Answer:
see below
Step-by-step explanation:
24 - 3 x = -27
Subtract 24 from each side
24-24 - 3 x = -27-24
-3x =-51
Divide each side by -3
-3x/-3 = -51/-3
x = 17
Check
24 -3(17) = -27
24 -51 = -27
-27 = -27
Reduce the expression, if possible, by canceling the common factors.

Answer:
C. 0.6625 square inches
Step-by-step explanation:
To get the area of the net of a square pyramid;
We need to find the are of the square base and the area of the four triangles;
Area of the square base = s²
= (0.25 in)²
= 0.0625 in²
Area of one triangle = 0.5 × b × h
= 0.5 × 0.25 in × 1.2 in
= 0.15 in²
Area of the four triangles = 0.15 in² × 4
= 0.6 in²
Therefore;
Area of the net square pyramid = 0.0625 in² + 0.6 in²
= 0.6625 square inches
Answer:
-2x
Step-by-step explanation:
four X's minus 6 X's leaves the absence of 2 X's
x x x x
- x x x x x x
_________
- x x
The solution for this problem is:
<span>Let time taken by Emily be x </span>
<span>
then Aileen take 2/3 of x = 2x/3 </span>
<span>
1 min work of Emily = 1/x</span>
<span>
1 min work of Aileen = 1/ 2x/3 => 3/2x</span>
<span>
1 min work of both = 1/45</span>
<span>
1/x + 3/2x = 1/45</span>
<span>
5/2x = 1/45</span>
<span>
1/x = 2/225</span>
<span>
Emily take 225/2 mins to complete the work, then Aileen</span>
<span>= 225/2*2/3</span>
<span>= 75 mins.</span>
