Answer:

180 plants  

Step-by-step explanation:

the area of a right triangle is: ab/2

side a = 8

side b = 15

8 x 15 = 120

120/2 = 60

Michael wants 3 plants for every square yard (multiply by 3)

60 x 3 = 180

Answer:

180

Step-by-step explanation:

Height times width/2 equals the area of a triangle. 8 times 15 divided by 2 equals 60. 3 plants per square yard. 3 times 60 equals 180.

<span><u><em>Answer:</em></u>
Each will have passed 17 tests and it will take 3 weeks.

<u><em>Explanation: </em></u>
Let x be the number of weeks.
The number of tests <u>Travis</u> passes to begin with is 11.
We then add 2 tests per week, or 2x to that, giving us:
11+2x.

The number of tests <u>Jenifer</u> has passed to begin with is 2.
We then add 5 tests per week, or 5x to that, giving us:
2+5x.

<u>Setting these equal, we have: </u>
11+2x=2+5x.

<u>Subtract 2x from each side: </u>
11+2x-2x=2+5x-2x;
11=2+3x.

<u>Subtract 2 from each side: </u>
11-2=2+3x-2;
9=3x.

<u>Divide both sides by 3:</u>
</span>\frac{9}{3} =  \frac{3x}{3}<span>;
3=x.

It will take <u>3 weeks</u>.
In 3 weeks,
Travis will have passed:
11+2*3 = 11+6 = 17 tests.
Jenifer will have passed the same number, since she catches up with him at this point.</span>

Andrew answered 21 out of 25 questions correctly on his math test. Written as a decimal, what portion of Andrew's answers were c
soldier1979 [14.2K]
Since we are calculating the amount that he got correct, we must divide the numerator by the denominator or make the denominator equal 100. I will do it the second way as it is easier in this case.

25*4 = 100
21*4 = 84

84/100 = 0.84

As a decimal, Andrew got 0.84 of his test correct. Hope this helps!

zhuklara [117]

Answer: 5x - 1 = -6

Step-by-Step Explanation:

We have this diagram here showing numbers and symbols. Just a remainder, "X" is a variable which can be found through and equation of Algebra. Alright, so we have 5 boxes with the symbol "X". Alright, that's a start, so we have <u>5x</u> as a start of the equation. We have <u>-1</u> on the same side as well.

Alright, so on the other side- we have Six symbols of "-1".

That concludes to... <u>-6</u>. Alright, notice how all of the symbols are on a Scale, so we can heavily imply that the "=" symbol will take place between the two sets of symbols. Alright, combining them we get.. <u>5x - 1 = -6.</u>

<em>If you need further instructions/help, don't hesitate to give me a shout out. Bye, and I hope this helps.</em>
