Lissie set a goal to save $320 for a new computer. So far she has saved $112. What percent of her goal has Lissie saved so far?
Mariulka [41]
These are false. Tami will need to work 11 weeks to get to her goal. To find out this problem, first take out the 100 from the 320 which then gives you 220.  Then divide 220 by 20 which gives you 11. 1 is wrong because Tami does not have to work more than 21 weeks to get to her goal. 2 is also wrong because Tami does not need to save more that 11 weeks to get to her goal, she has to work 11 weeks only.

A) 4(x+1)=5x+12
mezya [45]
Hey there!

Here is ur answer >>>>

A) 4(X + 1 ) = 5x + 12

4x + 4 = 5x + 12

X = 4 - 12

X = -8

B) 13 ( 6 - x ) - 4 ( 3x + 12 ) = 0

78 - 13x - 12x - 48 = 0

30 - 25x = 0

30 = 25x

X = 30/25

X = 6/5

All of them are solved in these methods

Lin took 75 boxes of carrots and 80 boxes of potatoes to the market. She sold 68 boxes of carrots and 71 boxes of potatoes. How
enot [183]

For this case we have:

x: Represents the number of carrot boxes

y: Represents the number of boxes of potatoes

Initially we have:

x = 75\\y = 80

If you sold 68 boxes of carrot we have:

x = 75-68 = 7

If you sold 71 boxes of potatoes, we have:

y = 80-71 = 9

The number of boxes I take home is given by:x + y = 7 + 9 = 16

ANswer:

7 boxes of carrots left

There are 9 boxes of potatoes left

A total of 16 boxes remain
