Answer:
C. 2c+12
Step-by-step explanation:
"12 more than 2 times the number of cats" means "12 + 2c", where c is the number of cats.
To get 2 times, we multiply by 2. To get 12 more, we add 12.
We are given : Cost of a gallon of milk = $2.50.
Cost of a cup of yogurt = $1.20.
Total money Monica has = $20.
Number of cups of yogurt Monica can buy = x.
And inequality made is also correct
1.20x + 2.5 ≤ 20.
Now, we need to solve it for x.
Subtracting 2.5 from both sides, we get
1.20x + 2.5 -2.5 ≤ 20 - 2.5.
1.20x ≤ 17.5
Dividing both sides by 1.20, we get
1.20x/1.20 ≤ 17.5/1.20.
x ≤ 14.5833...
Because it's less than 15, so final answer is : 14 is greatest number of cups of yogurt Monica can buy.
Answer:
B
Step-by-step explanation:
Please see the answer in the picture attached below.
" From Step 1: We find that Angle N1 equals to 75 gradius => Answers A and C wrong. Answers B and D are left.
" From Step 4: We find that Angle N2 equals to 129 gradius => Answer B is true.
You don't need to find the exact value of the angle N3 in oder to choose the right answers from A,B,C,D.
Hope this answer can help you. Have a nice day!
Answer:
cost when 400 miles is driven is $143.
Step-by-step explanation:
Model for cost calculation: C=0.32m + 15
We have to find cost when no. of miles driven is 400.
To find that cost we need to plug 400 in place of m.
C=0.32m + 15
=> c = 0.32*400 + 15
=> c = 128 + 15 = 143
Thus, cost when 400 miles is driven is $143.
