What value is a sulution of 8+2x≥12 but is not a solution of 8+2x>12?
Answers
Answer:
2
Step-by-step explanation:
We know that in 8 + 2x >= 12, x must be 2 or greater
If we plug in the value 2 in the SECOND equation: 8 + 2x > 12, it won't work because 8 + 2(2) = 12
So we know that the value is 2

The length-to-width ratio of a television screen is 4 to 3. Mya bought a television with a length of 60 inches. What is the width of the television?
a. 45 inches
b. inches
c. 50 inches
d. 52 inches
Answers
Answer:
A
Step-by-step explanation:
Since the first screen, the length is 4 and width is 3, you multiply until you get to 60. 4×15=60, so what is 3×15? 45.
Answer: A
Step-by-step explanation:
Length ratio = 4x
Width ratio = 3x
Length = 60
∴ So, that means, 4x = 60
x = 15
Now, Width = 3*15 = 45 inches
Option (a) is correct

8 5/12 - 6 3/4 (be sure to simplify if necessary)
Answers
Answer: 1 8/12 or simplified as 1 2/3
Step-by-step explanation: add 1/4 or 3/12 to the question to make it 8 5/12 - 7 and then use basic facts to get an answer of 1 5/12. Plus the addition of 3/12 we added before to get your final answer 1 8/12 simplified as 1 2/3.
Step-by-step explanation:
8 5/12 - 6 3/4
convert to improper fraction
8 x 12 + 5 = 101/12
6 × 4 + 3 = 27/4

Solve the system of linear equations by substitution
5y=10
x-3y=4
Answers
Step-by-step explanation:
To solve the system of linear equations by substitution, we'll use the equation 5y = 10 to solve for y. We'll substitute this value of y into the second equation to get an equation in terms of x. Then, we'll solve for x and substitute the value of x back into one of the equations to find y.
Starting with the first equation:
5y = 10
y = 2
Next, we'll substitute this value of y into the second equation:
x - 3y = 4
x - 3(2) = 4
x - 6 = 4
x = 10
Now that we have found x, we can substitute it back into one of the equations to find y:
5y = 10
y = 2
So the solution to the system of linear equations is (x, y) = (10, 2).
Answer: (x, y) = (10 , 2)
Step-by-step explanation: 1. Solve the equation for y: {y=2
{x-3y=4
2. Substitute the given value of y into the equation x-3y=4: x-3x2=4
3. Solve the equation for x: x=10
4. The possible solution of the system is the ordered pair (x, y): (x, y)=(10, 2)
5. Check if the given ordered pair is the solution of the system of equations: {5x2=10
{10-3x2=4
6. Simplify the equalities: {10=10
{4=4
7. Since all of the equalities are true, the ordered pair is the solution of the system. --> (x, y)=(10, 2)
So then, in conclusion, the solution must be, (x, y)=(10, 2).

what is the answer 6 – 2(x + 4) ≤ 8?
Answers
Answer:
x ≥ -5
Step-by-step explanation:
1. Distribute the -2 through the parentheses
-2(x + 4) = -2x - 8
2. Combine like terms ( 6 plus -8)
6 - 2x - 8 ≤ 8
-2 - 2x ≤ 8
3. Move the constant to the right-hand side and change its sign
-2x ≤ 8 + 2
4. Combine like terms
-2x ≤ 8 + 2
-2x ≤ 10
5. Divide on both sides
-2x /-2= cancels out ≤ 10/-2 = -5
x ≥ -5
Tip: if you have a negative x value you must flip the sign

Three friends each have some ribbon. Carol has 90 inches of ribbon, Tino has 4.5 feet of ribbon, and Baxter has 4.5 yards of ribbon. Express the total length of ribbon the three friends have in inches, feet, and yards.
Answers
Total inches: 306
Total feet: 25.5
Total yards: 8.5
Explanation:
90 inches converted to inches= 90 inches
4.5 yards converted to inches= 162 inches
4.5 feet converted to inches= 54 inches
90 + 162 + 54= 306 inches
90 inches converted to feet= 7.5
4.5 yards converted to feet= 13.5
4.5 feet converted to feet= 4.5
7.5 + 13.5 + 4.5= 25.5 feet
90 inches converted to yards= 2.5
4.5 yards converted to yards= 4.5
4.5 feet converted to yards= 1.5
2.5 + 4.5 + 1.5= 8.5 yards
Answer:
Step-by-step explanation:
Let's convert every measurement into inches for now.
90 inches = 90 inches
4.5 feet = 54 inches
4.5 yard = 162 inches
Now, 90 + 54 + 162 = 306 inches
90 inches = 7.5 feet
4.5 feet = 4.5 feet
4.5 yard = 13.5 feet
Now, 7.5 + 4.5 + 13.5 = 25.5 feet
90 inches = 2.5 yards
4.5 feet = 1.5 yards
4.5 yards = 4.5 yards
Now, 2.5 + 1.5 + 4.5 = 8.5 yards
