Renee has dimes and quarters in her wallet that total $1.60. She has 2 more dimes than quarters.
How many of each coin does Renee have?
Answers
Given:
Renee has dimes and quarters in her wallet that total $1.60.
She has 2 more dimes than quarters.
To find:
The number of each type of coins.
Solution:
Let x be the number of dimes and y be the number of quarters.
She has 2 more dimes than quarters. So,
[tex]x=y+2[/tex] ...(i)
We know that,
1 dime = $0.10
1 quarter = $0.25
Renee has dimes and quarters in her wallet that total $1.60. So,
[tex]0.10x+0.25y=1.60[/tex] ...(ii)
From (i) and (ii), we get
[tex]0.10(y+2)+0.25y=1.60[/tex]
[tex]0.10y+0.20+0.25y=1.60[/tex]
[tex]0.35y=1.60-0.20[/tex]
[tex]0.35y=1.40[/tex]
Divide both sides by 0.35.
[tex]y=\dfrac{1.40}{0.35}[/tex]
[tex]y=4[/tex]
Substituting [tex]y=4[/tex] in (i), we get
[tex]x=4+2[/tex]
[tex]x=6[/tex]
Therefore, the number of dimes is 6 and the number of quarters is 4.

What is the perimeter in terms of x, of the rectangle shown here (x^2+7x-9) (3x^2-2x)
Answers
Given:
Consider the dimensions of the rectangle are [tex](x^2+7x-9)[/tex] and [tex](3x^2-2x)[/tex].
To find:
The perimeter in terms of x, of the rectangle.
Solution:
Let the length of the rectangle be [tex](x^2+7x-9)[/tex] and the width of the rectangle is [tex](3x^2-2x)[/tex] units.
The perimeter of a rectangle is:
[tex]P=2(l+w)[/tex]
Where, l is the length and w is the width of the rectangle.
Substituting [tex]l=(x^2+7x-9)[/tex] and [tex]w=(3x^2-2x)[/tex] in the above formula, we get
[tex]P=2((x^2+7x-9)+(3x^2-2x))[/tex]
[tex]P=2(4x^2+5x-9)[/tex]
[tex]P=2(4x^2)+2(5x)+2(-9)[/tex]
[tex]P=8x^2+10x-18[/tex]
Therefore, the perimeter of the rectangle is [tex]8x^2+10x-18[/tex] units.

Find the unknown values of b and c in the equation y = -x² + bx + c given its vertex is (-7, -5).
Answers
Answer:
[tex] \displaystyle b = - 14[/tex]
[tex] \displaystyle c = - 54[/tex]
Step-by-step explanation:
to figure out b we can consider the following formula:
[tex] \displaystyle \frac{ - b}{2a} = h[/tex]
the form of vertex coordinate given by
[tex] \displaystyle (h,k)[/tex]
so according to the question
[tex] \displaystyle (h,k) = ( - 7, - 5)[/tex]
by order pair we obtain:
[tex] \displaystyle h = - 7, k = - 5[/tex]
now substitute the value of h and a to the formula:
[tex] \displaystyle \frac{ - b}{2(- 1)} = - 7[/tex]
simplify multiplication:
[tex] \displaystyle \frac{ - b}{ - 2} = - 7[/tex]
cross multiplication:
[tex] \displaystyle - b = 14[/tex]
divide both sides by -1:
[tex] \displaystyle b = - 14[/tex]
now we need to figure out C to do so substitute -7 for x and -5 for y which yields:
[tex] \displaystyle - {7}^{2} - 14( - 7) + c = - 5[/tex]
simplify square:
[tex] \displaystyle -49 - 14( - 7) + c = - 5[/tex]
simplify multiplication:
[tex] \displaystyle -49 + 98+ c = - 5[/tex]
simplify addition:
[tex] \displaystyle 49+ c = - 5[/tex]
cancel 49 from both sides:
[tex] \displaystyle c = - 54[/tex]
hence,
b=-14C=-54___________________________________
Problem:Find the unknown values of b and c in the equation y = -x² + bx + c given its vertex is (-7, -5).Let's Solve it!This is a problem where you want to able to ake use of tue Vertex Form in order to get the values of b and c fir the standard form of the parabola. Vertex (-7,-5) or (h,k) in the standard form. These are the x and y coordinates of the vertex. Note the standard form is:[tex]\quad\quad\quad\quad\tt{ a{x}^{2} + bx + c}[/tex]
Since we have the given of:[tex]\quad\quad\quad\quad\tt{ a \: = - 1}[/tex]
[tex]\quad\quad\quad\quad\tt{ h = - 7}[/tex]
[tex]\quad\quad\quad\quad\tt{ k \: = - 5}[/tex]
Note the vertex form is:[tex]\quad\quad\quad\quad\tt{y = a(x - h {)}^{2} } + k[/tex]
[tex]\quad\quad\quad\quad\tt{y = - 1(x - ( - 7) {)}^{2} } + ( - 5)[/tex]
[tex]\quad\quad\quad\quad\tt{y = - 1(x + 7 {)}^{2} } - 5[/tex]
[tex]\quad\quad\quad\quad\tt{ \boxed{y = - {x}^{2} - 14x - 54}}[/tex]
Hence, The answer for b and c is:[tex]\quad\quad\quad\quad\tt{ \boxed{ \boxed{ \color{magenta}{b = - 14}}}}[/tex]
[tex]\quad\quad\quad\quad\tt{ \boxed{ \boxed{ \color{magenta}{c = - 54}}}}[/tex]
Let's confirm it :You can use x coordinate of the vertex like this,[tex]\quad\quad\quad\quad\tt{ - 7 = \frac{b}{2(a)} }[/tex]
[tex]\quad\quad\quad\quad\tt{ - 7 = \frac{b}{2(-1)} }[/tex]
[tex]\quad\quad\quad\quad\tt{ - 7 = \frac{b}{-2} }[/tex]
[tex]\quad\quad\quad\quad\tt{ (- 2)( - 7) = - b }[/tex]
[tex]\quad\quad\quad\quad\tt{ \frac{ (- 2)( - 7)}{ - 1} = b }[/tex]
[tex]\quad\quad\quad\quad\tt{ \frac{ 14}{ - 1} = b }[/tex]
[tex]\quad\quad\quad\quad\tt{ \boxed{ - 14 = b }}[/tex]
You can also confirm the y coordinate of the vertex in the standard form by plugging the x coordinate.[tex]\quad\quad\quad\quad\tt{y = - {(-7)}^{2} - 14(-7) - 54}[/tex]
[tex]\quad\quad\quad\quad\tt{y = - 49 +98 - 54}[/tex]
[tex]\quad\quad\quad\quad\tt{y = - 49 +98 - 54}[/tex]
[tex]\quad\quad\quad\quad\tt{y = 49 - 54}[/tex]
[tex]\quad\quad\quad\quad\tt{ \boxed{y = - 5}}[/tex]
So, the final answer for b and c is:[tex]\quad\quad\quad\quad\tt\huge{ \boxed{ \boxed{ \color{magenta}{b = - 14}}}}[/tex]
[tex]\quad\quad\quad\quad\tt\huge{ \boxed{ \boxed{ \color{magenta}{c = - 54}}}}[/tex]

No dia da festança, bianca comprou dos pasteis por $5,20, duas maçãs do amor por $ 3,40 e dois refrigerantes por $7,60. Quanto bianca gastou?
Answers
Responder:
$ 16,2
Explicação passo a passo:
No dia da festa, Bianca comprou os pastéis por US $ 5,20, duas maçãs do amor por US $ 3,40 e dois refrigerantes por US $ 7,60. Quanto bianca você gastou?
O valor gasto por Bianca é a soma de todos os itens que ela comprou:
Pastelaria = $ 5,20
Maçãs do amor = $ 3,40
Refrigerantes = $ 7,60
A soma da soma dá o valor gasto de Bianca:
Doces + Maçãs do Amor + Refrigerante
$ (5,20 + 3,40 + 7,60)
= $ 16,2
