Answer:
h = [tex]\frac{c}{b-h}[/tex]
Step-by-step explanation:
Given
ba - ha = c ← factor out a from each term on the left side
a(b - h) = c ← divide both sides by (b - h)
a = [tex]\frac{c}{b-h}[/tex]

A book is on sale for 30% off. The sale price of the book is $14. What is the original price of the book
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!

Step-by-step explanation:
30j+40% + 25j= 562.8
30j+25j= 55j
55j + 40% = 562.8
40% of 55 is 22
77j = 562.8

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
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.

What is f(3) in the graph below?*
Answer:
(3, 2)
Step-by-step explanation:
If person a and person b go fishing and both catch fish. If person a gives half their fish to person b and then they have equal amounts. How many fish does each have
Answer:
The number of fishes person b initially has is 0
The number of fishes person a initially has is x, where x is any natural number
Step-by-step explanation:
The given parameters are;
let x represent the number of fish person a catches and let y represent the number of fishes that person b catches, we have;
x - x/2 = y + x/2
2·x - x = 2·y + x
2·x = 2·y + 2·x
∴ y = 0
Therefore;
The number of fishes person b initially has = 0
The number of fishes person a initially has = x, where x is any natural number.

Solve for x: 7 + 4x = 13+ X. Select one: a. x = 1 1/5 b.x=2 x 2 C. X= 4 d. x = 6 2/3
Answer:
7+4x=13+x
4x-x=13-7
3x=6
3 3
x =2
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
What is the common difference in the arithmetic sequence 5.0, 4.5, 4.0, 3.5
Answer:
0.5
Step-by-step explanation:
Look at the decimal go down. It goes down 0.5 each time or 1/2
The common difference in the arithmetic sequence 5.0, 4.5, 4.0, 3.5 will be 0.5.
What is the arithmetic sequence?Let a₁ be the first term and d is the common difference between the terms. Then the nth term will be given as
[tex]\rm a_n = a_1 + (n - 1)d[/tex]
The arithmetic sequence is given below.
5.0, 4.5, 4.0, 3.5
Then the common difference will be
d = 5.0 – 4.5 = 0.5

Write a paragraph to proof to show that if <1 and <2 are congruent supplementary angles, then <1 and <2 are right angles
Answer:
see below
Step-by-step explanation:
we know that
[tex]\angle 1 =\angle 2[/tex]
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]
so there we have it
[tex]\angle 1 = 90 =\angle 2[/tex]
(73 points) Find the value of x.
Answer:
Option C. [tex]98^{\circ}[/tex]
Step-by-step explanation:
[tex]\angle DAB + \angle BAC = 180[/tex] (the two angles sum to the angle of a straight line: [tex]180^{\circ}[/tex])
[tex]122+\angle BAC = 180[/tex]
[tex]\angle BAC = 180-122[/tex]
[tex]=58^{\circ}[/tex]
[tex]24+58+x = 180[/tex] (sum of interior angles of triangle is [tex]180^{\circ}[/tex])
[tex]82+x=180[/tex]
[tex]x=98^{\circ}[/tex]
∴ Option C is correct.
