Answer:
Step-by-step explanation:
it makes 253 copies in 5 mins 45 seconds
that is to say, 253 copies in 345 seconds
In 1 minute (60 seconds) it will make X copies.
Lets draft an equation to easily express and simplify the problem.
253 copies = 345 seconds
X copies = 60 seconds
lets cross multiply and solve for X
Theefore:
x * 345 = 254 * 60
345x = 15,240
divide through by 345
x = 15240 / 345
x = 44.17
therefore, the copying machine makes approximately 44 copies per minutes
Answer:
N = 2
Step-by-step explanation:
n - 3 = -1 Original
n ( -3 + 3 ) = ( -1 + 3 ) Add 3 on both sides
n = 2 Simplify
Check:
2 - 3 = -1 Replace
- 1 = -1 Solve
Correct!
Answer:
4277.6
Step-by-step explanation:
Hello, I can help you with this
Step one
find the profit using a simple rule of three
if
4000 ⇔ 100%
then, how much(x) is 6.94?
x ⇔ 6.94%
the relation is
the profit is 277.6
hence, her balance after one year is the initial amount plus interest earned
balance= 4000+277.6
balance= 4277.6
I hope it helps, Have a great day
Subtract 7 from both sides then divide both sides by X so the correct answer would be B.) y= n-7/x
There is 7,000 female students, and 5,000 male students. Because, if there was 2,000 more female students then male, you have to find out what two numbers add up to 12,000. (Tip, to make it easier, take away the thousands, like 7+5)
