The value of the variable x equation 0.2x+0.2+0.5x=-0.3x+1.2 is x=1.
Given a linear equation 0.2x+0.2+0.5x=-0.3x+1.2
Equation is a combination between two or more variables which is usually expressed in equal to form. Equation of two variable looks like ax +by=c. It is solved to find the quantity of x.
Given equation is as under:
0.2x+0.2+0.5x=-0.3x+1.2
It is a linear equation and will have only 1 solution. Linear equation is a equation which is having a straight line graph.
Adding the coefficients of variable
0.7x+0.2=-0.3x+1.2
Take -0.3 to other side
0.7x+0.3x=1.2-0.2
Adding the coefficients of variables
x=1
Hence the value of x in the equation 0.2x+0.2+0.5x=-0.3x+1.2 is x=1.

We find the common factor and reduce the fraction:
10/15 = (10/5) / (15/5) = 2/3
15/20 = (15/5) / (20/5) = 3/4
2/6 = (2/2) / (6/2) = 1/3
2/8 = 1/4
3/12 = 1/4
3/9 = 1/3
4/6 = 2/3
5/15 = 1/3
5/20 = 1/4
6/8 = 3/4
6/9 = 2/3
9/12 = 3/4
Answer:
There are many combinations based on the number you chose to subtract from both sides.
Step-by-step explanation:
Let the number be x.
According to the question,
3 x+7 > 4 x
We get, 3 x+1=4 x-6, after subtracting 6 from both sides.
3 x+1=4 x-6
4 x- 3 x=6+1
x=7
You will get the same answer if you subtract 3 x or 7 or any other number from both sides.
Thank you!
I will assume that is 19 2/5 INCHES.Set up a proportion with the actual height of the building.19.4 / h = 1/75Now, for cross-multiplying:H = 75 x 19.4 = 1455 feet.<span>That's a tall building!!!</span>
Answer:
The first offer: 100.80 for 4kg
Step-by-step explanation:
To find the best offer, we just need to find the price per kilogram, and we do this by dividing the price by the number of kg:
100.80 for 4kg: 100.8/4 = 25.2 per kg
170.50 for 5kg: 170.5/5 = 34.1 per kg
260.60 for 6kg: 260.6/6 = 43.43 per kg
320.40 for 7kg: 320.4/7 = 45.77 per kg
The first offer has the smaller price per kg, so it is the best offer.
