x = -6
Step-by-step explanation:
7x - 6 = 9x + 6
Add 6, both sides;
7x-6+6 = 9x+6+6
7x=9x+12
Subtract 9x, both sides;
7x-9x = 9x+12-9x
-2x = 12
Divide by same term (-2 in this case);
-2x/-2 = 12/-2
x = -6
Therefore, the value of x is -6
Answer:
32 quarter, 1 quarter,1 dime, and 1 nickel
Step-by-step explanation:
first you know that 4 quarter = 1 dollar so now am going to multiply 4 times 8 equal 32 so now you have 1 quarter and 1 dime and 1 nickel
Answer:
Suppose you have $100 and you spent 6 dollar each day, and your friend has $160 and he/she spent $10 each day. After x days you both have equal amount, find the number of days.
Step-by-step explanation:
Consider the provided information.
We need to write a real world situation that could be modeled by the equation 100-6x=160-10x.
You can use any situation to represents this equation.
The left side of the equation consists of a constant and a variable also the right side of the equation consists of a constant and a variable.
Suppose you have $100 and you spent 6 dollar each day, and your friend has $160 and he/she spent $10 each day. After x days you both have equal amount, find the number of days.
Answer:
C)
Step-by-step explanation:
First, multiply the 2 factors that add up to 8.
1/3 x 2. Since this equation does not have one x but 2 (x and y), we will not subtract or divide any sides.
Divide and multiply 2 by 8 and 1/3. Then, we solve for y.
y = 2/3x - 4
