This shows that Marco can buy at most 5 pencils
<h3>Inequalities</h3>
- Let the price of each pencil Marco can buy be "x"
If the cost of markers is $4, and the cost of each lead pencil is $3 with at most $15 spent, hence;
Subtract 4 from both sides
3x ≤ 15
x ≤ 15/3
x ≤ 5
This shows that Marco can buy at most 5 pencils

Answer:
UV=142
Step-by-step explanation:
21x-13=10x+31
+13 +13
21x=10x+44
-10x=-10x
11x=44
÷11 ÷11
x=4
now substitute 4 in place of x (only have to solve one)
21(4)-13= 71
now multiply your answer by 2
71×2=142
