Answer:
 a taco is 1.25 and a drink is 0.95
Step-by-step explanation:
tacos = t
drinks = d
5t + 3d = 9.10
3t + d = 4.70
this is a simultaneous equation so times the first one by one and the second by 3 and then take them away from each other and solving to get
t = 1.25 and d=0.95
one drink is $0.95
one taco is $1.25
Hope this helps!!
 
        
             
        
        
        
A.


cost is $16.50
B.

rearrange to solve for t:

C. This is the same as part B, only the rate changed

they ask for the greatest number of minutes, so we round down (take the floor of the value).
the answer is 105 minutes.
 
        
        
        
Answer:
2x+1
Step-by-step explanation:
x = 1st integer
x+1 = next consecutive integer
The sum is
x+ (x+1)
Combine like terms
2x+1

(a) Without solving the equation we can't determine whether its true or false.
(b) If x = 3
 4x + 1 = 2x + 5
 4(3) + 1 = 2(3) + 5
 12 + 1 = 15 + 5
 13 = 20
No, if x = 3, the equation will not be true.
(c) 4x + 1 = 2x + 5
 4x - 2x = 5 - 1
 2x = 4
 x = 4/2
 x = 2
This shows that x = 2 makes the equation true.
