What is the answer to 4(m+3)=18
konstantin123 [22]

Answer:

M = 1.5

Step-by-step explanation:

First, apply the distributive property to the problem. For this, you will multiply 4 x m, then 4 x 3.

Now, your problem looks like

4m + 12 = 18

Next, you need to get the variable isolated. For this, you need to subtract 12 from both sides.

Now, your problem looks like

4m = 6

Next, you can divide both sides by the non-constant term, which is 4m, so divide by 4.

Now, your problem looks like

M = 1.5

Shawna, Dexter, and Tilana are solving the equation Negative 2. 5 (5 minus n) 2 = 15. Shawna says, "I can begin by dividing each
aleksandrvk [35]

Shawana, Dexter, and Tilana are correct.

<h2>Given that</h2>

Equation: \rm  -2.5(5 - n) + 2 = 15&#10;&#10;&#10;

<h3>We have to determine</h3>

Which students are correct?

<h3>According to the question</h3><h3>Equation: \rm  -2.5(5 - n) + 2 = 15&#10;&#10;&#10;</h3>

The correct way to solve the equation is;

SHAWNA

Statement: Dividing each side of the equation by –2.5,

\rm  \dfrac{-2.5(5 - n) + 2 }{-2.5}= \dfrac{15}{-2.5}\\&#10;\\&#10;(5-n) - \dfrac{2}{2.5} =  \dfrac{15}{-2.5}\\\\&#10;\\&#10;

Here, Shawna is correct.

DEXTER

Statement: Distributing -2.5 to get -12.5 + 2.5 n + 2 = 15.

\rm -2.5(5-n) +2=15\\&#10;\\&#10;-2.5(5) - 2.5 (-n) +2= 15\\&#10;\\&#10;-12.5 +2.5n +2=15

Hence, Dexter is correct.

" Tirana says, "I can begin by multiplying each side of the equation by Negative Start fraction 1 over 2. 5 End fraction to get 5 minus n minus 0. 8 = negative 6. "

\rm \dfrac{-1}{2.5} (-2.5 (5-n)+2)= \dfrac{-1}{2.5}\times 15\\&#10;\\&#10;(5-n) + \dfrac{-2}{2.5} = \dfrac{-15}{2.25}\\&#10;\\&#10;(5-n) -\dfrac{2}{2.5} = \dfrac{-15}{2.5}\\&#10;\\&#10;5-n-0.8=-6

Hence, Tilana is also correct.

Hence, Shawana, Dexter and Tilana are correct.

Identify the lower quartile (Q1), the median (Q2), and the upper quartile (Q3) for this data set.
Lena [83]
{1, 2, 4, 5, 7, 7, 8, 9, 9, 10}

Lower Quartile: Q₁ = ¹/₄(n + 1)
                          Q₁ = ¹/₄(10 + 1)
                          Q₁ = ¹/₄(11)
                          Q₁ = 2³/₄

Median: Q₂ = ¹/₂(n + 1)
              Q₂ = ¹/₂(10 + 1)
              Q₂ = ¹/₂(11)
              Q₂ = 5¹/₂

Upper Quartile: Q₃ = ³/₄(n + 1)
                          Q₃ = ³/₄(10 + 1)
                          Q₃ = ³/₄(11)
                          Q₃ = 8¹/₄

Q₁ = 2³/₄
Q₂ = 5¹/₂
Q₃ = 8¹/₄
