Here are six number cards -4,-2,-1,5,6,8
arrange the cards into three pairs with the same total
Answers
Answer:
5 and 6 and -1
6 and 8 and -4
5 and 8 and -2 and -1
Step-by-step explanation:
They all add up to 10.
The trick is to first figure out if you can combine 5 6 or 8 together, then use the negative numbers to subtract as needed to reach you number. If you add 5 and 6, that is 11, but -1 can make 10. When you add 8 and 6, that is 14. But good thing you have the -4 to make 10. You start with the smallest number found from adding together two numbers from the positive pile like 5 and 6.
You can make other combinations as well. 11 could work too.
please click heart to give thanks :) c
The pairs of cards are (-4, 8), (-1, 5) and (-2, 6) respectively.
What is addition?Addition is a mathematical operation which used to count the things when are together. The addition of two positive integers are greater than both of them while for negative integers it is less than both of them.
Given that,
The different cards having numbers on them are as below,
-4, -2, -1, 5, 6, 8.
In order to select them into three pairs having the same sum make the pair as follows,
Add each positive number to each of the negative numbers and then select the pair of numbers having the same sum.
Thus, it is obtained as,
-4 + 8 = 4
-1 + 5 = 4
-2 + 6 = 4
Hence, the required pairs of cards are (-4, 8), (-1, 5) and (-2, 6) respectively.

Answers
Answer:
The answer is false and is not
Explanation:
Given the equation - [tex]4x+12=4[/tex]
Substitute x = 2 in the equation
[tex]4(2)+12=4\\8+12=4\\20=4[/tex]
Thus, the equation is false. When the equation is false, meaning that the coordinate x-term isn't passed by the line. (Rather say that the point is not the part of the graph.)
The equation is false is our first answer.
If the equation is false, that means the given value is not part of the graph, thus making the x-value not the solution.
Answer:
The equation is FALSE when x=2, so 2 IS NOT a solution.

Answer:
D. 1/3^3
Step-by-step explanation:
Divide 3/3 as usual and get 1.
When dividing exponents, you are actually subtracting them. 5-8 = -3.
D is the answer because positive exponents in the denominator of the fraction is the same as a negative exponent in the numerator.
The rule with exponents is that when dividing similar bases with different exponents (or power), you subtract the exponents respectively.
3⁵ / 3⁸ = 3⁽⁵ ⁻ ⁸⁾ = 3⁻ ³ = 1 / 3³
So the answer is
D) 1/3³

In the year 2009, a company made $8.4 million in profit. For each consecutive year
after that, their profit increased by 14%. How much would the company's profit be in
the year 2011, to the nearest tenth of a million dollars?
Answers
Answer:
$10.8 million or 10,752,000
Step-by-step explanation:
14% of 8,400,000 is 1,176,000
t = time in years
In one year, the company would make 8,400,000+(t*1,176,000)
In 2 years they make 8,400,000+(2*1,176,000) = 10,752,000
now round 10,752,000 to the nearest hundred thousand, which is 1/10 of 1,000,000.

Diego compro un libro y tres cuadernos,pago por ellos 180 solo recuerda que el libre le costó el doble de lo que le costaron los tres cuadernos juntos
Answers
Answer: Cada cuaderno cuesta 20, y el libro 120.
Step-by-step explanation:
Vamos a definir:
L = precio de un libro
C = precio de un cuaderno.
Sabemos que Diego compro un libro y tres cuadernos por 180, entonces tenemos:
1*L + 3*C = 180
También sabemos que el libro costo el doble de lo que costaron los 3 cuadernos juntos, entonces:
L = 2*(3*C) = 6*C
Tenemos un sistema de ecuaciones:
1*L + 3*C = 180
L = 6*C
Para resolverlo, podemos reemplazar la segunda ecuación en la primera, para así obtener:
1*(6*C) + 3*C = 180
6*C + 3*C = 180
9*C = 180
C = 180/9 = 20
Cada cuaderno costo 20.
Y el precio del libro se puede obtener con la ecuación:
L = 6*C = 6*20 = 120
El libro costo 120

Answer:
The composite area is a total of 62 square inches.
Step-by-step explanation:
You're given three rectangles of different width and height. To find the correct answer, you need to find the sum of each rectangles' area.
first though we need to find the height of the middle rectangle. We are told the total height and the other two rectangles' heights, so we just need to subtract the others' heights from the total:
10 - (4 + 1.5)
10 - 5.5
= 4.5
So the middle rectangle is 4x4.5 inches, giving it an area of 18 square inches
The top one is 8x4 inches for a total of 32 square inches.
And the bottom one is 1.5x8 inches, for a total 12 square inches.
If we add them all up, that's 18 + 32 + 12 square inches, or 62 square inches.
