Its either D or A go with ur gut I think u got it right :)
Answer:
n=3
Step-by-step explanation:
-5 (6n +8) =50
First distribute the -5 to 6n and 8. Remember to multiply with the sign!
so -5 x 6n and -5 x 8
which = -30n and -40
so our new equation is
-30n - 40=50
we add 40 to the other side since we want the answer of the variable
-30n - 40 +40 = 50+40
-30n =90
we divide -30 from n to get n alone.
-30n/-30 = 90/-30
n=-3
We can check our answer by plugging it into the equation.
50= -5 (6(-3) +8)
50 = -5 (-18+8) -> 50= -5 (-10)=50
7 1/4 + 5 3/5
First, you need a common denominator to add the two. 20 will work.
4x5=20, so we have to also multiply 1 by 5.
4x5=20, 1x5=5
5x4=20, so we have to also multiply 3 by 4.
5x4=20, 3x4=12
And now we put the fractions back in.
7 5/20 + 5 12/20
And add them.
7 5/20 + 5 12/20 = 12 17/20
Now, we're supposed to reduce it to its lowest form.
Unfortunately, the fraction cannot be reduced, because 17 is a prime number, meaning there are no factors to it except one and itself.
Therefore, the lowest form of 12 17/20 is 12 17/20
Your answer is B, 12 17/20
Answer:
The fill in the blank answer is Formula.
Step-by-step explanation:
In Calc, a mathematical equation is called a - Formula.
A formula can also be defined as some rule that can be expressed in symbols also. The formulas derive some mathematical relationship also.
