Solve: r/5 = -9
-
R = -14
-
R = -4
-
R = -45
-
R = 45
Correct Answer
A. R = -45Explanation
To solve the equation r/5 = -9, we can multiply both sides of the equation by 5 to isolate r. This gives us r = -45.Rate this question:

Simplify: 3x + 4 - 8x
-
-5x + 4
-
11x + 4
-
15x
-
-x
Correct Answer
A. -5x + 4Explanation
The given expression is 3x + 4 - 8x. To simplify this expression, we combine like terms by adding the coefficients of x. In this case, we have 3x and -8x, which gives us -5x. The constant term 4 remains unchanged. Therefore, the simplified expression is -5x + 4.Rate this question:

Solve: -2x = 88
-
X = 44
-
X = -44
-
X = 86
-
X = 90
Correct Answer
A. X = -44Explanation
To solve the equation -2x = 88, we need to isolate the variable x. We can do this by dividing both sides of the equation by -2. This gives us x = -44. So, the correct answer is x = -44.Rate this question:

Solve: y - 3 = -5
-
Y = 8
-
Y = -8
-
Y = 2
-
Y = -2
Correct Answer
A. Y = -2Explanation
The equation y - 3 = -5 can be solved by adding 3 to both sides of the equation, which gives y = -2.Rate this question:

To combine like terms, we should...
-
Add & subtract them
-
Multiply & divide them
-
Only add them
-
Only multiply them
Correct Answer
A. Add & subtract themExplanation
To combine like terms, we add and subtract them. Like terms are terms that have the same variable(s) raised to the same power(s). By adding or subtracting like terms, we can simplify an expression and combine similar terms into a single term. This helps us to simplify equations and expressions and make them easier to solve or work with.Rate this question:

What operation should you do first in order to solve the following equation: t/5 = 85
-
Add 5
-
Subtract 5
-
Multiply by 5
-
Divide by 5
Correct Answer
A. Multiply by 5Explanation
To solve the equation t/5 = 85, we need to isolate the variable t. In order to do that, we need to get rid of the division by 5. To do this, we can multiply both sides of the equation by 5. This will cancel out the division and give us t = 85 * 5, which simplifies to t = 425. Therefore, the correct operation to do first is to multiply by 5.Rate this question:

Simplify: 7p - 5m + 6p + 3m
-
13p + 8m
-
13p - 2m
-
P + 8m
-
21pm
Correct Answer
A. 13p - 2mExplanation
The given expression involves adding like terms. The terms 7p and 6p can be combined to give 13p. Similarly, the terms -5m and 3m can be combined to give -2m. Therefore, the simplified expression is 13p - 2m.Rate this question:

What operation should you do first in order to solve the following equation: -9 + x = 43
-
Add 9
-
Subtract 9
-
Multiply by -9
-
Divide by -9
Correct Answer
A. Add 9Explanation
To solve the equation -9 + x = 43, you need to isolate the variable x. Since -9 is being added to x, the opposite operation would be to subtract 9. By subtracting 9 from both sides of the equation, you will be left with x = 52.Rate this question:

Simplify: -6(x + 5) + 2x
-
-4x + 30
-
-4x + 5
-
8x + 5
-
-4x - 30
Correct Answer
A. -4x - 30Explanation
The given expression can be simplified by distributing the -6 to both terms inside the parentheses. This results in -6x - 30 + 2x. Combining like terms, we get -4x - 30. Therefore, the correct answer is -4x - 30.Rate this question:
