Answer:
Step-by-step explanation:
Step 1: Equation at the end of step 1
Simplifying
60(x + 20) = 3x
Reorder the terms:
60(20 + x) = 3x
(20 * 60 + x * 60) = 3x
(1200 + 60x) = 3x
Solving
1200 + 60x = 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
1200 + 60x + -3x = 3x + -3x
Combine like terms: 60x + -3x = 57x
1200 + 57x = 3x + -3x
Combine like terms: 3x + -3x = 0
1200 + 57x = 0
Add '-1200' to each side of the equation.
1200 + -1200 + 57x = 0 + -1200
Combine like terms: 1200 + -1200 = 0
0 + 57x = 0 + -1200
57x = 0 + -1200
Combine like terms: 0 + -1200 = -1200
57x = -1200
Divide each side by '57'.
x = -21.05263158
Simplifying
x = -21.05263158

What is the slope of the following line?
A. 1/3
B. - 1/3
C. 3
D. - 3
Answer:
A
Step-by-step explanation:
Points of origin are (-3,0) and (0,1). Now we determine if it is a positive slope, it is as it goes up not down. It goes up 1 unit and over to the right 3 units, making the slope 1/3.

Please help me with this one!
Answer:
x = 2
Step-by-step explanation:
Since the triangles are similar then corresponding sides are in proportion, that is
[tex]\frac{AB}{DE}[/tex] = [tex]\frac{BC}{EF}[/tex] , substitute values
[tex]\frac{7x}{7}[/tex] = [tex]\frac{4}{x}[/tex] ( cross- multiply )
7x² = 28 ( divide both sides by 7 )
x² = 4 ( take square root of both sides )
x = [tex]\sqrt{4}[/tex] = 2

2,631 dividido entre 24
Answer:
2631 divided by 24 = 109.625
Step-by-step explanation:
The result of 2631/24 is a terminating decimal with 3 digits to the right of the decimal point.
2631 divided by 24 in decimal = 109.625
2631 divided by 24 in fraction = 2631/24
2631 divided by 24 in percentage = 10962.5%
Note that you may use our state-of-the-art calculator above to obtain the quotient of any two integers or decimals, including 2631 and 24, of course.
Repetends, if any, are denoted in ().
The conversion is done automatically once the nominator, e.g. 2631, and the denominator, e.g. 24, have been inserted.

Someone help meee?
This is soo hard
Answer:
100
Step-by-step explanation:
angles CHF and EHI are congruent angles because CD is a straight line.
Therefore EHI must be 20 degrees.
angles DIG and EIH are congruent angles because CD is a straight line.
Therefore EIH must be 60 degrees.
Now that you know two of the three angles in the triangle HEI,
Total degrees in a triangle - EIH - EHI = HEI
180 - 60 - 20 = 100
is the answer C, E, A, B, or D?
Answer:
the answer is B hope this helps

in 2000 the population of India was around 1.053 billion , and in 2016 the population hit 1.327 billion people . if India's population continues to grow at this same rate in what year was the population of India reach 3 billion people.
Answer:
The population of India would reach 3 billion in about 112 years (year 2128)
Step-by-step explanation:
1. subtract 1.327 billion by 1.053 billion (1.327-1.053)
2. The answer you should get is 274,000,000 (two hundred seventy four million)
3. multiply 274,000,000 by 7 (amount of people required to reach about 3 billion)
4. add the product (ans to multiplication problem) to 1.327 billion. (you should get 3.245 billion (3245000000).
5. multiply 16 by 7 (16x7) to get the number of years to reach 3 billion (maybe 112)
6. Add the product to 2016
7. Therefore you get the year 2128.
if x 60 and 30 find the unknown sizes of angle
Answer:
A special right triangle is a right triangle having angles of 30, 60, 90, or 45, 45, 90. Knowledge of the ratio of the length of sides of a special right triangle enables us to solve for any missing part of the triangle. The ratio of the side lengths of a special right triangle with angles of 30, 60, 90 is 1:sqrt(3):2, while the ratio of the side lengths of a special right triangle with angles of 45, 45, 90 is 1:1:sqrt(2).
