Hello, well there are a few ways to write this. Here is one outlook.

Bruce bought three boxes of tiles with the same number of tiles in each.

x = number of tiles

3 = number of boxes

3x = total number of tiles.

Make note, the problem is asking for an expression for how many tiles he used and not the total number of tiles he has. Anyways, the problem then tells us he had to go get 3 more boxes but he used only 2 tiles out of the last box. So he used 2x + 2 tiles We put this together and we have

3x + 2x + 2

5x + 2

Number of tiles Bruce used = 5x + 2

We do the same for Felicia:

She gets 5 boxes, which = 5x. Then she had to go back and just get 5 tiles. So we have:

5x + 5

Number of tiles Felicia used = 5x + 5

Caitlyn needs to solve the equation: 2(3x+1)=3(2-x).

Mila [183]

Step 1:Simplify both sides of the equation.2(3x+1)=3(2−x)(2)(3x)+(2)(1)=(3)(2)+(3)(−x)(Distribute)6x+2=6+−3x6x+2=−3x+6
Step 2: Add 3x to both sides.6x+2+3x=−3x+6+3x9x+2=6
Step 3:Subtract 2 from both sides.9x+2−2=6−29x=4
Step 4:Divide both sides by 9.9x9=49

hope it helps :)

What is a real world situation that can be modeled by the equation 1.25x = 0.75 + 50?

erma4kov [3.2K]

1.25x=1.25 so divided both sides by 1.25 sooo x=1

Trapezoid ABCD is graphed in a coordinate plane.

Ann [662]

Answer:

Step-by-step explanation:

he coordinates of the vertices of the trapezoid ABCD are:

A=(-5,-2)=(xa,ya)→xa=-5, ya=-2

B=(-1,2)=(xb,yb)→xb=-1, yb=2

C=(0,-1)=(xc,yc)→xc=0, yc=-1

D=(-2,-3)=(xd,yd)→xd=-2, yd=-3

yi x(i+1) xi yi xi y(i+1)

-5 -2

(-2)(-1)=2 -1 2 (-5)(2)=-10

(2)(0)=0 0 -1 (-1)(-1)=1

(-1)(-2)=2 -2 -3 (0)(-3)=0

(-3)(-5)=15 -5 -2 (-2)(-2)=4

S1=-10+1+0+4→S1=-5

S2=2+0+2+15→S2=19

Area: A=(1/2) Absolute value (S1-S2)

A=(1/2) Absolute value (-5-19)

A=(1/2) Absolute value (-24)

A=(1/2) (24)

A=24/2

A=12

The area of the trapezoid is 12 square units
