Hi There!
Alright- Lets do this!
#1: PEMDAS
P

M/D
A/S
(8 + 7) - (8 x 9) + 800 + (50 + 90) + (8 x 9) - (11 - 25)
P - Parentheses
15 - 72 + 800 + 140 + 72 - (-14)
E - Exponents
There are none
M- multiply
there are none
D-Divide
There are none
Add
<span>15 - 72 + 800 + 140 + 72 - (-14)
</span>15 - (72+800+140+72 + 14)
*Note: subtracting a negative number is the same as adding it!*
15-1098
S - subtract
Answer: -1083
Hope this helped!
A positive
as there are 4 negetive multiplied
Answer:
No
Yes
No
Step-by-step explanation:
8 glitter wands for $50. 50/8 = $6.25 for each glitter wand.
1) 4 sparkle wands for $20. 20/5 = $4 for each sparkle wand.
Does NOT have same price per wand as glitter wands.
2) 6 fairy wands for $37.50. 37.5/6 = $6.25 for each fairy wand.
Has the same price per wand as glitter wands.
3) 10 glow wands for $65. 65/10 = $6.50 for each glow wand.
Does NOT have same price per want as glitter wands.
Hope that helps!
Let the value of the vehicle be described by the equation
V = a + bx
where x = number of years since purchase
a,b are constants.
When x = 0, V = $7500. Therefore
a + b*0 = 7500
a = 7500
When x = 7, V = $500. Therefore
7500 + 7b = 500
7b = 500 -7500 = -7000
b = -7000/7 = -1000
The equation is
V = 7500 - 1000x
The slope of this equation is the depreciation rate, and it is -$1000 per year.
Answer: $1000 depreciation per year.
