Answer:
157.5.
Step-by-step explanation:
(155 + 160) / 2
= 315/2
= 157.5.
Answer:
20 (im pretty sure)
Step-by-step explanation:
all angles should equal 360 so add them together and you get 340 so find what's missing—20
2+5-71
7-71
-64
answer is -64
Answer:
The graph of a linear equation is a straight line. The "solution" to a system of two linear equations is the point where the two lines cross. If the two lines are parallel, they never cross; hence parallel lines have no solution. Two lines are parallel if they have the same slope (the m value in y = mx+b). One of your equations is y = -2x + (you left the y-intercept out). The slope is -2. So any line with a slope of m = -2 will be parallel to this line and will not cross it. The second line also needs a different value of b, the y-intercept. Otherwise it is the same line and every point is a solution. So if your equation is:
y = -2x + 1
Then any equation of the form y = -2x + b, b≠1 will create a system with no solution. Hence the values of m and b are m = -2, b ≠ 1.
Given that :
- The tens digit of two digit number is twice the units digit.
- And there sum is 66.
To find :
Solution :
•Let us take the units digit be x
•Then the tens digit will be 2x [As it is given that the tens digit is two times the units digit]
A/Q
↪2x + x = 66
↪3x = 66
↪x = 66/3
↪x = 22
Therefore,the units digit is 22
And the tens digit is 2x = 2 × 22 = 44
