Step-by-step explanation:
x+4 = 4x -20
3x= 24
x=8
plz brainliest :)
Let the number is 'x'
So the four times of this number will be 4x
And twenty less than from this number is
4x-20
According to question
4x-20=4
=> 4x=4+20
=> 4x=24
=> x=24/4
=> x=6
So the number is 6
describe how to solve -5x=30
Answer:
x = -6
Step-by-step explanation:
30 = -5x

Answer:
Divide both sides by -5.
x = 30/-5 = -6
x = -6

Find the unknown value in the proportion x∕32 = 38∕64.
Question 4 options:
A)
19
B)
38
C)
54
D)
76
Answer:
x=19
Step-by-step explanation:
This can be found in two ways.
Way #1
Since 32 is half of 64, divide 38 in half to get the missing number, or 19.
Way #2
Solve for x.
x/32 = 38/64
(Solve the expression on the right side)
x/32 = 0.59
(Multiply both sides by 32 to isolate the variable.)
x= 18.88 --> 19.

2. in a class of 50 students, the number of females is 2 more than 5 times the number of males. How many males and females are there in the class?
Answer:
The number of male students is 8, while the number of female students is 42.
Step-by-step explanation:
To determine the number of male and female students in the class, knowing that in total there are 50 students, and that the number of female students is two more than five times the number of male students, the following equation must be performed:
X + (5X + 2) = 50
6X + 2 = 50
6X = 50 - 2
X = 48/6
X = 8
Thus, the number of male students is 8, while the number of female students is 42.
C.is decrease by 1 foot every 500 miles D. Is decrease by 1 foot every 1000 miles
Answer:
Option A
Step-by-step explanation:
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Line shown in the graph is passing through two points (2, 8000) and (4, 7000).
Therefore, slope of the given line = [tex]\frac{8000-7000}{2-4}[/tex]
= -500 feet per mile
Which means, altitude decreases by 500 ft every mile.
(Negative sign represents the decrease)
Option A is the correct option.
One leg of a right triangle measures 10 inches while the other leg measure square root of 21 inches. What is the length of its hypotenuse?
Answer:
11 inches
Step-by-step explanation:
hypotenuse² = leg₁² + leg₂²
=10² + (√21)²
= 100 + 21
= 121
Hypotenuse = √ 121 = √11*11 = 11 inches
Answer:
10^2+√21^2= 100+21= 121
square root of 121= 11
Answer is 11 inches

h) There are 5 significant numbers in 0.0087600
i) There are 3 significant numbers in 0.00202
Step-by-step explanation:
How many significant figures are in each of these numbers?
a) 768
There is no decimal so, all digits are significant numbers.
There are 3 significant numbers in 768
b) 0.000086
There is decimal point in this number. Zero's on leading (right) side of the number are not considered significant. Only non-zero values are considered significant.
So, There are 2 significant numbers in 0.000086
c) 8.0
There is decimal point in this number. Digits on left side and right side of the decimal are considered significant
So, There are 2 significant numbers in 8.0
d) 43,000
There is no decimal so, all digits are significant numbers.
There are 5 significant numbers in 43,000
e) 3.0200x10^6
It can be written as: 3.0200000000
There is decimal point in this number. Digits on left side and right side of the decimal are considered significant
So, There are 11 significant numbers in 3.0200x10^6
f) 7.9800
There is decimal point in this number. Digits on left side and right side of the decimal are considered significant
So, There are 5 significant numbers in 7.9800
g) 98.0010
There is decimal point in this number. Digits on left side and right side of the decimal are considered significant
So, There are 6 significant numbers in 98.0010
h) 0.0087600
There is decimal point in this number. Zero's on leading (right) side of the number are not considered significant. Only non-zero values are considered significant.
So, There are 5 significant numbers in 0.0087600
i) 0.00202
There is decimal point in this number. Zero's on leading (right) side of the number are not considered significant. Only non-zero values are considered significant.
So, There are 3 significant numbers in 0.00202
