Help me please number 7 (please show work)
astra-53 [7]

Answer:

m<H=30 degrees by the Triangle Sum Theorem, so <H=<V. <G=<U, they are right angles. If GH=UV, triangle FGH=triangle TUV by the ASA.

x=3  and y=8

Step-by-step explanation:

H equals 30 by 180-150=30 (getting 150 by adding 60 and 90)

I know this is not much of a answer, but I hope it helps a little.

3x/2y=11 x+y/2=7 igualacion<br> Alguien me puede ayudar
bearhunter [10]

La solución del sistema de ecuaciones es igual a (x, y) = (308/47, 42/47).

<h3>¿Cómo resolver un sistema de ecuaciones linear por igualación?</h3>

Los sistemas de ecuaciones basadas en entidades algebraicas se resuelven mediante procedimientos algebraicos. Grosso modo, el método de resolución por igualación consiste en despejar una variable en dos ecuaciones del sistema para eliminarla y reducir el número de ecuaciones <em>lineales</em> y el número de variables.

A continuación, presentamos una aplicación del método de eliminación:

\frac{3\cdot x}{2\cdot y} = 11

x = \frac{22\cdot y}{3}

x + \frac{y}{2} = 7

x = 7 - \frac{y}{2}

\frac{22\cdot y}{3} = 7 - \frac{y}{2}

\frac{47\cdot y}{6} = 7

y = 42/47

x = 7 - \frac{y}{2}

x = 308/47

La solución del sistema de ecuaciones es igual a (x, y) = (308/47, 42/47).

Simplify -2x+7=15, i need help understanding why it is -4
yulyashka [42]

Answer:

Step-by-step explanation:

Step 1: Subtract 7 from both sides.

−2x+7−7=15−7

−2x=8

Step 2: Divide both sides by -2.

−2x

−2

=

8

−2

x=−4

a) The average height of sunflowers in a field is 64 inches with a standard deviation of 3.5 inches. Describe a normal curve for
tresset_1 [31]
The values on the horizontal axis are:
at 0 = 64
at one standard deviation (lower, upper) = (60.5 , 67.5)
at two standard deviation (lower, upper) = (57 , 71)
at three standard deviation (lower, upper) = (53.5 , 74,5)

B. P(x > 71) = 1 - P(x < 71) = 1 - P[z < (71 - 64)/3.5] = 1 - P(z < 2) = 1 - 0.97725 = 0.02275
Therefore the no of plants taller than 71 inches will be approximately 0.02275 * 3000 = 68
