Answer:
x = 2
Step-by-step explanation:
3x + 1 = 7
3x = 7 – 1
3x = 6
x = 6/3
x = 2
Answer:
a) b ≈ 100
b) m ≈ 30
Step-by-step explanation:
Answer:
3x = 3 + 2y -------------> 3x - 2y = 3 {subtracted 2y from each side of top equation}
(-4/3)x + y = -2/3 ------> -4x + 3y = -2 {multiplied bottom equation by 3}
3x - 2y = 3 ------> 12x - 8y = 12 {multiplied top equation by 4}
-4x + 3y = -2-----> -12x + 9y = -6 {multiplied bottom equation by 3}
12x - 8y = 12
-12x + 9y = -6
--------------
y = 6 {added the two equations}
3x = 3 + 2y {original top equation}
3x = 3 + 2(6) {substituted 6, in for y, into top equation}
3x = 3 + 12 {multiplied}
3x = 15 {added}
x = 5 {divided each side by 3}
x = 5 and y = 6
Step-by-step explanation:
Circumference is 56.54866776 and Area is 254.4690049
Answer: A.)The response variable is the amount of activity the patients were able to do after surgery, and the explanatory variable is the type of spinal surgery.
Step-by-step explanation:
The response variable focuses on the question in a study or an experiment while the explanatory variable is the one which explains the changes in that variable.
Here response variable is the amount of activity the patients were able to do after surgery while the explanatory variable will be spinal surgery type
Option A is correct
