Answer:
t≥-25
Step-by-step explanation:
this is becuaset ≥ -25 shows that it can not fall under -25, but can be equal to -25.
Try 18mm that should be the answer
Answer:
b
Step-by-step explanation:
Y = 2 because half of 10 is 5 so half of 4 is 2
Answer:
the student solved the equation incorrectly because the original equation has one solution
Step-by-step explanation:
1/8(40x + 16) = 9x − 7(2x − 1) − 5
<em>use the distributive property a(b + c) = ab + ac</em>
(1/8)(40x) + (1/8)(16) = 9x + (-7)(2x) + (-7)(-1)
5x +2 = 9x − 14x + 7 − 5 <em>combine like terms</em>
5x + 2 = (9x - 14x) + (7 - 5)
<em>here the student make mistake 9x - 14x = 5x</em>
5x+2=-5x+2 <em>add 5x to both sides and subtract 2 from both sides</em>
5x + 5x + 2 - 2 = -5x + 5x + 2 - 2
10x = 0 <em>divide both sides by 10</em>
10x/10 = 0/10
x = 0
