well -2(-1/4) is .5
so -2, .5,(multiply each by -1/4)
-2, 0.5, -0.125, 0.03125
Answer:
$0.45.
Step-by-step explanation:
Total amount of money held by all 5 children
= 5 * 0.50 = $2.50.
After 0.25 is lost the total = $2.25.
So the new average = 2.25 / 5
= $0.45.
The answer is c, 32. QS and TV are congruent. You set them equal to each other. And find v, v is 6 and find QS, which is 32. Since they are congruent, both QS and TV are 32
To get the answer for this question is to:
Divide 56 by 72 = 0.777777778 because 0.777777778 * 72 = 56 cm.
Since 72 cm is related to the side length of 9 cm, take 0.777777778 and multiply it by 9 and you will get 7 for the missing side length.
To get the value of X for the equation to equal 7, take the 7 you got for the missing side length and add it to 20 to get 27 (20 + 7 = 27). Then, take the 27 and divide it by the 3, and you will get 9 for X.
Example:
7 + 20 = 27
27 / 3 = X
9 = 9
&
3x - 20
= 3(9) - 20
= 27 - 20
= 7
The correct answer for the value of X is: 9
Hope this helps!

Answer:
length = 11 ft, width = 6 ft
Step-by-step explanation:
Let w be the width, l be the length and p the perimeter. You can write down the following equations:
1. w = l - 5
2. p = 2*(w + l)
Now you have two equations with two unknown.
Plugging eq.1 in eq.2:
p = 2*(l-5 + l)
p = 2*(2*l - 5)
p = 4*l - 10
Remember p = 34
34 = 4*l - 10
4*l = 44
l = 11
Using eq.1 to solve for w:
w = 11 - 5
w = 6
