Answer:
-23
Step-by-step explanation: You have to combine like terms first:
-3.8x -5.9x =223.1
-9.7x = 223.1
Then divide om each side of the equation by -9.7.
-9.7x/-9.7 = 223.1/-9.7
x =- 23
x=-23
Step-by-step explanation:
-<u>3.8x</u>-<u>5.9x</u>=223.1
Collect like terms by calculating the sum or difference of their coefficients
(-3.8-5.9)x
calculate the difference
-<u>9.7x</u>=223.1
Divide both sides of the equation by -9.7
-9.7x÷(<u>-9.7</u>)=223.1÷(<u>-9.7</u>)
Any expression divided by itself equals 1
x=223.1÷(-9.7)
1 + 2i and 1 – 2i
B) {56, 66, 95, 90, 57, 66, 69, 68, 76, 64, 51}
{56, 66, 95, 90, 57, 66, 69, 68, 76, 64, 51} is the only data set that matches the maximum and minimum, upper and lower quartile, and median values.
a, b, c, and e.
