Brainliest when you can if you will!!!!
100-30=70-50=20
there's your equation
Answer:
Step-by-step explanation:
1.2m = 120 cm
2.16 m = 216cm
120×216 =25920cm
2) 10×18 = 180
25920/180= 144
√144 = 12
For this equation, we can let c = the value of one coupon
<span>4c = 108 - 76 </span>
<span>4c = 32 </span>
<span>c= $8
Hope this helped, and if it did I'd appreciate if you marked me as brainliest as I need it to get to a higher rank. If you need any more help, feel free to add me and/or message me :)
