4x + 8z = 2. Solve for z
Answers
Step-by-step explanation:
4x + 8z = 2 Subtract 4x from both sides
8z = 2 - 4x Now, divide both sides by 8
z = (2-4x) / 8 or (1-2x) / 4

Answers
Answer:
A. 4.7 cm
Step-by-step explanation:
where the rectangles are similar, the ratios of the sides must be similar
Given that One has a length of 14 cm and a width of 9 cm, and the other has a width of 3 cm
let the length of the other rectangle be L
14/9 = L/3
L = (14 × 3)/9
= 14/3
= 4.66cm
≈ 4.7cm
The right option is A. 4.7 cm
Let's x the length of the second rectangle:
x/14=3/9==>x=14/3==>x=4.666666......

3/9 gallons = 1 hour
3 gallons = 9 hours
1 gallon = 9/3 hours
Therefore, It will use 1/3 gallons of water each hour and will use 1 gallon in 3 hours
Answer:
First find out the how many gallons of water does it use each hour .
To prove
As given
An ice machine uses 3 gallons of water every 9 hours.
3 gallons of water = 9 hours
Water uses by ice machine in one hours = 0.33 gallons (Approx)
Now find out how many hours does it take to use one gallon .
As given
An ice machine uses 3 gallons of water every 9 hours.
3 gallons of water = 9 hours
Hours take by ice machine to use one gallons of water = 3 hours.
x = 5
y = 7
x = 7
Answers
Answer:
y = 7
Step-by-step explanation:
x=4 is a vertical line that goes through the point x=4. y value of this graph changes while x value will be 4 at every point of the graph.
A line perpendicular to this will be a horizontal line with a fixed y value and the x value will change.
The coordinates of the point of which the line has to pass is given as (5,7). Which means the y coordinate of this line is 7.
As we have established that this line has to have same y value at each point just like x=4 has same x value at each point, we can say the equation of the line is y=7.
Solution:
Equation of line perpendicular to , x=4 is
y +k=0
As, keep in mind , the equation of line perpendicular to , ax + by +c=0 is b x - a y +c=0
As, given the line perpendicular to, x =4, passes through the point (5,7).
So, y+k =0, passes through (5,7).
→ 7 +k=0
→ k= -7
So, line perpendicular to x=4, which passes through the point (5,7) is →y-7=0 that is y=7.
Option (C) →y=7

Answer:
For me i think its 16.67 well im not fully sure
Step-by-step explanation:
SO we have to figure out what gives us 10 and that will be represented as "x"
× x = 10
Multiplying both sides by 100 and dividing both sides by 60,
we have x = 10 × so, x = 16.67
(that's what i believe but i don't know)
