Part A) First, you need to find out how much she makes each hour.40/5 = 8 & 48/6 = 8 ... This shows that she makes $8 an hour
To find the first missing number, you will do 8 * 8 = 64 ... This shows that she makes $64 in 8 hours.
To find the second missing number, you will do 56/8 = 7 ... This shows that she makes $56 in 7 hours.
Part B) Barb makes $9 every hour. To find the amount of money she earns for 5, 6, and 8 hours of work you will need to multiply $9 by the amount of hours she worked.
9 * 5 = 45 ... This shows that she makes $45 in 5 hours.
9 * 6 = 54 ... This shows that she makes $54 in 6 hours.
9 * 8 = 72 ... This shows that she makes $72 in 8 hours.
Part C) In part B, you found out how much she makes after working at the theme park for 5 hours. ($45 in 5 hours)
Next, you'll need to find out how much she makes after mowing lawns for 5 hours.
5*8 = $40 ... This shows that she makes $40 in 8 hours
Now you need to the difference. 45 - 40 = 5 ... She makes 5 more dollars working at the theme park for 5 hours than mowing lawns for 5 hours.
Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.
Answer:
12
Step-by-step explanation:
4:1:1, from the ratio, you know that there are 6 in total (4+1+1)
so set up a proportion
(4/6) = (48/x)
so... (6 x 48) / 4 = x
x = 72, the total
now repeat to find the value for Pip
(1/6) = (x/72)
72 / 6 = 12
Answer: i don't know you have to figure it out yourself duh.
Step-by-step explanation: This is none of your beeswax
A.
= (x + 2)^2 - 4 - 11
= (x + 2)^2 - 15
B. vertex is at ( -2, -15) which is a minimum because the coefficient of x^2 is positive.
C. The axis of symmetry is a vertical line passing through the vertex It is
x = -2.
