What value of p would make the equation to
12?
Answers
Answer:
p=10
Step-by-step explanation:
q = 4 +0.8p
Let q = 12
12 = 4 +0.8p
Subtract 4 from each side
12-4 = 4+.8p -4
8 = .8p
Divide each side by .8
8/.8 = .8p/.8

Answer:
(x, y) = (9, 17)
Step-by-step explanation:
Any two pairs of equations can be used to form a system of equations that will give appropriate values of x and y. Let's set the upper and lower left expressions equal to the middle one.
2x +3y -20 = 4x +5y -72 . . . . upper left = middle
52 = 2x +2y . . . . . . . . add 72-2x-3y
x + y = 26 . . . . . . . . . . divide by 2
and ...
5x -2y +38 = 4x +5y -72 . . . . lower left = middle
110 = -x +7y . . . . . . . . . . . . . add 72-5x+2y
Now we have two equations in two unknowns that will give us the common values of x and y. Adding these equations eliminates x and gives the value of y:
(x +y) +(-x +7y) = (26) +(110)
8y = 136 . . . . . . . . simplify
y = 17 . . . . . . . . . divide by 8
x = 26 -y = 26 -17 = 9
The values of x and y that make all of these expressions equal are ...
(x, y) = (9, 17)
The value they are equal to is ...
2x +3y -20 = 2(9) +3(17) -20 = 18 +51 -20 = 49
__
Check
upper right = 9 -4(17) +108 = 9 -68 +108 = 49
lower right = 3(9) -17 +39 = 27 -17 +39 = 49

A triangle has angle measurements of 66°, 66°, and 48°. Is this triangle isosceles?
Answers
Answer:
yes
Step-by-step explanation:
The 2 base angles of an isosceles triangle are congruent.
66° + 66° + 48° = 180° ( sum of angles in a triangle )
Thus the triangle is isosceles with base angles = 66° and vertex = 48°

im having trouble solving this. y=5(x-3)
Answers
Hi there!!
If you need X to be solved then the answer is X=Y over 5+3 and if your looking for the answer for Y then the answer is Y=5x−15
When you are solving for X you will need to use the distributive property so you can multiply 5 by X-3.
Y=5x-15. Once you've done that then you need to swap sides so all of the variables are on the same side as each other (they need to be on the left side) 5x-15=Y.
Then you need to add 15 to both of the sides to make it look like this ->5x=Y+15
When that's done you then need to divide both sides by 5 so it then looks like this when done.
5x over 5= Y+15 over 5
When you divide this by 5, it then undoes the multiplication by 5.
X= Y+15 over 5
Finally, you need to divide Y+15 by 5
X=Y over 5 plus 3
When solving for Y, all you will need to do is use the distributive property to multiply 5 by X-3.

Amy is trying to determine how many different outfits she can make. She has 4 bottoms 7 tops, 2 belts, and 5 pairs of shoes. Assuming she wears one of each item, how many different outfits can
she make?
Answers
Answer:
Amy puede hacer 4 conjuntos.
Step-by-step explanation:
La solución sería
Se sabe que un conjunto de vestir se compone de camisa o blusa, pantalones, zapatos y cinturones, aunque este ultimo es opcional.
Lo que haremos es esto, empezamos a coger una pieza de cada prenda para armar un conjunto.
Primer conjunto:
1 blusa, 1 pantalón, 1 cinturón, y 1 par de zapatos.
Y esto quedaría así: 3 pantalones, 6 blusas, 1 cinturón y 4 pares de zapatos.
Segundo conjunto:
1 blusa, 1 pantalón, 1 cinturón y 1 par de zapatos.
Esto quedaría así: 2 pantalones, 5 blusas, 0 cinturones, 3 pares de zapatos. Sabemos que el cinturón es opcional, así que podemos continuar.
Tercer conjunto:
1 blusa, 1 pantalón y un par de zapatos.
Esto quedaría así: 1 pantalón, 4 blusas, 0 cinturones y 3 pares de zapatos.
Cuarto conjunto:
1 blusa, 1 pantalón y un par de zapatos.
Esto quedaría así: 0 pantalones, 3 blusas, 0 cinturones y 2 pares de zapatos. Como en un conjunto el pantalón es prioridad, al no tener más pantalones los conjuntos quedarían hasta aquí.
¡Recuerda!
No es lo mismo organizar tu ropa en conjuntos, a que hagas variaciones con ella.
