Answer: 36 cents

Step-by-step explanation: Unit price means the cost per unit which in this case is the cost per pound of sugar.

Since we know that it costs $2.50 for 7 pounds of sugar, to find the cost for 1 pound of sugar, we need to divide 7 into $2.50 or just 2.50 ÷ 7.

2.50 ÷ 7 = 0.357142857 which we can round up to 36 cents.

Therefore, the unit price is 36 cents per pound of sugar.

one angle has a measure that is less than 15 than two times a number. a second angle is three times the number. the angles are c
adell [148]

Answer:

27 degrees and 63 degrees

Step-by-step explanation:

Let n be the number.

Angle 1: 2n-15

Angle 2: 3n

If the angles are complementary they add up to 90.

Therefore we can write an equation.

2n-15+3n=90

Combine like terms

5n-15=90

Add 15 to both sides

5n=105

n=21

Now we plug 21 in for n and solve for the angles

Angle 1 = 2(21)-15

Angle 1 = 42-15

Angle 1 = 27

Angle 2 = 3(21)

Angle 2 = 63
