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
Answer:
x=3
Step-by-step explanation:
∠DBC+∠VBC is 180° since it is a straight line, ∠VBC=20x+5
The sum of all angles in a triangle is 180°, 9x-2 + 40° +∠DBC=180°
To find x, you can find ∠DBC first. *Don't forget BRACKETS
∠DBC=180-(20x+5)
∠DBC=180-(9x-2 + 40°)
Now equal the equations to each other to find x.
180-(20x+5)=180-(40+9x-2)
180-20x-5=180-40-9x+2
175-20x=142-9x
175-142=20x-9x
33=11x
x=33/11
∴x=3
You can find the slope using the following formula:
