Answer:
C, D and E
Step-by-step explanation:
Given
Represent solid beads with S and clear beads with C
So:

Required
Select operations that give an equivalent ratio
First, we need to get the unit ratio

Divide through by 4
-- This means that, after any operation. The equivalent ratio must be 2: 5
Option A: Add 2 to S and 2 to C

Perform the operation


Divide through by 2

Option B: Subtract 8 from S and 6 from C

Perform the operation


Option C: Multiply S and C by 2

Perform the operation


Divide through by 8

Option D: Divide S and C by 4

Perform the operation


Option E: Multiply S and C by 18

Perform the operation


Divide through by 72


<em>From the calculations above, options C, D and E gave an equivalent of 2:5.</em>
Answer:
10(q-3)
last option
please brainliest me btw
Step-by-step explanation:
The expression states 10q-30
The GCF is 10 (30 GCF by 10 Is 10)
Factor out 10
After, divide all the terms by 10
10 (10q/10) - 30/10
Simplify this and we get
10(q-3)
so in conclusion, it is the last option.
Answer:
sorry i do not know
Step-by-step explanation:
F(x)=3-2x
g(x)=(1/x)+5
(f/g)(8)
f(8)=3-2(8)
f(8)=3-16
f(8)=-13
g(8)=(1/8)+5
g(8)=5.125, or 41/8
(f/g)(8)=(-13)/(41/8)
(f/g)(8)=-104/41, or -2.536585366
Number of pieces of chalk that are yellow is 6
<h3><u>Solution:</u></h3>
Given that there are 18 pieces of chalk
To find: number of pieces of chalk that are yellow
Given that, ratio of chalk that is yellow to chalk that is not yellow is 1 : 2
Therefore,
chalk that is yellow : chalk that is not yellow = 1 : 2
Let the chalk that is yellow be 1x
Let the chalk that is not yellow be 2x
Also, total pieces of chalk = 18
That is,
chalk that is yellow + chalk that is not yellow = 18
1x + 2x = 18
3x = 18
x = 6
number of pieces of chalk that are yellow = 1x = 1(6) = 6
Thus 6 chalk pieces are yellow
