Step-by-step explanation:
hope this helps
Let
R = Ralph's age
S = Sara's age
First statement is translated as:
S = 3R
Second statement is translated as:
S + 4 = 2(R + 4)
Use the first equation to be substituted into the second one in terms of R which is the one we are actually going to solve for Ralph's age.
Since S = 3R, then
3R + 4 = 2(R + 4)
3R + 4 = 2R + 8
3R - 2R = 8 - 4
R = 4 years old
2. 4/6 , 6/9
3. 2/4 , 3/6
4. 8/10 , 12/15
5. =
6. >
7. >
8. =
9. =
10. <
11. =
12.
Answer:
i think it's <C and <R since they're 90 degree angles, though they are small
