A. Renard let’s t= the number of taffy bags and c= the number of Carmel bags. Help him write two equations to represent the info

vlabodo [156]

Answer:

20 taffy bags and 15 caramel candy bags

Step-by-step explanation:

<u>Given:</u>

t = the number of taffy bags
c = the number of caramel bags
Number of taffy's are 5 more than caramel bags
Taffy bags weigh 8 ounces and caramel bags weigh 16 ounces
Total weight is 400 ounces

<u>Equations:</u>

t = c + 5 (the difference in number of bags)
8t + 16c = 400 (the weight of the bags)

<u>Simplify the second equation by dividing all terms by 8:</u>

t + 2c = 50

<u>Substitute t and solve for c:</u>

c + 5 + 2c = 50
3c = 50 - 5
3c = 45
c = 45/3
c = 15

<u>Find the value of t:</u>

t = 15 + 5 = 20

<u>Answer:</u>

20 taffy bags and 15 caramel candy bags

What is the value of the expression

Y_Kistochka [10]

Answer:

0.8

Step-by-step explanation:

We begin with the expression: $0.5+(-\frac{3}{4} )+0.25-(-\frac{4}{5} )$

First, we need to convert the fractions into decimals to make this easier.

$-\frac{3}{4}=-0.75$ and $-\frac{4}{5} =-0.8$

Once we have this, we can simplify it

$0.5-0.75+0.25-(-0.8)\\\\0.5-0.75+0.25+0.8\\\\0.75-0.75+0.8\\\\0.8$
