Adam, Beth, and Carly walked a total of 10 miles collectively. Beth walked twice as far as Adam, and she walked a half a mile fu

rther than Carly. If a = number of miles Adam walks, b = number of miles Beth walks, and c = number of miles Carly walks, which equation is NOT true for this situation?
A) b = 2a
B) b = c + 0.5
C) 3a + c = 10
D) a + 2c = 10.5

D) a+2c=10.5

Since b=c+\frac{1}{2}
a+b+c=10
a+(c+1/2)+c=10
a+2c+1/2=10
a+2c=9.5

Answer: Option 'D' is not correct.

Step-by-step explanation:

Since we have given that

Total distance walked by Adam , Beth, and Carly = 10 miles

Let number of miles Adam walks be a

Let number of miles Beth walks be b

Let number of miles Carly walks be c

According to question,

<u>Beth walked twice as far as Adam </u>

So, the equation will be

b=2a

Thus, Option 'A' is satisfied.

<u>Now, Beth walked a half a mile further than Carly.</u>

So, the equation will be

b=c+0.5

Thus, Option 'B' is correct.

Now, we substitute the first equation, then we get

a+b+c=10\\a+2a+c=10\\3a+c=10

Thus, Option 'C' is correct.

<u>The only incorrect equation is Option 'D' .</u>

Solve forj j - 263 = 243 ​
joja [24]
J = 506

J needs to be isolated so add 263 to both sides. -263 is cancelled out and 263 + 243 is 506.
Hence the answer of 506

Determine the axis of symmetry and the vertex of the given function.<br> y = 2x2 - 12x + 21
mestny [16]

Answer:

the vertex is ( 3 , 3)

Symetric axis‘s equation: x = 3

Step-by-step explanation:

Let‘s name the function ” f ”

f(x) = y = 2x² - 12x + 21

the vertex has coordinates of ( -b/2a , f(-b/2a) )

-b/2a = 12/2(2) = 12/4 = 3

f(-b/2a) = f(3) = 2(3)² - 12(3) + 21 = 3

then the vertex is ( 3 , 3)

the symetric axis has the equation :

x = -b/2a

then

Answer:

= 21.6216% decrease

Step-by-step explanation:

Calculate percentage change

from V1 = 29.6 to V2 = 23.2

(V2−V1)|V1|×100

=(23.2−29.6)|29.6|×100

=−6.429.6×100

=−0.216216×100

=−21.6216%change

=21.6216%decrease

Landry earned $2,300 over the summer and decided to invest it in an account that earns 4% annual compound interest. If Landry do
solniwko [45]

Answer:

Landry will have $5039.58

Step-by-step explanation:

compound interest formula: amount = p(1 + \frac{r}{n})^{nt}

p= principal ($2,300)

r= interest rate as a decimal (4% = 0.04)

n= number of times the principal is compounded per year (annually = once per year so 1 time per year)

t= time in years (20 years)

new equation: amount = 2300(1+\frac{0.04}{1} )^{1*20}

That equation equals $2,739.58 which you add to the principal.

$2,739.58 + $2,300 = $5039.58

hope this helps :) the equations aren't showing up right :(
