Answer:
4 x 1 = 4 x 3 = 12 = 4 x 3
Step-by-step explanation:
sorry I'm having trouble with this too
Let,
- Mass of the steel be 108x
- Mass of the copper be 7x
- Then, Total mass = 108x + 7x = 115x
Given,
- Total mass of the coin = 230 mg
That means,
⇛ Total mass of the coin = 230 mg
⇛ 115x = 230 mg
⇛ x = 230 mg/115
⇛ x = 2 mg
Then,
- Mass of the steel = 108(2) = 216 mg
- Mass of the copper = 7(2) = 14 mg
☁️ ANSWER - 14 mg (Mass of copper)

Answer:
4
Step-by-step explanation:
6m- 10= 22-2m
you take like terms.....the ones with an alphabet meets each other and the ones without an alphabet meet each other
6m- 10= 22- 2m
6m+2m = 22 +10
when a minus is crossing the equality sign it becomes plus and when plus is crossing an equality sign it becomes minus....Gotten?
so, lets solve
we will add
8m= 32
we will divide the numbers with the coefficient of the unknown which is 8
8m/8=m
8 divide 8 willl be 1 which is m and not 1m that is wrong in maths.....okay
8 divide 32 is 4
so we have our answer m=4
5×70=5×7=?tens=? sorry i didnt know all of them
