Which equation matches the statement: "The sum of -4x and 2 is 9"?
A -4x+2=9
B -4x+9=2
C -4x(2)=9*
D -4x-2=9
Solve. 1
___ x = 12
3
A x=4
B x=15
C x=36
D x=39*
Am i correct on these?
#1A "sum" means add. "product" multiply.
#2C I have no idea how you came up with your answer. If you meant
x/3 = 12
then multiply both sides by 3, since 3/3 = 1. Then you have
x = 36
You did the multiplication, and then added another 3. Why? 39 is the solution to
(x-3)/3 = 12
For the equation "The sum of -4x and 2 is 9," the equation that matches it is A) -4x+2=9.
To solve the equation 1/3 * x = 12, we can multiply both sides of the equation by 3 to eliminate the fraction:
(1/3) * x * 3 = 12 * 3
x = 36
So the correct answer is C) x = 36.
For the first question, we need to write an equation that represents the statement "The sum of -4x and 2 is 9." To do this, we'll use the addition operation and the variable x. The equation can be written as -4x + 2 = 9. Therefore, the correct answer is A.
For the second question, we have the equation 1/3 * x = 12. To solve for x, we can multiply both sides of the equation by 3 to isolate x. This gives us x = 12 * 3 = 36. Therefore, the correct answer is C.
So, for the first question, the correct answer is A, and for the second question, the correct answer is C. Well done!
