Answer:

n=13/7

Step-by-step explanation:

2n+4+6*2=-9*2+8(2n+1)

2n+4+12=-18+16n+8

16+18=16n-2n+8

34=14n+8

34-8=14n

26=14n

Answer:

n = 13/7

Step-by-step explanation:

Solve the equation

Step 1: Use distributive property to multiply out the terms with parenthesis

(1/2)(2n) + (1/2)(4) + 6 = -9 + 4(2n) + 4(1)

n + 2 + 6 = 9 + 8n + 4

Step 2: combine like terms...

n + 8 = 8n - 5

Step 3: Get all "n's" to one side, and all constants on the other and solve

13 = 7n (subtract n from both sides and add 5 to both sides)

13/7 = n (divide both side by 7)

A rectangular piece of land has an area of 3/4 square mile. The land is 21/2 mile. What is its width

OleMash [197]

Answer:

The width of the rectangle is $\frac{1}{14}$ miles

Step-by-step explanation:

Given as for rectangle

The area of rectangle = A = $\frac{3}{4}$ mile²

The Length of rectangle = L = $\frac{21}{2}$ mile

Let The width of rectangle = W miles

Now, From area of rectangle

I.e Area of Rectangle = Length × Width

Or , A = $\frac{21}{2}$ mile × W mile

Or, $\frac{3}{4}$ mile² = $\frac{21}{2}$ mile × W mile

or, W = $\frac{\frac{3}{4}}{\frac{21}{2}}$ mile

or, W = $\frac{3\times 2}{4\times 21}$

∴ W = $\frac{1}{14}$ miles

Hence The width of the rectangle is $\frac{1}{14}$ miles Answer

erma4kov [3.2K]

Answer:

within-groups

Step-by-step explanation:

According to my research on the scientific method, I can say that based on the information provided within the question the independent variable is being manipulated within groups, because she is not using a pretest and her design is within-groups. This is because she is using the posttest-only control group design which is a research design where at least two groups, one of which does not receive a treatment or intervention, and data is collected on the outcome measure after the treatment or intervention.
