The answer in scientific notation is 1 * 10 to the 15 power.
The result is 1,000,000,000,000,000.
In word form its one quadrillion.
Answer:
C. 2, -1, -5, -8.
Step-by-step explanation:
a = first term = 2
second term, a2n-1) - 3 = 2 - 3 = -1
third term = -2 - 3 = -5
fourth term = -5 - 3 = -8.
Answer:
a. x=-17, y=27
b. x=0, y=-6
c. x=9, y=-1
d. undefined
e. x=4, y=-6
f. x=4, y=0
Step-by-step explanation:
a. 3x+y=24
y=3x+24
-x+3x+24=-10
2x=-34
x=-17
-(-17)-y=-10
17-y=-10
-y=-27
y=27
b. 3y=-18
y=-6
-6=-x-6
0=x
c. -2x+17=8-x
9=x
y=8-9
y=-1
d. x-7=x+7
x-14=x
-14=0
e. -4x+10+2x=2
-2=-8
x=4
y=-4(4)+10
y=-16+10
y=-6
f. x+2y=4
x=4-2y
-4(4-2y)-3y=16
-16+8y-3y=16
-16+5y=16
5y=0
y=0
x+2(0)=4
x=4
Yes your method is correct. But you will need to express it in percentage in the end.
So,
2 x 12 ( dozen ) = 24
24 - 18 = 6
6 / 12 = 0.5
$6 is how much you earned by selling 12 hair products.
Hence, $0.50 is how much you earned per bottle.
Transfering 0.5 into percentage would be 0.5 x 100.
Your percentage mark up would be 50 %
Since 2 is a whole number , the 2 would go in front of the decimal , 2.00 like so , and since you have 7 tenths combined with the 2 and the tenths place is just after the decimal, it'd look like this 2.7
