Answer:
4
Step-by-step explanation:
a triangle has angles that add up to 180°
an equilateral triangle has equal angles
so each angle is 60° (because 180/3 is 60)
so 10x +20 = 60
10x = 40
x = 4
The answer is 170. Hope this helps :)
10/3 bran flakes can make a dozen muffins
A recipe requires 2 1/2 cups of bran flakes
The recipe can make 9 muffins
Let's calculate the amount of bran flakes it will take to make 1 muffin
5/2 = 9
x= 1
cross multiply
9x= 5/2
x= 5/18
A dozen is 12, the number of bran flakes to make a dozen can be calculated as follows
5/18= 1
y= 12
cross multiply
y= 5/18 × 12
y= 10/3
Hence it will take 10/3 to make a dozen muffins

Answer: -79, 21, 46, 80
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
First multiply both sides by 2:
6x-10=4-x
Move the variable to the left-hand side and change its sign:
6x-10+x=4
Move the constant to the right-hand side and change its sign:
6x+x=4+10
Collect like terms:
7x=14
Divide both sides of the equation by 7:
x=2
