Answer:
Step-by-step explanation:
Solving (1):
Express as a unit ratio
This implies that, the second term must be 1. So, divide by 4
Solving (2):
Let the number be x.
x or equal to -3 means:
x or equal to 0 means:
So, we have:
and
Rewrite as:
and
Write together:
I believe this is J with a radius of 6
the formula for circumference is 2(pi)r so i just took the 12(pi) and divided it by 2, which left me with 6(pi), meaning that 6 would be the "r" in the situation
Answer:
No solution
Step-by-step explanation:
y = 2x + 4 (1)
-2x + y = -5 (2)
Rewrite equation (2)
y = 2x - 5
So now you have 2 equations
y = 2x + 4 (1)
y = 2x - 5 (2)
----------------------------------Subtract
0 = 9
As you know 0 is not equal 9
Answer: No solution
Answer:
$6400
Step-by-step explanation:
If Mrs. Hill takes out a mortgage for $80,000 with a 4% interest rate, what will her interest be after 20 years?
First you want to find how much she will get each year.
Turn 4% into a decimal.
Which you have to move the decimal point over to spaces to the left.
4. ----- .4 ----- .04
Now that you have done that you need to multiply,
$80000 × .04
which is $3200.
Now you know she gets $3200 a year.
Now multiply $3200 by 20.
$3200 × 20
which is $6400.
She will get $6400 interest.
Answer:
180cm^3
Step-by-step explanation:
4 times 5 = 20
20 times 9 = 180
cm^3 because it's 3d
