Answer:
<em><u>According to the calculation, Wayra mage a mistahe in step 2 where she added 13 and 6 together instead of multiplying to get 78.</u></em>
<em><u>She also make a mistake in step 2 where he subtracted 5z from 4z to get z instead of -z</u></em>
Step-by-step explanation:
Given the equation solved by Wayra expressed as;
Step 1: 13(z+6) = 4(z-3)-5z
She is find the value of z from the equation;
Step 2: Open the parenthesis using the distributive property;
13(z+6) = 4(z-3)-5z
13z + 13(6) = 4z - 4(3) - 5z
13z + 78 = 4z - 12 - 5z
Step 3: Simplify
13z + 78 = 4z - 5z - 12
13z + 78 = -z -12
Step 4: Collect the like terms;
13z + z = -12 - 78
Step 5: Simplify the result
14z = -90
Step 6: Divide both sides by 14
14z/14 = -90/14
z = 6.428

Answer:
So, cows heart best is faster than horse.
Step-by-step explanation:
Time and heartbeats are in direct proportion.
p = kx
Where p is the beats per minute and x represents time in minutes
Now, to find the value of k, substitute p = 152 and x = 4
152 = 4k
k = 152/4
k = 38
Cow: y = 65x
So, cows heart best is faster than horse
