In hopes of encouraging healthier snacks at school, Leah brought in a tray of carrot sticks
aleksandr82 [10.1K]

Answer:

40 %  of the snacks were carrot sticks.

Step-by-step explanation:

Total number of carrot sticks in lunch = 18

Total number of apple slices in lunch = 27

So, Total Snacks in the Lunch = Carrot Sticks + Apple Slices

                                                   = 18 +  27 = 45

Now, \textrm{Percentage of Carrot Sticks}  = \frac{\textrm{The number of Carrot sticks in lunch}}{\textrm{Total snacks in the lunch}}  \times 100

= \frac{18}{45}  \times100 = 40

⇒Percentage of Carrot Sticks = 40%

Hence, 40 %  of the snacks were carrot sticks.

Step-by-step explanation:

-3x+7=-8

Bring 7 to the other side, it becomes negative

-3x=-8-7

Signs are same on rhs so u add

-3x = -8+-7= -15

Bring -3 to the other side n divide

therefore,

x=-15/-3

= +5 (two negatives become positive)

Hope it helps!

julia-pushkina [17]
----------------------------------------------------------------------------
Find total number of integers
----------------------------------------------------------------------------
Number of integers from 1 to 100 = 100
There are 100 numbers altogether

----------------------------------------------------------------------------
Find total numbers that can be divided by 2
----------------------------------------------------------------------------
Number that are multiples of 2 = 100 ÷ 2 = 50
50 of the number are multiples of  2

----------------------------------------------------------------------------
Find total numbers that are multiples of 3
----------------------------------------------------------------------------
Numbers that are multiples of 3 = 100 ÷ 3 = 33 R 1
33 of the numbers are multiples of 3

Of the 33 numbers that are multiples of 3, half of the numbers are even and had been included in multiples of 2.
33 ÷ 2 = 16 R 1

33 - 16 = 17
17 of the numbers are multiples of 3

----------------------------------------------------------------------------
Total numbers that can be multiples of 2 or 3
----------------------------------------------------------------------------
50 + 17 = 67

----------------------------------------------------------------------------
Total number that are neither multiples of 2 nor 3
----------------------------------------------------------------------------
100 - 67 = 33

----------------------------------------------------------------------------
Ans: 33 integers are neither multiples of 2 nor multiples  3
