Answer:
see explanation
Step-by-step explanation:
let t be the cost of 1 t- shirt and s be the cost of 1 pair of shoes , then
4t + 3s = 325 → (1)
2t + 2s = 194 → (2)
(b) Solving by elimination
Multiplying (2) by - 2 and adding to (1) will eliminate t
- 4t - 4s = - 388 → (3)
Add (1) and (3) term by term to eliminate t
0 - s = - 63
- s = - 63 ( multiply both sides by - 1 )
s = 63
Substitute s = 63 into either of the 2 equations and solve for t
Substituting into (2)
2t + 2(63) = 194
2t + 126 = 194 ( subtract 126 from both sides )
2t = 68 ( divide both sides by 2 )
t = 34
Cost of pair of shoes = AED 63 and cost of t- shirt = AED 34
Answer:
2 hrs and 32 mins
Step-by-step explanation:
Step 1. Because Inez worked more we are going to start by subtracting the the minutes. 23-51= -28.
Step 2. Now we move on to the hours. 7-4= 3. Know we know that the hour time is going to be three. But wait!
Step 3. Because we can't have negative numbers, we need to subtract some more. 60-28= 32. Now I know that my minutes will be 32.
Step 4. But because we used a negative number we have to subtract another hour from our time.
Answer: 2 hrs and 32 mins
Hope this helps!
Answer: -12
