n, n + 2, n + 4 - three consecutive odd integers
The equation:
2n = 3(n + 4) + 15 |use distributive property
2n = (3)(n) + (3)(4) + 15
2n = 3n + 12 + 15
2n = 3n + 27 |subtract 3n from both sides
-n = 27 |change the signs
n = -27
n + 2 = -27 + 2 = -25
n + 4 = -27 + 4 = -23
Answer: -27, -25, -23.
Answer:
<u>a₂₀ = 60</u>
Step-by-step explanation:
<u>Given :-</u>
a₃ = 9
a₈ = 24
<u>To find :-</u>
a₂₀
<u>Solving :-</u>
Expand the given values.
a + 2d = 9 -(1)
a + 7d = 24 -(2)
Now subtract (1) from (2).
=> 5d = 15
=> d = 3
a = 9 - 2d
a = 9 - 6
a = 3
<u>Final answer :-</u>
a₂₀
= a + 19d
= 3 + 19(3)
= 3+ 57
= 60
<u>a₂₀ = 60</u>
Answer:
-0.3*0.2*12, multiply -0.3 by 0.2 to get -0.06, now multiply 12 by it to get, -0.72.
Step-by-step explanation:
Answer:
12=3x+4y in slope-intercept form is y=-3/4x+3 and the slope that's negative is the first one so therefore it's the first one.
