Answer:
27
Step-by-step explanation:
The equation is a onestep equation, so in order to find the variable, follow these steps:
d - 4 = 23
In order to isolate the variable or get the variable by itself, you need to get rid of the constants around it or the numbers without a variable. In order to do that for this equation, you'll need to do the inverse of subtracting 4, which would be adding four to both sides.
Adding 4 to positive 23 will give you the answer of 27;
d = 27
Therefore, the variable d equals 27

Answer:
4
Step-by-step explanation:
Pythagorean Theorem
a^2+b^2=c^2
C is the hyptonuse A and B are legs.
a^2+3^2=5^2
a^2+9=25
a^2=16
a= sqrt16
a=4

It should be E) none of the above because:
height = 0.5
Radius = 1
diameter = 2
Answer:
x = -5 y = -3
Step-by-step explanation:
-3x + 2y = 9
multiply the 2nd equation by 3 to set it up for elimination
3(x - 3y)= 3(4)
3x-9y = 12
so now combine both to add
-3x + 2y = 9
3x - 9y = 12
Adding both gives you
-7y = 21
divide both by -7 and you get
y = -3
and you substitute y back into equation to get x
x - 3 (-3) = 4 gives you
x + 9 = 4
x = 4 - 9
x = -5
