Answer:
-3
Step-by-step explanation:
The statement is,
→ Sum of 9 and -16 increased by 4
The equation will be,
→ {9 +(-16)} + 4
→ (9 - 16) + 4
→ -7 + 4
→ [ -3 ]
Hence, the solution is -3.
1st element can be matched with 5
2nd element can be matched with 4
3rd element can be matched with 3
etc.
Total number of correspondences = 5*4*3*2*1 = 120
Answer:
6 pounds of green candy
Step-by-step explanation:
Let r be the weight of red candy
Let g be the weight of green candy
Total weight = 10 pounds
r + g = 10 -------------------------(I)
Total cost = $ 38.50
2.50r + 4.75g = 38.50 --------------(II)
Multiply equation (I) by -2.50
(I)* (-2.50) -2.50r - 2.50g = -25.0
(II) <u>2.50r + 4.75g = 38.50 </u> {Now add and r will be eliminated}
2.25g = 13.50
g =13.50/2.25
g = 6
Plug in the value of g in equation (I)
r + 6 = 10
r = 10 - 6
r = 4
