Answer:
inequality equation: x<= -8
on the number line, there is a closed dot on -8, and is shaded left.
Step-by-step explanation:
so x/4 <= -2.
Multiply by 4
x<= -8.
Since it is a <=, the dot will be filled on negative 8, and shaded to the left, since it is a < sign.
Hope this helps!
5. 623. Just split the shape into two. then find the area of two figures that you created. Then add.
6. V = 138.125. Just multiply all the numbers together for this problem.
7. SA = 392. Use the formula <span>2(lw + lh + wh). </span>
Answer: 7/4 is greater
Step-by-step explanation: If you divide 7 by 4 you get 1.75. Then you divide 5 by 4 and you get 1.25. 1.75 is greater than 1.25. Also, if they have the same denominator, whichever has a higher numerator would be greater.
So, you go to the y axis and find 40 meters on the graph. Then, you go across to find out that x (time in seconds) is 20 seconds. So, in 20 seconds Tom walks 40 meters.
Let initially number of fishes =x
He gives 2/3 of his fish to a local high school, that is he gives 2x/3 fish .
So number of fishes left = x -(2x/3) = x/3 . And he gives 2/5 of x/3 to an elementary school , that is , he gives 2x/15 fishes to the elementary school. And finally the number of fishes left =30 , that is
So initially he have 150 fishes .
