You'd have no problem simplifying that expression if it said
-(5 cows) - (1 cow) + ( 14 cows) - (3 cows) .
You'd just add up the cows, and simplify the expression to say
5 cows .
When you see an expression that talks about 'x's instead of cows,
you get scared. It has something to do with algebra and math and
all that stuff, so you freeze.
Relax. Just make each 'x' a cow, and suddenly it almost solves itself.
Answer:
x= -2/5 and x= 3
Step-by-step explanation:
Given equation is,
5x^2 - 13x - 6 = 0
Or, 5x^2 - 15x + 2x - 6 = 0 ( using middle term method)
Or, 5x( x- 3) + 2 (x-3) = 0
Or, (x-3) (5x+2) = 0
Now, x will have 2 answers because it's degree is 2. Total number of values depends on the power of variable.
So, x= 3 or, 5x = -2
Or, x= -2/5
So, the answer is x= -2/5 and x= 3.
To compare these two values, we need them to be in the same form.
To convert 20% into a decimal, we divide 20/100, or 0.20.
When comparing decimals, we know that 0.2 > 0.02.
Therefore, 20% > 0.02. (20% is greater than 0.02)
Answer:
y-7 = 4(x+9)
Step-by-step explanation:
Point slope form is
y-y1 = m(x-x1)
where m is the slope and (x1,y1) is the point
y-7 = 4(x--9)
y-7 = 4(x+9)
She worked 2 and 1/2 hours yesterday, and today she did 4 and 1/4 hours.
first off, let's check how many hours she worked total, and divide 54 by it.
so, first off, let's convert the mixed fractions to "improper" and add them up.
