This is what I got as the answer, 2b x (12-17a)
Answer:
x × 0.1 < y × 0.2
x = 100, y = 10
Step-by-step explanation:
10% of a really large number can be bigger than 20% of a small number. 10% of 100 is 10. 20% of 10 is 2. 10 is bigger than 2 so Sergi's claim is false.
Answer:
x= 1/20
Step-by-step explanation:
-1/2x = -10
multiply by 2x on each side
2x(-1/2x) = -10*2x
-1 = -20x
divide by -20
-1/-20 = -20x/-20
1/20 =x
Answer:
-5
Step-by-step explanation:
-6 - 1(-1) involves multiplication as well as addition/subtraction. Order of operations rules require that we multiply before adding or subtracting, and so we have
-6 - 1(-1) = -6 + 1, which comes out to -5.
