Solve these asap! solve for x. 1. 2(3x+5)=46 2. (1/2)x+(1/4)x=16 3. 6-x-x=18 4. 4x-(3/5)=(2/5) 5. x-13+4x=22 6. -36=(-6)(2x-14) 7. 2+(x/10)=(2/5) 8. you are ordering pizzas for a party and getting them delivered to your house. you order 12 pepperoni pizzas, 8 cheese pizzas, and 4 hawaiian pizzas. there is a delivery fee of $5.50. if your total comes to $184.54, how much does each pizza cost individually. assume the cost is equal for all kinds of pizzas. you!

my guess is

step-by-step explanation:

i suppose it should be (y=2x-5)

step-by-step explanation:

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
