Answer:

its b.

Step-by-step explanation: 5n − 19 + n + 7 = 144 − 6n

6n − 12 = 144 − 6n

12n = 156

n = 13

m∠z = (144−6n)°

m∠z = (144−6×13)°

m∠z = 66°

Allison and Megan were at track practice. The track is 3/8 kilometers around.

Ad libitum [116K]

Allison ran 3/8 km (0.375 km) in 3 minutes.

Set up a proportion to find how long it takes for her to run 1 km

$\frac{0.375\textrm{km}}{3 \textrm{min}} = \frac{1\textrm{km}}{x \textrm{min}}$

Cross multiply to get:

$3 = 0.375x$

Solve:

$x = \frac{3}{0.375}$

x = 8 minutes

Can someone help me please i need to get this right

mixer [17]

Answer:

If there are 2 quarters for every 3 nickels,

then there are $45*\frac{2}{3} =30$ quarters.

If there are 2 dimes for every quarter,

then there are $30*2=60$ dimes.

If the number of pennies and nickels together are equal to the number of dimes, then there are $60-45=15$ pennies.
