Answer:
5
Step-by-step explanation:
perpendicular slopes multiply to -1
lets say m is the missing slope
-1/5*m=-1 so m=5
Answer:
B
Step-by-step explanation:
A=b×h
A=12×10
A=120
The anwser is 120 sq centimeters
Bricklayer Ben placed a total of 462 bricks.
<h3>How to use equation to find the number of bricks placed?</h3>
Bricklayer Ben places 42 bricks per hour.
Bricklayer Bob places 36 bricks per hour.
Let
x = number of hours worked by Bricklayer Bob
y = number of hours worked by Bricklayer Ben
Therefore,
x = 2y
42y + 36x = 1254
42y + 36(2y) = 1254
42y + 72y = 1254
114y = 1254
y = 1254 / 114
y = 11
Hence, Bricklayer Ben placed a total of 42 × 11 = 462 bricks.
