I’m in a hurry, can someone answer these 2 questions? ?

For the beginning problem, let's refer to the given information so that we can write our addition expression. Win = 5, lose = -5, draw = 0, so we can substitute in these values into Blake's results.

lose, win, lose, win, win, lose, win, draw

-5 + 5 + (-5) + 5 + 5 + (-5) + 5 + 0

If we simplify by eliminating the parentheses and the zero, we get the following:

-5 + 5 - 5 + 5 + 5 - 5 + 5

Next, we can begin to compute this expression by eliminating pairs of -5 and 5 (which equal 0). Because there are three pairs of -5 and 5, we can eliminate these and make our expression a single number.

Therefore, Blake's point total for the first 8 rounds is 5.

For the next question, we must write a similar addition expression to represent the situation. Losing weight means that we should subtract that number and gaining weight means we should add that number to Aiden's starting weight. This is modeled below:

156 - 4 + 2 - 5 - 3 (this is the addition expression)

To find Aiden's new weight, we can just simplify this expression.

156 - 2 - 8

156 - 10

146

Therefore, Aiden's new weight is 146 pounds.

Hope this helps!

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
