Jane and her friends were selling cookies. They sold 4 more boxes the second week than they did the first. On the third week, th
algol13

Step-by-step explanation:

let the number of cookies sold on first week be=x

let the number of cookies sold on second week be= x+4

let the number of cookies sold on third week be= (x+4)×2

total number of cookies sold = 351

now 351=(x)+(x+4)+(x+4)×2

351=3x+(4+4×2)

351=3x+12

3x=351-12

3x=339

x=339÷3

x=11

Cookies sold on first week=113

Cookies sold on second week= 113+4= 117

Cookies sold on third week =113+4×2 = 113+8=121

now add all the number of cookies solved for confirmation
=113+ 117+ 121= 351

In a 650g bag of mixed dried fruits, the ratio of mangos to apples to pears is 12:8:6 by mass. Determine the masses of the mango
Virty [35]

Answer:

mass of mangos = 300g

mass of apples = 200g

mass of pears = 150g

Step-by-step explanation:

lets first reduce the ratio

12:8:6

is the same as

6:4:3

this means the the denominator of our fractions will be 6 + 4 + 3 = 13

hence

mangos = 6/13 of 650g

6/13 * 650 = 300

apples = 4/13 of 650g

4/13 * 650 = 200

pears = 3/13 of 650g

3/13 * 650 = 150
