Multiply the denominator by what you're dividing.
In this case we take the denominator of 1/5 (5) and times it by 8.
Me rearrange the product to the denominator and get...
1/40
We know that total bill = rate per gallon times numbers of gallons used
So 17.60 = 0.55 times g
which get match to option (a) this is correct .
Now if we divide both sides by 0.55 we would be getting :
17.60 / 0.55 = g which is slightly different than option (b) ( because it is 55 in option b but actually it should be 0.55) so this one is incorrect .
let us now come back to option (a) 17.6 = 0.55 g
if flip the sides it becomes 0.55g = 17.6 which is same as option c option c is also correct .
Let us now divide both sides of option a by g^2 which makes it
17.6/ g^2 = 0.55 /g or 0.55/g = 17.6 /g^2 which matches only left side of option d but not right side of it so this is also not a correct option
Answer : only (a) and c are correct answer .
Answer:
W = 20 (woman's age)
M = 60 (man's age)
Step-by-step explanation:
M = Man's age
W = Woman's age
M + 20 = 2(W + 20)
Sub for M
3W + 20 = 2W + 40
W = 20 (woman's age now)
M = 60 (man's age now)
Answer:
11
Step-by-step explanation:
378 / 18 = 21 // Money p/h
231 / 21 = 11
Hello!
To find the line perpendicular to the given line, y = 2x + 3, firstly, find the slope of the perpendicular line. To find it, use this format: -1/m, where m is the slope. It is also called the "negative reciprocal" of the slope of the given line.
Then, you substitute an ordered pair into a new slope-intercept equation (with the slope) and find the y-intercept.
-1/m when m = 2 → -1/2
y = -1/2x + b (substitute the given ordered pair)
-3 = -1/2(2) + b (simplify)
-3 = -1 + b (add 1 to both sides)
-2 = b | The y-intercept of the perpendicular equation is -2.
Therefore, the line perpendicular to the given equation, that also goes through the given ordered pair is y = -1/2x - 2.
