Answer:
<em>x=</em><em>-</em><em>1</em><em>3</em>
Step-by-step explanation:
21-3.5x+14=7-7.5x-24
21+14-3.5x=7-24-7.5x
35-3.5x=-17-7.5x
35+17=3.5x-7.5x
<u>5</u><u>2</u>=<u>-4x</u>
-4. -4
x=-13
Answer:
40 cm and 42 cm
Step-by-step explanation:
Two leg length: x and x+2
x² + (x+2)² = 58²
2x² + 4x + 4 = 3364
2x² + 4x - 3360 = 0
(x+42) (x-40) = 0
leg length is a positive number so x = 40
another leg = 42
Ten is mistakenly written by Tim in question.
Gabriel is making a mixture of compost and soil. In which he wants to mix 2 part compost to 10 parts potting soil. And he wants to end up with ten kilogram
It means compost is 2 pars out of 12 and potting soil is 10 parts out of 12
so, (2 / 12) x 10 kilogram of compost is used
= 1.66667 kilogram of compost Gabriel should use.
Answer:
Step-by-step explanation:
p and h are number of plumbers and helpers, respectively.
Twenty workers earn a total of $2600
p+h = 20
h = 20-p
160p + 100h = 2600
160p + 100(20-p) = 2600
60p = 600
p = 10
h = 20-p = 10
Ten plumbers and ten helpers.
