Answer:
4 bottles
Step-by-step explanation:
Given


Required
Determine the number of bottles
Represent the number of bottles with N
<em>This implies that N bottles of </em>
<em> fit into </em>
<em> of fertilizer. The relationship between them is:</em>
<em></em>


Multiply through by 8




<em>Hence, there are N = 4</em>
Answer:
y = -5x - 17
Step-by-step explanation:
Linear equations, or lines, that are perpendicular to each other have opposite reciprocals for the value of slope. For the given line, y = 1/5x - 2, the slope is 1/5 and the opposite reciprocal is -5.
Given the value of the slope and a given point on the second line, you can solve for 'b':
y = mx + b
8 = (-5)(-5) + b
8 = 25 + b
-17 = b
y = -5x - 17
Answer:
x= -2, y = -3
Step-by-step explanation:
1. substitute x = 4+2y in the first equation: 
simplify it : 
2. isolate y in 8 + 5y = -7 --> 5y = -7 - 8 -->
3. solve for y: 5y = -15 --> y = -15/5 --> y= -3
4. solve for x: x = 4 + 2y
x = 4 + 2(-3)
x = 4 + (-6)
x = -2
Answer:
They add up to 720 degrees
Answer:
D). 
Step-by-step explanation:
<u>STEP 1a:</u> Find the last angle of the triangle. ( which is angle A)

<u>STEP 1b:</u> Solve the equation for A by adding 90 and 45.

<u>STEP 1c:</u> Then Move all terms not containing A to the right side of the equation by subtracting 135 from both sides of the equation

<u>STEP 1d:</u> Subtract 135 from 180.

STEP 2a: Find side b next.
STEP 2b: The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.

STEP 2c: Substitute the name of each side into the definition of the cosine function.

STEP 2d: Set up the equation to solve for the adjacent side, in this case b.

STEP 2e: Substitute the values of each variable into the formula for cosine.

STEP 2f: Cancel the common factor of 2.
