The answer is D.

If you multiply them all together the answer (without simplifying), it should equal 210/9, you then simplify the numerator and denominator by 3 and you get 70/3.

Answer:

Step-by-step explanation:

Given

$\frac{5}{3}$ × $\frac{2}{3}$ × $\frac{21}{1}$

Multiply numerators/ denominators

= $\frac{5(2)(21)}{3(3)(1)}$

= $\frac{210}{9}$

Cancel the numerator/denominator by dividing both by 3

= $\frac{70}{3}$ → D

melisa1 [442]

Answer:

A) 5x + 2y = 22

B) -2x + 6y = 3 We'll multiply A) by -3

A) -15x -6y = -66 Then we'll add B)

B) -2x + 6y = 3

-17x = -63

x = 3.7058823529
