Answer:
240
Step-by-step explanation:
If you draw a straight line, 12 would meet at 240. Hope this is helpful! You were close but I think you mixed up 240 and 300.
Area= a*height
the formula for an isosceles trapezoid is 1/2(base1+base2)*height. 1/2 base 2 and 2a will simplify to a base length of a. a times height or a*height
Answer:
$2.97
Step-by-step explanation:
The answer is n=28;
1. Subtract 14 from both sides (-n/2 = -14)
2. Multiply by 2 on both sides to get rid of the fraction (-n = -28)
3. Divide by -1 to get n by itself (n = 28)
You could also eliminate step three by multiplying by -2 instead of just 2.
Hope this helps!
Answer:
Step-by-step explanation:
Givens
Let the least number = x
Let the largest number = 2x
Let the second number = x + 3
The sum = 75
Equation
x + 2x + x + 3 = 75 Combine the terms on the left
Solution
4x + 3 = 75 Subtract 3 from both sides
4x +3-3= 75-3
4x = 72 Divide by 4
4x/4 = 72/4
x = 18
Answer
Smallest number = 18
Second number = 18 + 3 = 21
Largest number = 2*18 = 36
Sum = 75
