Explain how you would solve 25- 6R when R = 3. Make sure to explain each step.

aliina [53]

Fist you need to substitute the value of R into the equation

25-6(3)

Now you simply
First multiple 6(3)

25-6(3)
25-18

Now solve!
25-18
7

The answer is 7

Answer:

x = 88.463°

Step-by-step explanation:

We are given a trigonometric equation and we need to find out the value of x. The angle x lies between 0° and 360° . That is ,

$\rm\implies\red{ 0^0 < x < 360^0 }$

Given trigonometric equation :-

$\rm\implies\red{ 1 + 5 sin (x-100^0)=0 }$

Subtracting 1 both sides , we have ,

$\rm\implies 5sin( x - 100^0)= -1$

Divide both sides by 5 ,

$\rm\implies sin( x - 100^0)= \dfrac{-1}{5}$

This equation can be written as ,

$\rm\implies x - 100^0 =sin^{-1}\bigg(\dfrac{ -1}{5}\bigg) \\\\\rm\implies x - 100^0 = -11.53^0 \\\\\rm\implies x = 100^0-11.53^0\\\\\rm\implies\boxed{\bf x = 88.463^0}$

Zachary is 1 year older than his sister, Nicole. Jaycob is

shtirl [24]

Answer:

Zachary is 9, Nicole is 8, and Jaycob is 27.

Step-by-step explanation:

x=Zachary

y=Nicole

z=Jaycob

x+y+z=44

x*3=z

x-1=y

However, for now, let's just assume that x and y are actually the same, and that the answer is actually 45.

so, x*3=z, and y*3 also equals z.

This is so that technically, 45/5=x, because z accounts for 3, and both x and y account for 1 each, meaning altogether it should be 5 you should be dividing by. 45/5=9, so x=9. Now that we have that figured out, we can solve the rest easily. 9-1=8, so there's your y, and 9*3=27. 27+9=36, and 36+8=44.
