Answer:
I can't see the exercise. what do you want?
Start by combining like terms -2x + -3x = -5x. 7 + -9 = -2. You should get -5x - 9.
Answer:
£10
Step-by-step explanation:
There may be a far easier way to do this, but this is how I did it and still came up with the correct solution.
-Assuming they buy at least 15 bags, they will get a 20% discount.
-20% discount would mean they only pay 80% of the original price. 80%=.80
-let x represent number of bean bags
£50 per bean bag multiplied by sale price .80, plus cost of coffee machine £370 must be equal to or less than £1300.
(50x)(.80) + 370 = 1300
Simplify:
40x + 370 =1300
Subtract 370 from both sides
40x = 930
Divide both sides by 40
X=93/4
Simplify fraction
23 1/4
=23.25
But since they cant buy .25 (quarter) of a bean bag, we reduce* to nearest whole number. We can not increase* to nearest whole number as this would exceed their budget.
23 bean bags. They can buy 23 bean bags at £40 each + coffee machine for £370.
£40(23) + £370 = £1290
£1300-£1290=£10
I hope this helps!
The answer is b if you add 3 plus -5 that would have given you negative -2
Answer:
501613 books
Step-by-step explanation:
6.2% of x is 31,100
6.2%=6.2/100=62/1000
(62/1000)*x=31,100
x=31,100/(62/1000) [divide both sides by 62/1000]
x=501612.90=501613 (rounded up)
Hope this helps!
