Let w = the width.
If length is 4 more than the width, then Length = 4 + w
35) Nine times the with
9 * w = 9w
36) Half the width
(1/2) * w = (1/2)w = w/2
37) The length
Already solved; it's 4 + w or w + 4. Because it's addition, it doesn't matter which one comes first.
the second 37? Your math teacher can't count?) Nine times the length
9 * (4 + w)
9(4) + 9(w)
36 + 9w
38) 2 less than nine times the width
(9 * w) - 2 = 9w - 2
Answer:
make sure that you are on time with all of your work. also start studying for a test that you have at least 3 days in advanced. you also should study in different ways. if you just study one way the test may not be in that format which will cause some stress. I hope that helps
Answer:The answer is 9 plants/1 row plants per row.
Step-by-step explanation:
6601/287=9
Let us say that:
a = ones
b = fives
c = twenties
So that the total money is:
1 * a + 5 * b + 20 * c = 229
=> a + 5b + 20c = 229 -->
eqtn 1
We are also given that:
c = a – 5 -->
eqtn 2
a + b + c = 30 -->
eqtn 3
Rewriting eqtn 3 in terms of b:
b = 30 – a – c
Plugging in eqtn 2 into this:
b = 30 – a – (a – 5)
b = 35 – 2a -->
eqtn 4
Plugging in eqtn 2 and 4 into eqtn 1:
a + 5(35 – 2a) + 20(a – 5) = 229
a + 175 – 10a + 20a – 100 = 229
11a = 154
a = 14
So,
b = 35 – 2a = 7
c = a – 5 = 9
Therefore there are 14 ones, 7 fives, and 9 twenties.
