PLZ HELP ME ON ALGEBRA I WILL GIVE 100 POINTS AND BRAINLIEST!

Answer:

See below

Step-by-step explanation:

Part 1:

= 3x - 2

Given that x = 7

= 3(7) - 2

= 21 - 2

[tex]\boxed{= \ 19}[/tex]

Part 2:

= 3x + 7

3 => Coefficient

x => variable

[tex]\boxed{7 => constant}[/tex]

Part 3:

More than => +

So,

The expression is:

= 12 + b

[tex]\rule[225]{225}{2}[/tex]

Hope this helped!

Answer:

A: |x - 6| ≤ 6

Step-by-step explanation:

Looking at the number line graph to interpret the inequality, since the plot is between -6 and 6, the mid value will be (-6 + 6)/2 = 0. Thus, we have;

0 - 6 < x - 6 < 6 - 0

This gives;

-6 < x - 6 < 6

Thus, writing in absolute value, we have;

|x - 6| ≤ 6

Correct Questions:

The correct question has a diagram attached to it which has dimensions of the bedroom floor available which are 15 by 18 feet.

Answer:

Answer is 540 $

Step-by-step explanation:

We will first find the area of the room

Area = Length x Width

Area = 15 x 18 = 270 sq feet

She needs 270 square feet of carpet.

one square feet costs 2 $

so, total cost of carpet = 270 x 2 = 540 $

Answer:

132.

Step-by-step explanation:

If 12% are sold then 100-12 = 88% are unsold.

12% = 18 oranges

1%   =  18/12 = 1.5 oranges,

88% = 1.5 * 88 = 132.

Answer:

1824 in2

Step-by-step explanation:

sqaure = 48 x 32 = 1536 in2

Triangle = (12 x 48) / 2 = 288 in2

total area = 1536 + 288 = 1824 in2

Answer:

[tex]x = 26[/tex]

Step-by-step explanation:

Supplementary Angles add up to 180.

Angle C and Angle D add up to 180.

[tex]128 + 2x = 180[/tex]

[tex]2x = 52[/tex]

[tex]x = 26[/tex]

Answer:

B) 1/4^ 7.

Step-by-step explanation:

You should know this.... basic math

Answer:

[tex]\boxed {\boxed {\sf -0.92}}[/tex]

Step-by-step explanation:

A correlation coefficient is a number ranging from -1 and 1 that measures the strength and direction of a linear relationship.

Since the question only asks for the strongest relationship and does not ask for the direction (positive/negative), we can simply choose the number closest to -1/1. Therefore, the answer is -0.92.

Given:

On a map, the scale shown is 1 inch : 5 miles.

Area of park = 75 square miles.

To find:

The area of the park on the map.

Solution:

Ratio of the areas of similar figures is equal to the ratio square of their corresponding sides.

[tex]\dfrac{\text{Area of park on the map}}{\text{Actual area of the park}}=\dfrac{\text{Side of park in map}^2}{\text{Actual side of park}^2}[/tex]

Let A be the area of the park on the map.

[tex]\dfrac{A}{75}=\dfrac{1^2}{5^2}[/tex]

[tex]A=\dfrac{1}{25}\times 75[/tex]

[tex]A=3[/tex]

Therefore, the area of the park on the map is 3 square inches.

Answer:

a) 3:1

b) yes "si"

c) by enlarging the digram by 150% your bassically tripling the values inside and outside the shape which explains why the new P"Q" is 3 times larger than the smaller one (Translate this)

Answer:

x = 3

Step-by-step explanation:

The axis of symmetry is a vertical line passing through the vertex and midway between the zeros.

The zeros are x = 2 and x = 4

midway = [tex]\frac{2+4}{2}[/tex] = [tex]\frac{6}{2}[/tex] = 3

Equation of axis of symmetry is x = 3

Answer:

350 mph

Step-by-step explanation:

The unit rate here, which is measured in miles per hour (mph) is found by dividing the distance 700 miles by the time period 2 hours:

700 miles

--------------- = 350 mph

  2 hours

Answer:

I'm going to calculate with sides 28 m

4,900 tiles used

Step-by-step explanation:

Area restaurant 28x28 = 784 m squared

each tile 40 cm = 0.4m

area of tile 0.4x0.4 =0.16

784/0.16 = 4,900

Answer:

-3

Step-by-step explanation:

-9u+9u is 0 so all you are left with is -3

Answer:

-3

Step-by-step explanation:

-9u + 9u - 3

-9u and 9u cancel out, so it simplifies to -3

Answer:

10

Step-by-step explanation:

6x = 60

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]

Actually Welcome to the concept of Equilateral triangles.

Since the above triangle is a equilateral triangle, that has all sides equal and also all angles are equal,

by applying the angke sum property of triangle we get as,

==> 6x + 6x + 6x = 180°

hence, 18x = 180°

==> x = 180/18 ==> 10°

hence the value of x = 10°

Answer:

I'm pretty sure it's 0.257!

Sorry if I got it wrong I'm trying my best hope you have a great day!!

Answer:

2.57 is the answer because 1kg=1000g so 2570\1000 ie 2.57 which is 0.257

Answer:

9

Step-by-step explanation:

3/8=x/24 (cross multiplication)

3*24=8x (we don't need to multiply 3 with 24 bc we will divide both sides by 8 so it will be easier to find the final value)

x=9

Answer:

x = 9

Step-by-step explanation:

8: 24

Multiply 3

8 x 3 = 24

3 : x

Multiply 3

3 x 3 = 9

x = 9
