The correct option is first option: x=t(y-4f)
Further explanation:
Given equation is:
In order to solve the equation for x, we have to isolate x on one side of the equation
Using Subtraction property of equality
Subtracting 4f from both sides
Multiplication property of equality
Multiplying both sides by t
Hence, the correct option is first option: x=t(y-4f)

Answer: the test has 10 multiple-choice questions and 15 Word problems questions.
Step-by-step explanation:
Let x represent the number of multiple-choice questions in the test.
Let y represent the number of Word problems questions in the test.
The total number of multiple-choice and Word problems questions in the test is 25. This means that
x + y = 25
The multiple-choice questions are worth three points and Word problems are worth four points. The test is worth a total of 90 points. This means that
3x + 4y = 90 - - - - - - - - - - -1
Substituting x = 25 - y into equation 1, it becomes
3(25 - y) + 4y = 90
75 - 3y + 4y = 90
- 3y + 4y = 90 - 75
y = 15
x = 25 - y = 25 - 15
x = 10

Brainliest please
(3*8)*6=3*(8*6) illustrates the associative property of multiplication. The associative property is kind of just moving the parentheses, so the first choice would be correct
hope this helps:)
