what is 60 /−3 and how do you solve
Answers
Answer:-20
Step-by-step explanation:
First divide 60 by 3 as you would regularly.
Your answer should be 20
Make sure to remember when multiplying with integers:
negative x negative = positive
positive x positive = positive
negative x positive = negative
positive x negative = negative
Make sure to remember when dividing with integers:
positive / positive = positive
negative / negative = positive
positive / negative = negative
negative / positive = negative
Because this question is a "positive / negative" your answer would be negative. Therefore your answer is -20

Melanie has a ribbon that is 18 inches long. She cut the ribbon into 3 equal pieces. Then she cut each of those pieces in half. How many small pieces of ribbon are there? how long is each pieces
Answers
Answer:
I guess there are 6 small pieces but dont know how long they are sry
Answer:
12 small piece of ribbon, each 3/2 inches long
Step-by-step explanation:
one 18" long ribbon divided into 3 equal pieces will produce three 6 inch ribbons
three 6" ribbons, each one cut in half (or divided by 2), equals 12 pieces
each one being 18/12 inches long; which reduces to 3/2
Víctor claims that when 1/6 is divided by a fraction the result will always be greater than 1/6 find an example of a fraction that supports victors claim and an example of a fraction that contradicts victors claim
Answers
Answer:
Step-by-step explanation:
Choose a random fraction less than 1. I will choose 1/4.
1/6 ÷ 1/4 = 1/6 × 4/1 = 4/6 = 2/3
2/3 > 1/6 so this example supports his claim.
Now chose a fraction greater than 1. I will choose 4/3
1/6 ÷ 4/3 = 1/6 * 3/4 = 3/24
3/24 < 1/6 so this contradicts his claim
what value is equivalent to 108-8x(5-2)-60

-1 + -28 = -29
1 + 28 = 29
2 + 14 = 16
4 + 7 = 11
7 + 4 = 11
14 + 2 = 16
28 + 1 = 29

The slope of the line is 3.
Step-by-step explanation:
Given function;
x(t) = -t² + 5t
y(t) = 3t, when t = 2
[tex]\frac{dx}{dt} = -2t + 5[/tex]
[tex]\frac{dy}{dt} = 3[/tex]
[tex]\frac{dy}{dx}= \frac{dy}{dt} \ \times \ \frac{1}{\frac{dx}{dt} } \\\\\frac{dy}{dx}= 3 \ \times \frac{1}{-2t + 5} \\\\\frac{dy}{dx}= \frac{3}{-2t + 5}[/tex]
t = 2
[tex]Then, \ \frac{dy}{dx}= \frac{3}{-2(2) + 5} \\\\\frac{dy}{dx}= \frac{3}{-4 + 5} \\\\\frac{dy}{dx}= \frac{3}{1} \\\\\frac{dy}{dx}= 3[/tex]
Therefore, the slope of the line is 3.

There are 874 pieces of candy in the piñata. There are 23 children at the party, and they all agreed to split the candy equally. How many pieces of candy will each child receive?
Answers
Answer:
38 candies.
Step-by-step explanation:
Given the following data;
Total number of candy = 874
Total number of children = 23
Since we know that they are all sharing it equally, each child would get;
Each child = 874/23
Each child = 38 candies.

The diagonals of a quadrilateral QRST intersect at P(2,3). QRST has vertices at Q(3,6) and R(-3,5). What must be the coordinates of S and T to ensure that QRST is a parallelogram?
Answers
Answer:
S (1 , 0)
T (7 , 1)
Step-by-step explanation:
If QRST is a parallelogram, P is the mid point of segment QS and segment RT.
Basic formula for mid-point of segment: ((x1+x2)/2 , (y1+y2)/2)
T (x₁ , y₁) S (x₂ , y₂) P (2 , 3) Q (3 , 6) R (-3 , 5)
2 = (x₁ + (-3))/2 x₁ = 7
3 = (y₁ + 5)/2 y₁ = 1
T (7 , 1)
2 = (x₂ + 3))/2 x₂ = 1
3 = (y₂ + 6)/2 y₂ = 0
S (1 , 0)
