Answer:
The answer is 25.
Step-by-step explanation:
First, you solve 6+x=13. Minus 6 from each side. You get x=7.
Next, plug x into the equation 8x-31. You get 8(7)-31. Solve 56-31, which you then get 25.

A painter mixes cans of green and white paint to make the shade needed for painting a bedroom. The table shows the
ratios he can use for the color he wants.
Green cans (g) 6 10 16 18
White cans (W) 915 24 27
Which is a direct variation equation for this relationship?
Answer:
A. 2/3w
Step-by-step explanation:
Option A is correct, g = 2/3 w is a direct variation equation for the given relationship
To determine the direct variation equation, we need to check if the ratio of green cans (g) to white cans (w) is constant across all the given ratios.
Let's calculate the ratios for each case:
For the first ratio: g = 6 and w = 9
g/w = 6/9
= 2/3
For the second ratio: g = 10 and w = 15
g/w = 10/15
= 2/3
For the third ratio: g = 16 and w = 24
g/w = 16/24
= 2/3
For the fourth ratio: g = 18 and w = 27
g/w = 18/27
= 2/3
Since the ratio of g/w is the same (2/3) for all cases, we can see that the relationship between green cans (g) and white cans (w) is a direct variation
Hence, the direct variation equation is g = 2/3 w, option A is correct.

George deposits $3,500 at 3.25% interest compounded monthly. What will his ending balance be after 5 years?
Answer:
FV= $4,117.1
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $3,500
Number of periods= 5*12= 60 months
Interest rate (i)= 0.0325/12= 0.00271
To calculate the Future Value, we need to use the following formula:
FV=PV*(1+i)^n
FV= 3,500*1.00271^60
FV= $4,117.1

At a cherry farm, the cost per pound of cherries depends on the amount of cherries bought. For an amount up to 100 pounds, the cost is $1.75 per pound, and, for an amount over 100 pounds, the cost is $1.50 per pound. Ralph bought 60 pounds and Jeff bought 80 pounds separately. If they had bought the total amount jointly, how much would they have saved?
Answer:
they would have saved 35 dollars

Describe the nature of the roots for the equation 49x^2-
28x +4 = 0
O one real root
one complex root
O two complex roots
O two real roots
Answer:
Step-by-step explanation:
One real root
The nature of the roots of [tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex] is (a) one real root
The equation is given as:
[tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex]
To determine the nature of the roots, we make use of determinants.
The determinant (d) of a quadratic equation is calculated
[tex]\mathbf{d = b^2 - 4ac}[/tex]
Where the quadratic equation is:
[tex]\mathbf{ax^2 + bx + c = 0}[/tex]
By comparison, we have:
[tex]\mathbf{a = 49,\ b = -28,\ c = 4}[/tex]
So, we have:
[tex]\mathbf{d = b^2 - 4ac}[/tex]
[tex]\mathbf{d = (-28)^2 - 4 \times 49 \times 4}[/tex]
[tex]\mathbf{d = 784 - 784}[/tex]
[tex]\mathbf{d = 0}[/tex]
When d = 0, then the function has one real root.
Hence, the nature of the roots of [tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex] is (a) one real root

Have 1 case of 2 rocks, and 4 cases of 11 rocks.
Answer:. B. Have 9 cases of 2 rocks, and 4 cases of 11 rocks
Step-by-step explanation:
Total rocks = 62
A. Have 4 cases of 2 rocks, and 9 cases of 11 rocks
(4 * 2) + (9 * 11) > 62 ( false)
B. Have 9 cases of 2 rocks, and 4 cases of 11 rocks
(9 * 2) + (4 * 11) = 18 + 44 = 62 rocks (true)
C. Have 9 cases of 2 rocks, and 1 case of 11 rocks
(9 * 2). + (1 * 11) < 62 ( false)
D. Have 1 case of 2 rocks, and 4 cases of 11 rocks.
(1 * 2) + (4 * 11) < 62
