How you find the area of a triangle is base × height ÷ 2. So the equation would be 6×3=18 18÷2=9, so the answer is 9. Hope this helped!
x=smaller number
y=larger number
x+y=12
y=3x-6
Let's begin with the first equation...
x+y=12
Let's substitute...
x+(3x-6)=12
4x-6=12
Let's add 6 to both sides as we proceed to isolate x...
6+4x-6=12+6
4x=18
Let's divide both sides by 4...
(4x)/4=18/4
x=9/2=4.5---smaller number
12-4.5=7.5s larger number

m = 80
Step-by-step explanation:
40 = ( multiply both sides by 2 )
80 = m
Answer:
30 hours
Step-by-step explanation:
Given that:
Mai = $7 per hour
Priya = $8.50 per hour
Mai's initial amount = $15
Number of hours when they'll both have the same amount
Let number of hours = x
15 + 7x = 8.50x
15 = 8.50x - 7x
15 = 0.5x
x = 30
they'll both have the same amount in 30 hours
