Aunit of electricity costs 13.2 pence. on average, tanya uses 90 units of electricity per week. she pays for her bill in 12 weeks. how much will her electricity bill be then?

Her electricity bill will be of 14256 pence.

Explanation

On average, Tanya uses 90 units of electricity per week.

So, the total units of electricity in 12 weeks will be: units

One unit of electricity costs 13.2 pence.

Thus, the total cost for 1080 units will be:   pence.

So, her electricity bill will be of 14256 pence.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
