Answer:
I will answer in a general way because the options are not given.
We know that the area of model A is smaller than the area of model B.
For model A, we have 72 shaded sections, out of 100.
Then the quotient of model A is:
72/100 = 0.72
For model B we have 10 sections, and x shaded ones.
Because model B is greater than model A, we know that:
x/10 should be larger than 72/100
then we have the inequality:
x/10 > 0.72
x > 0.72*10
x > 7.2
And we can not have more than 10 shaded sections (because there is a total of 10 sections) then:
10 ≥ x > 7.2
Then x can be any whole number in that interval.
the possible values of x are:
x = 8
x = 9
x = 10
Ok did your teacher say anything about not being able to use negative numbers or fractions? If not can you use fractions or negative numbers.
C=3 that’s the answer I think
You would need the departure time of each vehicle to know exactly when they would be 363 miles apart from each other so there is no way to tell when they would be 363 miles apart
Answer:
They are 3, 11 and 55.
Step-by-step explanation:
x +y + z = 69
y = x - 8
z = 5x
Substitute z = 5x in the first equation:
x + y + 5x = 69
6x + y = 69.........(1)
From the second equation
-x + y = -8.........(2)
Subtract equations (1) - (2):
7x = 77
x = 11
So z = 5x = 5*11 = 55 and
y = x - 8 = 11 - 8 = 3..
