Answer:
The cost of 7.5 lbs of chopped walnuts is $25.875
Step-by-step explanation:
we are given
It costs $3.45 to buy lb of chopped walnuts
so,
1 lb of chopped walnuts = $3.45
now, we can multiply both sides by 7.5
so, we get
7.5 lbs of chopped walnuts = $25.875
So, the cost of 7.5 lbs of chopped walnuts is $25.875
The answer is C. I just divided the pages read by the time it took to read it.
For example: Fiona read 45 pages in 3 hours. 45 divided by 3 equals 15. Then, Albert read 30 pages in 6 hours. 30 divided by 6 equals 5.
Given that the first mass of the duck is 0.05 kg and it gains weight at a rate of 0.042 kg/week, the equation that would represent this scenario is,
y = 0.05 + 0.042x
where y is weight and x is the number of weeks. To determine the number of weeks in which the duck's mass becomes 0.890,
0.890 = 0.05 + 0.042x
The value of x from the equation is 20.
#2. 32 3/4 - 12 1/2 =
= 32 3/4 - 12 2/4 =
= 20 1/4
#3. 517 37/ 50 + 312 3/100 =
= 517 74/100 + 312 3/100 =
= 829 77/100
#4. 632 16/25 + 32 3/10 =
= 632 32/50 + 32 15/50 =
= 664 47/50
#5. 421 3/50 - 212 9/10 =
= 421 3/50 - 212 45/50 =
= 208 4/25
