Answer:
Step-by-step explanation:
1) 1 km = 1000 m
7.8 km = 7.8 * 1000
= 7800 m
2) 1 g = 1000 mg
1.6 g = 1.6 * 1000
= 1600 mg
B) 6 ounces
not 100% sure though
3 - 2 + x + 436 123/157 =
1 + x + 436 123/157 =
437 123/157 + x =
68732/157 + x
Answer:
One clay block = x = $2.50 from before.
One mold = y = $4.00
Step-by-step explanation:
Multiply the second one by -2 to get -12x-2y=-38.00
Add these equations to eliminate y:
-12x-2y=-38.00
3x+2y=15.50
Result: -9x+0y=-22.50
9x=22.50
x=$2.50
