Answer:
The answer is 75 and 85.
Step-by-step explanation:
If the instrument measures in units of 10, then the measurement could be 5 units on either side of 80 (80 − 5 = 75, 80 + 5 = 85). Any value between 75 and 85 would be measured as 80.
First, let's ignore the answer choices and solve for a value of x ourselves.
2(8 - x) < 4
Distributive property.
16 - 2x < 4
Subtract 16 from both sides.
-2x < -12
Divide both sides by -2 (and flip the inequality sign)
x > 6
The value of x is going to be greater than 6, and so, we can observe the answer choices, and whichever value is greater than 6, is the correct answer.
<h3>In this case, there is only one answer, and that is D, x = 10.</h3>
common difference is calculated by subtracting previous term from next term
So
3) common difference = 8-4 = 4

4) common difference = 7-6.3 = 0.7

5) common difference = 500-200 = 300
Answer:
216 cubic meters
Step-by-step explanation:
to find the volume of any prism the equation is bh or base times height
the base is a triangle so you find the triangles area and multiply it by the height
8 * 6 * 1/2 = 24
24 * 9 = 216
216 cubic meters
Answer:
JL = 62
Step-by-step explanation:
JL = JK + KL, substitute values
5x + 2 = 27 + 3x - 1
5x + 2 = 26 + 3x ( subtract 3x from both sides )
2x + 2 = 26 ( subtract 2 from both sides )
2x = 24 ( divide both sides by 2 )
x = 12
Thus
JL = 5x + 2 = 5(12) + 2 = 60 + 2 = 62
