Answer: X+10
X+10
Explanation:
Break down the information given to you to try and identify what the algebraic expression must looks like. You know that you're dealing with
a sum
→
this means that you are adding something, so you're going to use the
+
sign;
of a number
→
this means that you're dealing with a variable. The most common notation for a variable is
x
.
and 10
→
this is simply an integer that must appear in the algebraic expression along the variable
x
.
So, put all this together to get
x
+
10
You're adding an unknown number,
x
, to an integer,
10
The question can be answered using ratio and proportion.
In 40 minutes, Tracy can rake 4 bags of leaves. In 2 hours (which is equivalent to 120 minutes), how many bag will it be?
Making the equation.
4 : 40 = BAGS : 120
4 x 120 = 40 x BAGS
480 = 40 (BAGS) // Divide both sides by 40
BAGS = 12.
So there will be 12 bags of leaves.

Answer:
A. 5 + 2.75 · S ≤ 21
Step-by-step explanation:
So we know that it has to be less than or equal to $21 because that's all she has to spend. So we can automatically rule out the equations with ≥ because that means greater than.
We can also rule out the equations that have 50 at the very end because that's just how far she wants to travel.
