Answer:
7x+3
Step-by-step explanation:
To simpfly, it would help by simply ignoring the variable (x) and just looking at the number before it, solving it like a regular math problem, from left to right.
9(x) - 2(x) = 7(x)
(-4)-(-7) = 3 --> since there's a minus sign in the middle subtracting the two numbers and one on the -7, the -7 becomes a positive 7. A negative times a negative is always positive so, it would technically be -4+7=3.
Put both of these two numbers together and you get your answer,
7x+3.
If you're having trouble with the part I explained the image might help. Read it from left to right. A negative # + a negative # = positive #, as seen by the first row.
Hey there! :)
Answer:
$3600.
Step-by-step explanation:
If the wife received $6000 which is a quarter of the money, solve for the total amount of the fortune:
1/4x = 6000
Multiply both sides by 4:
x = $24000
We can begin by subtracting the wife's amount from the total:
24000 - 6000 = $18000
He has 3 sons and 4 daughters. Let 'x' represent the amount the daughters received, and '2x' the amount the sons received.
18000 = 3(2x) + 4(x)
Distribute and combine the terms:
18000 = 6x + 4x
18000 = 10x
Divide both sides by 10:
18000/10 = 10x/10
x = $1800. This is the amount that each daughter receives. Since the sons receive '2x':
2(1800) = $3600.
Answer:
x = 17.2
Step-by-step explanation:
cos 35 = x/21
0.8192(21) = x
x = 17.2
The steepness of the slope for directly proportional relationships increases as the value of the constant m (y = mx) increases. In our two speed examples, the change in steepness of slope represents the change in speed or the change in the unit rate.
