1. 1/8 = 0.125 You get this by dividing 1 by 8.
11. the square root of 25/4 is 5/2, or 2.5. You get this by square rooting the numerator and denominator of the fraction.
13. the cube root of 8 is 2, because 2 x 2 x 2 = 8.
Hope this helps
brainliest pls
sorry I didn't do them all cause I have to go
Expand brackets first which would be 13 + - 12 - - 5*. So this would be 13- 12 + 5 = 6
*+5 because 2 negatives make a positive

Answer:

Step-by-step explanation:
1) Split the second term in
into two terms.
1 - Multiply the coefficient of the first term by the constant term.

2 - Ask: Which two numbers add up to 2 and multiply to -35?
7 and -5.
3 - Split 2x as the sum of 7x and -5x.

2) Factor out common terms in the first two terms, then in the last two terms.

3) Factor out the common term x+1.

4) Solve for x.
1 - Ask: When will (x+1)(7x-5) equal zero?
When x + 1 0 or 7x-5=0
2 - Solve each of the 2 equations above.

Your standard equation is y = mx + b
P should be the output (y) because it is the final bill. B should be represented by 200 because the $200 is an additional, once payed fee. M should be 30 because the amount payed for dinner depends on how many people are served.
p = final bill
b = 200
m = 30
x = number of friends
So, your equation would look like p = 30x + 200
Hope this helps!
