To solve this first we have to find out how many seconds are in 15 minutes.
So, 15 x 60 since there is 60 seconds in a minute, and of course there are 15 minutes.
15 x 60 = 900 seconds.
Now we need to find out about how many seconds does it take George to blink once. So we divide 900 seconds by 85 blinks.
900 / 85 = About 11 seconds for one blink.
Now we use the rate of 1 blink = 11 seconds and multiply. Since they said 51 blinks you would multiply 51 blinks by 11 seconds.
51 x 11 = About 561 seconds.
Answer: About 561 seconds passed in 51 blinks.
Answer:
<em>x is 12 and y is 3</em>
Step-by-step explanation:
Given a parallelogram LMNO,
LM = ON and OL = NM
Given;
ON = 9x - 8
LM = 8x + 4
NM = x - 8, and
OL = 3y - 5
Substitute into the expression
LM = ON
8x + 4 = 9x - 8
8x - 9x = -8 - 4
-x = -12
x = 12
Also OL = NM
3y - 5 = x - 8
3y - 5 = 12-8
3y - 5 = 4
3y = 4+5
3y = 9
y = 9/3
y = 3
<em>Hence the value of x is 12 and y is 3</em>

1. Answer: x < –4
The question is a bit ambiguous since x4 can be interpreted as x^4. Since there was no option for −x^4−6 ≥ −8 , I will solve the question assuming that the original question was −x(4−6)≥−8
−x(4−6)≥−8 −x(-2)≥−8 ---> multiply x with -2 2x≥−8 ----> divide by 2x≥−4
2. Answer: x≥ -11
To solve inequality using > or < sign, you must be careful because multiplying the inequality with -1 will cause the sign to change direction(< will become > or vice versa). In this case, will solve the question without multiplying it with -1
6.7 ≥−0.2x + 4.5 ----> move -0.2x to left, 6.7 to right
0.2x ≥ 4.5 - 6.7
0.2x ≥ -2.2
x≥ -11
Hello, well there are a few ways to write this. Here is one outlook.
Bruce bought three boxes of tiles with the same number of tiles in each.
x = number of tiles
3 = number of boxes
3x = total number of tiles.
Make note, the problem is asking for an expression for how many tiles he used and not the total number of tiles he has. Anyways, the problem then tells us he had to go get 3 more boxes but he used only 2 tiles out of the last box. So he used 2x + 2 tiles We put this together and we have
3x + 2x + 2
5x + 2
Number of tiles Bruce used = 5x + 2
We do the same for Felicia:
She gets 5 boxes, which = 5x. Then she had to go back and just get 5 tiles. So we have:
5x + 5
Number of tiles Felicia used = 5x + 5
