Answer:
Maria's book was 8 days late
Step-by-step explanation:
According to the information given, you can write an equation that states that 15¢ multiply for the number of days that the book was late plus $2 is equal to $3.20:
0.15x+2= 3.20
x= number of days that the book was late
Now, you have to solve for x:
0.15x= 3.20-2
0.15x= 1.20
x= 1.20/0.15
x= 8
The book was 8 days late.
Answer: 6
Step-by-step explanation:
One of the triangular faces is 4*3= 12. Then 1/2 of 12 is 6.
<span>2(11r + 7) + 1 = 1/4 (88r+60)
</span><span>22r + 14 + 1 = 22r + 15 ---------------------->distributive property
simplify
22r + 15 = 22r + 15
0 = 0
answer: infinite solutions</span>
Answer:
10) 1/11
11) 18/8 or 2 2/8 or 2 1/4
12) -8/5 or -1 3/5
Step-by-step explanation:
10) -6/11-(-5/11)=-6/11+(5/11)=<em>1/11</em>
11) 1 3/8-(-7/8)=11/8+7/8=18/8 or 2 2/8 or 2 1/4
12) -4/5-4/5=-8/5 or -1 3/5
