17x-3y=4 2x-4y=1 the solution to the system of equations is

Burka [1]

ANSWER

$x=\frac{13}{62}$

and

$y= \frac{-9}{62}$ e have

EXPLANATION

$17x-3y=4---(1)$

$2x-4y=1$

Let us make y the subject and call it equation (2)

$2x=1+4y$

$x=\frac{1}{2}+2y--(2)$

We put equation (2) in to equation (1)

$17(\frac{1}{2}+2y)-3y=4$

$\frac{17}{2}+34y-3y=4$

$34y-3y=4- \frac{17}{2}$

Simplify to get,

$31y= \frac{8-17}{2}$

$31y= \frac{-9}{2}$

Divide both sides by 31,

$y= \frac{-9}{2} \div 31$

$y= \frac{-9}{2} \times \frac{1}{31}$

$y= \frac{-9}{62}$

We put this value in to equation (2) to get,

$x=\frac{1}{2}+2\times -\frac{9}{62}$

$x=\frac{1}{2} -\frac{18}{62}$

We collect LCM to obtain,

$x=\frac{31-18}{62}$

$x=\frac{13}{62}$

The perimeter of a square is 52 meters. What is it area.

ValentinkaMS [17]

Answer:

169 meters

Step-by-step explanation:

52/4=13 (since it's a square you divide it by 4 because the sides are equal, so each side is 13 meters)

13^2=169 (to find the area you square the length of each side)

Solve the following inequality algebraically. ∣x−5∣≤11

Igoryamba

Answer:

$-6\leq x\leq 16$

Step-by-step explanation:

So we have the inequality:

$|x-5|\leq 11$

Definition of Absolute Value:

$x-5\leq 11\text{ or } x-5\geq -11$

Note that the sign is flipped in the second case because we multiplied by a negative.

Add 5 to both sides to both equations:

$x\leq 16\text{ or } x\geq -6$

Merge:

$-6\leq x\leq 16$

And we're done!

C = 0.20m + 2.00 what is the charge for 1mile ride?

RUDIKE [14]

All you have to do is substitute the 1 into the m for the mile ride:
C = 0.20(1) + 2.00 = 0.20 + 2.00 = 2.20

The charge for 1 mile ride is $2.20.
