Answer: 5 times
Step-by-step explanation:
Let the number of times that he saved $75 be x.
Let the number of times that he saved $150 be y.
Therefore, based on the information given in the question, we can form an equation which will be:
x + y = 8 ...... i
75x + 150y = 825 ....... ii
From equation I,
x + y = 8
y = 8 - x....... iiii
Put equation iii into ii and this will be:
75x + 150y = 825
75x + 150(8 - x) = 825
75x + 1200 - 150x = 825
75x - 150x = 825 - 1200
-75x = -375
x = 375/75
x = 5
He saved $75 5times from his paycheck.
Answer:
Number of sides of the polygon
Step-by-step explanation:
The formula 
is the sum of the measures of interior angles. So that's what S stands for. The only other variable remaining is n which is the number of sides of the polygon.
There's nothing I can do to help you understand this, you just have to memorize it.
Hello,
Let's x and y the 2 numbers
x*y=24
x+y=-11==>x=-11-y
==> (-11-y)y=24
==>-11y-y²-24=0
==>y²+11y+24=0
Δ==11²-4*24=25=5²
y=(-11+5)/2 or y=(-11-5)/2
==>(y=-3 and x=-11+3) or (y=-8 and x=-11+8)
Sol={(-8,-3),(-3,-8)}
The 2 numbers are -3 et -8.
