Answer:
an = 1/2 (n) (n+1)
Step-by-step explanation:
1,3,6,10,.........
3-1=2
6-3=3
Each term is different so there is no common difference. It is not an arithmetic sequence
3/1=3
6/3 =2
Each term is different so there is no common ratio. It is not a geometric sequence
1 3 6 10
+2 +3 +4
a1 = 1
a2 = 3
a3 = 6 = 2*3
a4 = 10 = 2*5
Move all terms not containing x to the right side of the inequality. You should get x<3
This is what your line should look like. The circle will be open because the is not line under the less than sign. And it will be going toward the left because it is less than greater than is graphed to the right.
Answer:
98
The answer is 98 because since the farmer's market sold 35% of its produce and has 280 peaches remaining you have to turn 35% into a decimal which is 0.35 then multiply that times 280 and get 98.
Answer:
x = 52
Step-by-step explanation:
The triangle is isosceles. The markings tell us that.
The 76 is not opposite either one of the equal sides. Let the angle values opposite the equal sides be x
x + x + 76 = 180 All triangles = 180
2x + 76 = 180 Subtract 76 from both sides.
2x = 180 - 76
2x = 104 Divide both sides by 2
x = 104/2
x = 52
So x = 52
