Solve the literal equation for y. 4x-5=7+4y
Natalka [10]

Answer:

y=x−3

Step-by-step explanation:

Flip the equation.

4y+7=4x−5

Add -7 to both sides.

4y+7+−7=4x−5+−7

4y=4x−12

Divide both sides by 4.

\frac{4y}{4}= \frac{4x-12}{4}

y=x−3

ik this doesnt make any sense but hope this helps :/

A dinner plate has a circumference of 106.76 cm. What is the area of the dinner plate? Use = 3.14.
Sphinxa [80]
C=2pr,  r=c/(2p)

a=pr^2, using r found above we get:

a=p(c^2/(4p^2))

a=(c^2)/(4p), since c=106.76 and we approximate pi as 3.14

a=(106.76^2)/(4*3.14)

a=11612.2176/12.56 cm^2

a≈924.54 cm^2  (to nearest one-hundredth of a square cm)
