Answer:
a=2.25
Step-by-step explanation:
Given the equation 4.5=2a, you'd finds the value of "a" and divide both sides by 2.
4.5/2=a
2.25=a
a=2.25
Answer:
-1
Step-by-step explanation:
9(x+2)=5−2(x−1)
9x+18=5−2(x−1)
9x+18=5−2x+2
9x+18=7−2x
9x+18+2x=7
11x+18=7
11x=7−18
11x=−11
x= 11
/−11
x=-1
Hello Kiddo.
This question is a bit confusing to me, but I think I grasped the concept.
1. x best represents Sarah's mom's age.
2. x - 24 best represents Sarah's mom's age minus how much younger Sarah is than her mom.
3. The expression would look a little like this:
2x-24 = 68
+ 24 +24
2x = 92
/2 /2
x = 46.
Which means, Sarah is 22 and her mom is 46 years of age.
If you need more clarification, I'd be more than happy to elaborate further.
Answer:
1. x > 17
Step-by-step explanation:
When the point on the graph is an open circle you are going to be using < or > as an open circle means greater than or less than
Immediately we can eliminate number 3 and 4
When the line is going in the direction of the right than the inequality sign will face the variable (x)
the numbers are getting larger meaning that x is greater than the constant (17)
Hence, your answer is x > 17
Extra notes:
when the point on the graph is a closed circle ( filled in ) then you will use ≤ or ≥ as a closed circle means greater than or equal to or less than or equal to
This is a really hard question.
