Answer:

A bagel costs $1.55, so that would be 155 cents

Step-by-step explanation:

Given Info:

x = cost of a piece of toast

y = cost of a bagel

z = cost of a muffin

2x + y = 3.15

y + z  = 3.30

x + 2y + 3z = 9.15

Calculations:

2x + y - (y + z ) = 3.15 - 3.30

2x - z = -0.15

-z = -0.15-2x

z = 0.15+2x

y = 3.15 - 2x

x + 2y + 3z = 9.15

x + 2(3.15 - 2x) + 3(0.15 + 2x) = 9.15

x + 6.3 -4x + 0.45 + 6x = 9.15

3x + 6.75 = 9.15

3x = 2.4

x = 0.80 cents per piece of toast

2x + y = 3.15

2(0.80) + y = 3.15

1.60 + y = 3.15

y = 1.55

So a bagel costs $1.55

The cup, on the 9th hole of a golf course, is located, dead center, in the middle of a circular green, which is 35 feet in radiu
ale4655 [162]

Answer:

± 27.33 ft

Step-by-step explanation:

For the given problem, we can estimate the initial and final coordinates of the line of the ball path as (-40,-50) and (0,0). Therefore, the slope is:

(-50-0)/(-40-0) = 50/40 = 1.25

Similarly, we can estimate the slope of a perpendicular line to the line of the ball path as: -1*(1/1.25) = -0.8.

Therefore, using (0,0) and the slope -0.8, the equation of the perpendicular line is: -0.8 = (y-0)/(x-0);

-0.8 = y/x

y = -0.8x

Furthermore, we are given the circle radius as 35 ft and we can use the distance formula to find the two points 35 ft far from the origin:

35^2 = x^2 + y^2

y = -0.8x

35^2 = x^2 + (-0.8x)^2

1225 = (x^2 + 0.64x^2)

1225 = 1.64x^2

x^2 = 1225/1.64 = 746.95

x = sqrt(746.95) = ± 27.33 ft

Four more than twice a number<br><br>a.2x+4<br><br><br>b.4x+2<br><br>c.6x<br><br>d.2x &gt; 4​
makkiz [27]

Answer:

a. 2x + 4

Step-by-step explanation:

Four more than twice a number

Let x = unknown number

Four more than twice of x

Twice of x can be written as 2x

Four more than 2x

Four more can be written as + 4

We get 2x + 4

Is this true or false 276 times 13 = 276 times 7 + 276 times 6 = 1,932 + 1,656 and why?
DIA [1.3K]

Answer:

Step-by-step explanation:

13 = 6+7

276*13 = 276*(7+6)

           = 276*7 + 276 *6      {distributive property upod addition}

           = 1932 + 1656

          = 3588
