140 = 10x + 5y
24 = x + y
x = 4
y = 20
x is the number of $10 bills (So 4 $10 bills)
y is the number of $5 bills (So 20 $5 bills)
Answer:
Here is a graph I created.
For Miguel to spend the least amount of money, he would have to buy 2 gallons for $5.98 and two 1/2 gallons for $4.20. The total is $10.18.
I'm stuck on the next question though.
sin 57° = h/14, h=11,74.....
Area = h*20 = 234,82.... (cm²)
Answer:
It should be -5/2 for the points (-6,8) (-16,33)
Step-by-step explanation:
A diagram would be nice. If this is a right triangle, and one acute angle is 53 deg, then the other is 37 deg. You don't specify any dimensions, so all you can do is use theoretical values here.
If x is opposite the 53 deg angle, and the length of the hypotenuse is h, then side x has length h(sin 53 deg) = 0.799h.
