Answer:
Step-by-step explanation:
27.4 = x - 47.8....add 47.8 to both sides, cancelling it on the left side
27.4 + 47.8 = x
75.2 = x <===
Answer:
a
Step-by-step explanation:
B . I say this because drops down and says the same 4-5 .
Step 1) turn 1.9 into an improper fraction.
= 19/10
step 2) find a least common denominator between 10 and 12.
= 60
(10x6 and 12x5)
step 3) convert the fractions so they have the same denominator.
= 19x6 is 114.
10x6= 60.
= 11x5 is 55.
12x5 is 60.
now you have your new fractions.
step 4) subtract.
= 114/60 - 55/60 is 59/60.
step 5) simplify.
the answer is either 0.9833... (3 repeating) or just 59/60 (you can't simplify the fraction any further).
Answer: -3.4.(-2) • (-2)= -48
Step-by-step explanation: please keep in mind that every number that you multiply by 0 is equal to 0, it does not mind if number is positive or negative the result will be always 0, if we have this clear we can pass with following step.
then you do not need resolve the equation with 0 because you know that result will be 0, after that we get only one equation the first one.
-3 * 4 * (-2) * (-2)
keep in mind when you are multiplying numbers with the same sign the product will be positive, but when you are multiplying numbers with different signs the result will be negative.
we can resolve this value by value for example
-3 * 4 * (-2) * (-2)
-3 * 4= -12
then we get the following equation
-12 * (-2) * (-2)
then we can pass with the next value
-12 * (-2) = 24
then we get the following equation
24 * (-2) = -48
as you can see this will be the only one equation with a negative product.
