Answer:

70° and 110°

Step-by-step explanation:

Supplementary angles sum to 180°

sum the parts of the ratio, 7 + 11 = 18 parts

Divide 180° by 18 to find the value of one part of the ratio.

180° ÷ 18 = 10° ← value of 1 part, thus

7 parts = 7 × 10° = 70°

11 parts = 11 × 10° = 110°

The 2 angles are 70° and 110°

Amiraneli [1.4K]

The product of −3 1/4 and −1 1/2  as a mixed number is 4\frac{7}{8}.

The product of −3 1/4 and −1 1/2  as a simplified form is \frac{39}{8}

<h3>What is products and mixed numbers?</h3>

Thew products between two terms can be described as the multiplication operation of the the two terms to give a term which is been performed by the use of the operation sign (*) between the two terms.

The mixed number can be defined as the numbers that contains whole numbers as well as the denominators and numerator.

It should be noted that the product of −3 1/4 and −1 1/2  can be done as (-3\frac{1}{4}  * -1\frac{1}{2}  = -\frac{13}{4} * \frac{-3}{2}  = \frac{39}{8} = 4\frac{7}{8}

HELP OMG HELP IM SO STUCK
tangare [24]

Answer: -1

Step-by-step explanation:

1 - (-3) - 5 = 1 + 3 - 5

Thats because subtracting by a negative number is the same as adding the negative number's absolute value (Distance away from zero).

(1 + 3) - 5 = -1
