Question:
Katy makes 48 cookies an hour. If she has 24 already, how long would it take her to make 120?
Answer:
It takes 2.5 hours for Katy to make 120 cookies
Step-by-step explanation:
Given:
Time taken to make 48 cookies = 1 hour
To Find:
Time taken to make 120 cookies = ?
Solution:
Time taken to make 48 cookies = i hour
So now time taken to make 1 cookie = 
So time taken to make 120 cookies
= Number of cookies X time taken to make one cookie
=>
=>
=> 2.5 hours
Answer:
y = 7x - 13
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 7x - 8 ← is in slope- intercept form
with slope m = 7
Parallel lines have equal slopes, thus
y = 7x + c ← is the partial equation
To find c substitute (5, 22) into the partial equation
22 = 35 + c ⇒ c = 22 - 35 = - 13
y = 7x - 13 ← equation of parallel line
Answer:
slope means the monthly salary is $425
Step-by-step explanation:
4050 - 3200 / 6 - 4 = 850 / 2 which is same as 425 / 1
4475 - 4050 / 7 - 6 = 425 / 1
4900 - 4475 / 8 - 7 = 425 / 1
A formula or equation which specifies how the y is obtained when x is given
Answer:
m=(-6,6)
Step-by-step explanation:
m^2 -36 = 0
Reorder the terms:
-36 + m^2 = 0
Solving for variable 'm'.
Add '36' to each side of the equation.
-36 + 36 + m^2 = 0 + 36
Combine like terms: -36 + 36 = 0
0 + m^2 = 0 + 36
m^2 = 0 + 36
Combine like terms: 0 + 36 = 36
m^2 = 36
Simplifying
m^2 = 36
Take the square root of each side:
√m^2=+/-√36
m=(+/-)6
m = {-6, 6}
