Step-by-step explanation:
Answer:
A = 135
Step-by-step explanation:
The area of a triangle is found by
A = 1/2 bh
A = 1/2 (18)*15
A = 135
bearing in mind that standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient

Answer:
R=-12
Step-by-step explanation:
6(1 + 3R) = 2(10R - 9) -4R
Distribute 6 through the parentheses
6+18R=2(10R-9)-4R
Distribute 2 through the parentheses
6+18R=20R-18-4R
Collect like terms
6+18R=16R-18
Move the variable to the left-hand side and change its sign
6+18R-16R=-18
Move the constant to the right-hand side and change its sign
18R-16R=-18-6
Collect like terms
2R=-18-6
Calculate the difference
2R=-24
Divide both sides of the equation by 2
R=-12
if you'd make me brainliest that'd be great, if not its ok as well! I hope this helped!!!
Adult tickets + kids tickets = 120$
Y represents kids tickets
Z represents adult tickets
Z = twice kids tickets = 2Y
In ecuation:
Z + Y = 120$
Replace Z with 2Y
2Y + Y = 120 $
3Y= 120 / divided by 3
Y = 40$
You know the cost for 1 kid ticket
40 : 4 = 10 kids tickets sold
Z = 2x 40= 80$ for adult tickets
80:8 = 10 adult tickets sold
