Find the value of X. Then find the measure of each labeled angle.

wariber [46]

Both angles WILL have the same measure.

So,

3x-10= x+40 (you have to set the equations equal to one another)

Now, add 10 to both sides.

3x=x+50

Subtract x on both sides.

2x=50

Divide both sides by 2.

x=25

Now, plug in x.

(25 +40)= 65

(3(25)-10)= 65

x equals 25 and both angles are equal to 65. Or "B".

I hope this helps!

Two identical jars are filled with equal numbers of marbles. The marbles are colored red or white. The ratio of red to white mar

IrinaK [193]

Let $a=$ the number of white marbles in Jar 1
Let $b=$ the number of white marbles in Jar 2
Total number of white marbles is $a+b=90$

Jar 1 has $a$ white marbles and $7a$ red marbles so $8a$ marbles total
Jar 2 has $b$ white marbles and $9b$ red marbles so $10b$ marbles total
Since both jars have equal amounts of marbles, $8a=10b$

We have a system of equations:
$a+b=90$
$8a=10b$

The number of red marbles in Jar 2 is $9b$ so we solve for $b$

$8a=10b$
⇒ $a=\frac{5}{4}b$
⇒ $\frac{5}{4}b+b=90$
⇒ $\frac{9}{4}b=90$
⇒ $b=40$
Number of red marbles in Jar 2 is $9b=360$

So there are 360 red marbles in Jar 2.
