Answer:
2 - 4b
Step-by-step explanation:
The terms in the expression are unlike; therefore they can't be combined. This means that the expression is already simplified.
X represent the number of laps Marcy swam, 1 1/4x represent the number of times Toni swam.
20 + 0.80(1 1/4x) + 15 + 0.85x = 257
20 + x + 15 + 0.85x = 257
1.85x + 35 = 257
Required equation is 1.85x + 35 = 257

Answer: t - 0.1t and 0.9t
Step-by-step explanation:
Let the original acreage be represented by t.
Since there was a sale which ended up reducing the acreage by 10%, the expression for the new acreage will be:
= t - (10% × t)
= t - (0.1 × t)
= t - 0.1t
= 0.9t
Therefore, the equivalent expressions will be "t - 0.1t" and 0.9t
