i really need help lol

Answer:

-1/6 + 8

Step-by-step explanation:

(1/2x + 2) - (2/3x - 6)

apply distributive property

1/2x + 2 - 2/3x + 6

add like terms. add 1/2x and -2/3x together and then add 2 and 6 together

3/6 + 2 - 4/6 + 6

-1/6 + 8

-1/6 + 8 is your answer. i hope this helps, let me know if i got something wrong :)

Answer:

Hi! The correct answer is y=5+x!

Step-by-step explanation:

~Add x to both sides of the equation~

The solutions are,

8-6a. 110

8-6b. 20

8-6c. 48

8-6d. 108

8-7 C and H are not polygon, the rest are all polygon

The area of the figure is 45 sq.mi and the perimeter is 23.5354 mi.

Area is the space occupied by a two dimensional object,

The area and perimeter of the given shape can be determined by dividing it into basic shapes.

here, we have,

The area and the perimeter of the shape given

= Area of the rectangle +Area of upper triangle - Area of two small triangles at the bottom

Area of rectangle = 5 mi * 9 mi = 45 sq.mi

Area of upper Triangle = (1/2) *9*3 = 27/2 sq.mi

Area of small Triangle = (1/2) * 3*6 = 9 sq.mi

Area of other small Triangle = (1/2)*3*3 = 9/2 sq.mi

Area of the figure = 45 +13.5 -9-4.5

Area of the figure =  45 sq.mi

Similarly for Perimeter = Perimeter of the rectangle +Perimeter of upper triangle -Perimeter of two small triangles at the bottom

Perimeter = 28 -(3+6+6.708) -(3+3+4.2426) +(3+9+9.486

Perimeter = 23.5354 mi

Therefore , The area of the figure is 45 sq.mi and the perimeter is 23.5354 mi.

Answer:

Step-by-step explanation:

There will be one unique solution of the equation y = 5x - 1 and y = 3x + 7. The correct option is B.

A finite collection of equations for which we searched for common solutions is referred to in mathematics as a system of equations, sometimes known as a set of simultaneous equations or an equation system. Similar to single equations, a system of equations can be categorized.

A linear equation can only have one unique solution, which is a location at which the LHS and RHS of the equation are equal. There is only ever one solution to a linear equation with one variable.

y = 5x - 1

y = 3x + 7

5x - 1 = 3x + 7

2x = 8

x = 4

y = 19

Therefore, there will be one unique solution of the equation y = 5x - 1 and y = 3x + 7.

Answer:

slope = - 4

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 3 = - 4(x - 5) ← is in point- slope form

with slope m = - 4

Answer:

-4

Step-by-step explanation:

First express it in the form of y=mx+b where m is the slope and b is the y-intercept

y-3=-4x+20

y=-4x+20+3

y=-4x+23 then m=-4 which is the slope

Answer:

Were they both 45? I'm kinda confused on that part, but I think Ralph would be 48 and Bob would be 50

Step-by-step explanation:

Answer:

34 and 17

Step-by-step explanation:

Bob = B

Ralph = R

B=2R

B-3+R-3=45

B+R-6=45

+6         +6

B+R=51

Substitute B for 2R

2R+R=51

3R=51

R=17

2(17)=34

so B is 34 and R is 17
