Answer:
Jumper, y = 172
Shirt, x = - 105
Step-by-step explanation:
Let :
Shirt = x
Jumper = y
5x + 4y = 163 - - (1)
3x + 2y = 29 - - - (2)
Multiply (1) by 3 and (2) by 5
15x + 12y = 489 - - - (3)
15x + 10y = 145 - - - (4)
Subtract :
12y - 10y = 489 - 145
2y = 344
y = 344 / 2
y = 172
Put y = 172 in (3)
15x + 12(172) = 489
15x + 2064 = 489
15x = 489 - 2064
15x = - 1575
x = - 105
The values ;
Jumper, y = 172
Shirt, x = - 105

Answer:
Use the formula for calculating compound interest PN=P0(1+rk)Nk where P0 is the unknown, PN=10,000, N=10, k=1, and r=0.015. Substitute the values into the formula and simplify.
10000=P(1+0.0151)1⋅10
10000=P(1.015)10
10000=P(1.16054...)
8616.67=P
Therefore, rounded to the nearest dollar, the initial investment needs to be $8617 to have $10,000 in 10 years.
Step-by-step explanation:
Answer:
s = -1
Step-by-step explanation:
7 = -10s -3 <== add 3 to both sides
+3 + 3
10 = -10s <== divide both sides by -10
/-10 /-10
-1 = s
Final answer: -1 = s or s = -1
Hope this helps!
