I literally need this too and i have no idea
Remember you can do anything to an equiaotn aslong as you do it to both sides
try to isolae the variable then find 1 of it
50=7x-6
add 6 to both sides
56=7x
divide both sides by 7
x=8
3/4 of 3600..." of " means multiply
3/4 * 3600 =
10800/4 =
2700 <==
Answer:
208⅓ ft²
Step-by-step explanation:
The dimensions of Rachel's living room are 80 times the measurements on the scale drawing.
Calculate the width:
w = 80 × 1⅞
Convert the mixed number to an improper fraction = 80 × 15/8
Cancel the 8s = 10 × 15
= 150 in
Convert inches to feet = 150/12
Convert the improper fraction to a mixed number = (144 + 6)/12
= 12⁶/₁₂
Reduce the fraction to lowest terms = 12½ ft
Calculate the length
l = 80 × 2½ = 80 × 5/2 = 40 × 5 = 200 in = 200/12 = (192 + 8)/12
l = 16⁸/₁₂ = 16⅔ ft
Calculate the area
A = lw
A = 16⅔ × 12½
Convert the mixed numbers to improper fractions
A = 50/3× 25/2
Cancel the 2s
= 25/3 × 25
Multiply numerators and denominators
= 625/3
Convert the improper fraction to a mixed number
= (624 + 1)/3
= 208⅓ ft²
The area of Rachel's living room is 208⅓ ft².
Answer:
Step-by-step explanation:
Use the acronym SOH-CAH-TOA
sin = 
So opposite is 3 and hypotenuse is 4.
tan = 
So opposite is -3 and adjacent is 4.
cos = adjacent/hypotenuse
cos =
