Answer:
betty swam 21 jane swam 14
Step-by-step explanation:
You have 2 equations that are both equal to y. If they are both equal to y, then by the transitive property of equality, they are equal to each other (if a = b, and b = c, then a = c).
5x - 17 = x + 3 and
4x = 20 and x = 5. Now sub in that x value of 5 to solve for y:
y = 5 + 3 and y = 8. So the ordered pair is (5, 8)
Answer:
5/8
Step-by-step explanation:
1/4 (2/2)=2/8
3/8 (already simplified)
2/8+3/8=5/8
Answer:
b is 10 times greater
Step-by-step explanation:
If we multiply the first ratio by 2/2, we get 2/10. Since b=10 and c=1, b is 10 times greater.
