Answer: It's correct because it is the only one with an angle more than 180°
Step-by-step explanation:
D is a right angle, A is an acute angle, as well as B. So not only is C the only one with an obtuse angle and it also has the biggest angle out of the other two angles on the triangle, you can use process of elimination to figure it out as well. Hope this helps, have a good day! :-)
Answer:
90° is correct answer. :)
He needs 18.5 <span>meters of streamers
Just divide 1,850 by 100...
...and you'll get 18.5</span>
Answer:
x=2.833
Step-by-step explanation:
−4(3/2x−1/2)=−15
-4(3/2x)-4(-1/2)= -15
-2(3x)+2=-15
-6x=-15-2
-6x = -17
x= -17/-6
x=2.833
2(2x) + 1x = 40 or 4x + 1x = 40 is the result of combining by substitution
<em><u>Solution:</u></em>
Given that we have to combine 2y + 1x = 40 and y = 2x using substitution method
The substitution method for solving systems of equations involves expressing one variable in terms of another, thus removing one variable from an equation.
<em><u>Given equations are:</u></em>
2y + 1x = 40 -------- eqn 1
y = 2x ----------- eqn 2
We can substitute eqn 2 in eqn 1
Which means, substitute y = 2x in place of y in eqn 1
2(2x) + 1x = 40
4x + 1x = 40
5x = 40
x = 8
From eqn 2,
y = 2(8)
y = 16
Thus by combining using substitution method we found the solution
