Answer:
2 outfits
Step-by-step explanation:
first you have the total amount of money he has.
next subtract the amount of money he spends on the new bicycle
500-273.98=226.02
next find the total cost of the 3 bicycle reflectors
7.23 times 3 = 21.69
Subtract that total from the remaining amount of money left
226.02 - 21.69 = 204.33
Then subtract the helmet from the remaining money
204.33 - 42.36 = 161.97
now divide the remaining money by 78.12 to find out how many outfits he can buy
161.97 / 78.12 = around 2.07
So the answer is he can only buy 2 outfits with the remaining money
(you can not buy 2.07 outfits)

Answer:
d, 700
Step-by-step explanation:
it's the only one that makes sense
PART A
Coefficient
Coefficient h is 7.50
Coefficient s is 0.20
Variable
h and s
Constant
40
PART B
7.50h + 0.20s + 40
= 7.50(25) + 0.20(300) + 40
= 187.5 + 60 + 40
= 287.5
She earns $287.5
PART C
Yes, the coefficient of h would change to 9, the rests are still the same. Because she's no longer receive 7.50 per hour, and start earning 9 per hour, so the coefficient should change.
The expression would be
9h + 0.20s + 40
Since it is parallel, gradient must be the same so it will be 1/2
y=1/2x+c
-7=1/2(0)+c
c=-7
equation is y=1/2x-7
Standard for is x × 10 ^I
where,
I = indice
10 > x < 0
you cannot write this is standard form with putting in what they stand for. However you can simplify it -
4(8m-7n) +6(3n-4m)
32m - 28n + 18n - 24m
8m - 10n
but hey I am from England do what we call standard form might be different
