A fruit company delivers its fruit in two types of boxes: large and small. a delivery of 5 large boxes and 3 small boxes has a t

Hoochie [10]

Let's let the weight of a large box be L, and the weight of a small box be S.

We know that 5 large boxes and 3 small boxes is 120kg, so:
5L + 3S = 120

We also know that 7 large boxes and 9 small boxes is 234kg, so:
7L + 9S = 234

You can multiply the first equation by 3 to get:
15L + 9S = 360

See how now both equations have 9S? We can now subtract one from the other:
(15L+9S) - (7L+9S) = 360-234
8L = 126
L = 15.75

Now sub this value back into an equation:
(5x15.75) + 3S = 120
3S = 41.25
S = 13.75

Double check these values
(7x15.75) + (9x13.75)
= 110.25 + 123.75
=234, which is consistent with above.

So a large box is 15.75kg, and a small box is 13.75kg.

Hope this helped

Nonamiya [84]

Answer:

4.9%

Step-by-step explanation:

6600 * 107/100 = 66*107 = 7062.

3500 * 101/100 = 35x101 = 3535

7062+3535=10597. Original worth: 10100

10597-10100 = 497

497/10100 = 0.0492079208, or 4.92%, rounds to 4.9%

22-3= 19
19+2 = 21
21-3= 18

Solve for x.

egoroff_w [7]

∑ Hey, KLPJDP615 ⊃

Answer:

x = 6 or x = -10

Step-by-step explanation:

Given:

Solve for x.

1 + |2+x|= 9

O x = 4 or x = -8

O x = 7 or X = -11

O x = 5 or x = -9

x = 6 or X = -10

Solve:

1 + |2+x|= 9

Subtract 1 from both sides:

1 + |2 +x| -1 = 9-1

Simplify

|2 + x | = 8

Applying absolute value rule: If |u| = a, a > 0 then u = a or u = -a

2 + x = -8

2 + x = 8

Solving:

2 + x = -8

2 - 2 + x = -8 - 2

x = -10

Solving:

2 + x = 8

2 - 2 + x = 8 - 2

x = 6

Hence, x = 6 or x = -10
