Answer:
36 pencils
Step-by-step explanation:
Let h and p represent the number of highlighters and the number of pencils, respectively.
Then h + p = 45, and h = 45 - p.
Tom paid a total of $30 for these supplies, with ($2/highligher)(h) + ($0.333/pencil) adding up to that amount.
substituting 45 - p for h in 2h + 0.333p = 30, we get:
2(45 - p) + 0.333p = 30, or
90 - 2p + 0.333p = 30
Combine the constants: 60 = 2p - 0.333p, or 60 = 1.667p
Then p = 60/1.667 = 35.9928, or 36.
Tom bought 36 pencils for $12, and 45-36, or 9, highlighters for $18, for a total purchase of $30. This shows that these calculations are correct.
no it is not one x cannot have 2 y's.
It would be 5x?=60 because to find "?" you would need to divide 60 and 5. Since Hector earned 5 times what he did last week it would be modeled by 5 times "?"
Answer:
The answer to your question is: (2a + 2b)²
Step-by-step explanation:
a² + b² = z
ab = y
Which is equivalent to 4z + 8y ?
Substitution
4(a² + b²) + 8(ab)
Simplify 4a² + 4b² + 8ab
Order 4a² + 8ab + 4b² It's a perfect square trynomial
Factorize (2a + 2b)²
Answer:
The answer is -15/20, -1/4, 7. Thanks
