Drew and Danielle are sightseeing for the day. Between the two of them they take 118 pictures. If Drew takes 14 more than three times as many pictures as Danielle, how many pictures for each friend take?
Answer:
Drew = 92 pictures, Danielle = 26 pictures
Step-by-step explanation:
Amount of pictures Drew has = x
Amount of pictures Danielle has = y
First make a system of equations:
x + y = 118
x = 3y + 14
Then solve with substitution:
(3y + 14) + y = 118
4y = 104
y = 26
x + 26 = 118
x = 92

The cost for a business to produce "x" television commercials in 1 year is $225x + $17,000. How many commercials can the company produce in 1 year at a cost of $35,000
We are required to find how many commercials the company can produce in year at a cost of $35,000
The company can produce 80 commercials in year at a cost of $35,000
Given:
C(x) = $225x + $17,000
If C(x) = $35,000
Then,
C(x) = $225x + $17,000
35,000 = 225x + 17,000
subtract 17,000 from both sides
35,000 - 17,000 = 225x
18000 = 225x
divide both sides by 225
x = 18,000 / 225
x = 80
Therefore, the company can produce 80 commercials in year at a cost of $35,000

A recipe for 10 bran muffins calls for 1 cup of flour. The number of muffins that can be made varies directly with the amount of flour used. There are 3 1/2 cups of flour available. How many muffins can be made?
Answer:
35
Step-by-step explanation:
3 1/2 x 10 =35
make 3 1/2 into an improper fraction: 3 x 2 + 1 = 7/2
make 10 into a fraction: 10/1
find the LCD (least common denominator) for each number:
10/1 = 20/2
7/2 = 7/2
20/2 x 7/2 = 70/2 = 35
:)
Answer:
35
Step-by-step explanation:
For 1 cup of flour, you make 10 muffins. Just by reading the problem, you see that the number of muffins, 10, is 10 times the number of cups of flour, 1.
For 3 1/2 cups of flour, you make 10 times that number muffins.
3 1/2 × 10 = 3.5 × 10 = 35
Answer: 35 muffins
You can also use a proportion.
1 cup flour is to 10 muffins as 3.5 cups flour is to x muffins.
1/10 = 3.5/x
Cross multiply:
1 × x = 10 × 3.5
x = 35
Answer: 35 muffins

so you would graph at (2,-1) i think
3b- 4/2 = c , for b
please explain the steps
Answer:
b = c/3 + 2/3
Step-by-step explanation:
3b - 4/2 = c
the goal is to have b all by itself on one side of the equals sign.
start by moving the fraction over to where c is by adding.
3b = c + 4/2
adding -4/2 and +4/2 together makes it a 0 on the b side so there's no need to write anything in that space anymore.
Now 3b are next to each other which means they are multiplying. To move 3 we need to do the opposite (divide by 3 on both sides of the equal sign)
b = c/3 + 2/3
notice I divided both c and 4/2 by 3. 4/2 = 2 so I changed it to 2, then divided by 3

Answer:
SF = 2/5
Step-by-step explanation:
The side on figure A which has the 10 is between angles with one mark and 2
The side on figure B which has the 4 is between angles with one mark and 2
The scale factor is what we multiply 10 by to get 4
10 * SF = 4
Divide each side by 10
10 * SF /10= 4/1-
SF = 4/10
SF = 2/5

Answer:
m=11, x=6, h=5 2/3
Step-by-step explanation:
8(m-5) = 48
m-5 = 48/8 = 6
m = 6+5 = 11
m = 11
x + 7 = 13
x = 13-7 = 6
x = 6
3h - 5 = 12
3h = 12 + 5 = 17
h = 17/3 = 5 2/3 or 5.67

If Tristan wants to stretch the spring by 9 inches, how many kilograms of weight must he apply to it?
Answer:
Step-by-step explanation:
Substitute y = 9 into the equation y = 3x, or locate the answer on the graph:
y = 3x
9 = 3x.
Divide both sides of the equation by 3:
[tex]\frac{9}{3}[/tex] = [tex]\frac{3x}{3}[/tex]
3 = x
The spring stretches 9 inches with 3 kilograms of weight attached to it.
