-1 and 5

Step-by-step explanation:

<u><em>The correct question is</em></u>

Here are six number cards.

-4 -2 -1 5 6 8

Arrange the cards into three pairs with the same total.

step 1

Find the first pair

I take the numbers

-4 and 8

Adds the number to find out the total

-4+8=4

step 2

Find the second pair

I take the numbers

-2 and 6

Adds the number to find out the total

Remember that the total must be equal to the total of the first pair

-2+6=4 ---> is ok

step 3

Find the third pair

The remaining numbers are

-1 and 5

Check the sum

Remember that the total must be equal to 4

-1+5=4 ---> is ok

therefore

The three pairs are

-4 and 8

-2 and 6

-1 and 5

Parallel to y=2/3x+6 through (-3, 6)

Lana71 [14]

Answer:

y = (2/3)x + 8

Step-by-step explanation:

Parallel lines have the same slope. In the given equation, the slope is 2/3 so the slope of the parallel line will also be 2/3.

y = (2/3)x + ?

Plug in (-3, 6) for (x, y) in the equation.

6 = (2/3)(-3) + ?

6 = -2 + ?

? = 8

Final equation: y = (2/3)x + 8

Which expression is equivalent to (27.3-5.9)4?

makkiz [27]

Answer:

109.2-23.6 = 85.6

Step-by-step explanation:

use bodmas

B=bracket

O=of or multiplication

D=division

M=multiplication

A=addition

S=subtraction

so when you are opening a bracket you multipli the number in the bracket with the one outside the bracket

I.E

4×27.3=109.3

Write data in increasing order.

3, 5, 5, 6, 6, 6, 7, 7, 8, 8, 8, 8, 8, 8, 9, 9, 10, 10, 10, 10, 11

Find the median

Median is 8

Lower half of the data is : 3, 5, 5, 6, 6, 6, 7, 7, 8, 8,

First quartile is the median of the lower half of the data=6+6 /2 =6

Upper half of the data is: 8, 8, 8, 9, 9, 10, 10, 10, 10, 11

The Third quartile is the median of the upper half=9+10 / 2 = 9.5

Simplify the expression –2(p 4)2 – 3 5p. what is the simplified expression in standard form? –2p2 – 11p – 35 2p2 21p 29 –2p2 13p

Aleksandr-060686 [28]

The simplified expression of the provided equation in standard form is -2p²-11p-35. Option 1 is the correct option.

<h3>What is the simplified form of an expression?</h3>

Simplified form of an expression is the simplest way of expression the term, by applying the required operations of mathematics.

The expression which is need to be simplified is,

$-2(p +4)^2 - 3 +5p$

First of all, open the brackets, using the formula of whole square,

$-2(p^2 +16+8p) - 3 +5p\\-2p^2-32-16p-3+5p\\-2p^2-11p-35$

Hence, the simplified expression of the provided equation in standard form is -2p²-11p-35. Option 1 is the correct option.
