Answer:
15.75
Step-by-step explanation:
first add
12+25+16+9+5+22+27+20=126
then divide by how ever many numbers there are in this case there's 8:
126÷8=15.75
Answer:
<h3>
m∠B = 26°</h3>
Step-by-step explanation:
∠A and ∠B being complementary means m∠A + m∠B = 90°
4x + 24 + 3x - 4 = 90
7x + 20 = 90
7x = 70
x = 10
m∠B = (3•10 - 4)° = 26°
Answer:
OPTION A
Step-by-step explanation:
The first term in the Arithmetic progression is f(1) = 3.
The general term is given to be: f(n) = f(n - 1) - 2
Therefore, to find second term, simply substitute n = 2 and so on.
So, Second term = f(2) = f(2 - 1) - 2
⇒ f(2) = f(1) - 2
= 3 - 2
= -1
Third term: n = 3
⇒ f(3) = f(3 - 1) - 2
= f(2) - 2
= -1 - 2
= - 3
Similarly, fourth term, f(4) = f(3) - 2
= - 3 - 2
= -5
And fifth term f(5) = f(4) - 2
= - 5 - 2
= - 7
Hence, OPTION A is the answer.
Answer:
255
Step-by-step explanation:
Given :
Simplify the expression :
25(0.3x-4)-5(1.5x-6)+100(13/4)
Open each Bracket:
7.5x - 100 - 7.5x + 30 + 325
7.5x - 7.5x - 100 + 30 + 325
= 255
The simplified equation = 255
