Your first equation is 4x + 7y= 32, the x’s representing the brushes and the y’s the tubes of paint. Our second equation is 6x+8y=43. What I did is I multiplied the first equation by 1.5 so that it turns into 6x+10.5y=48. Then I subtracted the second equation from the first, canceling out the x’s and leaving us with 2.5y=5. Then divided and got y=2. We then go back to any of the original equations and plug it in to get the x’s.
6x+8(2)=43. We get 6x+16=43. We subtract and are left with 6x=27 and then x=4.5. Then plug both of them in to a different equation to double check. You could also use substitution by isolating one of the variables in one equation and then plugging it in to the other one.
Answer:
Step-by-step explanation:
m<ARL and m<LRB together equal 180 degress.
x=37.4
So 2(37.4)-5 is
m<LRB=69.8
Answer:
f,j
Step-by-step explanation:
Answer:
Examples of undefined terms are point, line, and plane.
Step-by-step explanation:
This relates to parallels lines as, by definition, they require the undefined terms line and plane. I hope this helps!
The sum of the two short legs must be at least as long as the longest leg.
This requirement for a triangle is NOT met by the 2nd selection. Those lengths cannot be a triangle.
