Answer:
The third side of the triangle is 10x + 3
Step-by-step explanation:
x + 1 + 2x + 4 = 3x + 5
( 13x + 8 ) - ( 3x + 5 ) = 13x + 8 - 3x - 5
= 10x + 3
Answer:
Step-by-step explanation:
18y -30 -7y =25
solution
18y -30 -7y =25
so we take like terms that is unknown to unknown whole number to whole number or you can put it this way to remember(brothers go to brothers are the ones with an alphabet , sisters go to sisters they are the ones without an alphabet numbers)......okay lets continue
18y -7y=25+30
when a negative is crossing an equal sign it turns positive and vice versa
so lets solve
11y=55
the one with the unknown will divide
11y/11=y
you cant say 1y its wrong in maths you can say in another subject but not maths....okay...so we say y the 1 is invisible but you can say 2y ,3y etc
Then 55/11=5
so y=5
Thats the correct answer....
Answer:
A
Step-by-step explanation:
Answer:
$12,800
Step-by-step explanation:
42-18= 24
24 is the years the money is growing.
24/4=6
200x2x2x2x2x2x2=12,800
if it doubles every six years it would be 200x2x2x2x2=3,200
the difference is 9,600
Answer:
x=2 and y=-6 aka. (2,-6) which is the point of intersection
Step-by-step explanation:
Use elimination to cancel out y by adding the equations:
5x=10
x=2
Plug x=2 into one of the equations and find y:
2(5)+2y=-2
10+2y=-2
2y=-12
y=-6
Therefore, x=2 and y=-6
