Given that 5x - 8y = 33 find x when y = 1
fenix001 [56]

Answer:

<h3><u>x = ⁴¹⁄₅ or 8.2</u></h3>

Explanation:

5x - 8y = 33

y = 1

<em>Insert 1 for 'y' in the equation</em>

5x - 8(1) = 33

<em>Remove parenthesis: (a) = a</em>

5x - 8 · 1 = 33

<em>Multiply 8 · 1: 8</em>

5x - 8 = 33

<em>Add 8 to both sides</em>

5x - 8 + 8 = 33 + 8

Simplify

5x = 41

<em>Divide both sides by 5</em>

5x / 5 = 41 / 5

x = ⁴¹⁄₅

<em>Turn the fraction into a decimal</em>

x = 8.2

A sawmill runs for three 4-hour shifts per day. It produces 500 2x4's per hour, which are divided into 50 piece bundles automatc
atroni [7]
It produces 500 per hour and those are divided into 50 piece bundles. so if we divide by 50 we will see how many bundles.
500/50 = 10.

it says that he does 10 bundles an hour and we found it makes 10 bundles per hour so it will take him the exact amount of hours that they run to load.the bundles.

it runs 3 shifts that are 4 hours. so to get the hours we can multiply 3 shifts by 4 hours
3 * 4 = 12 hours

if it did not.match we.could have kept going like this


so 10 bundles per hour for 12 hours is
10 * 12 = 120 bundles

he runs 10 bundles in an hour so we can divide the total by the amount per hour and gwr.how long it takes
120 / 10 = 12 hours

The table lists the heights (in centimeters) of preschool girls and boys on a playground. Heights of Preschool Boys (centimeters
Stells [14]

Answer:

B. The difference of the medians is about one-fourth the interquartile range of either data set

Step-by-step explanation:

Given the heights of preschool boys in cms

105.1 104.8 101.3 87 86.7 95 93.8 92.1 92.4 100

Arrange them in ascending order

86.7 87 92.1 92.4 93.8 95 100 101.3 104.8 105.1

Median = 93.8: Q1 = 87:Q3=101.3

IQR = Q3-Q1 = 4.3

Given the heights of preschool girls in cms

 85.2 90.3 99.6 98.6 97.5 101.7 102.9 89.4 107 92

Arrange them in ascending order

 85.2 89.4 90.3 92 97.5 98.6 99.6 101.7 102.9 107

Median = 97.5: Q1 = 89.4:Q3=101.7

IQR = 4.2

Differnce in the medians = 3.7

Diff in IQR = 0.1

B. The difference of the medians is about one-fourth the interquartile range of either data set because

0.4 = 4(0.1)
