Step-by-step explanation:
We have y = 13 - 3x and y = 7 - x.
=> 13 - 3x = 7 - x
=> 2x = 6, x = 3.
Then y = 7 - (3), y = 4.

Solve: 3n - 6 = -8(6 +5n)
and explain how to solve it
Answer:
Step-by-step explanation:
First use distributive property: a(b + c) = a*b + a*c
3n - 6 = -8(6 + 5n)
3n - 6 = 6 * (-8) + 5n *(-8)
3n - 6 = -48 - 40n
Now add 40n to both sides
3n - 6 + 40n = -48 - 40n + 40n
43n - 6 = -48
Now add 6 to both sides
43n - 6 + 6 = -48 + 6
43n = -42
n = -42 /43
Answer:
0.98
Step-by-step explanation:
3n-6=-8(6+5n)
3n-6=-48-40n
3n=-48-40n+6
40n+3n=-42
43n=-42
n=0.98 (I rounded it)
A card is in the shape of a rectangle. The length of the card is 7 cm
and the area of the card is 35 sq cm. What is the width of the card in
centimeters?
lol ok so
7*something or you can make it into a variable x=35
7*x=35
/7 /7
x=5.
what is y = 5/3x + 2
Answer:
Solving for x : x = 3y/5 - 6/5. Solving for y : y= 5x/3 +2
Step-by-step explanation:
Solving for x: Solve for x by simplifying both sides of the equation, then isolating the variable.
Solving for y: Combine 5/3 and x.
You didn't say which one to solve for so I put out both for you.

Can someone help me on thissss
Answer:
100% is 9, 55% is 4.95, 75% is 6.75.
Step-by-step explanation:
Suppose that 100% were [tex]x[/tex]. Then 30% is 27, so [tex]0.3x=27[/tex] and we can divide both sides by 0.3 to see that [tex]x=\frac{27}{0.3}=\frac{27}{\frac{3}{10}} = \frac{27\cdot 10}{3} = 90.[/tex] So 55% is [tex]0.55x = 0.55 \cdot 9 = 4.95[/tex] and 75% is [tex]0.75x = 0.75\cdot 9=6.75[/tex]. (Note that we can divide the value of a percentage by 100 - the same as moving the comma by two places to the left - to get the decimal value.)
How do I do such thing?
Answer:
a= -5
Explanation:
Rewrite the equation to be: 3^a=3^-1 / 3^4
Multiply by adding exponents :))
which would then be 3^a = 3^-5
Then, since the bases are the same then the a would equal negative (-) 5. :))
Hope this helps :)) Plz mark brainlest :))
Serenity is going to invest $130 and leave it in an account for 19 years. Assuming the
interest is compounded continuously, what interest rate, to the nearest tenth of a
percent, would be required in order for Serenity to end up with $230?

3%
Step-by-step explanation:
Solve for the measure
Answer:
A) 130°
Step-by-step explanation:
Angle UTV = angle YTX = 75°
Angle VTW = 55°
so UTW = 75 + 55
if this helps, please give brainliest if possible
Answer:
A
Step-by-step explanation:
∠ UTV = ∠ YTX = 75° ( vertically opposite angles )
∠ VTW = 55° ( angle at centre is equal to arc that subtends it )
Then
∠ UTW = ∠ UTV + VTW = 75° + 55° = 130° → A

The price of bananas can be determined by the equation P=0.25n, where P is the price and n is the number of bananas. What is the constant of proportionality (unit rate)?
Given:
The price of bananas can be determined by the equation P=0.25n, where P is the price and n is the number of bananas.
To find:
The constant of proportionality
Solution:
We have,
[tex]P=0.25n[/tex] ...(i)
where P is the price and n is the number of bananas.
Price P is directly proportional to the number of bananas. So,
[tex]P\propto n[/tex]
[tex]P=kn[/tex] ...(ii)
Where, k is the constant of proportionality.
On comparing (i) and (ii), we get
[tex]k=0.25[/tex]
Therefore, the constant of proportionality is 0.25.
-8x + 10 = -62
4 + 3x = 25
4x + 2x + 5 = 41
5x - 8 = 32
3 + 6x = 21
5 - 2x = 15
8x + 10 = -38
-36 = -4x -16
-5 + 3x = -26
8x - 5 = -29

Katrina bought a new sofa. She was able to pay $100 at the
time she received the sofa. She will pay $22 each month on
the balance. The original cost of the sofa was $298. The
equation 100 + 22 = 298 represents this situation.
Use the equation to determine how many months will it take
Katrina to pay off the sofa.
================================================
Work Shown:
100 + 22x = 298
22x = 298-100 ........ subtracting 100 from both sides
22x = 198
x = 198/22 .............. dividing both sides by 22
x = 9
It will take 9 months for her to pay off the sofa.
She pays the original $100, and then on top of that, she pays an extra 22*x = 22*9 = 198 dollars since she paid $22 per month for 9 months. So this leads to 100+198 = 298 dollars total to help confirm our answer.
