Answer:
42
Step-by-step explanation:
4x + 2 = 1/2 (4x + 44) Be careful how you do this. I have multiplied both sides by 2
2(4x + 2) = 4x + 44 Remove the brackets (distributive)
8x + 4 = 4x + 44 Subtract 4x from both sides
8x-4x + 4 = 44
4x + 4 = 44 Subtract 4 from both sides
4x + 4-4 = 44-4
4x = 40 Divide by 4
4x/4 = 40/4
x = 10
The mid line is 4x + 2
The mid line is 4*10 + 2
The mid line is 40 + 2
The mid line is 42
The base is 4x + 44
The base is 4*10 + 44
The base is 40 + 44 = 84 which is twice the midline. I did this just to show it is twice as big as the midline.
It'll be x divided by two
Hope this helps :)
Answer:
x+11 = 5x - 5
Step-by-step explanation:
x+
11
=
5
x
−
5
Subtract x from both sides
11
=
4
x−
5
Add 5 to both sides
16
=
4
x
Divide both sides by 4
x=4
0.3 is 3/10, (which is already simplified) because .3 is out of 1. Which means that that 1 is 10. Which is 3/10.
128 pieces can be made after cutting the chain
<em><u>Solution:</u></em>
Given that, Amy cut 32 ft of chain into pieces that were each 1/4 ft long
<em><u>To find: Number of pieces after cutting the chain</u></em>
From given,
Thus the number of pieces after cutting the chain can be found by dividing the total length of chain by length of 1 piece
<em><u>Substituting the values, we get</u></em>
Thus 128 pieces can be made after cutting the chain
