Answer:4

Step-by-step explanation:

distribute -3 to both terms and you get -6x+9=-15. next you’ll subtract -15 by 9 and get -24. the equation is now -6x=-24. the final step is to divide -24 by -6 and you’ll get 4

Answer:

Total volume of the figure = 1067 cm³

Step-by-step explanation:

Volume of the composite figure = Volume of the rectangular prism + Volume of the square pyramid

Volume of the rectangular prism = Length × Width × Height

= 10 × 10 × 7

= 700 cm³

Volume of the square pyramid = $\frac{1}{3}(\text{Area of the base})\times (\text{height})$

= $\frac{1}{3}(\text{Side})^2$ × height

= $\frac{1}{3}(10)^2(18-7)$

= 366.67 cm³

Total volume of the composite figure = 700 + 366.67 = 1066.67 cm³

≈ 1067 cm³

CAE it is 65˚

CBD it is 65˚

Step-by-step explanation:

x+40=3x-10

Move the 3x to the other side by subtracting by 3x on both sides

x-3x+40=3x-3x-10

The equation now looks like this:

-2x+40=-10

Move 40 to the other side by subtracting 40 both sides:

-2x+40-40=-10-40

-2x=-50

Divide by -2 on both sides:

-2x/-2=-50/-2

x=25

Since we found out what x is we can replace x in both CAE and CBD:

For CBD: 25+40 is 65

For CAE: 3(25)-10 is 65
