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: 13x+3y-3+y^2
Step-by-step explanation:
(7x+6x)+3y+(-2-1)+y^2
13x+3y-3+y^2
Answer:There is not a graph
Step-by-step explanation:
The answer is (B). g-6 because your taking away 6 raisins.
+(-x) = -X
+(-7) = -7
So
6-x+2x-7+2x
Simplifies to
3x-1
So your answer is 3x-1
Hope this helps
