There are about 2.2 pounds in one kilogram. If Allison's bag weighs
19.54 pounds, about how many kilograms does it weigh? Did you multiply
or divide to find your answer?
a. 8.88, divide c. 8.88, multiply
b. 39.08, multiply d. 39.08, divide

Hello,

[tex]( {c}^{2} + {d}^{2} ) - 2( {c}^{2} - {d}^{2} )[/tex]

[tex] = (( - 2) {}^{2} + 2 {}^{2} ) - 2(( - 2) {}^{2} - 2 {}^{2} )[/tex]

[tex] = (4 + 4) - 2(4 - 4)[/tex]

[tex] = 8 - 2 \times 0[/tex]

[tex] = 8[/tex]

Answer: is five over 8

Step-by-step explanation:

Answer: 8 over 5 :p

Step-by-step explanation:

Answer: D

Step-by-step explanation:

Follow the PEMDAS rule.
It’s not A, because when you solve 2^2 and sq rt of 4, the square exponent and the square root cancels out, so it’s simply 2 x 4. Then you follow by doing division and multiplication, 45/5 is 9 and 2 x 4 is 8, so 9+8=17.

It’s not B, because first solve the numbers in the parentheses. 2^2 is 4, 5+4 is 9. Then solve the square root of 4 which is 2, and you get 45/9x2, which is 10.

It’s not C because 2^2 is 4 and sq rt of 4 is 2, and 4-2 is 2. Then divide 45 by 5 to get 9, and 9+2 is 11.

The correct answer is D, because when you solve 2^2 which gives you 4 and add that to 5, you get 9. The sq rt of 4 is 2, so you get 45/9-2, which is 3.

Hope this helps!

Q6. -5/2

Q7. -7/24

Q8.  127/24

Q9. 151/12

Step-by-step explanation:

Q6. (−3/4)+(−7/4) = -3-7/4 = -10/4 = -5/2

Q7. 3/8 - 2/3 = 3*3/8*3 - 2*8/3*8 = 9/24 - 16/24 = 9-16/24 = -7/24

Q8. 18+2/3 - 8+3/8 = 20/3 - 11/8 = 20*8/3*8 - 11*3/8*3 = 160-33/24 = 127/24

Q9. 12+1/4 + 27+1/3 = 13/4 + 28/3 = 13*3/12 + 28*4/12 = 39 + 112/12 = 151/12

Step-by-step explanation:

The perimeter of the rectangle is given as:

The perimeter of a rectangle is:

So, we have:

Substitute values for length and width

Split

or

or

Divide both sides by 2

or

Solve for x

or

or

Both values of x are negative.

This means that; the absolute value model cannot work, because a rectangle cannot have a negative dimension.

Hence, option (c) is correct.

Answer: -342.7074

Step-by-step explanation: first multiply 7(-2.655), which is -18.585. since only one of the numbers is negative, the product will also be negative. multiply -18.585 by 18.44. this is equivalent to -342.7074.

Answer: -$843

Step-by-step explanation:

843 x 3 = $2529    

843 x 2 = $1686

2529 - 1686 = $843

The zoo makes $2529 on a regular night, but because there is a discount, they make $1686. The amount of money is the difference between the two totals. Therefore, the total amount of money the zoo lost by reducing the price is $843.

Answer: v=-5/8

Step-by-step explanation:

v - 1/2 = -9/8

(v - 1/2 = -9/8)*8      ==> multiply the equation by 8 to get rid of fractions

8v - 8*1/2 = -9

8v-8/2=-9

8v-4=-9

8v=-5

v=-5/8

Answer: v=-5/8

Answer:

19.28 kilometers

Step-by-step explanation:

40 percent *48.2

= (40/100)*48.2

= (40*48.2)/100

= 1928/100 = 19.28

Now we have: 40 percent of 48.2 = 19.28

Question: What is 40 percent of 48.2?

We need to determine 40% of 48.2 now and the procedure explaining it as such

Step 1: In the given case Output Value is 48.2.

Step 2: Let us consider the unknown value as x.

Step 3: Consider the output value of 48.2 = 100%.

Step 4: In the Same way, x = 40%.

Step 5: On dividing the pair of simple equations we got the equation as under

48.2 = 100% (1).

x = 40% (2).

(48.2%)/(x%) = 100/40

Step 6: Reciprocal of both the sides results in the following equation

x%/48.2% = 40/100

Step 7: Simplifying the above obtained equation further will tell what is 40% of 48.2

x = 19.28%

Therefore, 40% of 48.2 is 19.28

Answer: - 1.28
