Answer: So our equation is 
Laura does:

while Sean does:

So sean sums four times the number 2/3, while Laura sums two times the number 4/3, this is because we are working with a multiplication, and the order of the factors does not alter the product.
The two are splitting the equations in different ways.
Answer:
43 15/22 degrees
Step-by-step explanation:
The three angles add to 180 degrees
7x+6 +10x-8 + 5x+3 = 180
Combine like terms
22x +1 = 180
Subtract 1 from each side
22x +1-1 =180-1
22x = 179
Divide each side by 22
22x/22 = 179 /22
x =179/22
The smallest angle is
5x+3
5(179/22) +3
895/22 +3
40 15/22 +3
43 15/22 degrees
Answer:
The percentage of decrease is approximately 0.14%.
Step-by-step explanation:
35 - 5 = 30
What percentage is 5 of 35 (x/100 = is/of)
x/100 = 5/35 (cross multiply)
(5*100)/35 = 14.29%
Answer:
300-150
Step-by-step explanation:
300 deposited into bank account (+)
150 taken out of bank account (-)
Zero of divisor (x+2) is -2
Now putting the value of x as -2,
