Answer:
x = (W - y)/3
Step-by-step explanation:
3x+y=W
3x = W - y
x = (W - y)/3
Arturo will have 12 pieces. For this problem, you need to multiply by the reciprocal. To do that, you flip 1/3 over to 3/1 and multiply that by 4. 3/1 times 4 equals 12. Remember that 4 as a fraction is 4 over 1. So you would multiply 4 by the numerator (3) because 4 is the numerator in 4/1.
We let x the distance traveled by Car A and y the distance traveled by car B. The speed of car A can be represented as x/2.4 and for Car B is y/4. From the statement given, we can write an equation relating the speed of both cars.
x/2.4 = 22 + y/4
Since y = x, then:
x/2.4 = 22 + x/4
Solving for x, we obtain:
x= 132 meters traveled by both cars
Therefore, Car A has a speed of 55 mph.
Answer:
Similar triangles states the length of the corresponding sides are in proportion.
In a given similar triangles:
Labelled the diagram:
Triangle BAC and triangle DAC are similar.
then;
Corresponding sides:
AB = x units , BC = 5 units, AD = 15 units and DC = BD-BC = 8-5 = 3 units
By cross multiply we get;
Simplify:
Divide both sides by 3 we get;
Simplify:
x = 25 units
Therefore, the value of x is 25 units.
Answer:
35x-45y-20
Step-by-step explanation:
-5(-7x+4+9y)
distribute the 5:
35x-20-45y
To put this in order, variables first so:
35x-45y-20
Hope this helps:)
