PLZ HELP AND SHOW YOUR WORK <3333 Substitution. 3x+2y=11 y=5x-1

liraira [26]

Hey there! :D

Substitute y for 5x-1.

3x+2y=11

y=5x-1

3x+2(5x-1)=11

3x+10x-2=11

13x-2=11

13x=13

x=1

Now, plug that in to find y.

y=5x-1

y=5(1)-1

y=5-1

y=4

(1,4) <== the solution

I hope this helps!

NNADVOKAT [17]

Statement 1 : Gail bought a $45 sweater at 1/3 off.

Discount in Sweater Purchase:

$\frac{1}{3} \; of \; 45 = \frac{1}{3} \times 45 \; = \;\frac{45}{3} =\$15$

Statement 2: Gail can use her 12% employee discount once a week and used her discount on the suit priced at $140.

Discount in Suit Purchase:

$12\% \; of \; 140 =\frac{12}{100} \times 140 = 0.12 \times 140 = \$16.8$

Conclusion:

Discount in Suit Purchase ($16.8) is greater than Discount in Sweater Purchase ($15)
