Tiana solved the equation
-2(3x - 5) = 4(x + 3) + 8. When
she double checked her work
by substituting, it made the
equation untrue.
Answer:
actually when I solved it ,the equation is true
Step-by-step explanation:
look
-2 (3x - 5) = 4(x + 3) + 8
-6x + 10 = 4x + 12 + 8
-6x + 10 = 4x + 20
-6x - 4x = 20- 10
-10x = 10
x = -1
and when I substitute, I get 16 on both sides so I don't know where the problem is
A car rental company charges a daily rate of $31 plus $0.10 per mile for a certain car. Suppose that you rent that car for a day and your bill (before taxes) is $80. How
many miles did you drive?
Answer:
490 miles
80 - 31 = 49
.10 * 490 = 49
The number of miles you drove is 490 miles.
To find the number of miles you drove, we need to subtract the daily rate from your total bill and then divide the result by the additional cost per mile.
Let's denote the number of miles driven as 'm'.
Daily rate = $31
Additional cost per mile = $0.10
Total bill = $80
To calculate the number of miles driven:
Total bill - Daily rate = Additional cost per mile * Number of miles driven
$80 - $31 = $0.10 * m
$49 = $0.10 * m
Dividing both sides by $0.10:
$49 / $0.10 = m
490 = m
Therefore, you drove 490 miles.

This circle is centered at the origin, and the length of its radius is 2. What iS
the circle's equation?
Answer:
Step-by-step explanation:
If the center of the circle is at the origin, the general formula for the circle is
x^2 + y^2 = r^2.
Since r = 2 units in this particular problem, the equation of the circle is:
x^2 + y^2 = 2^2, or x^2 + y^2 = 4

Un estanque tiene dos laves, una de las cuáles
que salen 117 litros en 8 minulos y un desagüe que por el que salen 42 litros en 6 minutos el estanque contenía 500 litros de agua y abriendo las dos llaves al mismo tiempo y el desagüe al mismo tiempo se acabo de llenar en 48 minutos
cuál es la capacidad del estanque
Answer:
8,688 litros.
Step-by-step explanation:
Dado que un estanque tiene dos llaves, de las cuáles salen 117 litros en 8 minutos y un desagüe que por el que salen 42 litros en 6 minutos, el estanque contenía 500 litros de agua y abriendo las dos llaves y el desagüe al mismo tiempo el estanque se acabó de llenar en 48 minutos, para determinar cuál es la capacidad del estanque se deben realizar los siguientes cálculos:
6 = 42
8 = X
8 x 42 / 6 = X
336 / 6 = X
56 = X
500 + 46 x (117 + 117 - 56) = X
500 + 46 x 178 = X
500 + 8,188 = X
8,688 = X
Así, la capacidad del estanque es de 8,688 litros.

because you already know how much the roses cost for each rose and all together.
Round to nearest tenth
Answer:
Step-by-step explanation:
this is exactly the same as the 1st one, just they put it in a different orientation. sooo use law of cosines , where
QR = c
a = 12
b = 23
cos(120) = cos (P)
c = sq rt [ a^2+b^2﹣2*a*b*cos(P) ]
QR = sq rt [ 12^2 + 23^2 - 2* 12*23*cos(120) ]
QR = sq rt [ 144 + 529 - 552 * (-0.5 0 ]
QR = sq rt [ 673 + 276 ]
QR = sq rt [ 949 ]
QR = 30.8058
rounded to nearest 10th is
QR = 30.8 :)
