Answer:
Not true
Step-by-step explanation:
x + (2x + 5) = 3(x – 4)+7
Opening bracket on left and side and distributing 3 over (x-4) on right hand side
x+2x+5=3x-3 x 4 + 7
adding like terms
3x+5=3x-12+7
3x+5=3x-5
Hence
5 = -5
Which is not possible , Hence the equation given to us is false.
Answer:
If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. If they are inversely proportional, an increase in the value of one variable would cause a corresponding decrease in the other variable.
Looking at the given values, as x is increasing, y is also increasing. The constant of proportionality is
9/3 = 27/9 = 3
Therefore, the relationship is a direct variation and the function to model it is
y = 3x

Answer:
-20
Step-by-step explanation:
6(-3) - |-5| + |3|
First multiply
-18 - |-5| + |3|
Then take the absolute values
-18 - 5 + 3
Subtract
-23 +3
Add
-20
Hey there, 125/5=25 and 25*5=125, Therefore, ∛125=5
Answer:
66 tens - 38 tens= 58 tens
Step-by-step explanation:
You will start off by making the 6 in the ones place a 16 since you can't subtract 6-8 and change the 6 in the tens to a 5 since you borrowed. Hope this helps! :)
