A-5/a divided by 4/a

Mathematics
1 answer:
maria [59]3 years ago
6 0

Answer:

\frac{a-5}{4}

Step-by-step explanation:

the given equation is

\frac{a-5}{a} /\frac{4}{a}

from the multiplication rules we know that

\frac{a}{b}/\frac{c}{d}=\frac{a}{b}*\frac{d}{c}

so for the given equation changing the sidn of division to multiplication

the equation becomes

\frac{a-5}{a} * \frac{a}{4}

a cancels out from both numerator and denominator

so it becomes

\frac{a-5}{4}

which is the answer

Consider the following pair of equations:
Zinaida [17]

Answer:

The lines representing these equations intercept at the point (-4,2) on the plane.

Step-by-step explanation:

When we want to find were both lines intercept, we are trying to find a pair of values (x,y) that belongs to both equations, which means that it satisfies both equations at the same time.

Therefore, we can use the second equation that gives us the value of y in terms of x, to substitute for y in the first equation. Then we end up with an equation with a unique unknown, for which we can solve:

x+y=-2\\x+(2x+10)=-2\\x+2x+10=-2\\3x+10=-2\\3x=-2-10\\3x=-12\\x=\frac{-12}{3} \\x=-4

Next we use this value we obtained for x (-4) in the same equation we use for substitution in order to find which y value corresponds to this:

y=2x+10\\y=2(-4)+10\\y=-8+10\\y=2

Then we have the pair (x,y) that satisfies both equations (-4,2), which is therefore the point on the plane where both lines intercept.
