Which steps can be used to transform the equation 2.3 + 2x = 4 + 4x into the equivalent equation 2.3 = 4 + 2x? A.
divide both sides by 22, then combine like terms
B.
add - 2x to both sides, then apply the associative property of addition
c. divide both sides by 2x, then cancel like terms
D
add-2x to both sides, then apply the distributive property of multiplication

answer: f = 32.2m

step-by-step explanation: that is the answer

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
