Answer:
7 hours
Step-by-step explanation:
We have that the value of the review of a bicycle has the following function:
v = 14 + 9 * t
where t is the time in hours
if we know that Aara paid a total of 77, that is v = 77, we can calculate the value of t, replacing:
77 = 14 + 9 * t
solving for t:
t = (77 - 14) / 9
t = 7
that is to say that Sara left the bicycle in a total of 7 hours
3 hearts
4 triangle
H:T
3:4
So, ratio of hearts to triangles in simplest form is 3:4
(we can't simplify any further - HCF of 3 & 4 is 1)
Hope this helps!
The inequality is 7x + 21 
Step-by-step explanation:
<u>DATA:</u>
Let the number be x
Number times 7 = 7*x
Sum of a number times 7 and 21 = 7x + 21
Is at least 29
<u>INEQUALITY:</u>
7x + 21 
<u>SOLVE:</u>
7x
7x
x 
Therefore, the inequality is 7x + 21
