Find the value of x from the picture shown

Mathematics
1 answer:
Tamiku [17]3 years ago

Answer:

x=31°

Step-by-step explanation:

Ok,

We know the sum of the angles in a triangle add up to 180°.

So,

2x+63+(2x-7)=180

2x+63+2x-7=180

Add like terms

4x+56=180

4x=124

x=31°

Hope this helps!

You need 23 yards of fabric to make five dresses. How many yards of fabric would be needed to make 8 dresses?
olasank [31]

Answer:

36.8 or 37 yards of fabric

Step-by-step explanation:

23 yards of fabric = five dresses

23 divided by five equals four point six

four point six multiplied by eight dress equals 36.8

23 yds of fabric = 5 dresses

23÷5=4.6

If you need to know how many yards of fabric, then you'd do:

4.6×8

4.6 is the amount of each yards 5 dresses are in and so if you times that by how many dresses you need now, you'll get:

36.8 yards of fabric

To round, it'd be 37 yards of fabric
