Answer:
Option D.
LA Theorem or Postulates
Explanation:
LA theorem or postulates is leg-acute states that if the leg and an acute angle of one right triangle are congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.
In and
[Given]
[Acute angle] [Given]
[Given]
By LA theorems or postulates,
Therefore, LA theorems or postulates support the conclusion that the triangles are congruent.
Answer:
(3)
Replcaing equation (3) into equation (2) we got:
And solving for Y we got:
And solving for X from equation (3) we got:
So we need 3L of orange juice with 25% of concentration and 17 L of orange juice with 5% of concentration
Step-by-step explanation:
For this problem we can work with the concentration of water and orange juice.
Let X the amount for the orange juice with 25% content and Y the amount for the orange juice with 5% of content
Using the concentration of orange juice we have:
(1)
And for the water we have:
(2)
If we solve for X from equation (1) we got:
(3)
Replcaing equation (3) into equation (2) we got:
And solving for Y we got:
And solving for X from equation (3) we got:
So we need 3L of orange juice with 25% of concentration and 17 L of orange juice with 5% of concentration
Answer:
Step-by-step explanation:
Since y=x+1 plug it into bottom equation as y.
Subtract 1 from both sides
Subtract 5x from both sides
Divide both sides by -4
Now x=-3 into the top equation to find y
y=-2
