Answer: two equations represent the situation are
y = 3x and y = x + 4
Step-by-step explanation:
The smaller number was represented by x and its values on the x coordinate.
The larger number was represented by y and its values on the y coordinate.
The larger number is equal to 3 times a smaller number. This means that
y = 3x
Also, the sum of the smaller number and 4 is the larger number. This means that
y = x + 4
Answer:
that is step 1 and step 2 and step3
step 4
Let's solve your equation step-by-step.
−4(x+2)=8x+16
Step 1: Simplify both sides of the equation.
−4(x+2)=8x+16
(−4)(x)+(−4)(2)=8x+16(Distribute)
−4x+−8=8x+16
−4x−8=8x+16
Step 2: Subtract 8x from both sides.
−4x−8−8x=8x+16−8x
−12x−8=16
Step 3: Add 8 to both sides.
−12x−8+8=16+8
−12x=24
Step 4: Divide both sides by -12.
−12x
−12
=
24
−12
x=−2
Answer:
x=−2
Answer: x ≥ 4
<u>Step-by-step explanation:</u>
x + 10 ≥ 14
Subtract 10 from both sides of the equation:
x ≥ 4
Graphing:
> and < symbols represent an open dot
≥ and ≤ symbols represent a closed dot
Since the solution is: x ≥ 4, we will use a closed dot and the arrow will point to the right of 4.

sorry I don't solve this problem
Answer:
x + y + z = 272 - - - - - - (1)
x = 3y - - - - - - - - - - - - - (2)
z = 32 + y - - - - - - - - - - (3)
Step-by-step explanation:
Let :
Number of pop songs = x
Number of rock songs = y
Number of hophops = z
Sum of the three types of songs = 272
x + y + z = 272 - - - - - - (1)
Pop is 3 times Rock :
x = 3y - - - - - - - - - - - - - (2)
Hiphop is 31 more than rock
z = 32 + y - - - - - - - - - - (3)
