Answer:
for question one - x = 12
Step-by-step explanation:
a triangle is always 180, in other words you will add all the corners equal to 180
ex (for first question) - 7x -2 + 4x + 5x - 10 = 180
you add like terms, the x with x and single numbers with numbers, which results in 16x - 12 = 180. then you do the original operation "what you do to one sign of the equal side you do to the other"
The answer is 8/5.
To divide fractions, flip the second fraction and multiply.
For example,
= 6/7 • 21/5
= 126/35
Simplify by dividing both sides by 7 to get your answer.
= 8/5
Answer:
x=1
Step-by-step explanation:
so just plug 1 in and you wil get it
2 1/2 yards of ribbon is 7 1/2 feet. (3 feet per yard)
She had 2 feet 8 inches left over after using a certain amount for the curtains.
So 2 feet 8 inches converted to fractions is 2 2/3 feet.
So our answer is the difference between 7 1/2 and 2 2/3 which is 4 5/6 feet.
Convert 4 5/6 feet to inches (12 inches in 1 feet) gives us a final answer of
58 inches.
Answer:
NO
Step-by-step explanation:
Recall: for a relation or a set of points to be a function, every x-value or input must have exactly one y-value or output.
From the given set of points, the x-value (inputs), -2, has two y-values (inputs), 1 and 3.
Therefore, the set of points does not represent a function.
