The answer you have is good. You don't need to change anything.
Answer:
1. 14
2.400 pieces
Step-by-step explanation:
1. 8.02+6.1= 14.12, since its less than 14.5 you must round down to 14
2. remember 1 meter is 100 centimeters, thus to find how many centimeters are in 24 m multiply 100 by 24. this will get 2400 centimeters
divide 2400/6 and you will get 400
Answer:
variables look like letters of the alphabet.

Answer:
8
Step-by-step explanation:
Let's just call the number x for simplicity.
So, 7x is 8 less than x².
Putting this into an equation would look like this
x² - 8 = 7x
It looks like we'll have to factor this to solve. Before we do that we need to move the 7x to the left side so that everything is together.
x² - 7x -8 = 0
Now, we can proceed. To factor we first need to find the factors of -8.
The factors of -8 are
-2 ⋅ 4, -4 ⋅ 2, -1 ⋅ 8, 1 ⋅ -8.
We need to find the pair of factors that adds up to -7. The only ones that do are -1 and 8.
So now that we have these we can create a pair of binomials using them. This will give us the factored form of this equation.
( x + 1 ) ( x - 8 )
To find the solutions we will have to set them to 0 and solve each of these binomials individually.
x - 1 = 0
x = 1
So, one of the solutions is 1. It's not the one we want, since it's positive.
x - 8 = 0
x = 8
This is the one we want since it is positive.
Answer:
y = 3/7x
Step-by-step explanation:
Well slope-intercept form means this -----> y=mx+b
m = slope
b = y- intercept
In the question given they already telling us the slope (3/7) and the y intercept (0) so to put it into slope intercept form it will be ---> y= 3/7x
* If your y - intercept is zero you don't need to replace it with the b because its zero it means nothing (it has no value)
Hope this helps!!!
