Answer:
Number is 19
Step-by-step explanation:
denote the number by x.
the line says:
5x - 20 = 18 + 3 x
Subtracting 3x form both sides
2x - 20 = 18
adding 20 to both sides
2x = 38
dividing both sides by 2
x = 19
Answer:
19
Step-by-step explanation:
let n = the number
5n - 20 = 18 + 3n
combine like terms in one of four different ways
2n = 38
n = 19

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]

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).
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

Answer: $7.31
Step-by-step explanation:
30j+40% + 25j= 562.8
30j+25j= 55j
55j + 40% = 562.8
40% of 55 is 22
77j = 562.8
562.8 77 = 7.309090909.....

find a number that is exactly halfway between 1 and 27
Answer:
14
Step-by-step explanation:
A number that is exactly halfway between 1 and 27 is the middle number
In other words, we want to find the median between 1 and 27
Median = (x + y) / 2
Let
x = 1
y = 27
Median = (x + y) / 2
= (1 + 27) / 2
= 28/2
= 14
Therefore, the number between 1 and 27 is 14

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

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!

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.

Answer:
[tex]\frac{1}{cos^2a }= tan^2 a[/tex]
Step-by-step explanation:
Explanation:-
Given sin²a + cos²a = 1
and
[tex]\frac{1}{cos^{2} a} \\= \frac{sin^2a+cos^2a}{cos^2a} \\ \\\\ = \frac{sin^2a}{cos^2a} +\frac{cos^2a}{cos^2a}[/tex]
= tan²a + 1
