Cynthia gave 15 of her toys to her little sister. If she had 25 toys, how many did she give away?
Answers
5
she gave her sister 5 toys.
Correction to the question - It is not 15 it 1/5th.
According to the given question Cynthia had 25 toys and she gave 1/5th of her toys to her little sister.
So, The total number of toys is 25 to find 1/5th of it we need to multiply the total number of toys she had and the fraction she gave.
(25 x 1/5) = 5. so the number of toys she gave away to her little sister is 5.

Determine if a relation is a function {(-1,5), (2, 7), (-3,2), (-1, 1)}
Answers
Answer:
Step-by-step explanation:
A relation is only a function if ALL the x-values (the first number in the pairs) ONLY have one partner.
Check that -1
At first that -1 is paired up with a 5 in the ordered pair (-1, 5) but then later... that -1 is down there hanging out with a 1 in the last ordered pair (-1, 1).
This means that this relation (all the pairs lumped together) is NOT a function. Just because of that -1 pairing up with more that one partner.

Jake has two dogs, Euclid and Pythagoras. Euclid is a smaller dog and Pythagoras is larger. Jake found that Pythagoras lost 13 pounds from January to June. If Pythagoras gains 1.2 times Euclid's weight, Pythagoras's weight would still be 1/4 pound less than he did in January. What is Euclid's weight? (a) Write an equation that represents the scenario. Begin by defining your variable (b) Solve the equation. Show your work. (c) What is Euclid's weight? (d) Jake adopts a third dog, Riemann. Riemann weighs exactly twice what Euclid weighs.

Answers
The weight of Euclid is 10.625 pounds, and the weight of Riemann is 21.25 pounds.
Let the current weight of Euclid = xLet the current weight of Pythagoras = TLet the January weight of Pythagoras = yThe expression that represents the given scenario is written as;
when Pythagoras lost 13 pounds: T = y - 13when Pythagoras gains 1.2 times Euclid's weight: = T + 1.2xwhen Pythagoras weight is 1/4 pound less than weight in January:
T + 1.2x + 0.25 = y
y- 13 + 1.2x + 0.25 = y
1.2x - 12.75 = 0
Euclid's weight is calculated as follows;
1.2x = 12.75
[tex]x = \frac{12.75}{1.2} \\\\x = 10.625 \ pounds[/tex]
The weight of Riemann is calculated as follows;
[tex]= 2 (10.625)\\\\= 21.25 \ pounds[/tex]

Answers
The expression can be used to determine how much more money Club A will cost than Club B after x months is 7 - 4x
A linear equation is in the form:
y = mx + b;
where y, x are variables, m is the rate of change and b is the initial value of y.
Let y represent the total cost for x months.
Club A charges a $35 joining fee, plus $19 per month. hence:
y = 19x + 35
Club B charges a $28 joining fee, plus $23 per month. hence:
y = 23x + 28
Club A will cost than Club B:
19x + 35 - (23x + 28)
= 7 - 4x
The expression can be used to determine how much more money Club A will cost than Club B after x months is 7 - 4x

Karina uses the system of equations below to compare the monthly utility costs in July and December for electricity, x, and natural gas, y. 750x + 17y = 141.61 300x + 30y = 75.90 Karina solves the system using linear combination and arrives at the equation 116y = 96.28. She then solves this equation for y. Which statement explains Karina’s solution? The cost of natural gas is $0.17 per unit. The cost of natural gas is $0.20 per unit. The cost of natural gas is $0.72 per unit. The cost of natural gas is $0.83 per unit.
Answers
The correct statement is The cost of natural gas is $0.83 per unit.
The equations representing her utility costs in July and December are known as simultaneous equations. These equations have to be solved jointly in order to determine the cost of electricity and natural gas.
Given the equation gotten by Karina: 116y = 96.28
Where y represent the cost of natural gas
In order to determine the value of y, divide both sides of the equation by 116
y = 96.28 / 116
y = $0.83

pls help. I dont really understand these problems. fraction area and perimeter
Answers
Answer:
Perimeter: 14 9/10 cm
Area: 11 7/10 cm^2
Step-by-step explanation:
First, you must find the perimeter of the rectangle. The definition of perimeter in terms of mathematics are: the continuous line forming the boundary of a closed geometric figure. To find the perimeter of any shape, you must add up all the sides. Thus:
2 1/4 + 2 1/4 + 5 1/5 + 5 1/5 = ?
To put it simpler -
2(2 1/4 + 5 1/5) =
4 5/10 + 10 4/10 =
14 9/10 cm
Then, you must find the area of the rectangle. The definition of the area are: the extent or measurement of a surface or piece of land. In other words, the amount of space an object takes up. You must multiply the length and width of the rectangle to find the area.
Formula of area:
A = L x W
A = 2 1/4 x 5 1/5
A = 9/4 x 26/5
A = 234/20
A= 11 7/10 cm^2
To sum it up, the perimeter of the rectangle is 14 9/10 cm and the area 11 7/10 cm^2.
