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

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

What is an expression in one variable?An expression in one variable is a statement formed by the using constants and an unknown variables and mathematical operators but sign is equal to is not used. Expression in one variable is linear if the power of the unknown variable is equal to one .
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

Answer:
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

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

What was the percentage increase to one decimal place?
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;
(130-115)/115 * 100%
= 15/115 * 100% = 13.043%
To one decimal place, this is 13%
