Congruent= the same shape and size.

area of the rectangle before it is divided=8*(area congruent rectangle)
area of the rectangle before it is dividide=8*(5 cm²)=40 cm²

Area of the rectangle before it is dividide=40 cm²

Work out how many litres of water she saves by having a shower instead of a bath
Ber [7]
Water used for shower = 10.6 x 7 = 74.2 liters

Water used for bath = 35 x 120 x 40 = 168 000 cm³ = 168 liters

Difference = 168 - 74.2 = 93.8 liters.

Answer: She saved 93.8 liters of water by showering instead of taking a bath.

Solve for x<br> And show work
klemol [59]

Answer:

x = -8

Step-by-step explanation:

1. Because the line the angles x + 96 and 100 + x are on is straight, it's a straight angle that results in 180°.

2. Given the above information, that means x + 96 + 100 + x = 180.

3. (Solving for equation above)

Step 1: Simplify both sides of the equation.

  • (x+x) + (96+100)=180
  • 2x + 196 = 180

Step 2: Subtract 196 from both sides.

  • 2x + 196 - 196 = 180 - 196
  • 2x = -16

Step 3: Divide both sides by 2.

  • \frac{2x}{2} = \frac{-16}{2}
  • x = -8

Step 4: Check if solution is correct.

  • -8 + 96 + 100 - 8 = 180
  • 88 + 100 - 8 = 180
  • 188-8=180
  • 180=180

Therefore, x = -8.

Graph by using the slope and the y intercept.
Mashutka [201]

1. a) equation of the line :

  • y =  \dfrac{2}{5}x   - 7

y - intercept = -7

so, it will pass through point (0, -7)

and if we plug the value of x as 5, we get

  • y =  (\dfrac{2}{5}  \times 5) - 7

  • y = 2 - 7

  • =  - 5

so, it will pass through point (5, -5) too

now, just plot the points (0 , -7) and (5 , -5) and join them.

2. b) equation of line is :

  • y =  - 3x + 5

here, y - intercept = 5

so the line passes through point (0 , 5)

now, Plugging the value of x = 1 we get :

  • y =(  - 3 \times 1) + 5

  • y =  - 3 + 5

  • y = 2

so, the given line passes through point (1 , 2)

plotting the points, we can get our required line.
