Johanna wrote the system of equations. 4 x - 3 y = 1, 5 x + 4 y = 9. If the second equation is multiplied by 4, what should the
polet [3.4K]

Answer:

The first equation must be multiplied by -5 to eliminate x variable by addition

Step-by-step explanation:

4 x - 3 y = 1 (1)

5 x + 4 y = 9 (2)

If the second equation is multiplied by 4

5x+4y=9. ×4

We have,

20x+16y=36 (3)

The first equation should be multiplied by -5 to eliminate x variable by addition

4x-3y=1 × -5

We have

-20x+15y=-5 (4)

Add equation (3) and (4) to eliminate x variable

20x+16y=36

-20x+15y=-5

31y=31

Divide both sides by 31

y=1

Substitute y=1 into equation (1)

4 x - 3 y = 1

4x-3(1)=1

4x-3=1

4x=1+3

4x=4

Divide both sides by 4

x=1

HELP ASAP ILL MARK U BRAINLIEST
prohojiy [21]

Answer: 300x200

Step-by-step explanation: First of all...Your perimeter equals 2x+3y. X=length, y=width.

2x+3y=1200

3y=1200-2x

y=400-(2/3)x

y=400-(2/3)x

Your Area = xy=x(400-2x/3)=400x-2^2/3

dA/dx=400-4x/3=0

4x/3=400

4x=1200

x=300ft length

y=400-(2/3)(300)=200ft

I hope this helps you!

All the fraction that are greater than 1\2
never [62]
Hi There!

Change all the fractions to decimal you do that by dividing numerator by the denominator. Remember \frac{1}{2}   as a decimal is 0.5

A=  \frac{3}{7}  =    0.43

B=  \frac{5}{9}  =    0.60

C=  \frac{8}{10} =   0.8

D=   \frac{5}{12} =   0.42

E=    \frac{3}{5}   =   0.6

Based, on the data above B,C,E are greater than \frac{1}{2} because they all have decimals greater than 0.5, B= 0.6, C= 0.8, E=0.6

So, \frac{5}{9} ,\frac{8}{10} ,\frac{3}{5}  are all greater than \frac{1}{2}

Hope This Helps :)
