Answer:
I believe the answer to this question is: B.
Answer:
y=
x=
Step-by-step explanation:
7x+4+12x+24=180
19x+28=180
19x=180-28
19x=152°
19x/19=152/19
x=8
y=7x+4
y=7*8+4
y=60°
To get percentage u take the percent u are trying find and divide it by 100 like 98percent and u get .98 then u would multiply .98 by 192 and u get 188.16 u do the same with the next two and u get 66.34 , 39.48
Answer:
Method 2:
⇒(1,000-10)×(30+7)
=1,000×(30+7)-10×(30+7)
=30,000+7,000-300-70
=37,000-370
=36,630
Method 1:
990×(40-3)
=990×40-990×3
=39,600 -2970
=36,630
Given:
The nth term of a number sequence is
.
To find:
The first 3 terms and the 10th term.
Solution:
We have, nth term of a number sequence.

For n=1,



For n=2,



For n=3,



For n=10,



Therefore, the first three terms are 3, 8 and 15 respectively. The 10th term is 120.
