4. 3.75x + 3.7 = 1.7 + 1.75x
a) 10
b) –1
c) 1
d) .1 <-----------------------------
7. p + 4 < –24
a) p < –20
b) p < 28
c) p < –28 <------------------------
d) p < 20
To solve the given equations, let's go step by step:
4. 3.75x + 3.7 = 1.7 + 1.75x
Start by simplifying the equation by combining like terms:
3.75x - 1.75x = 1.7 - 3.7
2x = -2
Next, isolate the variable "x" by dividing both sides of the equation by 2:
x = -2/2
Simplifying further, we get:
x = -1
Since the given options are 10, -1, 1, and .1, the correct option is b) -1.
Now, let's move to the second equation:
7. p + 4 < -24
Subtract 4 from both sides:
p < -24 - 4
p < -28
Therefore, the correct option is c) p < -28.
4. 2x = -2
7. correct
