Translate the statements to algebraic expression
Represent the power with x;
So, the left hand side is
<em>Power of 10: </em>
<em />
<em>Times n: </em>
<em />
<em />
The right hand side is:
<em>0.1515 * power of 10: </em>
<em />
Equate the right hand side to the left:


Hence;
<em>The required expression is </em>

Answer:
strawberry=7/8
Step-by-step explanation:
treat strawberry as x
add on proportions
1 1/8+ 3/4+ 1 3/4 + x = 4 1/2
(9+6+14)/8 + x = 9/2
29/8 +x = 9/2
x= 9/2 - 29/8
x= (36-29)/8
x=7/8
