Only 3 is needed
Step-by-step explanation:
Step 1,
what i am thinking you're saying is 2x-1/4(12x+4)
so you would distribute the -1/4 to the 12x and the 4.
therefore making it a negative, not a positive.
so, i think step 1 is wrong.
Answer:
The car is going up at a speed of 22.5 mph
Step-by-step explanation:
In this question, we are asked to calculate the speed of a moving car which started moving at an initial velocity for a specific period of time.
To calculate this, we use one of the basic equations of motion;
v = u + at
Where v is the final velocity, u is the initial velocity and t is the time
From the question, we can identify the parameters as follows;
v = ?
u = 10mph
a = 2.5t mph per second for 5 seconds.
Hence a here would be 2.5 * 5 = 12.5
Now, let’s put these values in the equation
v = 10 + 12.5
v = 22.5 mph
Answer: This is very late but but for helping other people in the future, the answer is 33. I took the test and it's correct. Here is a screenshot:
Step-by-step explanation:
Recall that like terms are terms that have the same variable with the same exponent, and that all constants are like terms.
To solve the given equation for y, first, we add like terms:
Now, adding 1.6 to both sides of the equation, we get:
