Answer:
18. g= -3
19. x= -1
20. n= 3
21. p= -1
22. d= -3
23. a= 5
Step-by-step explanation:
how to solve the variable (using 18 as an example)
step 1: simplify both sides of the equation.
20+g+g=14
(g+g)+(20)=14(combine like terms)
2g+20=14
2g+20=14
step 2: subtract 20 from both sides.
2g+20−20=14−20
2g=−6
step 3: divide both sides by 2.
2g/2 = -6/2
Answer:
Step-by-step explanation:
P(a or b) = P(a) + P(b) - P(a and b)
0.88 = 0.70 + 0.60 - P(a and b)
P(a and b) = 1.30 - 0.88 = 0.42.
So the events a and b are not mutually exclusive.
Answer:
b
Step-by-step explanation:
A^2 + B^2 = C^2 - Right Triangle Formula
8^2 + 7^2 = 6^2 - Plug it into the formula
64 + 49 = 36 - Solve
64 = 85 - Add B and C
21 - your answer
Hopefully this helps.
Ok, so here, we have the unit rate of the snail. Now, we need to set up a proportion.
60/1 = 120/x
Now, cross multiply.
60*x = 120*1
60x= 120
Now divide to solve for x.
60x/60 = 120/60
x = 120/60
x= 2
Now our final answer is 2.
Final answer:- The snail will take 2 minutes to crawl 120 feet
