Answer:
1st question: M=22.62 while C=75.38
2nd question: M=.22 while C=1.97
Step-by-step explanation:
If a mirror costing x dollars is marked up 30%, then we have to find x such that 30%x+x is 98 dollars.
We are solving:
.3x+x=98
Combine like terms:
1.3x=98
Divide both sides by 1.3:
x=75.38
M=98-75.38=22.62
C=75.38
So M=22.62 while C=75.38.
If ream of paper cost x and is marked up 11%, then we have to find x such that 11%x+x is 2.19.
We are solving:
.11x+x=2.19
1.11x=2.19
x=1 97
M=2.19-1.97=.22
So M=.22 while C=1.97
Answer:
z=2
Step-by-step explanation:
2z-6=2(2+2)-10 Distribute.
2z-6=4+4-10 Combine like terms.
2z-6=-2 Add 6 on both sides.
<u>+6 +6</u>
2z=4 Divide by 2 on both sides.
<u>/2 /2</u>
z=2
Hope this helps! Have a great day ^^

Answer:
n ≥ -3
Step-by-step explanation:
If n can be <em>no less than</em> -3... then we know that n has to be bigger than or equal to -3.
This could also be said as <em>greater than or equal to</em> -3
Conveniently enough... there is a sign for <em>greater than or equal to</em> and it is ≥
