Answer:
The savings were changed by $88
Step-by-step explanation:
1 backpack costs 8 dollars and they bought 8 of them, you have to multiply 8 dollars by 8 cause there is 8 backpacks which is 64 , pen and pencils for 1 backpack costs 3 dollars , so you have to multiply 3 by 8 cause there are 8 backpacks which is 24. then you add 64 and 24 which is 88

A car factory made 8 cars with a sunroof and 18 cars without a sunroof what is the ratio of the number of cars without a sunroof to the total number of cars?
Answer:
No of cars without sunroof=18
Total no of cars=18+8=26
Now,the ratio of cars without sunroof to total no of cars=18÷26
= 9÷13

b. He cannot with the first but he can with with second. For the first, we have 0=x^2+3. Then subtract 4 from each side and get -3=x^2. This isn't possible in a theoretical term. For the second, you have 0=square root of x -2 or 2=square root of x. That means x is 4.

I WILL MARK AS BRAINLIEST! Choose The inequality that represents the statement and then graph if on The line provided. Lacey has flown at least 120 miles.
Answer: Choice b) [tex]x \ge 120[/tex]
The graph will involve a closed filled in circle at 120, with shading to the right.
See the diagram below.
============================================
Explanation:
The phrasing "at least" means "that amount or more".
Saying "at least 120" is the same as "120 or more".
Therefore, x = 120 is the smallest x can be. That's why we go for [tex]x \ge 120[/tex] which says that either x = 120 or x > 120.
Visually, we'll plot a closed filled in circle at 120 on the number line. The shading will aim to the right to indicate all values larger than 120. The closed/filled in circle is to represent we include 120 (as opposed to an open circle where we exclude it).
Due to the fact that your teacher gave you a blank number line, the placement of 120 doesn't really matter.
400 written as a product of its prime factors is 2 x 2 x 2 x 2 x 5 x 5.
Write 800 as a product of its prime factors.
Answer: 2 x 2 x 2 x 2 x 2 x 5 x 5
Explanation:
We start with the string 2 x 2 x 2 x 2 x 5 x 5
Then we tack on a "2 x" up front, or at the very left, so that we double the result. This is because the jump from 400 to 800 is "times 2".
So we go from 2 x 2 x 2 x 2 x 5 x 5 to 2 x 2 x 2 x 2 x 2 x 5 x 5
We can condense this into [tex]2^5*5^2[/tex]

6(9 + 5x) = 54 +
Hi
to progress in math, you must : know by heart the rules and formulas then train.
rule : a ( b+c ) = a*b + a*c.
this propertie is call distributivity .
so we have : 6 ( 9+5X)
here : a = 6
b = 9
c = 5X
so 6 ( 9+5X) = ?
I let you have a shot. Ask in comments section if you are stuck. But try first !
Answer:
1) rearrange terms:
6(9 + 5x) = 54
6(5x + 9) = 54
2) Distribution :
6(5x + 9) = 54
30x + 54= 54
3) subtract 54 from both side:
30x + 54 = 54
30x + 54 - 54 = 54 - 54
4) Simplify: subtract the numbers
30x = 0
5) Divide both side of the equation by the same term:
30x = 0
30x√30 = 0√30
6) Simplify: cancel term that are in the both numerator and denominator
x = O√30
solution :
x = 0]

how do you rewrite 2^-2
Answer:
[tex]2 ^{ - 2} \\ \frac{1}{2 ^{2} } \\ ( \frac{1}{2} ) ^{2} [/tex]
I hope it helped U
stay safe stay happy
Answer:
1/2^2
Step-by-step explanation:
When you have a number to a negative power, you can rewrite it inverting it's fraction and changing the signal of the power. 2 can be wrote as a fraction like 2/1, so you have 2^-2, it's like 2^-2/1, so you invert the fraction and the signal of the power, and have 1/2^2
4 − (x + 2) < −3(x + 4)
Answer:
x<-7
Step-by-step explanation:
4 − (x + 2) < −3(x + 4)
4 − x - 2< −3x - 12
14 < - 2x
x<-7
Answer and Step-by-step explanation:
First, we need to solve both sides of the equation.
Distribute the negative to the x and the 2.
4 - x - 2 < -3(x + 4)
Distribute the -3 to the x and the 4.
4 - x - 2 < -3x - 12
Combine like terms.
2 - x < -3x - 12
Add 12 to both sides of the equation.
12 + 2 - x < -3x - 12 + 12
14 - x < -3x
Add x to both sides of the equation.
14 - x + x < -3x + x
14 < -2x
*Divide both sides of the equation by -2, and flip the sign.
-7 > x
-7 > x is the answer.
*How this works:
When we flip the sign, we really are just saving ourselves an extra step when dividing numbers (that are negative, only works when number is negative).
14 < -2x
If we were to add to x, and subtract 14, it will look like this:
2x < -14
Then when we divide by 2, we get:
x < -7
This is the same result, but it takes an extra step. Use this way if you forget why you need to flip the sign when dividing by a negative number.

3(x-5)+1=2+x Please put the work!!!!!!!!!!!!!!
Answer:
3(x-5)+1=2+x
3x-15+1=2+x
3x-x=2+15-1
2x=16
x=8
Answer:
x=8
Step-by-step explanation:
3(x-5)+1=2+x
Subtract 1 from both sides.
3(x-5)=1+x
Distribute the 3
3x-15=1+x
Add 15 to both sides.
3x=16+x
Subtract x from both sides.
2x=16
Divide both sides by 2.
x=8

Find the number that makes the ratio equivalent to 1:5.
6:
Answer:
box = 30
Step-by-step explanation:
You could set this up very formally as a proportion. It would look like this.
1/5 = 6/x
Now all you have to do is cross multiiply.
1*x = 5 * 6
x = 30
So the answer that goes in the box is 30
Or you could just say to yourself. "The 1 was multiplied by 6. What do I have to multiply the 5 by to keep the ratio the same?"
The answer is 6
6 * 5 = 30
