Show the product -2• (-5) on the number line. Explain how you found your answer

Mathematics
1 answer:
inysia [295]3 years ago

Answer:

it would be difficult (or at least somewhat confusing) to try to diagram out this question with a drawing on a number line....

the concept here is that the -5, and -2 are NOT "subtracting" but "opposites"

so on a number line you can start at "-5" and draw an arrow to 5 and do the same for "-2"

then show the multiplication as a series of additions (5 2's added together)

Step-by-step explanation:

Point B is on line segment AC. If AB = x + 6, BC = x + 8 and AC = 10, then find the value of x.
kumpel [21]

Step-by-step explanation:

this simply means that the sum of both short segments must be the same as the length of the whole line.

so,

x + 6 + x + 8 = 10

2x + 14 = 10

x + 7 = 5

x = 5 - 7 = -2

<h3>You have the correct answer</h3><h3>Interest rate = 21.5%</h3>

===============================================

Work Shown:

i = P*r*t .... simple interest formula

i = simple interest

i = 2075-1000 = 1075

P = 1000 = amount borrowed (principal)

r = unknown interest rate

t = 5 = time in years

So,

i = P*r*t

1075 = 1000*r*5

1075 = 5000r

5000r = 1075

r = 1075/5000

r = 0.215

r = 21.5%
