Step-by-step explanation:
<h3>İf it is Z=(x+y)/5</h3><h3> 5Z=x+y</h3><h3> y=5Z-x </h3>
<h3>İf it is Z=x+y/5</h3><h3>then Z=(5x+y)/5</h3><h3> 5Z=5x+y</h3><h3> y=5Z-5x or 5(Z-x)</h3>
The square of the hypotenuse is equal to the sum of the square of other two sides. The value of x from the given diagram to the nearest tenth is 11.2
<h3>Pythaogram theorem</h3>
According to the theorem, the square of the hypotenuse is equal to the sum of the square of other two sides.
From the diagram
hypotenuse = 5.6 + 8.4 = 14
Other sides are x and 8.4
According to the theorem:
14^2 = x^2 + 8.4^2
x^2 = 14^2 - 8.4^2
Simplify
x^2 = 196 - 70.56
x^2 = 125.44
x = 11.2
Hence the value of x from the given diagram to the nearest tenth is 11.2

Answer:
y = 16, don't know if I'm 100% right but hope this helps.
Step-by-step explanation:
since they both equal Y they may be equal to each other
Then you would subtract 2x from both sides canceling it out on one side
2x + 8 = 5x - 4
-2x -2x
This would make the equation 8 = 3x - 4
next you add the 4 from both sides
8 = 3x - 4
+4 +4
This will leave you with 12 = 3x
now you divide 3 from both sides and 12/3 = 4 makes X = 4
next you take (4) and plug it in to one of the equations
y = 2(4) + 8
y = 8 + 8
y = 16
Answer:
C
Step-by-step explanation:
y=5x reads "y equals (5 times x)", which we can rephrase to "the value of y is 5 times the value of x"
y=x+5 reads "y equals (x plus 5)", which we can rephrase to "the value of y is 5 more than the value of x".
Ergo, answer C is what we're looking for.
Answer:
I'll take a a guess that you mean a = 18 and b = 27, but see below
Step-by-step explanation:
Remove the brackets.
-6m + 15 + 24m + 12
Collect like terms
18m + 27
Do you mean a = 18
and b = 27
Or do you mean a + b = 18 + 27 = 45?
