Answer:
x>= -46/9 (x greater than or equal to -46/9)
Step-by-step explanation:
when translating the question, at most means that it is less than or equal to the value being named, therefore the equation is 9x+21<= -25
to begin solving we subtract 21 from both sides and get 9x<=-46
then when we divide by 9 we have to flip the less than sign because we have to flip it if we multiply or divide.
This gives us the answer, x>=-46/9 which does not simplify any further

Step-by-step explanation:
because it would be the reciprical of 1/8 which is 8/1 plus 3
Step-by-step explanation:
Solve for a
k + a = v + w
a = v + w - k
Solution → { a = v + w - k }
<h2>
The required "option A) 20" is correct.</h2>
Step-by-step explanation:
Let x be the smaller than 4 ×
.
To find, the number of times smaller is 2 ×
than 4 ×
= ?
∴ x = 
= 2 ×
× 
Using the identity,

= 2 × 
Using the identity,

= 2 × 
= 2 × 10
= 20
Thus, the required "option A) 20" is correct.
