Answer:
54 cookies
Step-by-step explanation:
seven dozen means 7 * 12 cookies
because one dozen = 12 cookies, so having seven dozen means have seven, one dozen batches
seven dozen = 7*12 = 84 cookies
she already made 138
138 - 84 cookies = 54 cookies left to go
54 cookies
Answer:
4.5 hours
Step-by-step explanation:
Assume the relation between points is a linear relation.
Use the given information as points in a linear equation.
Find the equation of the line; then find x when y = 25.75.
Find the equation of the line that passes through points (3, 23.5) and (8, 31).
y = mx + b
m = (y2 - y1)/(x2 - x1) = (31 - 23.5)/(8 - 3) = 7.5/5 = 1.5
y = 1.5x + b
Use point (8, 31) as x and y, and solve for b.
31 = 1.5(8) + b
31 = 12 + b
b = 19
The equation is
y = 1.5x + 19
Now let y = 25.75, and solve for x.
y = 1.5x + 19
25.75 = 1.5x + 19
6.75 = 1.5x
x = 4.5

Answer and Step-by-step explanation:
The answer is <u>A. 67.5.</u>
We are told the scale factor of a model train is 1 inch to 13.5 feet.
We multiply the 5 inch model car by 13.5 to get the car size.
<u>5 times 13.5 is 67.5.</u>

Answer:
y = -2/3x + 1
Step-by-step explanation:
We already know the slope, so all we need to do is find the y-intercept. To find that, we need to plug the coordinates into the equation so far, which is,
y = -2/3x + b
1 = -2/3(0) + b
1 = 0 +b
1 = b
So the equation is y = -2/3x + 1
