Three times the sum of a number and 2 is the same as three-fifths of the sum of the same
number and 22. What is the number?
Answers
Answer:
3
Step-by-step explanation:
3(n+2)=3/5(n+22)
3n+6=3/5n+66/5
3n-3/5n = 66/5 - 6
2.4n = 7.2
n = 7.2/2.4
n = 3
find the distance between the two points rounding to the nearest tenth (4,0) and (0,9)
Answers
Answer:
[tex]\boxed {\boxed {\sf 9.8}}[/tex]
Step-by-step explanation:
We are asked to find the distance between two points. We will calculate the distance using the following formula;
[tex]d= \sqrt {(x_2-x_1)^2+(y_2-y_1)^2[/tex]
In this formula, (x₁ , y₁) and (x₂ , y₂) are the 2 points. We are given the points (4,0) and (0,9). If we match the value and the corresponding variable, we see that:
x₁= 4 y₁= 0 x₂= 0 y₂= 9Substitute the values into the formula.
[tex]{d= \sqrt {(0-4)^2+(9-0)^2[/tex]
Solve inside the parentheses.
(0-4)= -4 (9-0)= 9[tex]d=\sqrt{(-4)^2+ (9)^2[/tex]
Solve the exponents. Remember that squaring a number is the same as multiplying it by itself.
(-4)²= -4*-4= 16 (9)²= 9*9= 81[tex]d= \sqrt{(16)+(81)[/tex]
Add.
[tex]d= \sqrt{97[/tex]
Take the square root of the number.
[tex]d=9.848857802[/tex]
Round to the nearest tenth. The 4 in the hundredth place tells us to leave the 8 in the tenth place.
[tex]d\approx 9.8[/tex]
The distance between the two points (4,0) and (0,9) is approximately 9.8

A student says that if 5x2 = 20, then x must be
equal to 2. Do
you agree or disagree with the
student? Justify your answer.
Answers
Answer:
I agree with the student's answer. "x" cannot be -2 because then it would make -20 which is not equal to 20:
5(-2)(2) = ?
-10 x 2 = ?
? = -20
-20 ≠ 20
Step-by-step explanation:
Justificaiton:
5(x)(2) = 20
10(x) = 20
10/10(x) = 20/10
x = 2
Second Justification:
5(x)(2) = 20
5/5(x)(2) = 20/5
2x = 4
2x/2 = 4/2
x = 2

for f(x) evaluate each of the following:
a. f(0)
b. f(6)
show all your work
Answers
Answer:
Step-by-step explanation:
a)
f(0) is just the function f(x) evaluated at 0, meaning we need to plug in 0 to the function.
What piece of this function should we plug 0 in? Well, because 0 is less than 5, plug it into the first piece.
so f(0) = 0 + 4 = 5
b)
By similar reasoning:
f(6) = 8
because 5 <= 6 < 7

The pie chart below shows the Estrada family’s distribution of the monthly expenses for the last month. The Estrada family spent $366 on clothing last month.
What were the total expenses of the Estrada family last month?
Answers
Pie charts are used to show the relationship between data in a circle. The total expenses of the Estrada family last month are: $2287.5
Given that:
[tex]Clothing = \$366[/tex]
From the Pie chart, 13% of the total expenses were spent on clothing.
This means that
[tex]13\% \times Total = Clothing[/tex]
So, we have:
[tex]13\% \times Total = \$366[/tex]
Divide both sides by 13%
[tex]Total = \$366 \div 16\%[/tex]
[tex]Total = \$2287.5[/tex]
Hence, the total expenses are: $2287.5

Find the sum of the even numbers from 1 to 300
a) 14,280
b) 22,650
c) 16,100
d) 15,460
Answers
Answer:
The answer is 22,650
So, option b for you
Step-by-step explanation:
To find the sum of even numbers from 2 to 300, the formula we use is,
N ( N + 1 )
Where N is given by,
N = [( first number + last number)/2] - 1
So here, N = [ (2 + 300 ) / 2 ] - 1 = 150
And hence Sum = 150 * 151 = 22650
Two angles are supplementary. The measure of the larger angle is 36 more than the measure of the smaller angle. Find their measures.
the answers are 72° and 108° but I need help showing my work
Answers
x = smaller angle
x+36 = larger angle, since its 36 degrees more than the smaller angle
The two angles x and x+36 must add to 180 if they are to be supplementary (aka form a straight line)
So this means we can say the following:
(smaller)+(larger) = 180
(x) + (x+36) = 180
2x+36 = 180
2x = 180-36
2x = 144
x = 144/2
x = 72 is the smaller angle
x+36 = 72+36 = 108 is the larger angle
As a check:
smaller+larger = 72+108 = 180
which shows they are supplementary and it confirms our answers
Step-by-step explanation:
let the smaller angle be x
then the measure of larger angle will be x+36
x+x+36=180°(being supplementary angle)
2x+36=180°
2x=180°-36
2x=144°
x=144°/2
x=72°
now,
the larger angle x+36 = 72+36=108°

Answer:
infinite solutionsx = -2Step-by-step explanation:
1. The equation simplifies as follows:
5(x +2) =10 +5x
5x +10 = 5x +10 . . . . . eliminate parentheses, write in standard form
0 = 0 . . . . . . . . . . . . . . subtract 5x+10 from both sides
This is true for all values of x. Any value of x is a solution to this equation. There are an infinite number of solutions.

2. 7/8(48x -8) +4 = 3(5x -19) . . . . given
42x -7 +4 = 15x -57 . . . . . . . . eliminate parentheses
25x = -50 . . . . . . . . . . . . . add 7-15x to both sides
x = -2 . . . . . . . . . . . . . . divide by 25
Check
7/8(48(-2) -8) +4 = 3(5(-2) -19) . . . . substitute for x
7/8(-96 -8) +4 = 3(-10 -19)
7/8(-104) +4 = 3(-29)
