Answer:
y = sqrt(29)/2 - 1/2 or y = -1/2 - sqrt(29)/2
Step-by-step explanation:
Solve for y:
y^2 + y - 7 = 0
Add 7 to both sides:
y^2 + y = 7
Add 1/4 to both sides:
y^2 + y + 1/4 = 29/4
Write the left hand side as a square:
(y + 1/2)^2 = 29/4
Take the square root of both sides:
y + 1/2 = sqrt(29)/2 or y + 1/2 = -sqrt(29)/2
Subtract 1/2 from both sides:
y = sqrt(29)/2 - 1/2 or y + 1/2 = -sqrt(29)/2
Subtract 1/2 from both sides:
Answer: y = sqrt(29)/2 - 1/2 or y = -1/2 - sqrt(29)/2
The answer is 20 because 4x2 is your 8 oz so 10x2 will give you 20oz
Answer:
x = 32
Step-by-step explanation:
Given the following data;
Unknown number = x
Translating the word problem into an algebraic equation, we have;
Lowest common denominator (LCD) = 2
We multiply all through by 2;
x = 32
Therefore, the unknown number is 32.
Answer:
Total money earned = £1,947.35
Step-by-step explanation:
Given:
Per ticket cost = £3.95
Number of rows = 17
Number of seats in each row = 29 seats
Find:
Total money earned.
Computation:
Total number of seats = Number of rows × Number of seats in each row
Total number of seats = 17 × 29
Total number of seats = 493 seats
Total money earned = Total number of seats × Per ticket cost
Total money earned = 493 × £3.95
Total money earned = £1,947.35
