Write an equation and solve it. The difference between a number and three-fourths is one-half.

Which equation and solution is correct?
Three-fourths minus one-half = x; x = one-fourth

x minus one-half = three-fourths; x = 1 and one-fourth

Three-fourths minus x = one-half; x = one-fourth

x minus three-fourths = one-half; x = 1 and one-fourth

x-3/4=1/2; x=1 and 1/4

Step-by-step explanation:

Got it right on edg 2020 :D

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
