One way of attacking this problem would be to cross multiply:
(5/12)k = (5/3)(5/2)
(5/3)(5/2) 25/6 50/12
Solving for k: k = -------------- = ----------- = ------------ = 10 (answer)
5/12 5/12 5/12
Answer:
x ≤ 4
Step-by-step explanation:
Subtract 7 on both sides:
x + 7 ≤ 11
-7 -7
x ≤ 4
Okay, let me first explain what the equation<em> y = 8.77x + 686 </em>means
<em>y </em><em>is the hikers elevation </em>
Look at the graph and see what the y and x axis's are labeled as.
<em>x </em><em>is time. </em>
8.77 is just the slop of the trend line.
<em>686 </em><em>is just the elevation the hiker starts at</em>, or in technical terms, the y intercept. Y intercept is just where the lines touches the y axis.
The question asks what will be the <u>hiker's elevation at 145 minutes. </u>
To solve, just simply <u>plug in 145 as X </u>in the equation above. Remember x is time.
It will look like this :
y = 8.77 (145) + 686
Then solve.
y = 1271.65 + 686
y = 1957.65
Reminder: They want the nearest whole number!
Round 1957.65 feet to 1958 feet

Answer:
-62
Step-by-step explanation:
-2 + (6)(-10) = -2 -60 = -62
__
2 less than a product is 2 subtracted from the product, or -2 added to the product. A product is formed by multiplying the given numbers.
The product of 6 and -10 is 6×(-10) = -60. 2 less than that is -62.
I did this question wrong so I had to edit it.... sorry :s.
