Answer:
-3.0625
Step-by-step explanation:
just plug in -12
3/4t-3
3/2(-12)-13
then solve to get -3.0625 or -3.06
and this is how you solve any problem like this.
534 is the product of 6x89
Part A:
Circumference = πd
Circle A: d = 7
7π = 21.98
π = 21.98/7 = 3.14
Circle B: d = 6
6π = 18.84
π = 3.14
Part B:
Area = πr^2
Circle A: r = 3.5
π3.5^2 = 38.465
12.25π = 38.465
π = 3.14
Circle B: r = 3
π3^2 = 28.26
9π = 28.26
π = 3.14
Part C: The value of π is the same in circles A and B
Answer:
option 1 and 4
Step-by-step explanation:
The elimination method should be used when there are two variables with the same number in front of them but different signs.
In the first system, the first equation has -8y while the second one has 8y.
Both equations have an 8y with different signs therefore using the elimination method would be most logical.
In the fourth system, the first equation has a -4x while the second one has 4x.
Both equations have 4x with different signs therefore using the elimination method would be most logical
Reasons it can't be the other options :
In the second system, no variable has the same number before it so no variable can be eliminated unless you multiply the equations by a common multiple. The best method for this system would be graphing
In the third system y is defined by an expression therefore using the substitution method is the most logical approach.
