Answer:
The ratio of flour to sugar is 2:1
Step-by-step explanation:
Let f = weight of a bag of flour
Let s = weight of a bag of sugar
3f+2s = 32
4f = 32
We have 2 equations and 2 unknowns, we can solve
4f=32
Divide by 4
4f/4 = 32/4
f = 8
Each bag of flour weights 8 pounds
Substitute this back into the first equation
3(8) +2s = 32
24+2s = 32
Subtract 24 from each side
24-24 +2s =32-24
2s = 8
Divide by 2
2s/2 = 8/2
s = 4 pounds
Flours weighs 8 pounds and sugar weights 4 pounds
We want the ratio of flour to sugar
Flour: sugar
8:4
We can divide each side by 4
8/4: 4/4
2:1
Answer:
Part A: Option C
Part B: Option B
Step-by-step explanation:
Part A:
We have to find the equation of a straight line having x-intercept at (3,0) and y-intercept at (0,2).
Now, using intercept form of straight line equation we can write the equation of the required straight line is
⇒
⇒
So, option C is correct. (Answer)
Part B:
See the graph of the straight line provided.
The straight line passes through the points (10, 80) and (20, 100)
Therefore, the slope of the straight line is given by
therefore, option B is correct. (Answer)
Answer:
x=22
Step-by-step explanation:
(5x+4)+44+x = 180. reason [being co-interior angle)
48+6x = 180
6x = 132
x=22
