Answer: $180
Step-by-step explanation:
A store pays $90 and marks it up by 100%. This means that they added 100% of the cost to the cost in order to come up with the selling price.
A hundred percent of a number is the number itself so a 100% of $90 is $90.
Selling price is therefore:
= 90 + 90
= $180
Answer:
x over 10
Step-by-step explanation:
y is one-tenth (/10) of x
y = x / 10
x over 10 is your answer
Hope this helps!
Add 10 to both sides, then multiply by -3 on both sides, so:
-n/3-10=0
-n/3=0+10
-n/3=10
n=10x(-3)
n=-30
Answer: Factors (x + 2)(x + 7)
Solutions x = -2, x = -7
<u>Step-by-step explanation:</u>
h(x) = x² + 9x + 14
∧
1 + 14 = 15
2 + 7 = 9 ⇒ This sum is the coefficient of the middle term!
(x + 2) (x + 7)
To get the solutions, set each factor equal to zero and solve.
x + 2 = 0 x + 7 = 0
<u> -2 </u> <u> -2 </u> <u> -7 </u> <u>-7 </u>
x = -2 x = -7
