Solve: 7x + 3 + 2x + 13

Answer: Itll always be a rational number and never zero

Step-by-step explanation:

Answer:

A rational number (The third option).

Step-by-step explanation:

1. By definition, rational numbers have the following form, where and are integers and [tex]b\neq 0[/tex].

2. Therefore, when you add two rational numbers, the result will be a rational number.

3. An example is shown below:

[tex]\frac{1}{5}+\frac{2}{5}+\frac{3}{5}[/tex]

The result is a fraction whose numerator and denominator are integers.

Answer: D. SSS

Step-by-step explanation:

The solution would be SSS because the image shows that AB is congruent to DE, BC is congruent to EF, and AC is congruent to DF. Because the image shows that all three sides are congruent to their corresponding side on the other triangle, with no mention of angles, the triangles are congreunt through the SSS theorem.

Answer:

Step-by-step explanation:

Mrs. Chipps buys 30 c + 50 r = $95

Mr. Meehan buys 40 c + 40 r = $116    x (-1.25) to eliminate r

                             30 c + 50 r = $ 95

                            -50 c - 50 r  = $-145

                            -20 c             =  -50

                                               c = 50 / 20

                                               c = $2.5

substitute c = 2.5 into eq. 1

30 c + 50 r = $95

30 (2.5) + 50 r = 95

75 + 50 r = 95

50 r = 95 - 75

r = 20 / 50

r = 0.40

therefore, the individual costs of the compasses and rulers are:

compass = $ 2.50 each

ruler        = $ 0.40 each

Answer:X=3

y= -4

Step-by-step explanation:

If we're solving for x or y, then the intercept we're not solving for is equal to zero. Solving for y means x=0, solving for x means y=0.

so solving for x, 4x=12--> x=3, since y=0 in this scenario.

Solving for y, x=0, so -3y=12--> y=(-4)

9514 1404 393

Answer:

  see below for a table

Step-by-step explanation:

You can easily identify intercept points by solving for one variable when the other is zero.

x-intercept (y=0)

  4x = 12

  x = 12/4 = 3

y-intercept (x=0)

  -3y = 12

  y = 12/-3 = -4

So, the coordinate pairs of these points are ...

  (3, 0) and (0, -4)

__

If you solve for y, you get ...

  -3y = 12 -4x

  y = (4/3)x -4 . . . . . divide by -3

This suggests that x being a multiple of 3 will be useful for finding integer values of y.

We already have points for x=0 and x=3. We can add points for x=6 and x=-3.

  y = 4/3(6) -4 = 4

  y = 4/3(-3) -4 = -8

So, the additional points are ...

  (6, 4) and (-3, -8)

Answer:

k = 3

Step-by-step explanation:

f(x) = 112 - kx   ------------------(I)

f(-3) = 121

In equation (I) substitute x = -3

112 - k*(-3) = 121

112 + 3k = 121

        3k = 121 - 112

        3k = 9

          k = 9/3

k = 3

Answer:

5:14

Step-by-step explanation:

The ratio of adults to children using the form 1:n would look like this:

number of adults : number of children

So:

5 adults : 14 children = 5:14

Answer:

1 : 2.8

Step-by-step explanation:

in such a case what the question is asking you to is to compare the numbers and simplify them with the left hand number.

ratio of adult to children

write it as 5:14

put the 1 :n underneath

5  :  14   what we want to find is the n. among the 2 sides one is complete                      

1   :   n      only whole numbers. to get n look at the complete side . if

                    5:1      14=14 x 1 /5(cross multiplication). or you can

divide both sides by the left hand number(5)

5   and   14   =   1 :  2.8

5              5

the n is what we were trying to find and compare it to 1

this means for every 1 adult there are 2.8 children

Answer:

X intercept = 1/2

(x, y) = (1/2, 0)

Step-by-step explanation:

In order to find the x intercept, plug y = 0

y = - 4x + 2

Plug y = 0

0 = - 4x + 2

4x = 2

x = 2/4

x = 1/2

(x, y) = (1/2, 0)

Answer:

They won't have the same weight during the program

Step-by-step explanation:

Let w = number of weeks

SANDRA:

Starting weight = 150 pounds

Weight lost per week = 1 pound

150 - w

BERNICE:

Starting weight = 135 pounds

Weight lost per week = 0.5 pound

135 - 0.5w

WEEK in which they'll weigh the same :

150 - w = 135 - 0.5w

150 - 135 = - 0.5w + w

15 = 0.5w

w = 15/ 0.5

w = 30

Since the program will last 12 weeks, they'll not have the same weight during the program

Answer:

Sample = 1046

Population = All adults.

Step-by-step explanation:

In Statistics, a sample can be defined as a set of items, objects or individuals collected, selected or drawn from a population. Thus, a sample is a subset of a population. In this scenario, the sample is 1046.

On the other hand, population can be defined as the total number of individuals in a survey. Thus, all the adults are a population.

Answer:

£15.6

Step-by-step explanation:

Method 1:

You are trying to find 30% of £52.

Therefore:

[tex]\frac{30}{100} * 52 = \frac{30 * 52}{100}[/tex]

If you solve this you will find that 30 × 52 = 1560, and 1560 ÷ 100 = £15.6.

So, the answer is £15.6.

Method 2:

You can solve 30% of £52 by using an algebra equation.

By using the rule that to convert a percentage to a decimal you divide by 100, you can change 30% to be 0.3.

Now, in order to write the equation, you will have to include 0.3 and 52.

The equation is:

0.3 * 52 = x

Once you multiply, you will find that the answer is £15.6.

Answer:

x = 10

Step-by-step explanation:

Okay the two sides are going to equal the same measure soo...

4x + 9 = 11x - 61 (Subtract 4x on both sides)

9 = 7x - 61 ( add 61 on both sides)

70 = 7x (divide both sides by 7)

10 = x

The triangles ΔJMK and ΔLMK are congruent. Then the value of the variable 'x' will be 10.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

In triangles ΔJMK and ΔLMK, then we have

∠JMK = ∠LMK = 90°          (Right angle)

∠JKM = ∠LKM                    (Given)

KM = KM                             (Common side)

The triangles ΔJMK and ΔLMK are congruent with each other. Then the sides JK and KL will be equal. Then the value of 'x' will be given as,

KL = JK

11x - 61 = 4x + 9

11x - 4x = 61 + 9

7x = 70

x = 70 / 7

x = 10

The triangles ΔJMK and ΔLMK are congruent. Then the value of the variable 'x' will be 10.
