Answer:
x=4 and y=1
Step-by-step explanation:
Equation 1) 3x+8y=20
Equation 2) 5x+3y=23
Equation 1) 5(3x+8y=20 )
Equation 2) 3(5x+3y=23)
15x+40y=100
15x+9y=69
(Take away 40y from 9y and 100 from 69)
31y = 31
y=1
Substitute y=1 into equation 1)
3x+8=20
(Take away 8 from both sides)
3x=12
(Divide by 3)
x=4
Answer:
3/10
Step-by-step explanation:
If both halves were equal.
½ × ½ = ¼
Closest option is 3/10
4x-3=5y
it would be : 4x - 5y = 3
Here, the answer would be: 765 * 11 = 8415 [ About 8 thousands ]
In short, Your Answer would be Option C) <span>The answer should be about 8,000 yards. The student's answer is not correct.

The future value of cash whose initial value is $845, at the rate of 11.3% for 7 years will be calculated using the compound interest rate, that is:
A=p(1+r/100)^n
where:
A=future amount
r=rate=11.3%=0.113
time=7 years
thus the future value of our cash will be:
A=845(1+0.113)^7
A=845(1.113)^7
A=$1,787.82
