Answer:
The total number of train tickets Aaron can buy=4
Step-by-step explanation:
a). Determine first expression
Let the number of each mode of transport be as follows;
bus ticket=b
train ticket=t
b). Determine the second expression
Let the total cost be expressed as shown;
total cost=(cost per bus ticket×number of bus tickets)+(cost per train ticket×number of train tickets)
where;
total cost=$520
cost per bus ticket=$64
number of bus tickets=b=3
cost per train ticket=$82
number of train tickets=t
replacing;
(64×3)+(82×t)=520
192+82 t=520
82 t=520-192
82 t=328
t=328/82=4
t=4
The total number of train tickets Aaron can buy=4
Answer:
1/2x +7
Step-by-step explanation:
Let the unknown number be x
We want 1/2 of the number
1/2x
Then 7 more than (add)
1/2x +7
<span>The question asks us to determine the values for a and b in the linear equation. Linear equation in the slope-intercept form is : y = a x + b. This equation is: y = 2.25 x - 3.15. The slope: a = 2.25 and the y-intercept is: b = -3.15. Answer: a = 2.25 and b = - 3.15.</span>
Answer:
the answer is e i think.
Step-by-step explanation:
A) Gavin’s drinks altogether cost £9.00
1.50+2.50x3
=1.50+7.50
