Help pls i cant answer and i need to get them right
1 answer:
The expression has 2 factors, and the second factor has 2 terms.
<h3 /><h3>How many factors has the expression?</h3>We can write an expression of N factors as:
Here, the expression is:
4*(8x + 5)
This expression has 2 factors, which are:
4 and (8x + 5)
Now, if we look at the only factor 8x + 5, we have two terms (the terms are the parts that are added), the terms are:
8x and 5.

30 pounds of raspberries and 50 pounds of blueberries are sold
<em><u>Solution:</u></em>
Let "a" be the pounds of raspberries sold
Let "b" be the pounds of blueberries sold
Cost per pound of raspberry = $ 1
Cost per pound of blue berry = $ 3.25
<em><u>Maya made $192.50 from selling a total of 80 pounds of raspberries and blueberries</u></em>
Therefore,
a + b = 80
a = 80 - b ------- eqn 1
<em><u>Maya made $192.50. Therefore, frame a equation as:</u></em>
pounds of raspberries sold x Cost per pound of raspberry + pounds of blueberries sold x Cost per pound of blue berry = 192.50
a + 3.25b = 192.50 ------ eqn 2
<em><u>Let us solve eqn 1 and eqn 2</u></em>
<em><u>Substitute eqn 1 in eqn 2</u></em>
80 - b + 3.25b = 192.50
2.25b = 192.50 - 80
2.25b = 112.5
Divide both sides by 2.25
b = 50
<em><u>Substitute b = 50 in eqn 1</u></em>
a = 80 - 50
a = 30
Thus 30 pounds of raspberries and 50 pounds of blueberries are sold
