Richard is planning a banquet for the wrestling
team. A restaurant charges $22 per person plus a
one-time fee for use of a private room. It costs $405
for 15 people. The total cost, y, is a linear function of
the number of x people.
Write an equation in slope-intercept form for this function?
Ashley is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices.
Company A charges $77 and allows unlimited mileage.
Company B has an initial fee of $65 and charges an additional $0.80 for every mile driven.
For what mileages will Company A charge less than Company B?
Use m for the number of miles driven, and solve your inequality for m.
Answer:
Anything above 15 miles, so x>15
Step-by-step explanation:
When you solve this by using an equation, you would get 77=65+0.80m (0.80 m because slope is 0.80 and m is mileage you multiply by). You would subtract 64 from both sides, so 12=0.80m and then you divide 0.80 by 12 to get m by itself to get 15. 15 miles is when both companies cost the same, so anything above 15.

Which of the following shows finding the sum of 4 and -8?
Answer:
-4
Step-by-step explanation:
count by a number line and you will see
Answer:
the answer is -4
Step-by-step explanation:
First you have to determine which sign is bigger. The number 8 is greater than 4 so we have to use the negative sign. now we can subtract or add. eight minus or plus four is four or twelve. so if we add or subtract the negative sign and the number four together we will get negative four or twelve. This is how you get the sum for negative four and eight. Hope this helps!
lindsay has 7/8 yards of fabric. to make a purse, she needs 2/3 of the fabric how much fabric did she use?
Answer:
Lindsay used 16/24 yards of fabric and has 5/24 yards left over
Step-by-step explanation:
7/8 - 2/3 = ?
Since both fractions have unlike denominators, we are gonna have to rewrite the fractions so we can subtract. We are gonna find the least common denominators, to be able to subtract.
(7/8 x 3/3) - (2/3 x 8/8) = ?
Complete the multiplication and the equation becomes :
21/24 (7/8) - 16/24 (2/3) = 5/24
Word problem for 3x(5+8)
Answer:
The answer is 39x.

Jared wants to make a scale drawing of his bedroom. His bedroom is a rectangle with a length of 600 cm and width of 400 cm. He decided on a scale of 1 to 50. 1.Jared's bedroom door is 60 cm wide. How wide should the door be on the scale drawing? Explain how you know. 2.Jared's bed measures 4 cm by 5 cm on the scale drawing. What are the actual measurements of his bed?
Answer:
(1) 1.2 cm
(2) 200 cm by 250 cm
Step-by-step explanation:
The scaled dimention = (Actual dimension) x (scale factor) ...(i)
The given scale factor =1/50
(1) The actual width of the bedroom door= 60 cm.
So, from equation (i),
the width of the door on the scale drawing= 60 x (1/50)=1.2 cm
(2) The scaled dimension of the bed is 4 cm by 5cm.
So, the scaled width of the bed = 4cm and
the scaled length of the bed = 5cm.
So, from equation (i),
4 cm = (Actual width) x (1/50)
So, Actual width = 50 x 4 cm = 200 cm.
And, 4 cm = (Actual length) x (1/50)
So, Actual width = 50 x 5 cm = 250 cm.
=Hence, the actual measurements of his bed is 200 cm by 250 cm.

find the value of x root (4/7)^2x-1=16/49
Answer:
[tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given expression:
[tex](\frac{4}{7}) ^{2x - 1}[/tex] = [tex]\frac{16}{49}[/tex]
Solve for x;
Solution:
16 = 4²
49 = 7²
So;
[tex](\frac{4}{7}) ^{2x - 1}[/tex] = [tex]\frac{4^{2} }{7^{2} }[/tex]
[tex](\frac{4}{7}) ^{2x - 1}[/tex] = [tex](\frac{4}{7} )^{2}[/tex]
Now;
2x - 1 = 2
2x = 3
x = [tex]\frac{3}{2}[/tex]

I really don't understand this
Answer:
-1
Step-by-step explanation:
The mean is the sum of all values divided by the amount of values.
We take the sum of all the numbers:
-3 + -8 + 12 + -15 + 9
-11 + 12 + -15 + 9
1 + -15 + 9
10 + -15
-5
We then divide the sum by how many number we have (we are given 5 numbers):
-5/5 = -1
Therefore, our mean is equal to -1.
Answer:
-1
Step-by-step explanation:
-3 + -8 + 12 + -15 + 9 = -5 Now divide it by the amount of numbers given. -5 / 5 = -1
A bee flies at 12 feet per second directly to a flower bed from its hive. The bee stays at the flower bed for 13 minutes then flies directly back to the hive at 8 feet per second. It is always away from the hive for a total of 15 minutes. What equation can you use to find the distance of the flower bed to the hive?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Rate of flight = 12 feets per second ; from hive to flower bed
Minutes stayed at flower bed = 13 minutes
Rate of flight = 8 feets per second ; from flower bed to hive
It is always away from the hive for a total of 15 minutes
What equation can you use to find the distance of the flower bed to the hive?
Distance = speed * time
Time = distance / speed
Let distance from flowerbed to hive = d
Time from hive to flower bed = d/12
Time from flower bed to hive = d / 8
Hence, total time taken;
d/12 + 13 + d/8 = 15
Converting minutes to seconds
d/12+ 13*60 + d/8 = 15*60
d/12 + 780 + d/8 = 900
Take the L. C. M
(2d + 18720 + 3d) / 24 = 900
5d + 18720 = 21600
We can also solve for d
5d = 21600 - 18720
5d = 2880
d = 576 feets
