Answer: 10.5 (equivalent to the fraction 21/2)
To get this answer, you set 10x-15 equal to 90 and solve for x. The reason why these two angles are equal is because they are vertical angles.
10x-15 = 90
10x-15+15 = 90+15 ...... add 15 to both sides
10x = 105
10x/10 = 105/10 ...... divide both sides by 10
x = 105/10
x = 21/2 is the answer in fraction form
x = 10.5 is the answer in decimal form
You'll use what the vertical angles theorem tells you to solve this.
The vertical angles theorem says that vertical angles are congruent, which is what the angle with (10x-15) and the opposite angle (90) are.
Since they are vertical angles, they are congruent so you can set up an equation where they are equal and solve for x.
(10x-15) = 90
1. Get rid of the parentheses.
10x-15 = 90
2. Add 15 to both sides.
10x = 105
3. Divide both sides by 10.
x = 10.5
Answer is:
x = 10.5
Answer:
1/3
Step-by-step explanation:
There are 9 possible outcomes
We want the ones that have the same color which are GG , YY or BB
P ( same color) = number of same color outcomes / total outcomes
= 3/9
=1/3
Answer:
1/3
Step-by-step explanation:
3/9, simplify to 1/3
The value 78 is 12 times of number 6.
A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In orderto determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
12 times what equals 78
let the number whose 12 times equals 78 be x then
12 x = 78
Divide both side by 12
12x /12 = 78/ 12
x = 6

Probability(both marbles are red) = 5/12 * 4/11 = 20/132
= 5/33 Answer
Answer:
Hi so you need to find an intersection so like 2/2 and -1/-1 and you get one for both then you go up 3 from -1/-1 and go over 2 to get your 2/2 now you take 3 divided by 2=1.5
