Solve the equation. -9x + 1 = -x + 17

ddd [48]

Answer:

The value of $x$ :

$x = -2$

Step-by-step explanation:

Find the value of $x$ :

$-9x + 1 = -x + 17$

-Add both sides by $x$ :

$-9x + 1 + x = -x + x + 17$

$-8x + 1 = 17$

-Subtract both sides by $1$ :

$-8x + 1 - 1 = 17 - 1$

$-8x = 16$

Divide both sides by $-8$ :

$\frac{-8x}{-8} = \frac{16}{-8}$

$x = -2$

So, the final answer would be $x = -2$ .

Answer:

golf: $10
batting: $2.50

Step-by-step explanation:

We can write two equations in the two unknowns using the given relations. Let g and b represent the costs of a round of golf and a turn in the batting cage, respectively.

5g +4b = 60 . . . . . Sylvester's expense

3g +6b = 45 . . . . . Lin's expense

Dividing the second equation by 3 gives ...

g +2b = 15 ⇒ 2b = 15 -g

Substituting into the first equation, we have ...

5g +2(2b) = 60

5g +2(15 -g) = 60 . . . . . substitute for 2b

3g = 30 . . . . . . . . . subtract 30, collect terms

g = 10 . . . . . . . divide by 3

2b = 15 -10 = 5 . . . . use the value of g to find b

b = 2.5 . . . . . . . . divide by 2

Mini golf costs $10 per round; batting cages cost $2.50 per turn.

Answer:

See explanation

Step-by-step explanation:

1st photo:

x = $\sqrt{15}$

$\frac{x}{5} = \frac{3}{x}$

$x^{2}$ = 15

x = $\sqrt{15}$

2nd photo:

(a) GEH ~ FGH ~ FEG

similar triangles, use similar corners in the right order

(b) $\frac{FE}{GE} = \frac{GE}{EH}$ AND $\frac{FH}{GH} = \frac{GH}{HE}$

similar triangles, use similar sides in proportion

3rd photo:

x = 4.5 or 4 1/2

$\frac{x}{3} = \frac{3}{2}$

2x = 9

x = 4.5 or 4 1/2

4th photo:

Length of string = 118.2 ft

sin(40) = 76/x

x = 76/sin(40) = 118.2
