Answer:  x= 1 and y =1

Step-by-step explanation:

The given system of equation is :

5x - 4y = 1-------(1)\\\\2x + 3y = 5----------(2)

Multiply 2 to equation (1) and 5 to equation (2) , we get

10x-8y=2-------------(3)

10x+15y=25-----------(4)

Subtracting equation (3) from equation (4), we get

15y+8y=23\\\\\Rightarrow\ 23y=23\\\\\Rightarrow\ y=1

Substitute, the value of y in (1), we get

5x - 4(1)= 1\\\\\Rightarrow\ 5x=1+4=5\\\\\Rightarrow\ x=\dfrac{5}{5}=1

Hence, the solution of the given system is (x,y) = (1,1)

Find the distance speed=72km/h time=45mins
butalik [34]

The distance is 54 km if the speed and time are 72 km/h and 45 minutes respectively.

<h3>What is distance?</h3>

Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.

We have:

Speed = 72 km/h

time = 45 mins = 45/60 = 0.75 hours

We know,

Distance = Speed×time

Distance = 72(km/h)×0.75(h)

Distance = 54 km

Thus, the distance is 54 km if the speed and time are 72 km/h and 45 minutes respectively.

A number divided by 43 has a quotient of 3 and a remainder of 28. Find the number
svp [43]
You are given the unknown number which has a quotient of 3 and a remainder of 28. This means that 3 is the whole number from the division of the unknown number and 43 and 28 is the decimal, 3.28. Also, the number is divided by 43 too. Let us denote n as the number so we have n/43. Then equate the n/43 to 3.28.  

n/43 = 3.28
n = 43 (3.28)
n = 141.04
