i) u + 3 V
1 by 2 + 3 *minus 2
1 by 2 -6
1 - 12 by 2
- 11 by 2
ii) - 3 * 1 by 2 + 2 * -2 + 3 by 4
minus 19 by 4
Get total lengths by multiplying:
10 x 12.6 = 126
6 x 16.1 = 96.6
Add the total lengths together and divide by 16:
126 + 96.6 = 222.6
222.6 / 16 = 13.9125
Rounded to 2 decimal places = 13.91
answer: 13.91

Answer:
a=-8
b=-29
Step-by-step explanation:
Let's assume
first number is a
second number is b
the difference of two numbers,a and b,is 21
so, we get

we can solve for 'a'

the difference of five times a and two times b is 18
so, we get

now, we can plug 'a'

now, we can solve for b




now, we can find 'a'
