Simplifying
8a + 12b = 92
Solving
8a + 12b = 92
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-12b' to each side of the equation.
8a + 12b + -12b = 92 + -12b
Combine like terms: 12b + -12b = 0
8a + 0 = 92 + -12b
8a = 92 + -12b
Divide each side by '8'.
a = 11.5 + -1.5b
Simplifying
a = 11.5 + -1.5b
Answer:
his rate of miles per hour would be 7.5 mph
Respuesta:
416
Explicación paso a paso:
El Área de la habitación:
Largo * ancho
Longitud = 15 pies
Ancho = 12 pies
Área de la habitación = Largo * Ancho
Área de la habitación = 15 pies * 12 pies
Área de la habitación = 180 pies²
Conversión del área de la habitación en patio²
Dividir el área en pies² por 9
180 pies² ÷ 9 = 20 yardas²
Costo de la alfombra por yarda cuadrada = 20.80
Costo total de la alfombra = 20.80 * 20 = 416
The two angles marked are congruent.
That is one pair of congruent angles. -------> A
Then the vertical angles are congruent.
That is a second pair of congruent angles. -------> A
Finally, we have the two sides marked congruent.
That is one pair of congruent sides. ------> S
Put together what we have above, and it gives us AAS.
Answer:
C. y = -4x +10
Step-by-step explanation:
Equation of a line is found by the formula y = mx +b
Where m is the slope and b is the y intercept
we see that y-intercept is given as 10, so b = 10 and we plug in the coordinate (2,2) into the equation to find the slope (m). We plug in x = 2 and y = 2. Shown below:
<em>We know the value of m to be -4 and b to be 10, thus we can write the equation as:</em>
Answer choice C is right.
