The value of y varies directly with x. If x = 15, then y = 12. What is the value of y, when x = 21?
A.26.25
B.16.8
C.0.8
D.1.25
Answer:
The answers A
Step-by-step explanation:
Use ratios such that x1/y1= x2/y2
Need to find x2
So it works much easier if you use x as the numerator, giving 15/12=x/21
Multiply both sides by 21 and we have 21 x 15/12=x x 21/21
and 21/21=1 giving: x=21 x 15/12= 26 1/4
and in decimal form is 26.25

Details: Cargo ship can carry 21,600 tons Cars weigh 3.6 tons each Trucks weigh 7.5 tons each y = number of cars x= number of trucks Your equation was 3.6y + 7.5x = 21600 Find the number of trucks that can be shipped if there are no cars.
Given:
The equation is
[tex]3.6y+7.5x=21600[/tex]
where, y is the number of cars and x is the number of trucks shipped.
To find:
The number of trucks that can be shipped if there are no cars.
Solution:
We have,
[tex]3.6y+7.5x=21600[/tex]
If there are no cars in the cargo ship, then y = 0 because y is the number of cars.
Putting y=0 in the given equation, we get
[tex]3.6(0)+7.5x=21600[/tex]
[tex]0+7.5x=21600[/tex]
[tex]7.5x=21600[/tex]
Divide both sides by 7.5.
[tex]x=\dfrac{21600}{7.5}[/tex]
[tex]x=2880[/tex]
x is the number of trucks shipped.
Therefore, the number of trucks that can be shipped if there are no cars is 2880.

Layla has $2 worth of dimes and quarters. She has 6 more dimes than quarters. By
following the steps below, determine the number of dimes, I, and the number of
quarters, y, that Layla has.
Answer:
Layla has 4 quarters and 10 dimes
Step-by-step explanation:
A quarter each is 25 cents. And a dime each is 10 cents. counts from 10 10 times and then add 25 4 times and you get 200 which is 2 dollars. Example: 10 20 30 40 50 60 70 80 90 100 with 10 dimes alone that's a dollar 4 quarters equal another dollar so both of those equal 2 dollars. Layla had 4 dimes and 4 quarters when she added 6 more dimes it all equaled 2 dollars. Hopefully this makes sense.
proving answer:
10 - 4 = 6
Theres 6 more dimes than quarters

Step-by-step explanation:
The value after divide will be 2³ or 8.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The expression is,
⇒ 2⁹ divided by 2⁶.
Now,
Since, The expression is,
⇒ 2⁹ divided by 2⁶.
Hence, We get;
⇒ 2⁹ / 2⁶ = 2⁹⁻⁶
= 2³
= 8
Thus, The value after divide = 2³ or 8.

Explain how you would find 36x 5/6
mentally.
Answer:
In step-by-step explanation.
Step-by-step explanation:
Multiplying a fraction (like 1/2) is really just dividing by the denominator.
In this case, we can (mentally) divide 36 by 6.
36/6 = 6
So each 1/6 of 36 is 6.
Then we just add 1/6 of 36 five times to get 5/6
6+ 6+ 6+ 6+ 6 (or 6 x 5) and we get 30.

Answer:
x = 18
m<A = 166°
Step-by-step explanation:
The parallel lines are cut by a transversal, so corresponding angles A and B are congruent.
7x + 40 = 3x + 112
4x = 72
x = 18
m<A = 7x + 40 = 7(18) + 40 = 126 + 40 = 166
7x+40 = 3x+112
x=18
7(18)+40
<A = 166

Answer:
y = 24
Step-by-step explanation:
The line marked 'x' is a midline of the triangle, hence half the length of the parallel base line marked '4x-7'. This lets us solve for x and find the lengths of the sides of the triangle.
2x = 4x -7
7 = 2x . . . . . add 7-2x
3.5 = x
Then the horizontal side of the triangle is ...
4x -7 = 4(3.5) -7 = 7
The hypotenuse of the triangle is ...
6x +4 = 6(3.5) +4 = 25
The Pythagorean theorem can be used to find y:
y^2 +7^2 = 25^2
y^2 = 625 -49 = 576
y = √576
y = 24
5x + 2y = -3
3x + 3y = 9
Answer:
Step-by-step explanation:
5x + 2y = -3
3x + 3y = 9
15x + 6y = -9
-15x - 15y = -45
-9y = -54
y = 6
5x + 2(6) = -3
5x + 12 = -3
5x = -15
x = -3
