Look below
Step-by-step explanation:
First you multiply the top and bottom
5/12 x 6/7
5x6 and 12x7
you get your new fraction of 30/84
then you simplify it by 6 to get 5/14
hope this helps
Answer:
21 and 28
Step-by-step explanation:
1) calling the smaller number x and the larger y we can write two equations.
x+y=49 and y+2x=70
2) by reordering the first to read x= 49-y we can then plug it in as the x in the second equation.
y+2(49-y)=70
3) we can then distribute
y+98-2y= 70
and then simplify
y=28
4) then we need to plug y back into the first equation to find the value of x
x+(28)=49
-28 -28
x = 21
5) the numbers are 21 and 28

Answer:
Y = 16a + 12b
Step-by-step explanation:
Given:
Cost of each neckless = $16
Cost of each bracelet = $12
Find:
Equation for the following state
Computation:
Assume;
Number of neckless sale in a month = a
Number of bracelet sale in a month = b
Total amount she earn = Y
So,
Total amount she earn = (Cost of each neckless)(Number of neckless sale in a month) + (Cost of each bracelet)(Number of bracelet sale in a month)
Y = (16)(a) + (12)(b)
Y = 16a + 12b
