Answer:
x=130 (180-50)
y=50 (same)
a=135 (parellel)
b=45 (180-135)
c=45 (180-135)
d=135 (same)
Step-by-step explanation:
The answer is A because you need to find the unit rate of each cost
Since $2.80 is for 2 liters, do 2.80/2 which equals 1.4. So that’s the cost for one liter
Then, 6 half liter bottles is just 3 liters because 6*1/2= 3. Then to find the unit rate for that, do 3.90/3 which equals 1.3.
So the first option is $1.40 per liter and the second option is $1.30 per liter so the first option is more expensive- the 2-liter bottle, and the cost for that is 1.40
Hope this helps:))
Answer: 14.38%
Step-by-step explanation:
Worth of stock in Company A = $5990
Percent decrease = 20%
New worth = $5990 - (20% × $5990)
= $5990 - (0.2 × $5990)
= $5990 - $1198
= $4972
Worth of stock in Company B = $2450
Percent decrease = 8%
New worth = $2450 - (8% × $2450)
= $2450 - (0.08 × $2450)
= $2450 - $196
= $2254
Previous total worth = $5990 + $2450
= $8440
Total worth = $4972 + $2254
= $7226
The total percentage decrease in the investor's stock account will be:
= [($8440 - $7226) / $8440] × 100
=( $1214 / $8440) × 100
= 0.1438 × 100
= 14.38%
Answer:
see explanation
Step-by-step explanation:
(1)
p + q
= 2i - j + i + j ← collect like terms
= 3i
(2)
p - q
= 2i - j - (i + j) ← distribute parenthesis by - 1
= 2i - j - i - j ← collect like terms
= i - 2j
(3)
2p - 3q
= 2(2i - j) - 3(i + j) ← distribute parenthesis
= 4i - 2j - 3i - 3j ← collect like terms
= i - 5j
