Answer:
Kindly check explanation
Step-by-step explanation:
Given the question:
Find the error in the student's calculation. 2 cubed (2 minus 4) + 5 (3 minus 8). 2 cubed (negative 2) + 5 (5). 8 (negative 2) + 25. Negative 16 + 25. 9.
The student's error occurred here :
2 cubed (negative 2) + 5 (5)
(3 - 8) will give - 5 and not 5 as Witten by the student. The correct working is stated below :
2³(2 - 4) + 5(3 - 8)
Step 1:
8(-2) + 5(-5)
Step 2:
-16 + - 25
Step 3:
-41
Answer:
The answer is C
Step-by-step explanation:
So to begin, substitute all of the variables in for their corresponding value.
X=3
Y=-5
Z=-1
2XY+6YZ^2
2(3)(-5)+6(-5)(-1^2)
-30+-30
-60
Hopefully this is what they're asking for!
Answer:
4 and 6
Step-by-step explanation:
Let the smaller number be x
The bigger number be y
Eight times the smaller of two numbers plus two times the larger number is 44.
8x+2y=44
Three times the smaller number minus two times the larger number is zero
3x-2y=0
8x+2y=44
3x-2y=0
Using elimination method
Add both sides
8x+3x+2y+(-2y)= 44+0
11x= 44
x=44/11=4
Put x = 4 back in one of the equation
3x-2y=0
3(4)-2y=0
12-2y=0
Add 2y to both sides
12 = 2y
Divide both sides by 2
12/2 =y = 6
The smaller number (x) is 4 and the larger number (y) is 6
I believe x = 3 because it’s base times height & if you were to multiply 8 by 3 it’d give you 24.
