Which product is negative? −6⋅(−7)⋅(−8)⋅0 −3⋅(−2)⋅(−4)⋅(−7) −2⋅(−7)⋅12⋅(4) 4⋅(−9)⋅(−3)⋅(−1)
Answer:
Last choice
Step-by-step explanation:
To say it simply if products are in negative or not, we can tell by:-
Looking at negative symbolsThen count how many negative signs are there.If there are even-number signs (2 negative signs, 4 negative signs, etc.) then the product is positive.If there are odd-number negative signs (a negative sign, 3 negative signs, 5 negative signs, etc.) then the product is negative.The only choice that has odd-number negative signs is last choice — othere have 2 or 4 negative signs.
Additionally, keep in mind that:-
positive • positive = positivepositive • negative = negativenegative • negative = positivesame signs multiply each others = same signopposite signs multiply each others = negative (For plus and minus)Above are important fundamental to Algebra and many mathematic courses so you better remember it!

Write what you did and why you did it.
Answer:
$74
Step-by-step explanation:
Let amount of money that K has be $x.
x+x+11+2x=159
4x+11=159
4x=159-11
=148
x=148÷4

A car traveled 63 miles on 3 gallons of gas. What proportion can you set up to determine how many miles m the car can travel on 7 gallons of gas?
The Answer is 147 miles.
Answer:
The car can travel 147 miles on 7 gallons of gas
Step-by-step explanation:
A car traveled on 3 gallons of gas = 63 miles
car traveled on 1 gallons of gas = = 21 miles
Therefore, car traveled on 7 gallons of gas = 21 × 7 = 147 miles.
The proportion will be = × 7 = × 7
The car can travel 147 miles on 7 gallons of gas.

Conversion a mixed number 2 2/5 to a improper fraction:-
=> 2 2/5 = 2 × 5 + 2 = 12/5
To find new numerator:
a) Multiply the whole number 2 by the denominator 5. Whole number 2 equally 2 * 5/5
= 10/5
b) Add the answer from previous step 10 to the numerator 2. New numerator is 10 + 2 = 12
c) Write a previous answer (new numerator 12) over the denominator 5.
Two and two fifths is twelve fifth
Multiple:
= 12/5 × 5/7
= 12 × 5/5 × 7
= 60/35
= 12 × 5/7 × 5
= 12/7
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(60, 35) = 5. In the next intermediate step, , cancel by a common factor of 5 gives 12/7
12/7 in mixed fraction is 1 5/7

Which statement about the solving process when an equation has no solution or infinite solutions is TRUE?
The variable will always end up on the left-hand side of the equation.
The constant terms will always be a multiple of 3.
Collecting the like terms will result in the elimination of the variable.
Gathering the like constant terms will always result in the value 0.
Answer:
A
Step-by-step explanation:
The variable will always end up on the left-hand side of the equation
The statement that is true about the solving process when an equation has no solution or infinite solutions is: “The variable will always end up on the left-hand side of the equation.” Hence, Option A is correct.
What are infinite solutions?Both sides are equivalent in an endless solution. For instance, 12x + 4y - 16 = 6x + 2y - 8 Using a formula or method for infinite solutions, one can simplify the equation and make both sides equal to one another, making it an infinite solution. Infinity is a symbol for boundlessness or infinity. The sign "∞" is typically used to denote it.
When the lines are parallel and they share the same y-intercept, the system of equations has an infinite number of solutions. If the slope and y-intercept of two lines match, they are in fact the exact same line. The variable, which always appears on the left side of the equation, has infinite solutions.
Therefore, Option A is correct.
