<h3>
Answer: A) 30</h3>
===========================================
Work Shown:
SM/MK = RM/ML
33/44 = x/40
3/4 = x/40
3*40 = 4*x ... cross multiply
120 = 4x
4x = 120
x = 120/4
x = 30
RM = 30
Answer:
Step-by-step explanation:
On the left-hand side of the equation, both terms have a common factor of , so we can pull that out:
We can now create two equations from this to solve for :
The first equation doesn't need any further work, but the second equation can be reduced by substracting from both sides to get by itself on the left-hand side:
Therefore, the two solutions to the problem are
Answer:
10.5 cm
Step-by-step explanation:
12÷9= 1.3 (1dp)
14÷(12÷9)= 10.5cm
Use the Point-Slope formula: y - y1 = m(x - x1)
-1 = m, x1 = 0, y1 = 5 y - 5 = -1(x - 0)
Distribute the (-1): y - 5 = -x
Add 5 to both sides: y = -x + 5
