Biggest number would be 8743, but 3 must be hundreds so the biggest will be 8374. Which is eight thousand three hundred seventy four
We know that
[perimeter of rectangle]=2*[(x+6)+(x-4)]----> 2*[2x+2]----> 4x+4
[area of rectangle]=(x+6)*(x-4)--------> x²-4x+6x-24--------> x²+2x-24
the answer is the option <span>A
Perimeter = 4x + 4 and Area = (x + 6)(x - 4)</span>
Answer:
b. No she will not have enough bracelets for all 32 classmates if she orders 5 more packages of bracelets
Step-by-step explanation:
write out the equation
p=the number of packages she needs to buy
32=5+4p
subtract five from both sides
32-5=5-5+4p
27=4p
dived both side by 4
27/4=4p/4
6.75=p round to 7
Check your answer:
4 x 7 = 28
add the number of bracelets she already has
28 + 5 = 33 bracelets
33>32
So <u>7 packages</u> is the minimum number of packages she needs to buy
Answer:
20
Step-by-step explanation:
The cost of the x mangoes was ...
c = 10(x/4)
The revenue from the sale of mangoes was ...
r = 20(x-5)/5
The profit is the difference between revenue and cost:
10 = r - c = 20(x -5)/5 -10(x/4) = 1.5x -20 . . . . substitute and simplify
30 = 1.5x . . . . . add 20
20 = x . . . . . . . .divide by 1.5
The trader bought 20 mangoes.
_____
<em>Check</em>
He paid 20(10/4) = 50 naira. He sold the 15 good mangoes for 20/5(15) = 60 naira, so made a 10 naira profit.
