Answer:

x = 6

Step-by-step explanation:

∠ AFB and ∠ EFC are vertically opposite angles and are congruent , then

21x - 9 = 117 ( add 9 to both sides )

21x = 126 ( divide both sides by 21 )

x = 6

William runs 5 meters in 20 steps. How many kilometers will he run if he takes 1,000 steps ?
kap26 [50]
This means 5 meters/20 steps = x/1,000 steps. 20 times 50 is 1,000, so 5 times 50 is 250 meters. 5/20 can be also reduced to 1/4 = x/1000. Use cross products rule to get 4x = 1,000. Divided both sides by 4 to get x = 250 meters.

Solve: 3^x+1 + 3^x= 108​
mash [69]

Answer:

x = 3

Step-by-step explanation:

{3}^{(x + 1)}  +  {3}^{x}  = 108 \\  \\  {3}^{x} .3 +  {3}^{x}  = 108 \\  \\  {3}^{x} (3 + 1) = 108 \\  \\  {3}^{x} (4 )= 108 \\  \\  {3}^{x}  =  \frac{108}{4}  \\  \\  {3}^{x}  = 27 \\  \\  {3}^{x}  =  {3}^{3}  \\  \\ \implies x = 3

Jasmine purchased a laptop worth $1,500 in 2007. It loses its value by %32 each year. What is the value of the laptop in 2010? R
Lunna [17]

Answer:

$471.65

Step-by-step explanation:

-The value of the laptop after each year is calculated by the formula:

P_t=P_o(1-d)^t

where:

P_t is the value at time t

P_o is the initial value

d is the rate of depreciation

t is the time

#We substitute the values to solve for the value after 3 years(2010-2007=3):

P_t=P_o(1-d)^t\\\\=1500(1-0.32)^3\\\\=\$471.65

Hence, the value of the laptop in 2010 is $471.65
