Answer: yes
Step-by-step explanation:
Answer:
(3x) ° + (x+ 10)° = 90°
Step-by-step explanation:
(3x) ° + (x+ 10)° = 90°
3x + x + 10 = 90
4x = 90 - 10
4x = 80
x = 20
(3x) ° = 3 x 20 = 60°
(x + 10)° = 20 + 10 = 30°
Answer:
9x + 4(x+2) - 5
9x + 4x + 8 - 5
13x + 3
Step-by-step explanation:
I hope this helps!
A
4+8=12 wrong
4.5+8=12.5 wrong
5+8=13 wrong
5.5+8=13.5 right
the rest of the numbers are above 5.5 so they aren't wrong
<u>5.5, 6 and 6.5 makes the inequality true
</u>
B
x+8>13
x>13-8
<u>x>5
</u>
C
<u>x=5 is not a solution to the inequality because 5+8 is not more than 13.</u>
X+y=?
Would be the equation i am pretty sure
