I solved it and i think the answer is 20 :)
Answer:
Step-by-step explanation:
Let x = the number of bottles of paint that Carmen can buy
Let y = the number of boxes of colored pencils that Carmen can buy
A bottle of paint costs $2
A box of colored pencils costs $3.50
She can spend no more than $42 on art supplies. This means
She can buy bottles of paint worth 2×x = $2x
She can buy boxes of colored pencils
worth 3.5 × y = $3.5y
Since the total amount she can spend cannot exceed $42, the equation becomes
2x + 3.5y lesser than or equal to 42
This is shown in the attached photo
b) three different solutions to the inequality would be three different possible values that x and y can take. These are
x = 7 while y = 8
x = 10 while y = 6
x = 14 and y = 4
1:Replace the variables in the theorem with the values of the known sides.
2:Square the measures, and subtract from each side
3: find the square root of each side
Answer:
30 questions
Step-by-step explanation:
60% or 0.60 x 50 questions = 30
13 + (15) = 28
Because you always add the numbers in the parenthesis so 12 + 3 = 15 and 13 + 15 = 28
