Answer:
If Michael has $2 and he spends $1, how much money does he have left? We can figure this out by subtracting $1 from $2. This is obviously equal to $1.
We can use the same idea for this problem. George starts with $23 and spends at least $14. After this, George has 23 - 14 = $9 dollars left. So, George can spend $9 at the max.
We can translate this into math words by saying George can spend less than 9 on glue, so p < 9. So, a. is the correct answer.
Step-by-step explanation:
Answer:
15 inches
Step-by-step explanation:
The perimeter of a polygon is the sum of the lengths of its sides. A square has 4 sides, all the same length. We can either add up the side lengths, or we can recognize that multiplication of one side's length by 4 is a useful alternative.
perimeter = 4 × (3 3/4 in)
= (4×3 +4×3/4) in
= 12 in + 3 in = 15 in
Answer:
The area of a triangle can be found using:
a=1/2 bh
or
a=(bh)/2
where b is the base and h is the height
We have by distributivity of limits over sums, and continuity of 
and 
, that
Given 
, it follows that
0.25x + 0.10y = 0.15*15
X + Y = 15
Y = 15 - X
0.25X + 0.10(15 - X) = 2.25
0.25X + 1.5 - 0.10X = 2.25
.15X = 0.75
X = 5
Y = 15 - 5
Y = 10
