Answer:
see in the picture, the perimeter of this rectangle is
2( x + 3x) = 8x but the perimeter is 65.6
=> 8x = 65.6
<=> x = 65.6/8
=> x = 8.2
Answer:
Step-by-step explanation:
Your question isn't complete but let me help out based on the information given.
Joshua's recipe for chili requires 2 3/4 pounds of beef. Sondra's recipe for chili requires 2 2/3 pounds of beef.
The pounds of beef required by both of them will be:
= 2 3/4 + 2 2/3
= 2 9/12 + 2 8/12
= 4 17/12
= 4 + 1 5/12
= 5 5/12
The difference in the pounds of beef required by both of them will be:
= 2 3/4 - 2 2/3
= 2 9/12 - 2 8/12
= 1/12
Also, we.can also infer that Joshua recipe for chili requires more pounds of beef than that of Sondra
The best approximation for the solution to this system of equations is (-2.2,-3)
Option C is correct.
Step-by-step explanation:
Solving the system of equations to get the exact value of x:

Let

Putting value of y from eq(1) into eq(2)



So, Value of x is -2.2
The best approximation for the solution to this system of equations is:
x=-2.2 and y = -3
(-2.2,-3)
Option C is correct.

<span>Given:
family travelled 25 miles in 30 minutes or 50 miles /hr
current time 3.00 pm.
total distance=225 miles.
solution:
speed = distance * time
time = distance/spedd
= 225/50
time = 4.5 hours.
reaching time= 3 hours +4 hour 30 minutes= 7.30 pm</span>
Answer:
8 pounds per week
Step-by-step explanation:
AVG= total/time span
so
AVG= 128/16
AVG= 8 pounds per week
Hope this helps!
