Lesson 4.3: Question 10
Shree writes the equation x + 7=28. What should Shree do to find the value of x?
Drew should use the inverse operation of addition, which is subtraction, to find the value of x. He will then subtract 7 from both sides of the equation.
Lesson 4.3: Question 7
Solve.
150=e+42
e=108
Lesson 4-9: Question 1.
Write a rule and an equation that represents the pattern in each table.
Rule: the value of y is 2 more than the value of x.
Equation: y=x+2 or x=y-2
Lesson 4-9: Question 2.
Write a rule and an equation that represents the pattern in each table.
Rule: The value of y is the value of x times 3.
Equation: y=3x pr x=y/3
Lesson 4-9: Question 3.
Write a rule and an equation that represents the pattern in each table.
Rule: The value of y is the value of x divided by 4.
Equation: y=x/4 or x=4y
Lesson 4-9: Question 4.
Write a rule and an equation that represents the pattern in each table.
The value of y is 5 less than the value of x
y=x-5 or x=y+5
Lesson 4-9: Question 5.
Use the equation to complete each table.
y= 7, 10, 13, 16
