Answer: 25
Step-by-step explanation:
To find the mean, you have to add up all the number then divide the result by how many number there are:
6 + 2 + 59 + 12 + 11 + 9 + 9 + 54 + 54 + 46 + 2 + 32 + 43 + 11 = 350
then, 350 ÷ 14 = 25
10a+3+2a=39
12a+3=39
-3 -3
12a=36
/12 /12
a=3
X, x+1, x+2, x+3 are 4 consecutive integers
2(x + x+2) = 5(x+3) - 26
2(2x+2) = 5(x+3) - 26
4x + 4 = 5x + 15 - 26
4x + 4 = 5x - 11
15 = x
15, 16, 17, 18
x, x+2, x+4 consecutive even integers
2(x+4)+11 = x + 9
2x + 8 + 11 = x + 9
2x + 19 = x + 9
x = -10
-10, -8, -6
Answer: x = -44/7
Step-by-step explanation:
Step 1: Subtract 3 from both sides.
7x+3−3=−41−3
7x=−44
Step 2: Divide both sides by 7.
7x/7 = -44/7
Answer:
-44/7
