Answer:
y = -4
Step-by-step explanation:
-8y+6(y+5) = 38
-8y + 6y + 30 = 38
-2y + 30 = 38
-2y = 8
8 / -2 = -4
y = -4
Answer:
V= -4
Step-by-step explanation:
-8v+6(v+5) = 38
-8v+6v+30 = 38
-2v = 38-30
-2v = 8
v = 8/-2
v = -4

Answer:
x = - 2 2/3
y = - 4 1/3
Step-by-step explanation:
-4x -2y = - 2
4x +8y = -24
Now if you just add those 2 equations, what will happen is that the xs will cancel. They are equal but opposite in sign
6y = - 26 Now divide by 6
6y/6 = -26/6 Combine
y = - 4 2/6 = - 4 2/6
y = - 4 1/3
Now use the top equation to find x
-4x - 2(-4 1/3) = - 2
-4x + 8 2/3 = - 2 Subtract 8 2/3 from both sides
- 4x = - 2 - 8 2/3 Combine
- 4x = - 10 2/3 Divide by - 4
x = - 10 2/3 / - 4
x = - 2 2/3

Answer:
(x, y) = (8/3, -13/3)
Step-by-step explanation:
The x-coefficients are opposites, so the x-terms can be eliminated simply by adding the equations.
(-4x -2y) +(4x +8y) = (-2) +(-24)
6y = -26
y = -26/6 = -13/3
Substituting into the first equation gives ...
-4x -2(-13/3) = -2
2x -13/3 = 1 . . . . . . . . divide by -2
2x = 16/3 . . . . . . . . . add 13/3
x = 8/3
The solution is (x, y) = (8/3, -13/3).

If Enguun tutored for 19.5 hours last month, how much money did she earn last month?
share out £20 between bill and sue in the ratio 3:2
Answer:
12:8
Step-by-step explanation:
Bill receives £12, and Sue receives £8.
In order to divide £20 between Bill and Sue in the ratio 3:2, we first need to find the total number of parts in the ratio. The sum of the parts in a 3:2 ratio is 3 + 2 = 5.
Next, we determine the value of one part by dividing the total amount (£20) by the total number of parts (5): £20 ÷ 5 = £4.
Now, we can allocate the money to Bill and Sue according to their shares in the ratio. For Bill, who gets 3 parts, we multiply his share of one part (£4) by 3: £4 × 3 = £12. For Sue, who gets 2 parts, we multiply her share of one part (£4) by 2: £4 × 2 = £8.
Thus, Bill receives £12, and Sue receives £8.
In mathematical terms, we can represent the division of £20 between Bill (B) and Sue (S) as follows:
Let the ratio be represented as B:S = 3:2.
Total parts in the ratio = 3 + 2 = 5.
Value of one part (Vp) = Total amount / Total parts = £20 ÷ 5 = £4.
Amount received by Bill (Ab) = 3 parts × Vp = 3 × £4 = £12.
Amount received by Sue (As) = 2 parts × Vp = 2 × £4 = £8.
Thus, Bill receives £12, and Sue receives £8.
In summary, when dividing £20 between Bill and Sue in the ratio 3:2, we follow the steps of finding the total parts in the ratio, calculating the value of one part, and then distributing the amount based on each individual's share in the ratio.

In the equation cd = -56, find the value of d if c = 4.
Answer:
-14
Step-by-step explanation:
CD= -56
C=4
D= CD/C
= -56/4
= -14
Hello there!
cd=-56.
We are given that
c=4
We can plug it into the equation instead of c:
4d=-56
Now we must divide both sides by 4 in order to isolate d:
d=-14
Remember that whatever we do to one side, we do to the other.
