How to write two different pairs of decimals whose sums are 14.1. One pair should involve regrouping

Mathematics
1 answer:
Nitella [24]3 years ago

To solve, first let’s define regrouping:<span>
<span>=> Regrouping involves carrying and borrowing during subtraction and addition of the given numbers.

So let us have the non-regrouping decimal number: 
=> 8.4
Next, the other regrouping decimal 
=> 5.7

So now let us show how it becomes 14.1:
  8.4
+5.7
14.1

Starting from the right, 4 + 7 is equal 11, so bring down 1 and carry 1. Now 8+5 = 13, but 13 + carry 1 = 14
<span>Thus, the answer is 14.1</span></span></span>

Given the statement “if there is a lightning storm then we won’t go swimming”, which is contapositive?
8090 [49]

The contrapositive statement is "If we go swimming, then there is no lightning storm"

<h3>What is a contra positive statement?</h3>

A contrapositive statement is a proposition or theorem formed by contradicting both the subject and predicate or both the conclusion and hypothesis of a given proposition or theorem and interchanging them.

Example : "if not-B then not-A " is the contra positive of "if A then B "

Given the statement;

“if there is a lightning storm then we won’t go swimming”

The contra positive statement is;

"If we go swimming, then there is no lightning storm"

Thus, the contrapositive statement is "If we go swimming, then there is no lightning storm"

(HELP!! WILL GIVE 86 POINTS!!)
astraxan [27]

Answer: 2(−x+y=−2)

2(−x+y=−2)

1(2x−3y=4)

Becomes:

−2x+2y=−4

2x−3y=4

Add these equations to eliminate x:

−y=0

Then solve−y=0for y:

−y=0

−y/-1 = 0/-1 (Divide both sides by -1)

y=0

Step-by-step explanation:

Now that we've found y let's plug it back in to solve for x.

Write down an original equation:

−x+y=−2

Substitute 0 for y in −x+y=−2:

−x+0=−2

−x=−2(Simplify both sides of the equation)

−x/-1 = -2/-2 (Divide both sides by -1)

x=2

Answer:

x=2 and y=0
