Mr. Hoya brought 5 watermelons from his grocery store. The watermelons weighed 8.25 pounds, 9.25 pounds, 8.875 pounds, 9.625 pou

Ronch [10]

The first thing we must do for this case is to find the total weight of the watermelons.
We have then:
$W = 8.25 + 9.25 + 8.875 + 9.625 + 10.75

 W = 46.75 pounds$
We now look for the amount of watermelons that people ate.
We have then:
$(0.25) * (153) = 38.25 pounds
$
Therefore, the amount of watermelon remaining is:
$46.75 - 38.25 = 8.5 pounds
$
We note that the amount of watermelon remaining is equal to 8.5 pounds.
Answer:
the amount of leftover watermelon is: equal to 8.5 pounds

Please please help me please!

Step-by-step explanation:

the number line : a potentially infinite horizontal line.

it shows all numbers, with 0 in the center, eher we are looking at it. the negative numbers go to the left of 0, with -1, -2, -3, ... going from right to left.

the positive numbers go to the right of 0, with 1, 2, 3 going from left to right.

point S = -14

and the distance to a point R (RS) is 10.

now, on such a line we can always go in 2 directions : left and right.

our starting point is S (-14).

going 10 units to the right (positive direction) we get to -4.

as -14 + 10 = -4

going 10 units to the left (negative direction) we get to -24.

as -14 - 10 = -24

so, R can be at -4 or -24.
