 A contractor purchases 6 dozen pairs of padded work gloves for ​$87.12. She incorrectly calculates the unit price as ​$14.52 pe
artcher [175]

So, there are 6 dozen pairs of gloves. That amount of gloves costed $87.12. She calculated the amount per pair as 14.52. This was incorrect because she forgot about the majority of the 6 dozen(one dozen is the number 12). So that means there are not 6 pairs of gloves, in fact, there are 72 pairs of gloves. So, now that we have that number, we can <u>correctly</u> calculate the amount of gloves per pair. Now we have 2 answers. The amount per glove and the amount per pair

Answer 1: Each pair of gloves costs $1.21.

Answer 2: Each individual glove costs 61¢<em>(if there is a number under the hundredths place in the price, like in the thousandths, you </em><em>always</em><em> round upwards, in this case, the cost was .605, but you round up, making it 61¢)</em>

olya-2409 [2.1K]
4x+6 (3x ) - 12 = 4x +6 *3 x - 12 
                          = 4x +18 x - 12
                          = 22 x -12

Find the values of the variables and the measures of the angles
yuradex [85]

Answer:

x = 13

39° and 51°

Step-by-step explanation:

Angles in a triangle add up to 180 degrees.

This is a right angle triangle, so one side has a size of 90 degrees.

3x + 4x - 1 + 90 = 180

7x + 89 = 180

7x = 91

x = 91/7

x = 13

Put x as 13 to work out the size of the angles.

3(13) = 39

4(13) - 1

52 - 1 = 51
