Put a parenthesis before the 2 and after the 4.4
(2 x 4.7 - 4.4) = 9.4 - 4.4 = 5
45 divided by 5 times 6 equals 54
If the equation is (5x + 3 - 7) / 2 = 56, than x = 23.2
Since this is a linear equation with 2 variables, it is an unsolvable equation as a and b could be anything, to find an exact answer you need another equation that relates to the first one.
The domain of the function f(x) = (x + 2)^-1 is whatever you choose it to be, except that the point x = -2 must be excluded. If the domain comes up to, or straddles the point x = -2 then that is the equation of the vertical asymptote. However, if you choose to define the domain as x > 0 (in R), then there is no vertical asymptote.
You would need one more equation relation x and y to solve for both of them.
v/7x = w/y Multiply both sides of the equation by x, to get: v/7 = xw/y Multiply both sides of this equation by y/w, to get: vy/7w = x .
Be more specific and add parentheses
Parentheses, also known as brackets, show that whatever lies within them must be solved before anything else, and must be treated as a single chunk of an equation. For example: 2*(4+3) tells you to solve the '4+3' part of this problem first, which gives 2*7. If the brackets weren't there, the equation would be 2*4+3, which equals 8+3, or 11.
18=3(3x-6)
With no parentheses, that equals 30.
The parentheses would be placed thus: 27 - (49 / 7 + 12) = 8
A equals Vf minus Vi divided by time equals triangle v divided by time
9
Since there are no parentheses (brackets) the expression is evaluated from left to right and so 696 / 3 * 2 = 232 * 2 = 464
0.5
36 divided by 9 equals 4
63
25 ÷ (5-4) = 25
