The expression is:


The result is:

-4 - (-36) = -4 + 36 = 32 units
Answer:
- 4 4/5 *C
Step-by-step explanation:
12:00-6:00 is 6hrs
7/10*6 = 42/10 = 4 1/5
1 - 4 1/5 = - 4 4/5
The first thing you should know is that the rate of each one is:
Kaitlyn = 1/6
Mark = 1/8
Then,
d = number of days.
The equation then if they work together is:
1 / 6d + 1 / 8d = 1
answer:
the equation for number of days it would take to build the sheld together is
1 / 6d + 1 / 8d = 1
Answer:
Step-by-step explanation:
for odd terms
first term=5
c.d.=8-5=3
odd terms are given by 5+3(n-1)=2+3n
for even terms
first term=10
c.d.=13-10=3
even terms are given by 10+3(n-1)=7+3n
