That means that 4 out of 11 people did not have umbrellas
You can write this as a fraction so
4/11 = x/99
Then, multiply both sides by 99 to isolate the variable.
So x is going to equal 99 times 4 divided by 11, which is 36. That means 36 people did not have umbrellas.
Answer:
x = 1, y = -4
Step-by-step explanation:
7х + 2y = -1 ------ eq1
3х — 4y = 19 ------ eq2
multiply eq1 by 2
2 x (7х + 2y = -1)
14x + 4y = -2 -----eq3
by elimination, add equation 2 and 3
14x + 3x = 19-2
17x = 17 (divide both sides by 17)
x = 1 (answer)
substitute into eq1
7(1) + 2y = -1 (subtract 7 from both sides)
2y = -1 -7
2y = -8 (divide both sides by 2)
y = -8/2 = -4 (answer)
I think the 57 is an whole number.
Answer:
on the second day it took them 6 hours to get to their grandparents' house
Step-by-step explanation:
First we have to calculate how many miles they had to drive the second day
For this we have to subtract from the total miles the number of miles they drove the first day
843 mi - 483 mi = 360 mi
To calculate the time it takes we have to divide the distance it has to travel by the average velocity at which they travel
v = 60 mi/h
d = 360 mi
t = d/v
t = 360(mi) / 60(mi/h)
t = 6 h
on the second day it took them 6 hours to get to their grandparents' house
Answer:Multiply the denominator on the bottom of the fraction by the whole number you are dividing by.
To divide a fraction by a whole number, multiply the bottom of the fraction by this whole number.
The denominator on the bottom of the fraction is 7.
We will multiply 7 by 2.
7 × 2 = 14 and so, 6 / 7 ÷ 2 = 6 / 14 .
