Answer:
The correct answer is first option
(2, 3)
Step-by-step explanation:
It is given that,
3y = -x + 11 and
x + 4y = 14
<u>To find the solutions</u>
The given equation can be written as,
x + 3y = 11 --------(1)
x + 4y = 14 -------(2)
Subtract (1) from (2) we get
y = 3
Substitute vale of y in eq(1)
x + 3*3 = 11
x = 11 - 9 = 2
Therefore x = 2 and y = 3
The correct answer is first option
Answer: -18, -20, -22
Step-by-step explanation:
The integers are obviously approximately equal to -20, since they cover only 5 numbers, and there are three of them and their sum is -60. So guess -18, -20, -22. That works.
From the markings and lines, we can tell this is an equilateral triangle. Since it is an equilateral triangle, we know that each angle is 60°.
Using this information, we can make and solve an equation:
8y - 4 = 60° <em>(we know that it is equal to 60°, since it is an equilateral triangle)</em>8y = 64° <em>(we added both sides by 4 to get the y's alone on one side)</em>y = 8° <em>(we divide both sides by 8 to find out what just y is)</em>-------------------------------------------------------------------------------------------------------------Answer:
So y is equal to 8°
Answer:
3^2 = 9
9 x 3.14 = 28.26
28.26 divided by 4 = 7.065 (round) = 7.07
