Step-by-step explanation:

First, convert the mixed fraction into an improper fraction:

$1\dfrac{2}{5} = \dfrac{7}{5}$

Rewrite 2 as 2/1 and then cross-multiply to combine:

$\dfrac{2}{1} - \dfrac{7}{5} = \dfrac{(2)(5) - (7)(1)}{(1)(5)} = \dfrac{10 - 7}{5} = \dfrac{3}{5}$

Answer:

y = 5

Step-by-step explanation:

y = mx + b

5 = 6m + b

5 = 3m + b

Take the first minus twice the second.

-5 = - b

b = 5

Substitute back to calculate m.

5 = 6m + 5

6m = 0

m = 0

How do I work this out???

Finger [1]

Okay so form a right angle triangle and the angle of that is 65 as it is right angle so 90 - 25= 65. label the sides like the pic below.

we have the hypothenuse as well as the angle and we are trying to find the o(opposite side)

o/h =sin
sin 65=23/h
sin 65 = 23/x
23/sin 65=x
x=25.4
how high the kite is above ground is :
= 25.4 +1.2
=26.6

A girls' choir is choosing a concert uniform. They can pick red, green, or purple sweaters, and they can pick tan or black skirt

<h3>Answer: C) 12</h3>

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

Explanation:

There are 3 colors of sweaters {red, green, purple} and 2 colors of skirts {tan, black}

So far there are 3*2 = 6 different outfit combinations. Imagine a table with 3 rows representing the sweater colors and 2 columns representing the skirt colors. There would be 6 cells in the table representing each possible combination. One cell would have (red sweater, tan skirt) for instance.

For each of those 6 combinations, we also have 2 shoe colors. So overall we have 6*2 = 12 outfit combinations

The tree diagram is shown below. Note how there are 3*2*2 = 12 different paths to follow.
