X=3
Steps:
I used a calculator.
For a system of equations such as this, add both of the equations together. The d values will cancel each other out, making 2e=-4. This means that e=-2. If you plug this into one of the equations, you will have d + (-2) = 1. Isolate the variable by adding -2 to both sides: d=3. Written in the format described above (d,e), your answer is (3, -2).
Answer:
A. 24
Step-by-step explanation:
1. 4 x 5 then 2. 18/3 then 3. - 2
X+8+3x+2=180
4x+10=180
Subtract 10 from both sides
4x=170
X=45.5

Answer:
370
Step-by-step explanation:
The set B∩(F∪M) is the sum of the numbers on line B in both the M and F columns:
B∩(F∪M) = 54 +316 = 370
The set B∩(F∪M) contains 370 respondents.
