Answer:

Step-by-step explanation:

Note that the base angle of an isosceles triangle is equal hence;

3x+2 = 5x-30

3x - 5x = -30-2

-2x = -32

x = -32/-2

x = 16

Hence one of the base angle = 3(16)+2 = 50degrees

The sum of angle in the triangle is 180, hence

50+50+y = 180

100 + y = 180

y = 80 degrees

Hence the third angle is 80 degrees

Zoe has 1500 beads. She wants to make 6 friendship bracelets. She needs 215 beads for each bracelet. How many beads will Zoe hav
drek231 [11]
First you would need to find out how many beads are needed for the bracelets.

215 beads per bracelet x 6 bracelets = 1290 beads

This tells us that to make all 6 bracelets, it will use up 1290 beads, now subtract that from your total number of beads.

1500-1290= 210

So Zoe will have 210 beads left over. Since this is a word problem, it is best to answer it in the same format:

Zoe will use 1290 beads to make 6 friendship bracelets. After all of the bracelets are made, she will have 210 beads left over.

hope this helps!

forsale [732]
Let's break it down. 
You spent $20. Plus the $1 tip. 
20 - 1 = 19 
$19 is how much you spent without the tip
The cost for the taxi ride itself is $3
19 - 3 = 16
$16 is how much you spent without the ride cost + tip
You spent $2 for every mile traveled.
16/2=8 

You traveled 8 miles
