1.2c=4.2 how do i solve?

c = 3.5

Step-by-step explanation:

1.2c=4.2

Divide each side by 1.2 to isolate the variable

1.2c/ 1.2=4.2/1.2

c = 3.5

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

see the picture for the graph.

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
