Answer:
3 3/4.
Step-by-step explanation:
Add the whole number first.
Then, add 3/4 3 times.
Simplify:
We now use 2/4 once.
Lamar's family used 3 3/4 ranch in total.
hope this helped.
Statement 2: The number ends with 3
Answer:
4
Step-by-step explanation:
First you need to evaluate the power (exponent).
1 raised to any power is still 1.
Then you need to divide the equation
2 + 6 ÷ 3 ÷ 1
2 + 2
4
Answer:
Step-by-step explanation:
To solve this problem you should follow the PEMDAS rule, which is parentheses, exponents, multiplication, division, addition, and subtraction.
Equation 2: 3m = 4 + 4n
Step 1:
−3(m) = −3(8 + 2n) [Equation 1 is multiplied by −3.]
3m = 4 + 4n [Equation 2]
Step 2:
−3m = −24 − 6n [Equation 1 in Step 1 is simplified.]
3m = 4 + 4n [Equation 2]
Step 3:
−3m + 3m = −24 − 6n + 4n [Equations in Step 2 are added.]
Step 4:
0 = −24 − 2n
Step 5:
n = −12
In which step did the student first make an error?

Step 2
Step 1
Answer:
Step 3
Step-by-step explanation:
Hello
the student made a mistake in the step number 3.
let´s see
in the step number 1 he multiplied by -3 in order to add this new equation with equiation 2 and then eliminate the terms with m
Step one
-3(m)=-3(8+2n)
-3m= -24 - 6 n, it is ok
in step two he simplified, he did it well.
in the step 3 he added the equations
-3m = -24-6n
3m = 4 +4n
_____________
0 = -20-2n
he did not add properly -24+4, here , he made his first mistake.
step 4 is already wrong
continuing..to find n
0= -20-2n
20=-2n
n=-10
Have a great day
