Answer:
3a) 5/45 you divide by 5
3b) 6/7 you divide by 2
3c) 2/7 you divide by 9
3d) 2/5 you divide by 9
4a) 6
4b) 1 <u>1/4</u> or 5/4 (both are correct)
4c) 3 <u>1/2</u> or 3 <u>3/6</u> (both are correct)
4d) 5 <u>1/8</u>
The fraction bar tells you to divide the top number by the bottom number.
Step-by-step explanation:
For 3a through 3d, you just use the fraction that has a missing number, and if the missing number is at the bottom, use the top number and devide it by the other top number that the fraection is equal to.
For 4a through 4b, devide the top the bottom number
X = amount of lawns
y = amount of dog walks
25x + 15y = 1975
25x + 15(50) = 1975
25x + 750 = 1975
25x = 1225
x = 49
so x ≤ 49 (this number depends on how much Sarah walks)
y ≥ 50 (is how much Sarah walks)

The first thing we must do for this case is to define variables.
We have then:
x: number of slices
y: total cost
We write the linear function that relates the variables.
We have then:
Then, we evaluate the number of slices to find the total cost.
-two slices cost:
We substitute x = 2 in the given equation:
Answer:
two slices = 2.2 $
-ten slices cost:
We substitute x = 10 in the given equation:
Answer:
ten slices = 11 $
-half a slice cost:
We substitute x = 1/2 in the given equation:
Answer:
half a slice = 0.55 $
The largest arch for this case is the ADB arch.
To know the size of the major arc, the first thing you should keep in mind is that the entire circumference measures 360 degrees.
We then have the following equation:
ADB + 50 = 360
From here, we clear the value of ADB.
We have then:
ADB = 360 - 50
ADB = 310 degrees.
Answer:
The measure of the major arc is:
ADB = 310 degrees.
