Answer:
the correct answer is a. (x = 2, y = 1, z= -2).
you can try inserting each value to all three equations and you'll see that only "a" satisfies all equations.
Step-by-step explanation:
4x+4y+3z=6
4(2)+4(1)+3(-2) = 12-6 = 6
4x + 7y + 5z = 5
4(2)+7(1)+5(-2) = 15-10 = 5
5x + 3y + 3z= 7
5(2)+3(1)+3(-2) = 13-6 = 7
now, you can clearly see that all the equations are satisified with the help of the employment of the three values x=2 , y=1, and z = -2 which makes A the correct answer.
Answer:
494cm2
Step-by-step explanation:
Área = (base × height)/2
Área=(38×26)/2=988/2=494cm²
Answer: x=4
Step-by-step explanation:
Since this is a rectangle we already know that all the angles are 90, so we can do this:
46+10x+4=90
50+10x=90
10x=40
x=4
Answer:
135
Step-by-step explanation:
3^3 = 27
27 x 10 / 2
270/2

The question is incomplete, let's take an hypothetical value for the Area of the circle ;
Let the are aid the circle = x in²
Answer:
Kindly check explanation
Step-by-step explanation:
The scale factor = 5/4
The initial area of square = x in²
The area of the circle after dilation will be :
Scale factor * initial area of circle
5/4 * x in²
Area after dilation = 5/4(x) in²
Just substitute the original value of the square for X in the solution to obtain the exact answer.
