1 answer:

3 0

Use distribution
-5t - 30 + 7t = 100

Add 30 to both sides
2t = 130, t = 65
Solution: t = 65

Adante begins to evaluate the expression 3 1/3 x 5 1/4 using the steps below

il63 [147K]

Answer:

$\frac{35}{2}$

Step-by-step explanation:

To solve this problem we need to write the mixed fraction as a fractional number, as follows:

$3 1/3 = 3 + \frac{1}{3} = \frac{9+1}{3} = \frac{10}{3}$

$5 1/4 = 5 + \frac{1}{4} = \frac{20+1}{4} = \frac{21}{4}$

Then, evaluating the expression:

$\frac{10}{3}$ × $\frac{21}{4}$ = $\frac{210}{12}$ = $\frac{35}{2}$
