The angles x+35 and x+ 40 should equal to the angle supplementary to angle A. You get the equation 2x+75=x+110. You will want to get x alone on one side. First you have to subtract 75 to the right to get 2x=x+35 and then subtract x to the left. You get x=35. Hope this helped!

Ming wants to make a 40% sugar solution. She had already poured 3 L of a 80% sugar solution into a beaker. How many L of a 10% s

jeyben [28]

Answer:

Ming must add 0.375 L of a 10% sugar solution

Step-by-step explanation:

if 3 L = 80%

1.5 L should = 40% (since it is half of 80%)

and if 40 divided by 4 = 10%

1.5 also needs to be divided by 4

so 1.5 divided by 4 = 0.375

that means Ming must add 0.375 L of a 10% sugar solution

PLEASE HELP ME . how can the converse of the Pythagorean theorem help you determine whether the roped off area is in the shape o

trapecia [35]

Step-by-step explanation:

From the Pythagorean theorem we have:

$a^2+b^2=c^2$ <em>subtract b² from both sides</em>

$a^2=c^2-b^2\to a=\sqrt{c^2-b^2}$

Same:

$b=\sqrt{c^2-a^2}$
