Answer:
Cost of each individual book = $10.5
Step-by-step explanation:
Given:
Cost of 3 book set = $24.81
Amount save = $6.69
Find:
Cost of each individual book
Computation:
Assume:
Cost of each individual book = a
Total cost = 3a
So,
Total cost = $24.81 + $6.69
Total cost = $31.5
So,
3a = $31.5
a = $10.5
Cost of each individual book = $10.5
Step-by-step explanation:
Work out 32 as a product of prime factors in index form
First find out the factor for 32
32 can be break into 16 times 2
16 can be break into 8 times 2
8 can be break into 4 times 2
4 can be break into 2 times 2
So, 32 can be written as
Answer:
The index form of the 32 is
Gaira made a mistake when substituting the value –7.5 in for x.
She multiplied both terms of the expression by –7.5 when she should have only multiplied –3.8 by –7.5.
The value of the expression is 34.5.
Given
Gaira was asked to evaluate the algebraic;
–3.8x + 6 when x = –7.5.
<h3>What is an algebraic expression?</h3>
Algebraic expressions consist of numbers and variables along with operational signs.
Gaira made a mistake when substituting the value –7.5 in for x.
She multiplied both terms of the expression by –7.5 when she should have only multiplied –3.8 by –7.5.
To solve the following expression follow all the steps given below.
Then,
The correct expression is;
Hence, the value of the expression is 34.5.
