A parking lot has 21 empty space. if the ratio of empty spaces to taken spaces is 7:5 how many dpaces are there total?

1 answer:

5 0

$\frac{empty}{taken} = \frac{7}{5} = \frac{21}{x} 


$

x=(5*21)/7=15 taken spaces

total =empty spaces+taken spaces= 21+15=36

Evaluate the expression. 7.2 + 6.3(5.4 – 6)

REY [17]

$\text{Hey there!}$

$\text{Evaluate the expression: 7.2 + 6.3(5.4 - 6)}$

$\mathsf{7.2+6.3(5.4-6)}\\\\\mathsf{5.4 -6=-0.6}\\\\\mathsf{7.2+6.3(-0.6)}\\\\\mathsf{6.3(-0.6)=-3.78}\\\\\mathsf{7.2 - 3.78= \underline{3.42}}\\\\\boxed{\boxed{\mathsf{Answer:3.42}}}\checkmark$
