
x = 12
That is to say that when they are 12 tons of sugar they charge the same.
To know how much the value would be:
A = 6500 + 125.5 * 12 = 8006
B = 5597 + 200.75 * 12 = 8006
That is to say that the value when it is equal is 8006
T = 1/5(x - y + z)
First, let's get rid of the 1/5. To do this, you can multiply both sides by the reciprocal, or 5/1.
(5/1)T=[(5/1)1/5](x-y+z)
5T = x - y + z
Now subtract x from both sides.
5T - x = -y + z
Add y to both sides.
5T - x + y = z
So the answer is:
z = 5T - x + y
Answer:
<h2><u><em>
5 and 7</em></u></h2>
Step-by-step explanation:
One number is 2 more than another. The difference between their squares is 24. What are the numbers?
(x + 2)² - x² = 24
x² + 4x + 4 - x² = 24
4x + 4 = 24
4x = 20
x = 20 : 4
x = 5
----------------------
5 + 2 = 7
check
(5 + 2)² - 5² = 24
49 - 25 = 24
24 = 24
the answer is good
