Mathematics
1 answer:
Elden [556K]3 years ago
4 0

Answer:

Shalini = 12

Poonam = 60

Step-by-step explanation:

Let p = poonams age

Let s = shalini's age

p = 5s

p+s = 72

Substitute the first equation into the second equation

5s+s = 72

Combine like terms

6s= 72

Divide by 6

6s/6 = 72/6

s = 12

p = 5s =5*12 = 60

Shalini = 12

Poonam = 60

A store had 112 diet sodas. The ratio of diet sodas to regular sodas was 8:4. How many regular sodas were there?
IceJOKER [234]

Answer:

56

Step-by-step explanation:

There are two ways the answer to this question can be determined

<u><em>Method 1 : the fast method </em></u>

We know that 8 is twice 4

4 x 2 = 8

The ratio of diet soda = 8

the ratio of regular sodas = 4

Diet sodas = 112

the number of regular sodas = 112 / 2 = 56

<u><em>Method 2 : The long method </em></u>

I would first determine the total number of diet and regular sodas. Let the total number be represented by d

from the question, the following equation can be derived :

(8/12) x d = 112

divide both sides of the equation by 12/8 to determine the value of d

d = 112 x (12/8) = 168

We can now derive a value for the number of regular soda

regular sodas = ( ratio of regular sodas / total soda) x total number of sodas

(4/12) x 168 = 56

lesantik [10]

Answer:

A. The solution set is x = 5 or -7

Step-by-step explanation:

\sqrt[4]{ {x}^{2} + 2x }  =  \sqrt[4]{35}  \\ {({x}^{2} + 2x) }^{ \frac{1}{4} }  =  {(35)}^{ \frac{1}{4} }  \\ {x}^{ \frac{1}{2} } + {2x}^{ \frac{1}{4} }   =  {35}^{ \frac{1}{4} }  \\   {x}^{2}  + 2x = 35 \\  {x}^{2}  + 2x  -  35 = 0 \\ (x - 5)(x + 7) = 0 \\ x = 5  \: or \:  - 7

Therefore, the answer is A. as the solution is x = 5 or -7
