Hello,
Let's assume a the age of Bea
b the age of her sister
This year: a+b=18
Next year (a+1)+(b+1)=(a+b)+(1+1)=(a+b)+2=18+2=20
The answer is D.) 23. First you subtract 12 from both sides of the equation. You will get 0.35x=8.05. Then you divide both sides by 0.35 to get x=23.
Answer: 76.5 I'm assuming the question is asking for the answer of 3(2+100)/4
Step-by-step explanation:
3(2+100) would become 3x102 which is 306 and when you divide it by 4 it becomes 76.5
Answer:
C. 70 mi
Step-by-step explanation:
42+56= 98
98 is the distance is from Ferris to Dunlap to Buttle.
To find the distance directly from Ferris to Buttle, you have to use a^2+b^2=C^2.
42^2+56^2=c^2
1,764+3,136=c^2
√4,900=√c^2
70=c
Answer:
.9167 miles per lap
Step-by-step explanation:
