Answer:
Diana has 33 and Roberto has 15.
Step-by-step explanation:
Use D for the amount of apples Diana has and R for Roberto
D=R+18
D+R=48
Use Substitution to solve the system of Equations
R+18+R=48 ----> 2R+18=48- Subtract 18
2R=30- DIvide by 2
R=15
Substitute R into another equation
D=R+18
D=15+18
D=33
Answer:
9.425 or 3π
Step-by-step explanation:
arc length = 2πr(θ/360)
The angle is 90˚ as indicated by the square symbol.
ABC = 2π6(90/360) = 9.425 or 3π
This line through M and parallel to BC is the <span>average line of BC. So this lane goes through the midpoint of AC that is N. And we have the length of AN=1/2AC=3/2</span>
The third and fourth options.
The answere is 213 boxes
If you add 3 dozens to 14 dozens of boxes of envilopes , then you get 17 dozens of boxes of envilopes.Then of you sum up the 1/2 (2/4 ) with the 1/4.You get 3/4. Finally, you add 17 dozens to 3/4 of a dozen you get 17 3/4 dozens( wich is 213 boxes )
