Answer:
c ≈ 5.5 cm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
c² = 2.4² + 4.9² = 5.76 + 24.01 = 29.77 ( take square root of both sides )
c = 
≈ 5.5 cm ( to the nearest tenth )
When multiplying them out you get:
6.0258
but rounded to the nearest hundredth you'd get:
6.03
⓵ You need to solve the left side first in order to isolate the × and find it’s value :
-7× + 6 = 27
-6 -6
↓
-7× = 21
÷-7 ÷-7
↓
× = -3
If you find it too difficult to divide a number by a negative, just divide 21 by 7 and always remember that when dividing, when the signs are different the answer is negative. So knowing that you could just divide 21 by 7, which is 3, and add a negative sign in front!
I hope this helped, if there’s anything let me know! ☻
