A , sorry i just needed the point to ask questions
Answer:
The correct answer is d. (40, 60)
Step-by-step explanation:
To start using the linear combination method, you need a variable that will cancel out. To get this, we will multiply the second equation by -20 and then add together.
x + y = 100
-1.4x - y = -116
-----------------
-0.4x = -16
x = 40
Now that we have the value of x, we plug into one of the original equations to find y.
x + y = 100
40 + y = 100
y = 60

"<span>Evaluate z + z + z for x = 2, y = -3, z = -4."...
Input the information given:
(-4)+(-4)+(-4)
=-8+(-4)
=-12
The answer to the expression would be -12.
Hope this helps.

Question 1 = 14 & -14
question 3= 15 & -15
question 5 = 13 & -13
Answer:
2*2*3*5
Step-by-step explanation:
Use a factor tree to express 60 as a product of prime factors. So the prime factorization of 60 is 2 × 2 × 3 × 5, which can be written as 2 2 × 3 × 5. The actual prime factors of 60 are 2, 3, and 5.
