Complete Question
Joey tried to evaluate an expression. Here is his work:
= 97– 3 + (5³÷25)× 2 × 3²
= 97–3 + (125÷25 )× 2 × 9
Step 1 = 97 – 3 + 5 × 2 ×9
Step 2 = 97 – 3+ 10×9
Step 3 = 97 – 3+ 90
Step 4 = 97–93
Step 5 = 4
Step 6 = Is Joey's work correct?
Answer:
Joey's work is incorrect
The correct answer is 184
Step-by-step explanation:
Solving Joey's expression above using the BODMAS Rule
B - Bracket
O - Of
D - Division
M - Multiplication
A - Addition
S - Subtraction
= 97– 3 + (5³÷25)× 2 × 3²
= 97–3 + (125÷25 )× 2 × 9
Hence:
Step 1: Division
= 97 – 3 + 5 × 2 ×9
Step 2: Multiplication
= 97 – 3+ 10×9
Step 3: Addition
= 97 – 3+ 90
= 97+ 87
Step 4 :
= 97+ 87
Step 5 = 184
Therefore, Joey's work is INCORRECT because he made a mistake in Step 3 during the addition step. The correct answer is 184
One number is 16 more than another number. The two numbers have a sum of 120. Which system of equations could you use to find the two numbers?
A)y=x – 16
y=x + 120
B)y=x + 16
y = x + 120
C)y=x - 16
y=x – 120
D)y= x - 16
y = -x + 120
Answer: D)y= x - 16
y = -x + 120
Step-by-step explanation:
Let the two numbers be x and y
such that if one number is x , the other number y
Let x be the number which is 16 more than another number , so that it can be expressed as
x= y+16 which can also be written as
y= x - 16
Also, if the two numbers have a sum of 120, then it can be represented as
x+y=120 or
y = -x + 120
Therefore system of equations to find the two numbers are
D)y= x - 16
y = -x + 120
4. Find the value of x.
A 7
B -7
C 3
D 3.5
Answer:
l got 7 sorry if it is not the answer
Step-by-step explanation:
2x+12=5x-9 two will come to the other side n become 5x-2x=3x then 9 will go to the other side n become 12+9=21
3x=21 then divide both sides by 3
Simplify the expression.
(–5)3
A. 25
B. –125
C. 125
D. –15
B and C are out because those numbers are too high. A is out for 2 reasons. 1) 5x5 is 25, not 5x3 and 2) a negative times a positive is negative.
So the answer is D

To simplify the expression (-5)^3, we need to evaluate the exponent, which means multiplying the base (-5) by itself three times. The correct option is B. -125.
(-5)^3 = (-5) * (-5) * (-5)
Multiplying the negative numbers gives:
(-5) * (-5) * (-5) = 25 * (-5) = -125
Therefore, the simplified expression is -125.
So, when we simplify the expression (-5)^3.The correct option is B. -125.

2/r = 12/18
Answer:
r=3
Step-by-step explanation:
Divide the numbers
2/r=12/18
2/r=2/3
Multiply all terms by the same value to eliminate fraction denominators
rx2/r=rx2/3
simplify
2=2r/3
multiply all terms by the same value to eliminate fraction denominators again
3x2=3x2r/3
simplify
6=2r
divide both sides if the equation by the same term
6/2=2r/2
r=3

What is 51= 3x even mean
Answer:
Step-by-step explanation:
if you multiplied a number by 3, you would get 51. If you want to solve for x, divide on both sides of the equal sign.
51/3 = 3x/3
17=x
Answer: 17
Step-by-step explanation: X is your variable, you need to find what X equals
In this case you can divide
51/3= 17
You can plug in your result to check your work. If the equation is true, it is correct
Since 51= 3 x 17, or 3 x 17= 51, this is correct

y=x+4
2 =
Y=
Answer:
Solution :
{x,y} = {0/14261512,4}
Step-by-step explanation:
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = x + 4
// Plug this in for variable y in equation [1]
[1] 12x - 5•(x +4) = -20
[1] 7x = 0
// Solve equation [1] for the variable x
[1] 7x = 0
[1] x = 0
// By now we know this much :
x = 0
y = x+4
// Use the x value to solve for y
y = (-0/14261512)+4 = 4

The table shows a function. Is the function linear or nonlinear?
Answer:
nonlinear
Step-by-step explanation:
Hey There!
A linear function would have a straight line when graphed meaning that it would have a constant slope
This is a nonlinear function because y is not moving at a constant rate with x
16-8=8
8-2=6
It went down 8 then it went down 6
therefore it is a nonlinear function
