You have the formula already, just plug in 30 for s (speed) and solve for d (distance).

5/2x+1/4=12 solve for x

aniked [119]

Answer:

4/5 (2x + 5) − 4 =1

4/5(2x +5) = 1 +4

4/5 (2x +5) = 5

2x + 5 = 5 / (4/5)

2x + 5 = 5 (5/4)

2x + 5 = 25/4

2x = 25/4 - 5

2x = 25/4 - 20/4

2x = 5/4

x = (5/4) / 2

x = (5/4) (1/2)

x = 5/8

x = 0.625

Answer:

YZ = 8.5

Step-by-step explanation:

Since RY is an angle bisector then the ratio of the sides of the triangle are equal to the corresponding ratio of the base, that is

$\frac{YX}{YZ}$ = $\frac{XR}{ZR}$ , substitute values

$\frac{11.9}{YZ}$ = $\frac{7}{5}$ ( cross- multiply )

7YZ = 59.5 ( divide both sides by 7 )

YZ = 8.5

What is the percent increase modeled in the function f(x)=20(1.5)^x

blagie [28]

The increase is D: 50% because the 1 in the parentheses stands for the 20 that was already there, with the .5 being the amount that’s actually being increased. 0.5 translates to 50%, so the answer is D.

ahrayia [7]

Answer: $100,000$

Step-by-step explanation:

Given :

$logx - 2 = 3$

add 2 to both sides

$log x = 5$

Therefore :

$x = 10^{5}$

$x = 100,000$
