8 mi. 133 yd. 2 ft. - 5mi. 107 yd. 2 ft.
= (8 mi. - 5 mi.) + (133 yd. - 107 yd) + (2 ft. - 2ft.)
= 3 mi. +26 yd.
<h3>= 3 mi. 26 yd.</h3>
10 years. Bill is 25, his sister is 5, and their mother is 60.
Answer:
Surface area of square pyramid shown in picture:
A = area of 4 triangles + area of square
= 4 x 4 x 3 x (1/2) + 3 x 3
= 33 (ft)
=> Option 4 (last one) is correct
Hope this helps!

Answer:
y=-4x+3
Step-by-step explanation:
it does not show the equations that are following
but the main thing you need to know is that when two lines are parallel they have the same slope
and do you mean 2x+8y=18 not x?
edit:
answer choices: y=-4x+3, y=8x-2, y=4x+7, y=-8x+9
2y+8x=18
first change that equation to slope intercept form to find the slope
2y = -8x+18 -> y = -4x+9
slope is -4
so the answer is y=-4x+3 because it also has a slope of -4
-4 = y + 3
y = -4x - 3
Solve for Y in the first equation:
-4 = y +3
Subtract 3 from both sides:
y = -7
Now using the addition method:
rewrite the second equation as 4x+y = -3
Multiply y = -7 by - 1 to get -y = 7
Now add the two together:
4x +y = -3
-y =7
4x = 4
Divide each side by 4:
x = 4/4 = 1
Then replace x in one of the equations to solve for y which is -7
X = 1, Y = -7
