Find the missing angle or find X?

Sindrei [870]

X = 60°
Because the square in the corner tells you that it is 90° (right angle)
So your equation to solve for x would be...
x + 30 = 90
Now you need to isolate the x.

Subtract both sides by 30.
x + 0 = 90 - 30
x = 60

Write Y+2=1/3x in standard form

solong [7]

The standard form of a line is in the form

$Ax + By = C$

A, B and C are integers, and A is positive. Let's start with multiplying the whole equation by 3 to get rid of denominators:

$3y+6=x$

Subtract 3y from both sides:

$6=x-3y$

Which of course is equivalent to

$x-3y=6$

Which is the standard form, given the coefficients A=1, B=-3, C=6.

Nour and Rana are shopping for a Christmas tree. They are deciding between 222 different types of trees (real and fake) and 444

ioda

From what the statement says the question seems to be to represent the sample space of randomly choosing a type of tree and a color for the decorations

In this case, what we must do is identify the events that exist and the options that each event has, like this:

Event 1:

Tree type: real or fake

Event 2:

Colors for the ornaments: White (W), Silver (S), Gold (G) or Purple (P)

Since in an event there are 2 options and the other 4 options, the final number of options would be 2 * 4, that is, 8 options, represented below:

(real, W), (real, S), (real, G), (real, P), (fake, W), (fake, S), (fake, G), (fake, P)

The above would be the sample space of the events.

Now the probability of 1 coming out is 1 over the event total, or 1/8.
