Answer:
The solution of the given system of equation is x = 50, y =18
Step-by-step explanation:
Here, the given system of equations are:
2x - 5y = 10 , x - 2y = 14
Now, from equation (2), we get x = 14 + 2y
SUBSTITUTE this value of y in the given equation (1)
We get: 2x - 5y = 10 ⇒ 2(14 + 2y) - 5y = 10
or, 28 + 4y - 5y = 10
⇒ 28 - y = 10
or y = 28 - 10 = 18
⇒ y = 18
Now, if y = 18, SUBSTITUTE this value of y in x = 14 + 2y
⇒ x = 14 + 2<u>y</u> = 14 + 2(<u>18</u>) = 14 + 36 = 50
Hence, the solution of the given system of equation is x = 50, y =18
Answer:
37
Step-by-step explanation:
50% of 74 is 74/2
<span>Leah, Let x=Blair's fish and 2x= Jay's fish; yet together they caught 27 fish. So, x + 2x=27; Combine the like terms. So, 3x=27; Now divide both sides of the equation by 3, therefore, x=9 which is the amt of fish Blair caught. So, 2(9)=18 is the amt of fish Jay caught. Check: 9 +2(9)=27; 27=27.</span>
1-2:<span>Yes. But not all parallelograms are squares</span><span>
3-false ! are </span><span>plane figures.
4-True ! </span>Every square is a rhombus<span>
5-False , </span><span>every rhombus is not a square.
6-7 : </span>Yes, all Squares are rectangles, but not all rectangles are squares because it needs to have all equal sides.
