Answer:

x = 7

Step-by-step explanation:

4x - 2(x + 3) = 8

4x - 2x - 6 = 8

2x - 6 = 8

2x = 14

x = 7

First step is to distribute -2 to x and 3, which equals -2x and -6

Second step is to subtract 4x - 2x, which equals 2x

Third step is to add -6 to 8, which equals 14

last step is to divide, 2x / 14, which equals 7

I hope this is correct

A mother gives birth to a 9 pound baby. every 4 months, the baby gained 2 pounds. if x is the age of the baby in months, then y
chubhunter [2.5K]
For the equation of the line of the form y = mx + b, m is the slope of the line and b is the y-intercept which is the value of y when x is equal to zero. The slope is the rate of change of y per change in x. "y" would represent the dependent variable which is the weight of the baby while "x" represents the independent variable which is the number of months or the age of the baby in months. We calculate the slope as follows:

slope = (11 - 9) / ( 4 - 0) = 2/4 = 0.5
at x = 0, it is said that the weight of the baby is 9 lbs so the value of b would be 9.

The equation of the line would be y = 0.5x + 9

Which expression results from using the distributive property 2(5 + r)
Vinvika [58]
Using the distributive property we know we distribute by multiplying the outside values to those inside of the parentheses

outside values: 2

inside values: 5 and r

now multiply out inside values by the outside values

2x5 = 10

2xr = 2r

now plug these values back in for the inside values and take away the outside value and the parentheses

so 2(5+r) using the distribution property is 10+2r

Use the elimination method to solve the system of equations. Choose the
hichkok12 [17]

Answer:

the ordered pair is (2,-1)

Step-by-step explanation:

We need to solve the system of equations using elimination method

12x - y = 25     eq(1)

9x + y = 17      eq(2)

Adding eq(1) and eq(2)

12x - y = 25

9x + y = 17

___________

21x = 42

x = 42/21

x= 2

Now, putting value of x in equation 1

12x - y = 25

12(2) -y = 25

24 -y = 25

Adding -24 on both sides

24 -y-24 = 25-24

-y = 25-24

-y = 1

Multiply both sides by -1

y = -1

the value of x = 2 and y = -1

So, the ordered pair is (2,-1)

The base of a right rectangular prism has an area of 173.6 square centimeters and a height of 9 centimeters. What is the volume,
Ivenika [448]

Answer:

hope this helps

Step-by-step explanation:

We are given the an area of

173.6 cm

and a height of 9 cm.

We also know that the formula for area is lw, meaning we can substitute the area for lw

in the volume formula.

Now let's plug in what we know into the formula and solve for the volume:

V=(173.6 cm2)(9 c)=1562.4 cm3 The volume of the rectangular prism is

1562.4 cm3

.

HELP. SUPER EASY MATH PROBLEM. 20 POINTS
Stells [14]

First find the area of the sector of 150 degrees:

150/360 x PI * 27.8^2 = 1011.6452 in^2

Now find the area of the triangle formed by the 150 degrees and the radius 27.8

first find the length of the chord ( the base of the triangle)

c^2 = 27.8^2 + 27.8^2 - 2 * 27.8 * cos(150) = 53.71

now find the height by using half the chord length as the base and using the Pythagorean theorem:

26.855^2 - 27.8^2 = height^2

height = 7.19

The area of the triangle is 1/2 x base x height = 1/2 x 26.855 x 7.1952 = 96.605

multiply by 2 because we made 2 right triangles: 96.54 x 2 = 193.21 square inches.

Now the area of the shaded region is the area of the sector minus the area of the triangle:

1011.6452 - 193.21 = 818.4352

Rounded to nearest tenth = 818.4 in^2
