Answer: y = -3
Explanation:
-8 = 2y - 2
-2y = -2 + 8
y = 6/-2
y = -3
Answer:
It is a chemical change ⇒ 1st answer
Step-by-step explanation:
* Lets explain the statements to solve the problem
- <u><em>A chemical change</em></u> occurs when a new substance is formed through
a chemical reaction
- Ex: cooking an egg
- <u><em>Change of reaction</em></u> is the rate of reaction it can be decreases or
increasing
- <u><em>A phase change</em></u> is a change from one state to another without a
change in chemical composition
- Ex: Condensation: the substance changes from a gas to a liquid
- <u><em>A physical change</em></u>, such as a state change or dissolving, but does
not create a new substance
- Ex: Breaking a glass
* Lets solve the problem
- A piece of toast came out of the toaster very overcooked.
∵ It is like the cooking an egg
∴ It is a chemical change
Answer: Multiply both sides by 2.
Step-by-step explanation:
g divided by 2 is equal to 4 .
We could represent that with the equation :
To solve for g in this case multiply both sides by 2.
2 cancels out on the left side so we will be left with g. On the right side will be left with 8 after multiplying.
g = 8
<h3>answer.</h3>
•given that is smallest angle of rotational symmetry for a regular polygon is 30
•we have to find the number of side does the regular polygon have
•if we can rotate of figure around a center point be fewer than 360° and the figure appears and change then the figure has the rotation symmetry
<h3>Hence,12 number of sides the polygon.</h3>
no. of side= 360/ smallest angle at centre=12
