There are 10 marbles in a bag 1/5 are red and the others are blue. What is the ratio of red to blue marbles?
Answers
Answer:
1:4 ratio
Step-by-step explanation:
The Answer is a 1:4 ratio because 1/5 of 10 is 2 and 4/5 of 10 is 8 so the ratio would look like 2:8. You would then simplify 2:8 to 1:4.
Ratio of red to blue marbles is 1:5
An equation is used to show the relationship between two or more numbers and variables.
10 marbles in a bag 1/5 are red and the others are blue.
number of red marbles = 1/5 * 10 = 2
number of blue marbles = 10 - 2 = 8
Ratio of red to blue marbles is 2:8 = 1:5

x=7
Step-by-step explanation:
first, add 12 to both sides so it would look like: 6x-12+12=30+12
so, ya get 6x=42
then you divide 6 from both sides, and that is: 6x/6=42/6
so x=7
6x= 30+12
2) add 30 and 12 to get 42
6x= 42
3) divide both sides by 6
x= 42/6
x=7

NO SILLY ANSWERS OR REPORT!
Answers
Answer:
13%
Step-by-step explanation:
The percentage decrease is calculated by the formula below;
( new value - old value)old value * 100%
old value is 130
new value is 115
So the percentage increase will be;

= 15/115 * 100% = 13.043%
To one decimal place, this is 13%

Given 28-6x=2x-84 prove x=14.
Answers
Answer:
-56
Step-by-step explanation:
substitute x with 14 in the equation and both answers will be -56
28-6x = 2x -84
Add 6x to both sides:
28 = 8x -84
Add 84 to both sides
112 = 8x
Divide both sides by 8
X = 112/8
X = 14

three more than a certain number is 6 less than 4 times that same number. what is the number?
Answers
Answer: 3
Step-by-step explanation:
Let x = the number
x + 3 = 4x - 6
-3x = -9
x = 3
The number that's represented by the information given will be 3.
Let the number be represented by x.
Since three more than a certain number is 6 less than 4 times that same number, then the number will be calculated thus:
x + 3 = (4 × x) - 6
x + 3 = 4x - 6
Collect like terms
4x - x = 3 + 6
3x = 9
x = 9/3
x = 3
Therefore, the value of the number will be 3.

Step-by-step explanation:
Step 1: Define
h(x) = 2x + 5
k(x) = x + 3
h(k(x))
Step 2: Substitute and Evaluate

Given that number of feet in one fence section be x
No of feet in 8 such fence section = 8x
Given , Perimeter = 8 fence sections = 8x feet
Cost of fencing of one foot = $6.50
Cost of fencing 8x feet = 8x * 6.50
Therefore , the total cost of the fencing can be given by = 8x*6.50

Lucy made a pumpkin pie to sell at a bake shop. She cut it into 6 slices and sold each slice for $1.25. How much money will she make if she sells the entire pie?
Answers
Answer:
$7.50
Step-by-step explanation:
Lucy cut it into 6 slices so the total is 6 and sold for $1.25 each slice so you multiply the total number of slices by the cost of each slice
6 times 1.25 = 7.5
7.5 = 7.50
So Lucy will make $7.50 if she sells the entire pie
Hope that helps dude !
