Answer:
5(25 + z)
Step-by-step explanation:
(100+4z)20 can be reduced, since 4 divides evenly into 100, 4 and 20:
(25 + z)(5), or 5(25 + z).
This result can be left as is, or rewritten as 125 + 5z.
Answer:
5
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√(-2 - 2)² + (5 - 2)²
√(-4)² + (3)²
√16 + 9
√25
= 5
Answer: 6cups of flour
Step-by-step explanation:
3cups of sugar to 2cups of flour
9cups of sugar to xcups of flour
Let sugar rep s
Flour rep f
So we have;
3s=2f
9s= xf
Cross multiply
3s×xf=2f×9s
Xf=2f×9s/3s
Xf=6f
Therefore, 9cups of sugar will be to 6cups of flour
Answer:
Mark is 9 years old.
Step-by-step explanation:
If Mark Bro is 5 years older and combined is 23, then you want to subtract 5 from 23 giving you 18. Now since there is mark and his brother that is 2. So divide 18 by 2 and you get 9. Mark is 9. Add 5 to the other 9 because mark is 9 and we divided by two so one nine still remains you get (14). Now you can check. Marks age plus his brothers 9+14=23.
Equation: mark=m
m = (23-5)/2
m=18/2
m=9
