Answer:

109 17/20

Step-by-step explanation:

The distance is given as 2197 miles long at a speed of 20 miles per day. Speed is defined as distance over time:

V=d/t

We can calculate t because we have V and d:

20=2197/t

t=2197/20[tex][tex]t=109.85

109.85 in a mixed number is 109 85/100. We can divide the fraction by 5 we get 109 17/10.

Answer:

x²+8x+16

Step-by-step explanation:

f(x) = (x+4)²

= (x+4)(x+4)

= x² + 4x + 4x + 16

= x² + 8x + 16

T=p(0.09)2/3, where p is the original amount in the account, if the original account amount was $2570, what is her current balan
DanielleElmas [232]

The current balance amount is $154.20

Step-by-step explanation:

Given,

T = p(0.09)\frac{2}{3}

Where;

p represents the original amount in the account.

Given original amount in the account = $2570

Putting p=2570

T=2570(0.09)\frac{2}{3}\\\\T=\frac{462.6}{3}\\\\T=154.2

The current balance amount is $154.20

Solve for m.<br> 12.6+4m=9.6+8m12.6+4m=9.6+8m
vampirchik [111]

Answer:

m = 3/4

Step-by-step explanation:

12.6+4m=9.6+8m

Isolate the variable, m. Note the equal sign, what you do to one side, you do to the other.

Subtract 4m and 9.6 from both sides:

12.6 (-9.6) + 4m (-4m) = 9.6 (-9.6) + 8m (-4m)

12.6 - 9.6 = 8m - 4m

Simplify:

12.6 - 9.6 = 8m - 4m

3 = 4m

Isolate the variable, m. Divide 4 from both sides:

4m = 3

(4m)/4 = (3)/4

m = 3/4

3/4 is your answer for m.
