Using a number line how do i find 5+(-3)?

On the positive end of the line, locate point 5 and move 3 points toward zero (considering only whole number). So that, 5 + (-3) = +2

Step-by-step explanation:

Directed number can be easily located on the number line, which is a line with positive numbered end and negative numbered end separated by midpoint, zero.

So,

5 + (-3) = 5 -3 (since +1 × -1 = -1)

           = 2 (or +2)

This shows that the answer is two points away from zero on the number line (considering only whole number).

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
