Step-by-step explanation:
I think you meant 3([7/5]x + 4) - 2(3/2 - [5/4]x). If that's the case, then identify the LCD: It is 20. Multiply both [7/5]x + 4 and 3/2 - [5/4]x by 20 and then divide the resulting expression by 20:
3(28x + 80) - 2(30 - 25x)
------------------------------------
20
Next, perform the indicated multiplication:
84x + 240 - 60 + 50x
----------------------------------
20
This simplifies to:
34x + 180 17x + 9
---------------- = ----------------
20 10
Next time, please share the answer choices.
2x+y=-4
5x+3y=-6
multiply first equaton by -5 and second by 2 then add them
-10x-5y=20
<u>10x+6y=-12 +</u>
0x+1y=8
y=8
the y value is 8
How to solve the equation Multiply the cost of an item or service by the sales tax in order to find out the total cost. The equation looks like this: Item or service cost x sales tax (in decimal form) = total sales tax. Add the total sales tax to the Item or service cost to get your total cost.

Answer:
If each of three people are given three-tenth of an apple shared, what fraction of the apple was received by the three people?
9/10
Explanation:
The given multiplication is 3 x 3/10
The word problem that can result to the mathematical expression 3 x 3/10 is:
<em>If each of three people are given three-tenth of an apple shared, what fraction of the apple was received by the three people?</em>
Since each of the people get 3/10 of the apple
The three people received a total share of 3 x 3/10 = 9/10r
