First you would distribute through the parenthesis
-10x+2+7(5x-1)-3(-5x+1)
Then distribute
-10x+2+35x-7-3(-5x+1)
And then distribute 3
-10x+2+35x-7+15x-3
Collect like terms
40x+2-7-3
40x-8 is your answer :)
<span>work out the difference (increase) between the two numbers you are comparing.Increase = New Number - Original Number.Then: divide the increase by the original number and multiply the answer by 100.% increase = Increase ÷ Original Number × 100.</span>
A = (n × s × a)2 A = ( n × s × a ) 2 , where n is the number of sides, s is the length of one side, and a is the apothe
Answer: Jack has $42
Step-by-step explanation:
Let be "j" the amount of money in dollars that Jack has, "w" the amount of money in dollars that Walker has and "t" the amount of money in dollars that Trust has.
You know that they have $100 altogether, then you can write the following equation:
[Equation 1]
Jack has $20 more than Walker, then:
[Equation 2]
And Trust has $14 more than walker, then you can write this equation:
[Equation 3]
Substitute the Equation 2 and the Equation 2 into the first one:

Now, solve fo "w":

Finally, substiute the value of "w" into the Equation 2 and evaluate:
