Answer:
m=-3
Step-by-step explanation:
m-10=-13
m=-13+10
m=-3
Answer:
m = -3
Step-by-step explanation:
Translate into an expression a part of the expression at a time.
ten less than m is -13
m - 10
ten less than m is -13
m - 10 = -13
Add 10 to both sides.
m = -3
Answer:
Any equation of a line having a slope of 1/2.
Step-by-step explanation:
It appears that the question gives answer choices and this problem could have many solutions, but parallel lines have equal slopes. The slope of this line is 1/2 since it is in y=mx+b form where m is the slope. So a few examples of equations of lines parallel to the given equation would be y = 1/2x - 5 or y = 1/2x + 10 etc.
It's a factor. This concept is widely used throughout algebra, and you'll probably bump into it through the end of high school and beyond.
A common use is expressing a term in prime factorization, or reducing a number to its most base parts- primes. For example:
Of course, a number like 13 which is already prime is made up of itself and 1. Factors do not have to be primes. 20 is also reducible through combinations of 1, 2, 4, 5, 10, and 20. Prime factorization is just a handy example.
Basically, factors multiply with each other to create other numbers, and numbers can be reduced down to their factors.
Answer:
2.25
Step-by-step explanation:
x^2 + 3x =6
Take the coefficient of the x term
3
Divide by 2
3/2 = 1.5
Square it
1.5^2 =2.25
Add this to both sides of the equation
Answer:
3/2^2
Step-by-step explanation:
Answer:
t + 3:45 = 11:20 am
Step-by-step explanation:
A rocket is scheduled to launch from a command center in 3.75 hours.
The launch time is 11:20 am.
We need to know the time before 3.75 hours of 11:20 am.
3.75 hours = 3 hours (0.75 × 60) = 45 minutes
Let the current time be 't'
Now the equation will be
t + 3:45 = 11:20 am
t = 11:20 - 3:45
t = 7 : 35 am
Before 3.75 hours of 11:20 am it will be 7:35 am.
The equation would be 3.75+t=11.2 so:
3.75+t=11.2
3.75+t-3.75=11.2-3.75
t=7.45, which is 7:35.
