Answer:

x = -0.5

Step-by-step explanation:

From your last step:

6.8x + 9.3 = -2.6 - 17x

We have two terms with x in them on different sides of the equation, so we want to bring the 'x terms' over to the same side.

Add 17x to both sides of the equation.

6.8x + 17x + 9.3 = -2.6

Collect like terms

23.8x + 9.3 = -2.6

Subtract 9.3 from both sides

23.8x = -2.6 - 9.3

23.8x = -11.9

Divide both sides by 23.8

x = -0.5

Step-by-step explanation:

h=hotdog b=hamburger

7h+4b=13

4h+7b=14.5

(7h+4b=13)-4b

4h+7b=14.5

h=-0.57b+1.86

4h+7b=14.5

Expand the following:<br> a) 3(x + 5)<br> b) 4(x-4)<br> c) 2(5x + 1)<br> d) 7(x-9y)

Tema [17]

Answer:

solution,

$a. \: 3(x + 5) \\ \: \: = 3 \times x + 3 \times 5 \\ \: \: = 3x + 15$

$b. \: 4(x - 4) \\ \: \: = 4 \times x - 4 \times 4 \\ \: \: = 4x - 16$

$c. \: 2(5x + 1) \\ \: = 2 \times 5x + 2 \times 1 \\ \: \: = 10x + 2$

$d . \: 7(x - 9y) \\ \: = 7 \times x - 7 \times 9y \\ \: \: = 7x - 63y$

Hope this helps..

Use the diagram to find the height of statue.round to the nearest tenth

jeyben [28]

Answer:

7.3 ft

Step-by-step explanation:

The information given represents a right angle triangle with the following:

reference angle = 52°

Adjacent side length = 5.7 ft.

Opposite side length = height of the statue = h

Applying the trigonometric ratio formula, we would have:

$tan(52) = \frac{h}{5.7}$

Multiply both sides by 5.7

$tan(52) \times 5.7 = \frac{h}{5.7} \times 5.7$

$tan(52) \times 5.7 = h$

$h = 7.3 ft$ (nearest tenth)
