Anna, Elisa and Tiara are selling candy bars to raise money for the track team. The ratio of candy bars sold by Anna, Elisa and

andreev551 [17]

Number of candy bars sold by girls altogether is 91

<h3>Solution:</h3>

Given that The ratio of candy bars sold by Anna, Elisa and Tiara are 2 to 4 to 7

So ratio of candy bars sold by Anna, Elisa and Tiara = 2 : 4 : 7

Let the candy bars sold by Anna be 2a

Let the candy bars sold by Elisa be 4a

Let the candy bars sold by Tiara be 7a

Given that Elisa has sold 28 candy bars

Number of candy bars sold by Elisa = 28

4a = 28

a = 7

So we have found "a" as 7

Thus we get,

candy bars sold by Anna = 2a = 2(7) = 14

candy bars sold by Elisa = 4a = 4(7) = 28

candy bars sold by Tiara = 7a = 7(7) = 49

We have to find the number of candy bars sold by girls altogether

number of candy bars sold by girls altogether = candy bars sold by Anna + candy bars sold by Elisa + candy bars sold by Tiara

number of candy bars sold by girls altogether = 14 + 28 + 49 = 91

So altogether girls sold 91 candies

Evaluate the numerical expression. (5 + 3) x 2 - 6 please help!

Nuetrik [128]

Answer:

Step-by-step explanation:

Please use " * " or " · " to indicate multiplication; " x " is a variable, not an operator.

(5 + 3) x 2 - 6 => (5 + 3)·2 - 6

Order of operations rules require that we do first any work inside parentheses. So we have:

(5 + 3)·2 - 6 => (8)·2 - 6

Those same rules dictate that we must multiply before subtracting. So now we obtain:

16 - 6 = 10
