Uh kinda need some more numbers here about the rate
interoperate your solution in the context of the problem.
f(10)=1.75r+9
Answer:
Simplifying
f(r) = 5 + 1.75r
Multiply f * r
fr = 5 + 1.75r
Solving
fr = 5 + 1.75r
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'r'.
f = 5r-1 + 1.75
Simplifying
f = 5r-1 + 1.75
Reorder the terms:
f = 1.75 + 5r-1
Step-by-step explanation:
tada i think
Let's solve for f.
f(10)=1.75r+9
Step 1: Divide both sides by 10
10f/10 =1.75r+9/10
Answer : f=0.175r+9/10

whats the answer to y/6+6=-19
Answer:
y = -150
Step-by-step explanation:
y/6+6=-19
Subtract 6 from each side
y/6+6-6=-19-6
y/6 = -25
Multiply each side by 6
y/6 * 6 = -25*6
y = -150

Julie is out shopping and finds a $96.00 basketball that was marked down by 25%.
How much was the item originally?
Answer: The original price of the basketball was $128.
Step-by-step explanation: The new price is 25% less than the original. That is the same as 25% from 100% is 75%.
So we can use that to calculate the original price:
96 = .75x . divide both sides by .75
96/.75 = x
128 = x That is the original price.
Check: $128 × .25 = $32, the amount of the discount.
$128 - 32 = $96 That is the price Julie paid.

Two sides of a triangle have lengths of 7 and 15. Which inequality represents the possible lengths for the third side?
A) 8 < x < 7
B) 7 < x <15
C) 8 < x < 15
D) 8 < x <22
Answer:
D
Step-by-step explanation:
From the triangle inequality, we know that the two small sides must be greater than the largest side. Let's let x be the third side:
[tex]7+15>x[/tex]
However, 15 can also be our largest side. So:
[tex]7+x>15[/tex]
Let's solve for x for both inequalities.
First inequality:
[tex]7+15>x[/tex]
Add:
[tex]22>x[/tex]
Flip:
[tex]x<22[/tex]
Second inequality:
[tex]7+x>15[/tex]
Subtract 7 from both sides:
[tex]x>8[/tex]
So, we have the compound inequality:
[tex]x>8\text{ and } x<22[/tex]
Combine:
[tex]8<x<22[/tex]
Our answer is D
And we're done!
5 ( f + 4) = 4 ( f - 6)
f = -44
Hope this helps :)
Answer:
The answer is -44
Step-by-step explanation:
First, you use distributive property on each side.
5xf + 5x4 = 4xf-4x6
5f+20=4f-24
Then you subttract 5f to both sides of the equation.
5f+20=4f-24
-5f -5f
20=-1f-24
Next, you add 24 to both sides of the equation.
20=-1f-24
+24 +24
44=-1f
Finally, you divide -1f from each side of the equation.
44=-1f
/-1f /-1f
Your final answer should be -44=f
or f = -44

The sale price of an item is $160 after a 20% discount. What was the original price of the item?
Answer:
200 sorry read that wrong
Step-by-step explanation:
Answer:
The original price of the item is $200.
Step-by-step explanation:
Let the original price be 'x'.
The sale price of an item is $160 after a 20% discount.
i.e. original price - 20% of original price = $160
x-20/100x=160
x-0.2x=160
0.8x=160
x=160/0.8
x=200
Therefore, the original price of the item is $200.

At the fair, Hunter bought 3 snacks and 10 ride tickets. Each ride ticket costs $1.50 less than a snack. If he spent a total of $24.00, what was the cost of each snack?
A) $4
B) $2
C) $5
D) $3
Answer:
d if this helped mark brainliest
Step-by-step explanation:
Each ride ticket is 1.50 less than each snack
t = s - 1.50
hunter spent a total of 24
if hunter bought 3 snacks and 10 ride tickets.
3s + 10t = 24
3s + 10(s - 1.50) = 24
3s + 10s - 15.00 = 24
13s = 39.00
s = 3
t = 1.50
Answer:
D
Step-by-step explanation:
Let s represent the cost of snacks and r represent the cost of the ride tickets.
We know that Hunter bought 3 snacks and 10 ride tickets. This cost in total $24. So:
[tex]3s+10r=24[/tex]
We know that each ride ticket cost $1.50 less than a snack. So, we can write that:
[tex]r=s-1.5[/tex]
We can find s using substitution. Substitute the above equation into the first equation. This yields:
[tex]3s+10(s-1.5)=24[/tex]
Distribute:
[tex]3s+10s-15=24[/tex]
Combine like terms:
[tex]13s-15=24[/tex]
Add 15 to both sides:
[tex]13s=39[/tex]
Divide both sides by 13:
[tex]s=3[/tex]
So, the cost of a snack is $3.
Our answer is D.

X + 7 = 23 middle school work
Answer:
X = 16
Step-by-step explanation:
23 - 7 = 16
Answer: 16
Step-by-step explanation:
23 - 7 = X
To find X we do the inverse of addition which is subtraction. The 7 cancels out and the 23 becomes a 16. We can even check our answer. 16 + 7 = 23
Sam invested $14,000 in a stock that was expected to show an 18% increase in value. If all goes as expected, what will Mr. Bronson’s stock be worth after one year?
a
$11,480
b
$2,520
c
$16,520
d
$252,000
25p
Answer:
C
Step-by-step explanation:
we can convert 18 percent to .18 and then we can multiply 1.18 by 14000 to get our answer. if you don't do the extra 1 before the decimal you will get the 18 percent then have to add it to 14000 so adding the 1 before doesn't affect anything, it just makes it easier, without it it would be a two step problem (adding the .18 to 14,000).
Answer:
C is the right answer
