Negative 1X minus 4X equals -4 minus 4X +4+5
Bond [772]

Answer:

X = - 5

Step-by-step explanation:

The above word problem is mathematically interpreted thus:

-1X - 4X = -4 - 4X + 4 + 5

-5X = - 4 - 4X + 4 + 5

-5X = - 4 - 4X + 9

Collect like terms

-5X + 4X = - 4+ 9

-X = 5

X = - 5

Find each missing length, will giv brainliest + 50 pts
kipiarov [429]

Step-by-step explanation:

1. 18^2 - 10^2 = 324 - 100 = 224

Sqt(224)=14.9666

Approximate = 14.97

2. 100 - 16 = 84

Sqrt 84 = 9.1652

Approximate = 9.17

3. 225 - 49 = 176

Sqrt 176 = 13.2665

Approximate = 13.27

4. 361 - 144 = 217

Sqrt 217 = 14.7309

Approximate = 14.73

A box contains 2 plain pencils and 2 pens. A second box contains 3 color pencils and 5 crayons. One item from each box is chosen
Lapatulllka [165]

Answer:

50% pen first box and 62.5% crayon from second box

Step-by-step explanation:

The first box contains 4 items, 2 of each. This means there are \frac{2}{4} pens. This gives you a \frac{2}{4} chance of picking out a pen. This can be written as 50%.

The second box contains 8 items, 3 color pencils and 5 crayons. This means \frac{5}{8} of the contents are crayons, meaning you have a \frac{5}{8} or 62.5% chance of picking a crayon.

*For working out the percentages, you should convert the fraction to a decimal and then multiply that by 100.

**This content involves fractions, decimals and percentages, as well as basic probability, which you may want to revise. I'm always happy to help!
