Answer:
Below.
Step-by-step explanation:
-5/8 * 1/3 = -5/24
-5/12 * 1/2 = -5/24
-5/6 * 1/4 = -5/24.
Answer:
$233.92
Step-by-step explanation:
First things first, you can begin this problem by adding $138.52 + $75.00. When you do that, you get 213.50. Next, you multiply $6.80(3), and when you do that get $20.40. The Final step is that you add $213.50 +$20.40 to get $233.92.
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;
![=-3.8x + 6\\\\\text{Substitute the value of x = -7.5}\\\\= -3.8(-7.5)+6\\\\= 28.5+6\\\\=34.5](https://tex.z-dn.net/?f=%3D-3.8x%20%2B%206%5C%5C%5C%5C%5Ctext%7BSubstitute%20the%20value%20of%20x%20%3D%20-7.5%7D%5C%5C%5C%5C%3D%20-3.8%28-7.5%29%2B6%5C%5C%5C%5C%3D%2028.5%2B6%5C%5C%5C%5C%3D34.5)
Hence, the value of the expression is 34.5.
