Answer:
The numbers are 4 and 1
Step-by-step explanation:
Let x and y be the numbers
Quotient is division
x/y = 4
x-y =3
Taking the first equation and multiplying each side by y
x = 4y
Replacing into the second equation
4y -y = 3
3y = 3
Divide by 3
3y/3 = 3/3
y=1
Now we can find x
x -y =3
x-1 =3
Add 1 to each side
x= 4

Answer:
4/5 + 3/4 =
or 1.55
Step-by-step explanation:
This can be solved by first finding the highest common factors of denominators of the two fractions, i.e. 4 and 5.
The highest common factor of 4 and 5 can be found by multiplying the two numbers as follows:
The highest common factor of 4 and 5 = 4 * 5 = 20
This can now be used to solve 4/5 + 3/4 as follows:
4/5 + 3/4 = ((4 * 4) + (5 * 3)) / 20 = (16 + 15) / 20 = 31 / 20 =
or 1.55
Therefore, we have:
4/5 + 3/4 =
or 1.55

b i think im wrong but i tried..
Step-by-step explanation:
Answer:
CN Tower = 550 m and church tower = 160 m
Step-by-step explanation:
The first equation x + y = 710 is correct
but the second one is
x - y = 390
Note x = height of the CN tower and y = height of the church.
x + y = 710
x - y = 390
If we add the 2 above equations we eliminate y so
2x = 1100
x = 550 m
and y = 710 - 550 = 160 m
