Solve the system: y = 3x -x + 2y=5 (_,_)

Mathematics
1 answer:
kakasveta [241]3 years ago

Answer:

(5, 15)

Step-by-step explanation:

-x + 6x = 5

5x = 5

x = 5

y = 3 (5)

y = 15

You can substitute 6x for 2y because it says y = 3x. So 2y is gonna be 6x because you have to multiply it by 2 since it's 2y not just y.

Given that m∠ABD = 84° and m∠BAC = 37°, what is the m∠ACD?
stich3 [128]

Answer: 84°

Step-by-step explanation:

Pardon my drawing, I know it;s not prefect, and I'm not sure how to draw a figure on Brainly, but this is the best I can do. For this problem, it is easier to draw it out so you can see that the angles look like. Just pretend the lines are filled in, and this is a perfect parallelogram.

       

      A   ________________ C

        /                                   /

      /                                  /

    /                                 /

B /_______________/ D

As you can see, the angles given in the problem gives us a parallelogram. Since we know m∠ABD is 84° and m∠BAC is 37°, we know that m∠ACD is 84°. If you draw diagonal lines, ∠ABD and ∠ACD are vertical angles. Vertical angles are congruent. Therefore, m∠ACD is 84°.

HI OMG ILL GIVE BRAINLIESST PLEASE HLEP ME
Vesnalui [34]

Answer:

233.19 inch³

Step-by-step explanation:

Volume of prisms: Length * Width * Height

given for first prism: Length = 7 cm  Width = 3.25 cm Height = 7 cm

given for second prism: length = 7 cm width = 3.25 height = 3.25

using the formula:

Total volume: prism 1 volume + prism 2 volume

Total volume: 7 * 3.25 * 7 + 7 * 3.25 * 3.25

                     : 159.25+ 79.9375

                     : 233.1875 inch³

                     : 233.19 inch³ .........rounded to nearest hundredth

LekaFEV [45]

Answer:25,000(0.15)^x

Step-by-step explanation:

I think this is the answer because there are 25,000 gray wolf in the world and they are expected to grow by 15%. 15% is .15. So those two numbers multiplied, to the x exponent should give you the answer of how large the wolf population is expected to be.
