Answer:
PA GEN SOLISYON --> "NO SOLUTION"
Step-by-step explanation:
Whether you multiply the top equation by ⅓ to make "-y" and "2x", or multiply the bottom equation by 3 to make "3y" and "-6x", you will see that 9⅓ ≠ 0, or 24 ≠ 0, therefore the result is "NO SOLUTION".
X represent the number of laps Marcy swam, 114x represent the number of times Toni swam.
20 + 0.80(114x) + 15 + 0.85x = 257
20 + 91.2x + 15 + 0.85x = 257
92.05x + 35 = 257
Required equation is 92.05x + 35 = 257
Answer:
PR=8
ST=5
Step-by-step explanation:
2x=8
x=4
PR=2x=8
5z=2z+3
3z=3
z=1
ST=5z=5
Because the ones place is under 5, we round down, and 392 becomes 390 when rounded to the nearest 10
