Answer:
He has 4 10/12 wire left
Step-by-step explanation:
Her electricity bill will be of 14256 pence.
<em><u>Explanation</u></em>
On average, Tanya uses 90 units of electricity per week.
So, the <u>total units of electricity in 12 weeks</u> will be:
units
One unit of electricity costs 13.2 pence.
Thus, <u>the total cost for 1080 units</u> will be:
pence.
So, her electricity bill will be of 14256 pence.
The answer is A
You can solve this by equation the two equations, by substitution method or elimination. Let's choose the substitution since Equation 2 has already X isolated
-take the X in equation 2 and substitute in the first equation
So, You should have 5 (5-3/2 y) -4y =7
Get y ( I'll assume you know how to simplify and find y by yourself )
y=36/23
-Now take y and substitute it in the first equation or the second equation (it doesn't really matter)
Substituting y in Equation 2:
x=5- 3/2 (36/23)
=> x= 61/23
So answer is A where (x,y) is (61/23, 36/23)
The numbers after the decimal place are represented as 10ths, hundredths, thousandths, and so on. 0.6 is said as "Zero point six tenths." Or "Zero and six tenths."
0.06 is said as "Zero point zero six hundredths." Or "Zero and six hundredths."
