Answer:
a) 2.5
b)2.33
Step-by-step explanation:
a)
![4x-\frac{1}{2}= x+7](https://tex.z-dn.net/?f=4x-%5Cfrac%7B1%7D%7B2%7D%3D%20x%2B7)
Bring the numerals to the right hand side and the x terms to the left hand side
![4x-x=7+\frac{1}{2}](https://tex.z-dn.net/?f=4x-x%3D7%2B%5Cfrac%7B1%7D%7B2%7D)
Simplify
![3x=\frac{15}{2}](https://tex.z-dn.net/?f=3x%3D%5Cfrac%7B15%7D%7B2%7D)
Divide 3 on both sides, to get x
![x=\frac{5}{2} =2.5](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B5%7D%7B2%7D%20%3D2.5)
b)
![3x+2=2x+\frac{13}{3}](https://tex.z-dn.net/?f=3x%2B2%3D2x%2B%5Cfrac%7B13%7D%7B3%7D)
Bring the numerals to the right hand side and the x terms to the left hand side
![3x-2x=\frac{13}{3}-2](https://tex.z-dn.net/?f=3x-2x%3D%5Cfrac%7B13%7D%7B3%7D-2)
Simplify
![x=\frac{7}{3} =2.33](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B7%7D%7B3%7D%20%3D2.33)
Answer:
110degrees
Step-by-step explanation:
Complete question
Q4: If x and y are two supplementary angles whereas m<x=70 then find the m<y.
The sum of two supplementary angles is 180degrees, hence;
m<x + m<y = 180
70 + m<y = 180
m<y = 180 - 70
m<y = 110degrees
Hence the measure of ,=m<y is 110degrees
The answer is A.
The equation simplifies to y=3x+50.
So, C is already not an option.
Now we just plug in points to see if the point works for the equation.
A-11=3(-13)+50
11=-39+50
11=11
Thus, this point falls on the line of this equation and is a point.
So, the answer is A.
I hope this helps!
Answer:
1/7
Step-by-step explanation:
The triangle shown is a right triangle shown by the little square inside of it.
Area of a triangle is 1/2 x height x base
Rotating the shown triangle so the square is at a bottom corner the height is 6 and the base is 6
Area = 1/2 x 6 x 6 = 18 square cm
