Answer:

x = - 8

Step-by-step explanation:

4x - 9 + 3x = 8x - 1

7x - 9 = 8x - 1

7x - 8x - 9 = 8x - 8x - 1

- x - 9 = - 1

- x - 9 + 9 = - 1 + 9

- x = 8

- x ÷ - 1 = 8 ÷ - 1

x = - 8

1) 2x11 = I don’t know how to do this

Fynjy0 [20]

Answer:

22, Twenty Two

Step-by-step explanation:

A good way to look at multiplying 11 is that the number, if it’s under 10, will then be two of that number. For instance, 4 x 11 = 44, 6 x 11 = 66, and so on and so forth.

3. A kite is aloft at the end of a 1500 foot string. The string make an angle of 43° with the

sineoko [7]

Answer:

$h= 1500\,*\,sin(43^o)$

Step-by-step explanation:

Notice that there is a right angle triangle formed with sides as follows:

hypotenuse is the actual 1500 ft string. The acute angle 43 degrees is opposite to the segment that represents the height of the kite from the ground. Therefore, the trigonometric ratio that we can use to find that opposite side to the given angle, is the sine function as shown below:

$sin(43^o) = \frac{opposite}{hypotenuse} \\sin(43^o) = \frac{opposite}{1500}\\opposite = 1500\,*\,sin(43^o)\\h= 1500\,*\,sin(43^o)$

Is 30/12 and 40/16 equivalent?

vlabodo [156]

$We\ pull\ the\ whole\ numbers\ from\ fractions:\\\\ \frac{30}{12}=2\frac{6}{12}=2\frac{1}{2}\\\\
\frac{40}{16}=2 \frac{8}{16}=2\frac{1}{2}\\\\\
\frac{30}{12}=\frac{40}{16}\\\\They\ are\ equivalent.$
