Marta drew a scale drawing of her backyard. she used the scale 1/2 inch =4.5 feetif the actual length of her backyard is 54,what is her scale drawing in inches

1/2 inch…………4.5 feet

x inches……….54 feet

x=(54•1/2)/4.5

x=27/4.5

x=6 inches

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
