Answer:
310
Step-by-step explanation:
A circle is 360 degrees
50 +x = 360
x = 360-50
x = 310
Answer: y=-6x-57
Step-by-step explanation: the normal format of a linear equation is
y=(slope)x+y intercept. The slope is -6 so y=-6x+y intercept. Plugging in the cordinates, -3=-9(-6)+y intercept. We'll call the y intercept b. -3=54+b. Subtract 54 from both sides of the equation and you get b=-54. The linear equation is
y=-6x-57.
You can check by plugging in x= -9, and y= -3. -3=54-57. -3=-3
Answer:
x = 39.1
Step-by-step explanation:
mean = average off all the numbers =
sum of the numbers / amount of numbers.
35 = sum of the #'s / # of #'s
35 = 100.9 + x / 4
35 × 4 = 100.9 + x / 4 × 4
140 = 100.9 + x
140 – 100.9 = 100.9 + x – 100.9
39.1 = x
x = 39.1
Answer:
Step-by-step explanation:
x > 3 reads x is greater than three. This includes all numbers to the right of three, but not three itself. |₋₋|₋₋|₋₋₀---|---|---|---|---|---|----->
