Answer:
x is greater than negative 4, and less than or equal to 5
Step-by-step explanation:
Step-by-step explanation:
4.
22+4x= 90
4x=90-22
4x=68
x°=17°
7.
(x-5)°+29°=180°
x-5+29=180
x= 180-24
x=156°
10.
(x+3)°+49°=90°
x= 90-52°
x=38°
Answer:
commutative property
Step-by-step explanation:
You switched the numbers inside the parenthesis, which in this case is 5 and -5.
The answer is A.
We can first eliminate D since it uses these (<, >) signs and the lines are shaded, indicating the points on those lines are solutions.
We can also eliminate C because the y intercept in C’s lines is 2, while in the graph, they are both 3.
Finally, we can look at both inequalities on the graph and see that the shaded areas are both underneath the line. This means that y is less than the equation for the line, eliminating B
So, the answer is A
Hope this made sense!!
Answer:
25 liters
Step-by-step explanation:
15x + 45(5) = 20(x + 5)
15x + 225 = 20x + 100
Simplify
125 = 5x
Divide both sides by 5
25 = x
25 liters
