2(x+3)=7x-24
2x+6=7x-24
(move 7x to the left by subtracting from both sides, and move the 6 to the right by subtracting from both sides)
-5x=-30
(divide -5 from both sides to get x by itself, and because the 30 and 5 are both negative, two negatives make a positive)
x=6
hope this helped
First, let's turn this sentence into a mathematical expression:
The quotient of the opposite of 30 and 6 means we're dividing negative 30 by 6. The next part, "plus the opposite of 8" means we want to add -8 to whatever we get from -30/6. So we have:
Answer:
explanation that will help u get ur answer
Step-by-step explanation:
The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.
Answer:
4
Step-by-step explanation:
Here you need not completely solve 7992 squared. You can just take the last digit which in this case is 2 and solve for the square of that digit. 2 x 2 = 4. Now if it was a bigger digit which would result in a two digit number when squared you would take the last digit of that number. But, we don't need to do that here since 2 squared is 4.
Answer:
Ms. Pierce pay $468 for the camera.
Step-by-step explanation:
4% = 4/100 = 0.04
450 * (1 + 0.04) = 450 * 1.04 = 468
