lesya [120]

Answer:

11/12

Step-by-step explanation:

Fraction of smoothie that is Banana = 1/4

Fraction of smoothie that is strawberry = 2/3

The fraction of smoothies that were either banana or strawberry

= 1/4 + 2/3

Least Common Denominator= 12

= (3 × 1 + 2 × 4)/12

= 3 + 8/12

= 11/12

The fraction of smoothies were either banana or strawberry is 11/12

X=a/b , x =4 and b=2 solve for a

lisov135 [29]

X = a/b

4 = a/2
multiply both sides by 2 to isolate the variable

a = 8

Bror cancelled terms which should NEVER be done.
x² + 3x + 2 / (x + 2) =
(x+1) * (x+2) / (x+2)

Cancelling the (x+2) factor we get
x + 1

Find the sum of the numbers divisible by 7 between 30 and 500

brilliants [131]

Answer:

17822

Step-by-step explanation:

The number that are divisible by 7 between 30 and 500 are as follows :

35, 42,49,.....,497

It will form an AP with first term, a = 35 and common difference, d = 7

Let there are n terms in the AP.

nth term of an AP is given by :

$a_n=a+(n-1)d$

Putting all the values,

$497=35+(n-1)7\\\\462=(n-1)7\\\\n-1=66\\\\n=67$

Now, the sum of n terms of an AP is given by :

$S_n=\dfrac{n}{2}[2a+(n-1)d]$

Putting all the values,

$S_n=\dfrac{67}{2}[2(35)+(67-1)7]\\\\S_n=17822$

Hence, the sum of the numbers that are divisible by 7 between 30 and 500 is 17822.
