Answer:

(D). The number that is 7 to the right of 2 on the number line​

Step-by-step explanation:

It could also be the number that is 2 to the right of 7 on the number line. When numbers are added, the distances of each to the origin are laid end-to-end from the origin to the right on the number line.

2+7 can mean that the distance 2 is added to the distance 7, or vice versa. (The commutative property of addition says order does not matter.)

Two birds sit at the top of two different trees. The distance between the first bird and a birdwatcher on the ground is 32 feet.
mestny [16]

Answer:

x = 45.3°

Step-by-step explanation:

The distant between the first bird and the bird watcher is opposite to the reference angle, x° = 32 ft

The hypotenuse is the distance between the second bird and the bird watcher = 45 ft.

Therefore,

sin(x) = \frac{opp}{hyp} = \frac{32}{45}

sin(x) = \frac{32}{45} =  0.7111

x = sin^{-1}(0.7111)

x = 45.3

Arianna has $0.70 worth of nickels and dimes. She has 4 more dimes than nickels. By
jekas [21]

Answer:

x=2 and y=6

Step-by-step explanation:

thee isn't any other way im sorry but there isn't here is a list:

1 nickel = $0.05 and 5 dimes =$0.50 = $0.55

2 nickels = $0.10 and 6 dimes = $0.60 = $0.70

3 nickels = $0.15 and 7 dimes = $0.75 = $0.85

4 nickels = $0.20 and 8 dimes = $0.80 = $1.00

5 nickels equal $0.25 and 9 dimes equals $0.90 = $1.15

so as you can see the more you add the higher the number gets and if its any lower it won't be enough sorry if you really needed that last part

3 miles. Using cross-multiplication, 3×4 = 12 and 4×1 = 4, so 12/4 = 3.
