A sidewalk is built 12 bricks wide by laying each brick side by side.how many inches wide is this sidewalk is each brick measure

Fofino [41]

Answer:

The sidewalk is 34.5 inches wide.

Step-by-step explanation:

Given:

A sidewalk is built 12 bricks wide by laying each brick side by side.

Brick measures 2 7/8 inches wide.

Now, to find the width of sidewalk.

<em>Width of brick = 2 7/8 = 23/8.</em>

<em>Number of bricks = 12.</em>

So, the sidewalk = width of brick × number of bricks

= $\frac{23}{8} \times 12$

= $\frac{276}{8}$

= $34.5\ inches$

Therefore, the sidewalk is 34.5 inches wide.

What is the equation, in point-slope form, for a line that goes through (2, −6) and has a slope of −3\4 ?

s344n2d4d5 [400]

Y - y1 = m(x - x1)
slope(m) = -3/4
(2,-6)...x1 = 2 and y1 = -6
now we sub...pay close attention to ur signs
y - (-6) = -3/4(x - 2)...not done yet
y + 6 = -3/4(x - 2) <===
