If f(x)=3x+2, what is f(3)-7
Answer:
[tex] \orange{ \bold{f(3) - 7 = 4}}[/tex]
Step-by-step explanation:
[tex]f(x) = 3x + 2 \\ \\ plug \: x = 3 \\ \\ f(3) = 3(3) + 2 = 9 + 2 \\ \\ f(3) = 11 \\ \\ f(3) - 7 = 11 - 7\\ \\ \purple{ \bold{f(3) - 7 = 4}}\\ \\ [/tex]
Stefan sells Jin a bicycle for $127 and a helmet for $17.The total cost for Jin is 120% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally?How much money did he make by selling the bicycle and helmet to Jin?
Answer:
Stefan spent $120 originally
He made $24 dollars by selling the bicycle and helmet to Jin
Step-by-step explanation:
First, find the total cost:
127 + 17
= 144
To find the original cost, divide this by 1.2
144/1.2
= 120
So, Stefan spent $120 originally.
Now, find how much he made by subtracting 120 from 144:
144 - 120
= 24
So, he made $24 dollars by selling the bicycle and helmet to Jin.

eve plays basketball. she makes 4 free throws for every 3 free throws that she misses. if she missed 24 free throws at her last practice, how many free throws did she make?
Answer:
She made 32 free throw shots.
Step-by-step explanation:
Based on the given information, one can form the general equation;
[tex]\frac{made}{missed}[/tex]
Substitute in the given values;
[tex]\frac{4}{3}[/tex]
Assuming that the rates at which this proportion exists is constant, and one knows the number she missed, but not the number she made then one can say;
[tex]\frac{made}{missed}= \frac{4}{3} = \frac{made}{24}[/tex]
Solve the proportion using cross products;
[tex]\frac{4}{3}=\frac{made}{24}\\\\\\(4)(24)=(3)(made)\\\\96=3made[/tex]
Inverse operations,
[tex]96=3made\\/3\\\\32=made[/tex]
Answer:
32 free throws

One number is 4 more than another, and their sum is 60. What is the smaller number?
If x = the larger number and y = the smaller number, then which of the following systems could be used to solve the problem?
x + y = 60 and -x + y = 4
x + y = 60 and x + y = 4
x + y = 60 and x - y = 4
Unlimited Attempts Remain
Answer:
Step-by-step explanation:
The system is
x+y=60 and x-y=4
If we get the difference between the two equations above we get
x+y-x+y=60-4
2y=56
y=28

Three tanks are capable of holding 361,841, and 901 of the greatest vessel winch can be used to fill each one of them on exact number of time
Answer:
Tank which is capable of holding 1 can fill each one of the tanks an exact number of time.
Step-by-step explanation:
Three tanks are capable of holding [tex]361,841,901[/tex]
To find which tank can be used to fill each one of them an exact number of time, find [tex]HCF(361,841,901)[/tex]
[tex]361=19^2\\841=29^2\\901=17(53)[/tex]
Therefore,
[tex]HCF(361,841,901)=1[/tex]
So, tank which is capable of holding 1 can fill each one of the tanks an exact number of time.

A F is 13 using pythagorean theorem on triangle CED and applying the hypotenuse length to A F.
ABC is similar to triangle CED and is dilated by a factor of 3 so the base is 36.
using pythagorean theorem on triangle ABC gets the hypotenuse length of 39 which can be applied to FE
add all the values together
39 + 13 + 15 + 36 +12 +5 = 120

Paula has $50 in a savings account that earns 5% interest per year. The interest is not compounded .How much will she have in 1 year?
Answer: $52.50
Step-by-step explanation:
There is $50 in the account and it earns interest at a rate of 5% a year.
This interest is not compounded therefore it is simple interest.
To calculate amount earned with simple interest is:
= Deposit * ( 1 + rate * time)
= 50 * ( 1 + 5% * 1 year)
= $52.50

−2−7p<26
Step 1: Simplify both sides of the inequality.
−7p−2<26
Step 2: Add 2 to both sides.
−7p−2+2<26+2
−7p<28
Step 3: Divide both sides by -7.

Answer:
n = 2
Step-by-step explanation:
(6n - 7) + (8n + 2) = 23 (Combine like terms)
14n - 5 = 23 (Add 5 from both sides)
14n = 28 (divided 14 from both sides)
n = 2
