That's 2³ = 8 that gives the number of subsets
Answer:
318
Step-by-step explanation:
151+116+135+136+164+101+139=942
1260-942=318
3.8 liters times 1 is 1 gallon 3.8 liters times 39 is 39 gallons 3.8 times 39 is 148.2 liters
Y = 3/2x + 4
Add the 8 to both sides and then divide all the terms by 2
Answer:
11 cm, 19 cm, 27 cm
Step-by-step explanation:
Triangles have 3 sides and perimeter is the sum of all side lengths. So the equation is x + (2x-3) + (2x+5) = 57.
x + (2x-3) + (2x+5) = 57
x + 2x - 3 + 2x + 5 = 57
x + 2x + 2x - 3 + 5 = 57
5x + 2 = 57
5x = 57 -2
5x = 55
x = 11
Now that we know the value of x, we can figure out the side lengths. The first side (x) is 11 cm long, the second side (2x - 3) is 19 cm, and the third side (2x + 5) is 27 cm long.
