Chloe wants to cut a 37 in. piece of ribbon into three pieces. The second piece is to be 2 in. longer than the first, and the th

valentinak56 [21]

1st piece = x

2nd piece = x+2

3rd piece = x+2+3 = x+5

37 = x +x+2 + x+5 =

37 = 3x+7

30=3x

x = 30/3 = 10

1st piece = 10 inches

2nd piece = 10+2 = 12 inches

3rd piece = 10+5 = 15 inches

PLEASE HELP IT WOULD BE VERY MUCH APPRECIATED! Last year, James earned £1,600 per month.

True [87]

Answer: £11.69

Explanation:

1) Work out 2% of £1600:
1600 x 2/100 =36

2) Add it on to the original number to get his new monthly pay:
1600 + 36 = £1636

3) Work out his yearly pay by:

a) finding the amount of months he worked:
46 / 4 = 11.5 months

b) Divide 11.5 into 2 bits and add them on:
1636 x 11 = 17997
1636 x 0.5 = 818

17997 + 818 = £18814

4) To get his pay per week:

18814 / 46 = £409

5) Finally, to get his pay per hour:

409 / 35 = 11.68671...
= £ 11.69

(x - 5)(x + 1)<br> 3(x + 1)<br> For what values of x are the two expressions equal?

Vinvika [58]

Answer:

x = -1 or x = 8

Step-by-step explanation:

Rewrite:

${x}^{2} - 4x - 5 = 3x + 3$

${x}^{2} - 7x - 8 = 0$

$(x - 8)(x + 1) = 0$

$x - 8 = 0$

$x + 1 = 0$

Thus

$x = - 1 \: or \: x = 8$

stepan [7]

Answer:

11.4018 meters

Step-by-step explanation:

The ladder, wall and floor together form a right triangle with the length of the ladder being the hypotenuse, the distance of the foot of the ladder from the wall being one of the shorter sides and the distance between the top of the ladder and the floor being the other side

We can use the Pythagorean theorem to solve for the hypotenuse given the two sides

The general formula is:

$c = \sqrt{a^{2} + b^{2}}$
