A book is on sale for 30% off. The sale price of the book is $14. What is the original price of the book
Answers
Since $14 is the price after a 30% discount then $14 is 70% of the original price.
$14/70=x/100 (100% would be the original price)
1400=70x or 1400/70 = $20!
You can double check the work by taking 30% off the $20 (10% would be $2, 30% would then be $6) 20-6=14!

Nicholas started a canned-food drive at school. The equation representing this is y = 235x + 15, where x is the number of days, and y is the number of cans collected. Explain how to determine how many days it would take to collect 2600 cans.WILL GIVE BRAINLIEST
Answers
Answer:
well, 11 days
Step-by-step explanation:
if you were to put take out the y and put 2600 in the y place (2600=235x+15)
you solve that, and will come to 11 days
further explaining:
2600-15 = 2585
2585 / 235 = 11
( I'm not sure if this is right, the question is worded weird and almost doesn't make sense)
but I think it is looking for substitution
Hope this helps!
Answer:
I am given a number of cans, which is y, and I need to find the number of days, which is x. To do this, I would substitute 2600 for y, to get 2600 = 235x + 15. Solving for x, I would get x = 11. Thus, it would take 11 days to collect 2600 cans.

Step-by-step explanation:
because when 7 crosses the equal to sign it becomes negative and when the x from the other side crosses the equal sign it also will become negative which will become 4x-x=13-7
which is 3x=6 so u divide both sides by the coefficient of x which is three which will give u 2

and that
[tex]\angle 1 +\angle 2 = 180[/tex]
so we substitute angle 2 by angle 1
[tex]\angle 1 +\angle 1 = 180\\\\2\angle 1=180\\\\\angle 1 = 90[/tex]

The HCF of two numbers is 20. The LCM of both numbers is a multiple of 14. One number is greater than the other, work out the smallest possible values of both numbers.
Answers
Answer:
The smallest combination of the numbers is 20 and 140
Step-by-step explanation:
The given parameters are;
The Highest Common Factor HCF of the two number = 20
The Lowest Common Multiple LCM of both numbers = Multiple of 14
Let x and y represent the two numbers, we are given;
x > y
We have;
[tex]L.C.M. = \dfrac{Product \ of \ the \ numbers}{H.C.F.}[/tex]
Substituting the known values, we have;
[tex]x \times 14 = \dfrac{Product \ of \ the \ numbers}{20}[/tex]
The product of the numbers = x × 14 × 20
The possible products of the numbers are;
280, 560, 840, 1,120, 1,400, 1,680, 1,960, 2,240, 2.520, 2,800, 3,080, 3,360, 3,640, 3,920
Dividing the possible products by 20 gives, the smallest quotient that is also a multiple of 20 as 140, from which we have;
20 × 140 = 2,800
Therefore, the smallest combination of the numbers = 20 and 140.

1.It is given that h(x) = 2x − 5. Find h(4)
2.It is given that f(x) = 5x + 2. Find f –1(-3).
Answers
Answer:
h(4) = 3
f-1(-3) = - 1
Step-by-step explanation:
One
h(x) = 2x - 5
h(4) = 2*4 - 5
h(4) = 8 - 5
h(4) = 3
Two
Let y = f(x)
y = 5x + 2 Interchange x and y
x = 5y + 2 Subtract 2 from both sides
(x - 2) = 5y Divide by 5
(x - 2)/5 = y
but y = f'(x)
so f(x) = (x - 2)/5
f-1(-3) = (-3 - 2) / 5
f-1(-3) = -5/5
f-1(-3) = - 1
