Answer: 9 packs
Step-by-step explanation:
- Mrs. Marks wants 89 pens.
- Pens come in packs of 10
89 is about 90. The pens come in packs of 10, so divide 90 by 10 and the quotient is 9.
The ratio equivalent to 6 : 32 can be determined by determining the greatest common factor of the two numbers. In this case, the greatest common factor of 6 and 32 is equal to 2. Hence we divide each number by 2. The answer to this problem is 3 : 16.
The answer is 2.
3x+2y=3
2x-2y=7
solve both the equations
3x+2y=3
+2x-2y=7
5x=10
so we get
x=2
Answer:
117
Step-by-step explanation:
Given the expression
r³ - 2s ← substitute given values into the expression
= 5³ - 2(4)
= 125 - 8
= 117
