-24a-30. This is so because when you distribute you get numbers with like terms which you can then combine into a "simple" answer.

This is the question
vesna_86 [32]

Hey there!

The answers to your question are C, D, and E

If there are repeats in the X column, then it's not a function. If there are no repeats, then it is! If there are repeats in the Y column, that's ok, but there cannot be repeats in the X column.

Hope this helps! If you need any other help, just tell me!

The mean of six numbers is 45. Four of the numbers are 40, 38, 46, and 51. If the remaining two numbers are I. The ratio of 2:3,
Advocard [28]

Answer:

The numbers are 38 and 57

Step-by-step explanation:

Let

x-----> the missing smaller number

y----> the missing larger number

we know that

45=\frac{40+38+46+51+x+y}{6} \\ \\270=175+x+y

x+y= 95 -----> equation A

\frac{x}{y}=\frac{2}{3}

x=\frac{2}{3}y -----> equation B

substitute equation B in equation A and solve for y

\frac{2}{3}y+y= 95

\frac{5}{3}y= 95

y=95*3/5=57

Find the value of x

x=\frac{2}{3}(57)=38

Which division problem does the model below show? 4 fraction bars. The fraction bars are labeled 1 and each have 6 boxes underne
Ksivusya [100]

Answer:

4 divided by one-sixth = 2

Step-by-step explanation:

Given 4fraction bars

If each fraction bars has 6boxes, then we can get the total boxes for 4fractiom bars as shown;

1 fraction bars = 6boxes

4fraction bars = x

Cross multiply

1 × x = 4×6

x = 4× 6/1

x = 4 ÷ 1/6

Hence the division problem that modelled the expression is 4 ÷ 1/6

4÷1/6 = 4×6/1

4÷1/6 = 24

Option A is correct
