you multiply all numbers by all numbers i have example
Answer:
cannot be determined
Step-by-step explanation:
you know they are similar triangles because their angles are congruent, but you cannot determine if they are the same because you are not given that any of their sides are congruent
First, distribute.
{8x-11(x-2)=-8}
{8x-11x+22=-8}
Next, add up the variables.
{8x-11x+22=-8}
{-3x+22=-8}
Then, move 22 to the other side.
{-3x+22=-8}
{-3x=-30}
Finally, divide each side to get your answer.
{-3x=-30}
<em>x=10</em>
Answer:
Shaquille made 10 two-point baskets and 15 free throws.
Step-by-step explanation:
To solve this, we need to set up a system of equations in which the first equation is the total number of baskets. Let x equal free throws and y equal two-point baskets.
x + y = 25
The next equation can be for his total number of points. In this one, two-point baskets must be multiplied by 2, since he gets 2 points for each one he makes.
x + 2y = 40
Now we can use elimination to solve. First multiply the first equation by -1 and then add together.
-x - y = -25
x + 2y = 40
-----------------
y = 15
Now that we have the value of y, we can solve for x.
x + y = 25
x + 15 = 25
x = 10
20/100 = x/12
The 20/100 in the expression represents the 20%. The x in this scenario is the unknown amount in which the person will tip. The /12 is the cost of the original price. So, in order to find the value of x, you would need to cross multiply.
x = $2.40
The total cost would be $2.40 + $12.00 = $14.40
