A drawer has some red, green, and blue marbles. There are 33 marbles.There are 4 times as many red marbles as green marbles. There are half
as many blue marbles as green marbles. How many blue marbles are in
the drawer?

Answers

Green marbles = x.
There are 4 times as many red marbles as green marbles, so red marbles = 4x.
There are half as many blue marbles as green marbles, so blue marbles = 0.5x
There are 33 marbles in total, so x+4x+0.5x=33.

$x+4x+0.5x=33 \n 5.5x=33 \n x=(33)/(5.5)=(330)/(55)=(30 * 11)/(5 * 11)=(30)/(5)=6 \n \n0.5x=0.5 * 6=3$

There are 3 blue marbles.

so number of red is represented by r
number of green is represented by g
number of blue is represented by b

so r+g+b=33

there are 4 times as many red as green or
r=4g
there are half as many blue as green
1/2g=b or g=2b

so r+g+b=33
we can subsitute 1/2g=b for b
r+g+1/2g=33
subsitute r=4g for r in the equation
4g+g+1/2g=33
add like terms
5 1/2g=33
multiply both sides by 2
11g=66
divide both sides by 11
g=6

there are 6 green marbles

subsitute g=6 into r=4g and g=2b

r=4(6)
r=24
there are 24 red marbles

g=2b
6=2b
divide both sides by 2
3=b
threre are 3 blue marbles

there are 24 red marbles, 6 green marbles, and 3 blue marbles and 24+6+3=33
r=24
g=6
b=3

What is the value of x?
23
35

93

Answers

Question: What is the value of x?

Answer: The answer would have to be x=93°.

Explanation: The answer would have to be x=93°, because x is obtuse and 93 is the only measure that measures an obtuse angle.

x is 35, if you follow the rules of alternate angles

Rearrange the equation A = xy to solve for x.x = y over A
x = A times y over x
x = A times x over y
x = A over y

Answers

Answer:

x = A over y

Step-by-step explanation:

we have

$A=xy$

Solve for x

That means -----> isolate the variable x

Divide by y both sides

$A/y=xy/y$

Simplify

$A/y=x$

Rewrite

$x=A/y$

therefore

x = A over y

Answer:

The correct option is D) x = A Over y.

Step-by-step explanation:

Consider the provided equation.

$A = xy$

We need to solve the equation for x.

Divide both the sides by y.

$(A)/(y) = (xy)/(y)$

$(A)/(y) = x$

$x=(A)/(y)$

Hence, the value of the provide equation for x is $x=(A)/(y)$ .

Thus, the correct option is D) x = A Over y.

How many triangles can you construct with the angle measures of 50, 70, and 100?

Answers

Answer:

Step-by-step explanation:

You can't construct any triangles with those angles. Because when you add all the angles of a triangle, it has to add up to 180. But when we add 50,70, and 100, it equals 220. So you can't construct any triangles.

Hope this helps. (If it does, please mark me brainliest)
