Andre’s equation is y = 5x + 100 and Elena’s is y = 20x + 10
Andre - 5x + 100 the x is how many weeks (6) so it’ll be 5(6) + 100 which is 30 + 100 = $130 in 6 weeks
Elena - 20x + 10 same thing x is how many weeks (6) as well so 20(6) + 10 which is 120 + 10 = $130 as well in 6 weeks so therefore, the answer is C.
Answer:
see below
Step-by-step explanation:
3y=6-2x and then
y=2-2/3x
Answer:
-16/3 = x
Step-by-step explanation:
3(x – 2) + 4x = 10(x + 1)
Distribute
3x -6 +4x = 10x+10
Combine like terms
7x-6 = 10x+10
Subtract 7x from each side
-6 = 3x+10
Subtract 10 from each side
-16 = 3x
Divide by 3
-16/3 = 3x/3
-16/3 = x
The perimeter of the triangle is : 12.6.
This result is obtain by the use of triangle perimeter formula :

Where : a is the distance between the points A and B
b is the distance between the points B and C
c is the distance between the points C and A
If they appear in one equation at the same time, you work on the numbers inside the parenthesis first then work on the numbers inside a bracket
