Class A has 15 pupils and class B has 29 pupils.

Vaselesa [24]

The mean score (rounded to 2 DP) in the Math's test for class B is 86.86.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Class A has 15 pupils and class B has 29 pupils. The mean score for class A is 55. Hence:

Mean score of A = (sum of all scores) / 15

55 = (sum of all scores) / 15

sum of all scores in A = 825

The mean score for both classes is 76. Hence:

[(sum of all scores in A) + (sum of all scores in B)]/(total number of pupils) = mean score of both classes

[825 + (sum of all scores in B)]/(15 + 29) = 76

sum of all scores in B = 2519

Mean score of B = (2519) / 29 = 86.86

The mean score (rounded to 2 DP) in the Math's test for class B is 86.86.

A rectangular floor measures 10 1/8 feet by 13 3/4 feet. If Emily buys 150 square feet of carpet, will she have enough carpet to

miss Akunina [59]

Yes she will have enough. Here is why.

10 1/8 x 13 3/4 = 139

Therefore the room is 139 square feet. She has 150 square feet of carpet, so she has enough.

On the right side, give a reason to justify each step made on the left

cestrela7 [59]

Given that: step 1

$3x+12=8x-18$

step 2: subtract 3x both side

$\begin{gathered} 3x+12-3x=8x-3x-18 \\ 12=5x-18 \end{gathered}$

Step 3: Add 18 both side:

$\begin{gathered} 12+18=5x-18+18 \\ 30=5x \end{gathered}$

Step 4: divide both side by 5

$\begin{gathered} \frac{30}{5}=\frac{5x}{5} \\ 6=x \end{gathered}$

Find the midpoint of the line segment defined by the points: (5, 4) and (−2, 1) (2.5, 1.5) (3.5, 2.5) (1.5, 2.5) (3.5, 1.5)

Setler79 [48]

Answer:

$\boxed {\boxed {\sf (1.5 , 2.5)}}$

Step-by-step explanation:

The midpoint is the point that bisects a line segment or divides it into 2 equal halves. The formula is essentially finding the average of the 2 points.

$(\frac {x_1+x_2}{2}, \frac {y_1+ y_2}{2})$

In this formula, (x₁, y₁) and (x₂, y₂) are the 2 endpoints of the line segment. For this problem, these are (5,4 ) and (-2, 1).

x₁= 5
y₁= 4
x₂= -2
y₂= 1

Substitute these values into the formula.

$( \frac {5+ -2}{2}, \frac {4+1}{2})$

Solve the numerators.

5+ -2 = 5-2 = 3
4+1 = 5

$( \frac {3}{2}, \frac{5}{2})$

Convert the fractions to decimals.

$(1.5, 2.5)$

The midpoint of the line segment is (1.5 , 2.5)
