Answer: a= 96
Step-by-step explanation:
28^2 + a^2 = 100^2
784 + a^2 = 10000
-784 -784
a^2 = 9216
a= 96
Answer:
No, she's incorrect. 4x - 5.2y + 6y + 7.9x - 8x = 3.9x + 0.8y
Step-by-step explanation:
To find out if Esme is correct, we have to group the like terms and simplify.
As you can see, 3.9x + 0.8y is the correct simplified expression, thus making Esme incorrect.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Answer:
1) x = 30
2) x = 11.6
Step-by-step explanation:
1) 2x = 4x - 60 (vertical angles are equal)
subtract 4x from each side of the equation:
-2x = - 60
divide both sides by -2:
x = 30
2) 7x + 16 + 3x + 48 = 180° (supplementary angles add up to 180°)
combine like terms:
10x + 64 = 180
subtract 64 from both sides of the equation:
10x = 116
divide both sides by 10:
x = 11.6
Cant you figure this out just read it lol
