Answer:

No, it's not equivalent

Step-by-step explanation:

Try and solve the one with the bracket first. Expand 8(15-r) : 8x15 and 8x-r = 120 - 8r

Therefore, the equation can now be written as:

6r-r + 120-8r + 23-6

Rearrange the like terms together and solve the equation:

6r-r-8r + 120+23-6 = -3r + 137

Arc Length: The pendulum on a grandfather clock swings from side to side once every second. If the length of the pendulum is 4 f
Karolina [17]
Imagine the path of the tip of the pendulum as an arc of a circle. The circle would have a radius of 4 feet and the arc would be 20 degrees. To calculate the length of the arc, you need to find 20 degrees of the circumference. 

Length of Arc = 2*pi*R*Degree of arc/360 
Length of Arc = 2*pi*4*20/360 
Length of Arc = 8pi * 1/18 
Length of Arc = 4/9 pi feet 
<span>Length of Arc ~ 1.396263402 feet

Answer:

burrito price=$8

Taco Price=$6

Step-by-step explanation:

x=burrito price

y=taco price

3x+4y=48

solve for y

y= −3 /4 x+12

plug in

6x+2y=60

6x+2( −3 /4 x+12)=60

6x+2( −3 /4 x+12)=60

x=8

now plug in for x

3x+4y=48

3(8)+4y=48

y=6

y=6

x=8

burrito price=$8

Taco Price=$6
