How many solutions does the equation have? f + 7 = f - 3
Answers
Answer:
there is no solution
Step-by-step explanation:
Answer:
no solutions
Step-by-step explanation:
Given
f + 7 = f - 3
Given any value for f then f + 7 ≠ f - 3
Hence the equation has no solution
Through solving we obtain
f + 7 = f - 3 ( subtract f from both sides )
0 + 7 = - 3
7 = - 3 ← not possible, thus no solution

- b+3=2(k+3)
- b-2=3(k-2)
- 2b+1=5k
- 2b-5k=-1
- b-2k=3

Hi there!
To solve your answer, since we know a = 7, we can easily solve your equation.
But before we go onto that, I want to show you a tip or two about solving equations with variables next to numbers.
When you have a number, and a variable attached to it, it means to multiply.
Now, to make this equation look a little easier, lets rewrite it.
9 × 7 - 5 × 7 = ___
According to PEMDAS, we won't go straight from left-to-right when solving here. We'll skip around a little.
9 × 7 = 63.
5 × 7 = 35.
Now, since we've multiplied the two numbers, its time to subtract them.
63 - 35 = 28. Sooooo........
9 × 7 - 5 × 7 = 28
Hope this helps!
Message me if you need anything else, I'd be happy to help you out! :D
when a number is attached by a variable, that usually means that it is attached by multiplication so, i multiplied 9 times 7 and got 63 then i multiplied 5 times 7 and got 35 then subtract 63 and 35 and i got 28
i hope this helps :)

Then
The amount of money that the customer will
save during tax free period = 225 * (4.75/100)
= 225 * 0.0475
= 10.687
So the person will save $10.687 or you can take it as $10.69 during the tax free period.

The two third of the given number,
⇒ (2/3)x120 = 80
The given number is,
120
We have to find its two third:
To find this,
First multiply this number wit 2 then,
2x120 =240
Then divide the number by 3
240/3 = 80
Thus two third of the given number can be written as,
(2/3)x120
= (2x120)/3
= 240/3
= 80
Hence,
⇒ (2/3)x120 = 80

The number of cups of chocolate chips that should be used for 10 dozen cookies is 1 2/3 cups.
Based on the information given, the expression to solve the question will be:
0.5/3 = x/10
Cross multiply
3 × x = 0.5 × 10
3x = 5.
x = 5/3
x = 1 2/3 cups
Therefore, the number of cups of chocolate chips that should be used for 10 dozen cookies will be 1 2/3 cups.
Read related link on:
To answer this question, you should set up a proportion that demonstrates the ratio of chocolate chips to cookies.
36 and 120 are used because 1 dozen=12.
Cross multiply and solve for x to get the answer.
The answer is cups.
