Answer:

13, 14, 15

Step-by-step explanation:

Let x = age of one of the siblings

Since the age of the siblings are consecutive integers, the age of the next sibling would be x + 1 and the age of the third sibling would be x + 2

x +( x +1) + (x +2) = 42

3x + 3 = 42

collect like terms and solve for x

x = 13

The age of the first sibling is 13

The age of the second sibling is x + 1 = 13 + 1 = 14

The age of the third sibling is x + 2 = 13 + 2 = 15

Step-by-step explanation:

x=50 is the solution to the equation -0.20(x– 20) = 44-x. So, option C is correct.

Solution to an equation means that value of the variable for which the equation is satisfied.

Given the following equation:

-0.20(x– 20) = 44-x

A

To check x=-90 is the solution:

Put x=-90 in the given equation

LHS=-0.20(x– 20)

=-0.20(-90-20)

=-0.2(-110)

LHS=22

RHS= 44-x

=44-(-90)

RHS=134

LHS≠RHS

Thus, x=-90 is not the solution.

B

To check x=-50 is the solution:

Put x=-50 in the given equation

LHS=-0.20(x– 20)

=-0.20(-50-20)

=-0.2(-70)

LHS=14

RHS= 44-x

=44-(-50)

RHS=94

LHS≠RHS

Thus, x=-50 is not the solution.

C

To check x=50 is the solution:

Put x=50 in the given equuation

LHS=-0.20(x– 20)

=-0.20(50-20)

=-0.2(30)

LHS=-6

RHS= 44-x

=44-(50)

RHS=-6

LHS=RHS

Thus, x=50 is not the solution.

D

To check x=90 is the solution:

Put x=90 in the given equation

LHS=-0.20(x– 20)

=-0.20(90-20)

=-0.2(70)

LHS=14

RHS= 44-x

=44-(90)

RHS=-54

LHS≠RHS

Thus, x=-90 is not the solution.

Thus x=50 is the solution to the given equation. So, option C is correct.

Answer:

The slope of the lines is 1/3

Step-by-step explanation:

Since I can't graph it, I can make a table

x         y

8        5

2        3

From 5 to 3, you subtract 2 (this is for the y section)

From 8 to 2, you subtract 6 (this is for the x section)

Now all you have to do is divide y by x....

y/x = 2/6 = 1/3 (when simplified)

Answer:

The decimal form of [tex]\frac{1}{15} = 0.0666... = 0.0\overline{666}[/tex].

Step-by-step explanation:

We proceed to find the decimal form of [tex]\frac{1}{15}[/tex], whose description is found below:

1) Multiplying the numerator by 100 and dividing it by 15:

Partial result: 0.06, Remainder: 10

2) Multiplying the remainder by the 10 and dividing it by 15:

Partial result: 0.066, Remainder: 10

3) Multiplying the remainder by the 10 and dividing it by 15:

Partial result: 0.0666, Remainder: 10

Since the decimal number is a infinite and periodical, we conclude that decimal form of [tex]\frac{1}{15} = 0.0666... = 0.0\overline{666}[/tex].

Answer:

The probability that student chose running is [tex]\frac{30}{74}[/tex].

Step-by-step explanation:

Consider the provided information.

74 students choose to attend one of three after-school activities: football, tennis, or running.

16 students choose football,  28 students choose tennis.

The students choose running = 74 - 16 - 28

The students choose running = 30

It means out of 74 students 30 choose running.

[tex]\text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}[/tex]

[tex]\text{Probability of Running}=\frac{30}{74}[/tex]

Hence, the probability that student chose running is [tex]\frac{30}{74}[/tex].

Step-by-step explanation:

Start by grouping the variables (basically reorganizing)

12a - 16a + 26b - 4b

subtract like terms
