Let's first find how many students bring their lunch to school. This is 30% of 300. To find this value, convert the percentage to a fraction (or decimal) and multiply:

Since 90 students bring their lunch to school, we can say 210 students do not bring their lunch to school. (300 - 90 = 210)
Answer: x=13
explanation:
-2x+6=-20
subtract 6 from both sides
-2x=-26
divide -2 by both sides
two negatives equals a positive
x=13
Answer:
3
Step-by-step explanation:
x − (y − y)
3-(6-6)
3-0

Answer:
a = 6
Step-by-step explanation:
Given information:
Slope = 6
Coordinates: (-9, 0) and (-8, a)
Slope formula = y2 - y1 / x2 - x1
Substitute the given values into the formula.
6 = a - 0 / -8 - (-9)
6 = a - 0 / 1
6 = a - 0
a = 6
hope this helps!! p.s. i really need brainliest :)
Answer:
NO triangle exists.
Step-by-step explanation:
Given that the sides of the triangle are a=43 ,b=82 , and c=28
To solve for unknown angles of the triangle
PLease refresh the triangle rule of inequality that the sum of any two sides is always greater than the third side
Before solving the triangle, let us check whether this is true.
a+b >c
b+c>a
But a+c is not greater than b.
Hence there cannot be any real triangle with these sides given.
Answer is no triangle exists.
