Answers

Answer 1

Answer: 1. multiply to -18 add to -17 = Multiplying -18 and 1 will give -18 as the result and then on adding -18 and + 1 the result comes to -17
2. multiply to 36 add to -13 = Multiplying -9 and -4 will give -36 as the result and then on adding -9 and -4 the result comes to -13
3. multiply to -24 add to -5= Multiplying -8 and +3 will give -24 as the result and then on adding -8 and +3 the result comes to -5
4. multiply to -18 add to 7= Multiplying +9 and -2 will give -18 as the result and then on adding +9 and -2 the result comes to 7
5. multiply to -36 add to 9= Multiplying +12 and -3 will give -36 as the result and then on adding +12 and -3 the result comes to 9
6. multiply to 24 add to 10= Multiplying +6 and +4 will give 24 as the result and then on adding +6 and +4 the result comes to 10
7. multiply to 18 add to -9= Multiplying -6 and -3 will give -18 as the result and then on adding -6 and -3 the result comes to -9
8. multiply to -36 add to -16= Multiplying -18 and +2 will give -36 as the result and then on adding -18 and +2 the result comes to -16

The table can be used to determine the solution of equations, 2x − 2y = 6 and 4x + 4y = 28.A table with 6 columns and 2 rows. The first column, Original System has 2 x minus 2 y equals 6 and 4 x plus 4 y equals 28. The second column, Equivalent System, has 4 x minus 4 y equals 12 and 4 x plus 4 y equals 28. The third column, Sum of equations in Equivalent System, has 8 x equals 40. The fourth column, Solution to System, is blank. The fifth column, New System Using Sum, has 4 x plus 4 y equals 28 and 8 x equals 40. The sixth column, Solution to New System is blank.

Answer:

$(5,2)$

Step-by-step explanation:

$2x-2y=6\n4x+4y=28$

Column 1 :

$2x-2y=6..........(1)\n4x+4y=28........(2)$

Column 2 :

Eqn(1) $*\ 2$

$4x-4y=12\n4x+4y=28$

Column 3 :

Add the equations.

$(4x+4x)-4y+4y=12+28\n8x=40$

Fourth column :

$8x=40\nx=(40)/(8)=5$

Fift column :

$4x+4y=28\n8x=40$

Sixth column :

Substitute $x=5$ .

$4* 5+4y=28\n4y=28-20\n4y=8\ny=2$

Hence solution is $(5,2)$ .

Ben needs to buy orange juice. He can buy 64 fl oz at the grocery store for $2.00, or he can buy 256 fl oz at the wholesale club for $7.50| a) Find the unit price for the grocery store orange juice. Round your answer to the nearest thousandth.| b) Find the unit price of the wholesale club orange juice. Round your answer to the nearest thousandth.| c) Where should ben buy orange juice ifhe wants the best deal? Explain.

Answers

2. unit price = $ ÷ oz
a) 64 fl oz for $2 = 2/64 ≈ $0.031 per ounce
b) 256 fl oz for $7.5 = 7.5/256 = $0.029 per ounce
c) buy wholesale because 0.029 < 0.031

3. unit rate means 1 for the miles
3/10 in ÷ 7/8 mi
= 12/35 inches per mile ...

Write a whole number and a fraction greater than q to name the part filled. think: 1 carton = 1

Answers

q=4 wholes because it would be 12/3 and u reduce it by 3/3 and you get 4/1 and that's a improper fraction so it will be 4 wholes

A square painting has a diagonal of 44 in. Lorraine wants to frame the picture. How many inches of frame will she need? Round to the nearest inch.

Answers

The square has a diagonal of 44 inches.
In order to get the side, we need to use the pythagorean equation.

Diagonal (d) ^ 2 = side^2 + side ^ 2
Diagonal (d) ^ 2 = 2side (s)^2

d^2 = 2s^2
44^2 = 2s^2
1936 = 2s^2
2s^2 = 1936
s^2 = 968
s = 31.11 inches

The length of the side is approximately 31 inches.
Perimeter = 4*s
Perimeter = 4 * 31
Perimeter = 124 inches

So she need a total of 124 inches to frame the square.

I am sure the anwser is 124in

I hope this helps let me know! ;)
