Answer:

9x + 36 = 10

Step-by-step explanation:

Given

$\frac{3}{4}$ x + 3 = $\frac{5}{6}$

Multiply by the lowest common multiple of 4 and 6, that is 12

12 × $\frac{3}{4}$ x + 12 × 3 = 12 × $\frac{5}{6}$ , that is

9x + 36 = 10 ← equation without fractions

What is the means-to-MAD ratio of the two data sets, expressed as a decimal to the nearest tenth? Data Set 1: {85, 83, 90, 70, 8

RoseWind [281]

Here is what I got for the first one. MAD= 1/(N)*(|x1-xm|+|x2-xm|+..+|xN-xm|) =1/5(|85-83|+|83-83|+|87-83|+|90-83|+|70-83|) =1/5(2+0+4+7+13)) =5.2 And for the second one I got, MAD= 1/(N)*(|x1-xm|+|x2-xm|+..+|xN-xm|) =1/5(|75-76|+|74-76|+|68-76|+|83-76|+|80-76|) =1/5(1+2+8+7+4)) =4.4

Answer:

Y = 40

Step-by-step explanation:

First, find the slope-intercept of the table

Slope-intercept form: y = mx + b

$m=\frac{y_2-y_1}{x_2-x_1}$

(3, 1) and (6,2)

$m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{2-1}{6-3}\\\\m=\frac{1}{3}$

$y=mx+b$

$y=\frac{1}{3}x+b$

Find b using (6,2):

$y=\frac{1}{3}x+b\\\\2=\frac{1}{3}(6)+b\\\\2=\frac{6}{3}+b\\\\2=2+b\\\\-2\ -2\\\\0=b$

$y=\frac{1}{3}x+b== > y=\frac{1}{3}x+0== > y=\frac{1}{3}x$

$y=\frac{1}{3}x$

What will be the value of Y when X = 120?

Substitute 120 for x into $y=\frac{1}{3}x$

$y=\frac{1}{3}x\\\\y=\frac{1}{3}(120)\\\\y=\frac{120}{3}\\\\y=40$

(120, 40)

Therefore, when X = 120, Y = 40

Hope this helps!

Craig has 36 ounces of flour left in one bag and 64 ounces of flour in another bag. Use the Baking Flour Equivalent table to fin

Ber [7]

So 16 = 3.6, 10 = 2.3 so 20 = 4.6 then add 16 + 20 to get 36 so 3.6 + 4.6 = 8.2
36 ounces = 8.2 cups

36 = 8.2, 8 = 1.8, 20 = 4.6, 36 + 8 + 20 = 64 ounces so 8.2 + 1.8 + 4.6 = 14.6 cups
64 ounces = 14.6 cups

Total cups = 8.2 + 14.6 = 22.8 cups
