Answer:
3 meals
Step-by-step explanation:
The card costs $6, so we will subtract that from $15 because it is the starting amount. Karla can't buy these meals for $3 without $6. Anyways, 15-6 is 9. Each meal costs $3 so we'll then divide 9 by 3, which gives us our answer: she bought 3 meals.
Answer: r=7x-1/8
Step-by-step explanation:
2(4r+3)=7x/2+5/2
4r+3=7x+5/2
4r+3-3=7x+5/2 -3
4r=7x+5/2 -3
4r/4= 7x-5/2/4 -3/4
r=7x-1/8

Answer: -2.8
Step-by-step explanation:
3t-(8/5) * 4-t < -7
(15t-8)/5 * 4-t < -7
((15t-8)(4-t))/5 < -7
(15t^2)-28t-32< -7
(15t^2)-28t-32-7< 0
(15t^2)-28t-39< 0
Using the quadratic/almighty formula
t= (-b +- ((b^2)-4ac)^(1/2)/2a)
a=15, b=-28, c=-39
t= (-(28) +- (((-28)^2)-4(15)(-39))^(1/2))/2(15))
t= -2.8 or t= 0.9
Since
t<0, then t= -2.8
