Answer: a) = 10
b) = 16
Step-by-step explanation:
a) as x = 5 so putting the value of x in given equation
5 multiplied by 2 is equal to 10
b) Putting value of x in given equation
= (5 + 3) 2
According to BODMAS solve the brackets first
= 8 x 2
= 16
Answer:
A is the cheapest deal.
Step-by-step explanation:
find unit rate; cost / quantity
20.20 / 10 = $2.02 per gallon
26.04 / 12 = $2.17 per gallon
28.24 / 24 = $2.01 per gallon
30.45 / 25 = $2.03 per gallon
Answer:2.50
Step-by-step explanation:
Well if your equation is 9=-2/3x-y, you’ll have to make it into y=Mx+b form first so subtract 9 from both sides and add y from both sides. your equation should be y=-2/3x-9. therefore you’re answer is 4.
7/9^2 is 49/81
