Answer:

50° and 40°

Step-by-step explanation:

Complementary angles sum to 90°

sum the parts of the ratio, 5 + 5 = 9 parts

divide 90 by 9 for the value of one part of the ratio

90° ÷ 9 = 10° ← value of 1 part of the ratio, thus

5 parts = 5 × 10° = 50°

4 parts = 4 × 10° = 40°

The 2 angles are 50° and 40°

Answer: -3

Step-by-step explanation:

The rate of change in a graph is the same as the slope. To find the slope, divide the change in y by the change in x. In this case, it's -9/3, which gets you -3.

Which expression can be added to the right side of the equal sign form an equation? 8•7 - 4=
photoshop1234 [79]
You use the order of operations. So in you start with multiplication. 8*7= 56. Then that would leave 56-4. 56-4 is 52.

Ecuación 2:<br> 10x + 20y = 8000<br> ayudaaa
Elenna [48]

Answer:

y = 300

x = 200

Step-by-step explanation:

Esta pregunta parece incompleta, parece que acá tenemos un sistema de ecuaciones:

x + y = 500

10*x + 20*y = 8000

Estas ecuaciones tienen que resolverse en conjunto, y de acá sacaremos un par de puntos (x, y) que son solución para ambas ecuaciones.

El primer paso para resolver esto es aislar una variable en una de las ecuaciones, en este caso podemos aislar x en la primera ecuación y así obtener:

x = 500 - y.

Ahora podemos reemplazar eso en la segunda ecuación y obtener:

10*(500 - y) + 20*y = 8000.

Ahora resolvemos esto para y.

5000 - 10*y + 20*y = 8000

10*y = 8000 - 5000 = 3000

y = 3000/10 = 300.

Y sabíamos que:

x = 500 - y = 500 - 300 = 200

Entonces la solución es:

y = 300

x = 200

Help please i suck at geometry
Tems11 [23]

Answer:

A

Step-by-step explanation:

10 and 8 are equal

11 and 15 are equal

due to the fact that the angles 10 and 11 but also 8 and 15 are supplementary, we know that they add up to be 180 degrees

180-42=138 degrees

and this means that angle 8 will also be 138 because of what we established earlier
