Answer:
Z = 2.76
Step-by-step explanation:
Firstly you must realise that Z - 2.3 = 0.46
Therfore this means you must 2.3 to 0.46 to get Z
2.3+0.46+2.76
The answer is 4 and 5.
They are 2 positive numbers that satisfy the equation, (5)(4)=20.
If that doesn’t work try 2 and 10.
Hope this works!! :)
E(8) = 2*8 = 16. Should be no tricks.
Answer: x = -1 and y = -2
Step-by-step explanation:
You are given two expressions that have a relationship. There are two ways to solve this problem, but I will be going over the easy way. I'm assuming you know how to solve for one variable such as x? Well we can put the y varaible from the first equation in terms of x, from the second equation. Ill show you what I mean:
6x + 5(7x + 5) = -16
I replaced y in the first one in terms of x, so that we can solve just for x.
6x + 35x + 25 = -16
41x +25 = -16
41x = -41
x = -1
Now simply find y by plugging the now known x value into either equation
y = 7(-1) + 5
y = -2
69.24 because you round the three up
