Answer:
w = -8
Step-by-step explanation:
step 1:(20 - 9w) - 4 • (15 - w) = 0
step 2: -5w - 40 = -5 • (w + 8)
step 3: -5 • (w + 8) = 0
step 4: Subtract 8 from both sides of the equation :
w = -8
Answer:
It’s D
Step-by-step explanation:
Because you have two sides that are congruent and an angle giving you SAS
The graph of the piecewise function includes
(1) a straight line passing through point (-3, 0) and stopping at point (0, 3) with an unshaded small circle at the end of point (0, 3) and an arrow at the other end.
(2) a shaded small circle at point (0, 5), and
(3) a straight line starting at the point (0, -1) and passing through the point (2, 3) with an unshaded small circle at the point (0, -1) and an arrow at the other end.
Answer:
30
Step-by-step explanation:
We require to calculate the volume of 1 brick
V = lbh ( l is length, b is breadth and h is height ), that is
V = 14 × 8 × 5 = 560 cm³
Now divide the volume of concrete available by the volume of 1 brick.
number of bricks made = 
= 30
