Karim is ordering video games. Each game costs 39.99$, and there is a 4.85$ shipping charge per order. How much will it cost him to order any number of video games?
Answer:
Each game would be 44.84 per order, so 2 games would be 89.68 and so forth.
Step-by-step explanation:
Take 39.99 and add 4.85 and that gives you the total for 1 game per order.

Zach and Ginny are building model cars. Ginny's car is 2 more than 3 times the length of Zach's car. The sum of the lengths of both cars is 30 inches. Write an equation to determine the lengths of Zach's and Ginny's cars.
3x + 2 = 30
x + 2 + 3x = 30
2x + 3 = 30
x + 2x + 3 = 30
Answer:
x + 2 + 3x = 30
Step-by-step explanation:
Both lengths are unknown, but Ginny's car length is described in terms of Zach's car length, so we choose a variable for Zach's car length.
Let x = Zach's car length.
Zach's car length is x.
"Ginny's car is 2 more than 3 times the length of Zach's car."
Ginny's car length is 2 + 3x.
Add the lengths:
x + 2 + 3x
"The sum of the lengths of both cars is 30 inches."
x + 2 + 3x = 30
Answer: x + 2 + 3x = 30

What is the y-intercept of 6x - 4y = 12?
Answer:
(0,-3)
Step-by-step explanation:
I used desmos
Answer:
y int = -3
Step-by-step explanation:
we get the y int when x = 0. so 6(0)-4y=12 would get us y= -3
Point A is located at -0.75 and point B is located at 0.25 on a number line. Which expression shows how to find the distance between points A and B?
A. |–0.75| – 0.25
B. |–0.75 + 0.25|
C. |–0.75 – 0.25|
D. |0.75 – 0.25|
Answer:
Should be C sorry if not
Step-by-step explanation:
When I do the math in my head I take the distance between 0.75 and 0 and the distance between 0.25 and 0 and add them together giving me the distance between the two points. To get that distance you would subtract the two numbers from each other with the absolute value brackets on the outside of the equation so it will not make the negative a positive. If the negative is a positive, it would make it 0.50 which would be incorrect. The distance between the two points here would be 1.0 if that was the equation. That is a way I used to figure out equations like this when I was younger. Take it for what it is worth.

why do you multply by a power of 10 when writing a repeating decimal as a fraction
The goal is to multiply by a certain number (10, 100, 1000, etc.) so that when the original number is subtracted from the multiple, the repeating element cancels out. 10x = 2 is the result of multiplying by ten.

Somebody help me?
I’ve been stuck on the same question for days now
Answer:
7
Step-by-step explanation:
You've said that both triangle are equal.
This means, both are in proportion
Let the unknown side be x
4 : 5 : x = 36 : 45 : 63
Divide LHS by 9
4 : 5 : x = 4 : 5 : 7
Since you may see x and 7 are same. So, the missing side is 7.
Answer:
Step-by-step explanation:
[tex]\frac{AB}{PQ} = \frac{BC}{QR}[/tex] #1 Find same sides
So, [tex]\frac{4}{36} =\frac{BC}{63}[/tex] #2 fill it in.
36BC= 252 #3 Cross multiply.
[tex]\frac{36BC}{36}[/tex]= [tex]\frac{252}{36}[/tex] #4 Divide by 36
BC= 7 #5 Here's your answer!
If you want to check, plug the sides in.
[tex]\frac{4}{36} =\frac{5}{45} =\frac{7}{36}[/tex]
[tex]\frac{1}{9} =\frac{1}{9} =\frac{1}{9}[/tex]
The siplified fractions should all equal the same number. If they do, the triangles are similar.
Hope this helps!

Answer:
x = 6, BC = 60
Step-by-step explanation:
6x + 2x + 1 = 81
8x + 1 = 81
8x (+ 1 - 1) = 81 - 1
8x = 80
8x/8 = 80/8
x = 10

Simplify the radical
[tex] - 2 \sqrt{54} [/tex]
please explain process!
Answer:
Step-by-step explanation:
54 = 6*9
That means there are 3 threes and 1 two
54 = 2*3 * 3 * 3
There are a pair of 3s and a two and a 3 left over.
The two and the three remain under the root sigh.
One of the pair of threes comes out of the root sign.
The other one is thrown away.

2 25 divided by 11 10 in fraction
Answer:
[tex] \frac{4}{55} [/tex]
Step-by-step explanation:
[tex] \frac{2}{25} \div \frac{11}{10} [/tex]
[tex] \frac{2}{25} \times \frac{10}{11} [/tex]
[tex] \frac{2}{5} \times \frac{2}{11} = \frac{2 \times 2}{5 \times 11} [/tex]
[tex] \frac{4}{5 \times 11}[/tex]
[tex] = \frac{4}{55} [/tex]
The given information is,
→ (2/25) ÷ (11/10) = ?
Let's find the required solution,
→ (2/25) ÷ (11/10)
→ (2/25) × (10/11)
→ 20/275
→ 4/55 {simplest form}
Hence, 4/55 is the answer.
