Answer:

x=7

y=2

Step-by-step explanation:

x-3y=1  ...(1)

3x-5y=11  ...(2)

subtract first from second eq.

3x-5y-(x-3y)=11-1

3x-5y-x+3y=10

2x-2y=10

x-y=5  ...(3)

(3)-(1) gives

2y=4

y=4/2=2

from (3)

x-2=5

x=5+2=7

You are trying to recreate flubber because you are obsessed with that movie and you thought it was the coolest. you take 70% sli
german

Let x be the amount (gal) of the 40% slime solution you end up using. You want to end up with 120 gal of the 50% solution, so that you would use 120-x gal of the 70% solution.

You want the final solution to consist of 50% slime, or 60 gal of slime. Each gal of the 40% solution contributes 0.4 gal of slime, while each gal of the 70% solution contributes 0.7 gal of slime. This means

0.4x+0.7(120-x)=0.5\cdot120=60

\implies0.4x+84-0.7x=60

\implies24=0.3x

\implies x=80

so the answer is B.

Find m&lt;DCV and m&lt;VBD​
max2010maxim [7]

9514 1404 393

Answer:

  • m∠DCV = 50°
  • m∠VBD = 50°

Step-by-step explanation:

Arc DV is 100°, so any inscribed angle that intercepts that arc will have a measure that is half of 100°, or 50°.

Inscribed angles DCV and VBD both intercept arc DV, so both are 50°.
