Answer: (10, -2)
That is, x = 10, y = -2
Step-by-step explanation: Let 3x + 2y = 11 be equation I
Let x -2 = -4y be equation II
We shall use the substitution method like stated above.
From equation II, add 2 to both sides
x = 2 - 4y
Next, substitute for the value of x into equation I
3x + 2y = 11
3(2 - 4y) + 2y = 11
6 - 12y + 2y = 11
6 - 10y = 11
Subtract 6 from both sides of the equation
-10y = 5
Divide both sides of the equation by 5
-2 = y
Next, substitute for the value of y (-2) into equation II
x - 2 = -4(-2)
x - 2 = 8
Add 2 to both sides of the equation
x = 10
Therefore the solution is, (10, -2)
Answer:
The sum of 68 and 14 = 82
The product of 56 and 65 = 3640
The difference between 78 and 24 = 54
The quotient of 648 and 13 = 49.84
65 multiplied by 45 = 2925
Find the quotient of 230 and 5, then add 47 = 93
Subtract 43 and 12, then divide by 3 = 10.33
Find the product of 681 and 23, then subtract by 4 = 15659
Add 9 to the difference of 19 and 8 = 20
Multiply the sum of 87 and 16 by 13 = 1339
Subtract 56 from the product of 58 and 42 = 2380
Add 99 to the quotient of 850 and 10 = 184
Answer:
Answer = 235.5
Step-by-step explanation:
Cone volume formula is V = 1/3 * pi * r^2 * h
V = 1/3 * 3.14 * 5^2 * 9
V = 235.5
