Answer:
perimeter is 12x-6
Step-by-step explanation:
perimeter is the sum of all sides
3(x+2) + 2x+11 + 7x-23
distribute the 3 in the first term, then combine 'like terms'
3x+6 + 2x+11 + 7x-23
3x+2x+7x + 6+11+(-23)
12x-6
So J is jelly beans and T is trail mix :)
so J= $3.50
T= $1.50
The formula for finding the area of an equilateral triangle is
square root of 3 * (a^2/2)
a is the side length so in this case is 6
square root of 3 * (18)
the area is about 15.6
Answer:
slope is 0
Step-by-step explanation:
Answer:
Jimmy has a ratio of 1:20, or 1 page:20 seconds. Carlo has a ratio of 1:30, or 1 page:30 seconds. Jimmy reads at a faster pace than Carlo, as he is able to read a page in 2/3 of the time it takes Carlo.
Step-by-step explanation:
Jimmy reads a page, on average, every 20 seconds.
5 × 60 = 300
300/15 = 20
therefore, one page every 20 seconds
1:20
Carlo reads a page, on average, every 30 seconds.
6 × 60 = 360
360/12 = 30
therefore, one page every 30 seconds
1:30
