The last time David filled up his truck with gas, he paid $27.44 for 7 gallons. This time, he needs 15 gallons. If the price is the same, how much will he pay?
Answer:
60% decrease
Step-by-step explanation:
150/100(%)=1.5
60/1.5=40(%)
100(%)-40(%)=60(%)
Answer: y = -12x +20
Step-by-step explanation: 1. distribute the -12 into the (x-2), that equals -12+24
2. subtract the 4 from the left side to move it to the right side of the equation
3. add like terms, so 24 + (-4) or 24-4 which equals 20.
4. Answer: y=-12x+20
1) A = (14)(24.5)-7^2
= 294m^2
2) A = (6)(7)+(17)(11)/2
= 135.5in^2
3) A = (8)(8)+(8)(4)/2
= 80cm^2
4) A = (7.5)(10)+(7.5)(5)/2
= 93.75cm^2
5) A = (18)(14)-9^2
= 171in^2
