Answer:

first number=15 second number=6

Step-by-step explanation:

lets take the first and second numbers as "a" and "b"

a-b=9

a+2b=27  (solve these equations simultaneously)

eliminating a

-3b= -18

b= 6

then substitute in the first equation

a-6=9

a=9+6

a=15

I really hope you know how to solve equations simultaneously

hope this helped

Write an equation in point-slope form for the line through the given point with the given slope. (-3,5); M=2/3
Setler79 [48]

Answer:

Step-by-step explanation:

y- y₁ = m(x-x₁)

y - 5 = 2/3 * ( x - [-3] )

y - 5= 2/3 * (x + 3)

y - 5 = 2/3x + (2/3) *3

y- 5 = 2/3x + 2

y = 2/3x + 2 +5

y = 2/3x + 7

A hiker standing at point G wants to estimate the distance across the lake to point H, which is directly north of her location.
riadik2000 [5.3K]

Answer:

D

Step-by-step explanation:

The diagram is attached.

Looking at the diagram, we want the side "opposite" of the angle given and the side "adjacent" is given.

Which ratio relates opposite and adjacent? It is Tan.

We can use trigonometry and tan ratio to solve for the distance "x":

Tan(84)=\frac{x}{650}\\x=Tan(84)*650\\x=6184.4

D is the correct answer.

What is an expression so that the product of a whole number and a decimal is 0.28
alisha [4.7K]

You may go the super easy way and choose 1 as the whole number and 0.28 as the decimal number. Then you'd obviously have 1\cdot 0.28=0.28

Otherwise, to be a bit more creative, you can observe that

0.28=\dfrac{28}{100} = \dfrac{14}{50} = \dfrac{7}{25} = 7\cdot \dfrac{1}{25}

And since 1/25=0.04, you can also choose 7 as the integer, and 0.04 as the decimal to get

7\cdot 0.04=0.28
