X + y = 40.....multiply by -4
4x + 6y = 180
-------------------
-4x - 4y = -160 (result of multiplying by -4)
4x + 6y = 180
------------------add
2y = 20
y = 20/2
y = 10 <===
x = 30
The answer is D. 15+18+12+5= 50 and there are 5 ramblers
<span>The correct answer is 50,000.
Explanation<span>:
We can set up the equation 5000=1/10x to represent this situation.
To solve, we will divide both sides by 1/10:
5000</span></span>÷<span><span>(1/10) = (1/10x)</span></span>÷<span><span>(1/10)
5000</span></span>÷<span><span>(1/10) = x.
To divide fractions, flip the second one and multiply; this gives us
5000*(10/1) = x
50000 = x.</span></span>
Answer:
C
You have to check which of numbers is the lowest.
Cheers :D
(I see that your concentrating on the task at hand with those YT and fortnite tabs open)
The area of the parallelogram is "base times height," so its 20*8 which is 160.
To find the area of the triangle, we have to find the base which incorporates Pythagorean'd theorem.
100 - 64 = 36, sqrt 36 is 6. So the base of the triangle is 6, the height is 12.6, thus the area is 6.3 * 6, which is 37.8
Adding the two values up, we get 37.8 + 160 = 197.8
