Answer:
x = -2
y = 8
Step-by-step explanation:
8x + 5y = 24
y = -4x
8x + 5 (-4x) = 24 (Substitute y value)
8x - 20x = 24 (Multiply)
-12x = 24 (Combine like terms and divide)
x = -2
y = -4 (-2) (Substitute x value. Multiply)
y = 8

What do you need help with
Step-by-step explanation:
First, you recognize the algorithm for the equation: A=P(1+r)^n. This is the algorithm for interest. P is the amount of initial money (in this case, 6500), r is the interest rate (6%, or 0.06), and n is the number of times it is being compounded. Since half a year is given to me, 6 months is what I will be using, or just 6.
Next, plug in the numbers. The equation is now: A=6500(1+0.06)^6.
Now time to solve. First add what's in the parenthesis, and put it to the power of 6, for 6 months. Then multiply that amount to the initial dollar amount; 6500. This will leave you with 9,220.37.
Answer: t = $5.82·b÷3✔️
Step-by-step explanation:
We have to divide the cost of three oranges ($ 5.82) by 3 to calculate the cost of one orange, then we have to multiply by the number of oranges (b).
<h3>Example: </h3>
Cost of three oranges: t = $5.82·3÷3 = $5.82
