1.2x+3.7=2.2x - 4.5 what does x=

Mathematics

valentina_108 [34]3 years ago
6 0
Simplifying
1.2x + 3.7 = 2.2x + -4.5

Reorder the terms:
3.7 + 1.2x = 2.2x + -4.5

Reorder the terms:
3.7 + 1.2x = -4.5 + 2.2x

Solving
3.7 + 1.2x = -4.5 + 2.2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2.2x' to each side of the equation.
3.7 + 1.2x + -2.2x = -4.5 + 2.2x + -2.2x

Combine like terms: 1.2x + -2.2x = -1x
3.7 + -1x = -4.5 + 2.2x + -2.2x

Combine like terms: 2.2x + -2.2x = 0.0
3.7 + -1x = -4.5 + 0.0
3.7 + -1x = -4.5

Add '-3.7' to each side of the equation.
3.7 + -3.7 + -1x = -4.5 + -3.7

Combine like terms: 3.7 + -3.7 = 0.0
0.0 + -1x = -4.5 + -3.7
-1x = -4.5 + -3.7

Combine like terms: -4.5 + -3.7 = -8.2
-1x = -8.2

Divide each side by '-1'.
x = 8.2

Simplifying
x = 8.2

Write a expression that can be used to multiply 6x198
nydimaria [60]

In this problem, we are asked to give an expression that can be used to mentally multiply 6 and 198. In order not to go through the rigorous multiplication, we can estimate 198 to 200, that is 6 *200 equal to 1200. Since there is a 2*6 excess or 12 then we subtract: 1200 -12 equal to 1188.

A child gets 20 heads out of 30 tosses of a coin. If he declared the chance of getting a head with that coin were 2/3, that woul
Komok [63]

Answer: Experimental probability

Step-by-step explanation:

There are two kinds of probability: Theoretical probability and Experimental probability.

To calculate theoretical probability we divide favorable outcomes by total outcomes.

To calculate experimental probability we divide number of times an event occurs by the total number of trials or times the activity is performed.

Here, A child gets 20 heads out of 30 tosses of a coin. If he declared the chance of getting a head with that coin were 2/3, which is dependent on the activity he performed, thus it is an experimental probability.
