Answer:
Step-by-step explanation:
Given
Cost of 4 lb orange = $3.92
Cost of 40 lb orange = $39.20
Required
Determine the proportion
The proportion can be calculated susing:
<em>Where k = proportion</em>
Make k the subject:
When y = 3.92 and x = 4
The proportion (k) is calculated as thus:
When y = 39.2 and x = 40
Using the same formula:
Substitute 0.98 for k in
Hence, the proportional relationship is
The answer is three, 150 square feet
Answer:
x= -674
Step-by-step explanation:
Solve for x and check: x + 5 = 3
Solution
Solve for x and check: - 3x = 12
Dividing each side by -3, we obtain
Another way of solving the equation
3x - 4 = 7x + 8
would be to first subtract 3x from both sides obtaining
-4 = 4x + 8,
then subtract 8 from both sides and get
-12 = 4x.
Now divide both sides by 4 obtaining
- 3 = x or x = - 3
Solve for c: 3(x + c) - 4y = 2x - 5c
First remove parentheses.
Remember, abx is the same as 1abx.
We divide by the coefficient of x, which in this case is ab.
Yes. 40 is one tenth of 400
The answer is A
1 5/6 *12= 22
