Answer: The required value of z is 6.
Step-by-step explanation: Given that 5+2z is 3 more than 3z-4.
We are to find the value of z.
According to the given information, the equation expressing the given statement mathematically can be written and solved as follows:
5+2z=(3z−4)+3
⇒5+2z=3z−1
⇒3z−2z=5+1
⇒z=6.
Thus, the required value of z is 6.
Step-by-step explanation:
M = L + rL
a.
L = $63.80
M = $121.80
need to find r
121.80 = 63.80 + r×63.80
58 = r×63.80
r = 58/63.80 = 0.91 = 91%
b.
L = $65
M = $146.25
need to find r
146.25 = 65 + r×65
81.25 = r×65
r = 81.25/65 = 1.25 = 125%
Slope intercept form is y = mx + b, where m is the slope. 5 is greater than 2 so that’s why y = 5x + 1 has a greater slope than y = /x + 5
