Every absolute value MUST be 0 or greater (positive); thus, <span>| 5x + 13| = -7 has no solution due to the - number on the right.

Answer:
604,800 seconds in a week
Step-by-step explanation:
hope this helps!
Using the PSN method:
P = -9
S = 8
So N = 9,-1
Using 9 and -1 in the original equation gives:
Answer:
y=-2x-5
Step-by-step explanation:
slope (m)= -2, point (-4,3) put in y=mx+B
3 (y)= -2 [m](-4) + B
3=-2 (-4)+B. - multiple -2 and -4
3= 8 +B. - two negatives. multipled gives you a positive
3=8+B. - subtract 8
-8 -8
-5=b
y= -2x-5
So first you need to find a formula for who has what!
Because nobody said what chase had, chase is our variable!
Chase = x
Sophie = x-6 (six less than Chase so subtraction)
Jonah = x•3 (three times the amount of Chase)
Now you will put all of this in an equation- adding everybody together! The total is 89 so that will be what’s after the equal sign!
Your equation: x+x-6+x•3=89
First you will use PEMDAS, since there are no parentheses or exponents- you’ll do multiplication first!
x+x-6+(x•3)=89
When you multiply that out, you will be left with: x+x-6+3x=89
Second you will add all common terms! Remember- the 3x means there are THREE x’s in that one spot. Take out all x’s in the equation and add them together!
x+x+3x=5x
Now you are left with:
5x-6=89
Now you will solve this like a regular equation! First, you have to move the -6 to the right so you will do the inverse operation (the opposite sign) and add 6 to both sides! 89+6 is 95 and -6+6 is 0, so the 6 on the left cancels out and isn’t there anymore!
Now you have 5x=95. To get the x by itself, you will divide both sides by 5! (Once again, doing the inverse operation! Since 5 and x are being multiplied, you have to divide.)
When you divide, you are left with x=19. In this question, the answer is:
Each person has $19.
