First, you wrote -3x-7<20, that means -3x<20+7
or -3x<27 and we have x>-9
We draw the line of equation x= -9 and we have the set of solution is the haft of the plan on the right of the line x= -9
Step-by-step explanation:
g/6 - -53 = 57
g/6 + 53 = 57
g/6 = 4
g = 4×6 = 24
Answer: 72 units^2
Explanation:
Triangle to the left, you do 5(6) and get 30, but since it's a triangle, you divide by 2 and get 15. Middle rectangle, 6(8) is 48. Right triangle, 3(6) is 18, 18/2 is 9. Add them all up 15+48+9 and you get 72. Hope this helped!
Alright so what you want to do is add up the first and second day number of boxes, which would be 94, then you take 94 and subtract it by 150, (150-94). Once you do that you will have an answer of 56 so they would want to collect 56 more boxes on the third day. Hope this helps!!
Okay, so we know the first triangle is an equilateral and the second is an isosceles. (the lines indicate congruence)
To find x, we have to figure out the other triangle's angles.
Since it is equilateral, all its sides are 60 degrees.
All triangles angles add up to 180. 180/3= 60
To find x we subtract the angle beside it by 180 to find the angle's degree.
180-60= 120. x= 120.
Since it is an isosceles, the last two angles are the same.
Subtract the vertex from 180.
180- 120= 60
Divide that by 2. (since there are two angles)
y= 30 Or choice A. <span />
