Answer:
[3x + (y/2)]
Step-by-step explanation:
English Translation
Suppose we have x confirmed cases of coronavirus and y suspected cases. A - If the confirmed cases triple and half of the suspects fall, we will have the following expression to represent the total number of cases:
Solution
Number of confirmed cases = x
Number of suspected cases = y
Number of confirmed cases triples and becomes 3x
Half of the suspected cases fall and becomes (y/2)
Total number of cases then becomes
[3x + (y/2)]
In Portugese/Em português
Número de casos confirmados = x
Número de casos suspeitos = y
O número de casos confirmados triplica e se torna 3x
Metade dos casos suspeitos cai e se torna (y / 2)
O número total de casos passa a ser
[3x + (y / 2)]

The answer would be 747.50! Because if you were wanting to decrease the price then you would multiply $299 by 40% So since you are wanting to add to the price then you would divide...Hope that makes since :)
Answer:
7/10
Step-by-step explanation:
67/10-60/10=7/10
Step-by-step explanation:
a) substitute x values:
6-2(0) = 6
6-2(1) = 4
6-2(2) = 2
6-2(3) = 0
6-2(4) = -2
6-2(5) = -4
b) rewrite equation as y=-2x+6.
this shows a negative slope with a y-intercept of 6.
c) 3=6-2x
-6 -6
-3 = -2x
divide both sided by 2
-3/-2 = x
3/2=x
Answer:
hence Robert runs at a faster speed
Step-by-step explanation:
1 1/2 hours = 3/2 hours = 1.5 hours
45 min = 45/60 = 3/4 = 0.75 hours
Jacob's speed = 5 miles ÷ 1.5 hours = 3.33 miles/hr
Robert's speed = 3 miles ÷ 0.75 hours = 4 miles/hr
hence Robert runs at a faster speed
