Answer:
Infinitely many solutions
Step-by-step explanation:
A.
5x + 3(x – 5) = 6x + 2x – 15
5x + 3(x) + 3(–5) = 6x + 2x – 15
5x + 3x – 15 = 8x – 15
8x – 15 = 8x – 15
This equation has infinitely many solutions.
Why? because they have the same terms on both sides of the equation, everything is the same.
B.
One property that was used to solve this equation is the distributive property 3(x – 5).
Hope this helps!

<h3>
Explanation:</h3>
What we know:
- Mary is 1st
- Isabella is a few seconds behind Mary
- Pilar is two places behind Isabella
- Anna is ahead of Pilar
How to solve:
Using Mary as a starting point, we can make accurate guesses to each person's rank.
<h3>
Process:</h3>
Mary
1st place, known constant
Isabella
2nd place, just behind Mary
Pilar
4th place, 2 places behind Isabella
Anna
3rd place, ahead of Pilar and behind Isabella
<h3>
Solution:</h3>
___________
Place | Name
1st | Mary
2nd | Isabella
3rd | Anna
4th | Pilar

Find the amount of the increase:
8.13 - 6.19 = 1.94
Divide the amount of the increase by the original price:
1.94 / 6.19 = 0.3134
Multiply by 100:
0.3134 x 100 = 31.34%
Round to the nearest tenth = 31.3%
Answer:
Each pack of chicken costs $8 and each pack of beef costs $9.24.
Step-by-step explanation:
This question can be solved using a system of equations:
I am going to say that:
x is the cost of each pack of chicken.
y is the cost of each pack of beef.
2 packs of chicken and 3 packs of beef for $42.50.
This means that
5 packs of chicken and 6 packs of beef for $94.25.
This means that
We have to solve the following system:
I will use the addition method, multiplying the first equation by -2, and adding to the second
-4x + 5x - 6y + 6y = -85 + 94.24
x = 9.24.
And
Each pack of chicken costs $8 and each pack of beef costs $9.24.
Answer:
(x-2)(x-4)
Step-by-step explanation:
First into the X puzzle
8 is on top and 6 is on bottom
Find to number at multiples to 8 and adds to 6
the two numbers are 2 and 4 Then write numbers into factor form
that is (n-2)(n-4)
the factor form should multiples to get F(n)=n²-6n+8
the zeros are 2 and 4 Btw
I hope this helps you
