Answer:
x = 8
y = 6
Step-by-step explanation:
First and foremost, it's an equilateral triangle, therefore all sides and angles are equal.
Knowing that the sum of angle in a triangle is 180°, therefore each angle is 60°.
Then equating (7x+4)° to 60, we have that,
7x+4=60
7x=60-4
7x=56
x=56÷7
x=8.
Answer:
y>−1
Step-by-step explanation:
y-6>-7
Add 6 to both sides
y-6+6 > -7+6
Simplify
y>-1
Answer:
12
Step-by-step explanation:
its just 12
Answer:
35.34305555555
Step-by-step explanation:
You must calculate the percentage taken out of the circle by the shaded region. This would be about 13.8%. Then you take the overall area of the circle and multiply it by the percentage. This should give you your answer.
REMEMBER TO ROUND IF YOU ARE SUPPOSED TO, THERE IS NO INDICATION ON BRAINLY. WITHOUT ROUNDING YOU CAN GET THE ANSWER WRONG.
Subtract 5y - 8 from 2y + 8
To subtract two numbers, we can do it like this:
10 - 4 = 10 + (-4)
That is, add the first number with the second number with its sign changed. For simple numbers, it does not make much difference, but for algebraic expressions, it can help a lot.
To subtract both binomials, we write the first plus the second with changed signs:
2y + 8
-5y + 8
---------------
-3y + 16
The result of the subtraction is -3y+16
