If we represents a book's cost as x, that would mean that 5*x would represent the cost of 5 books (as x+x+x+x+x=5x) and 4x would be 4, resulting in 5x+4x=9x. After that, we get that 19 books is 19x as the cost, but since Agnus gets a 10 dollar discount, it's 19x-10. After that, to combine the two, we notice that Agnus still spends 5$ more than what they spent combined (9x) so we get that 9x+5=19x-10. Subtracting 9x from both sides, we get 10x-10=5. Adding 10 to both sides there, we get 10x=15 and we can divide 10 by both sides to get x=1.5
well, if the water is coming out at 0.44 ft³ per minute, and you take a shower for 8 mins, that simply means you used 8*0.44 ft³, or namely 3.52 ft³.
what if you instead fill the bathtub with 0.45 yd³? is that more or less than 3.52ft³?
so then, there are that many ft³ in a yd³, so how many will there be in 0.45yd³ anyway?
well, then you'd use more water with the 0.45yd³ and some soap btw, by how much more? 12.15 - 3.52 = 8.63 ft³.
Answer:
Step-by-step explanation:
if quadratic
(-3)²+5=9+5=14
so f(x)=x²+5
or
if linear
(-3)+17=14
f(x)=x+17
if cubic
(-3)³-2(-3)²-3(-3)+14=14
f(x)=x³-2x²-3x+14
so on.
Answer:
34
Step-by-step explanation:
25.5 (25 1/2) divided by 0.75 (3/4) = 34
hope this helps :3
