Subsitution is subsituting
y=3x-2
y=-x+6
subsitute 3x-2 for y in second equation
3x-2=-x+6
add x to both sides
4x-2=6
add 2 to both sides
4x=8
divide both sides by 4
x=2
subsitute
y=-x+6
y=-2+6
y=4

x=2
y=4

The surface area of a cuboid is 102 cm2. If its length is 2 cm and its breadth is 3 cm, find its height.
Anna11 [10]

Answer:

Height h = 9 cm

Step-by-step explanation:

Surface area of cuboid = 102 cm²

Length l = 2 cm

Breadth b = 3 cm

Find:

Height h

Computation:

Surface area of cuboid = 2[lb + bh + hl]

102 = 2[(2)(3) + (3)(h) + (h)(2)]

51 = 6 + 3h + 2h

45 = 5h

  q - 1/12 = 3/4

  q = 3/4 + 1/12 = 9/12 + 1/12 = 10/12

  q = 5/6

There was 5/6 of a box before Heba ate.

Answer:

If the rest of the question is:

Each game is a win or a loss.

He wins three fifths of his first 40 games.

He then wins his next 12 games.

For all 52 games, work out the ratio wins : losses

Give your answer in its simplest form.​

then the answer is below ↓

Step-by-step explanation:

9:4

of his first 40 games:     3/5 *40=3*8=24  wins

=> of his first 40 games: 24 wins and  40-24=16 losses

next 12 games: 12 wins

so,  for all  52 games: 24+12=36 wins and 16 losses

36 wins and 16 losses

wins: losses=> 36:16=> 9:4
