Answer:
c tomato 2.5
pepper = 3.5
Step-by-step explanation:
Let t= the price of tomato plants
p =the price of pepper plants
3t+ 4p = 21.50
5t+ 2p = 19.50
Multiply the second equation by -2
-10t -4p =-39
Add this to the first equation to eliminate p
-10t -4p =-39
3t+ 4p = 21.50
---------------------
-7t = -17.5
Divide by -7
t = 2.5
Now find p
5t+ 2p = 19.50
5( 2.5) + 2p = 19.50
12.5+2p = 19.50
Subtract 12.5 from each side
2p =7
p =3.5
We want the price of 1 tomato and 1 p
3.5+2.5
Well, it went from 400 to 550, so the difference is 150.
if we take 400 to be the 100%, what is 150 off of it in percentage?
Answer:
#1) 4 x 3 - 1 is less than or equal to 11 (it's equal). 4 x 3 - 1 < 11 is not true because 11 is not less than 11.
Step-by-step explanation:
#2) 8x + 1 = 57 --- subtract 1 from both sides
8x = 57 - 1
8x = 56 -- divide both sides by 8
x = 7.....any other value for x will not work
Answer:
Step-by-step explanation:
It is unclear from the phrasing what dimension 8.2 ft represents.
If 8.2 ft is the direct distance from the edge of the roof to the top of the pitch, then the <em>horizontal</em> distance from the edge to the top is √(8.2²-2.4²) ≅ 7.84 ft, and the slope is 2.4/7.84 ≅ 0.31
If 8.2 ft is the <em>horizontal </em>distance from the edge of the root to the top of the pitch, then the slope is 2.4/8.2 ≅ 0.29
The x-value of the vertex of the given parabola is x = 5, so the correct option is b.
<h3>
How to get the x-value of the vertex?</h3>
If we define the parabola by f(x), by looking at the table, we can read:
So, notice that:
f(2) = f(8).
Then the x-coordinate of the vertex is the midpoint between 2 and 8.
x = (2 + 8)/2 = 5
The x-value of the vertex of the given parabola is x = 5, so the correct option is b.
