Answer:
The answer is 7,2
Step-by-step explanation:
All of the numbers are different like possitive, negitive. and negitive, negitive along with negitive, possitive leaving us left with possitive, possitive and if you look on a coordinate plane you can make a rectangle with all of these coordinates put together. Hope this helps! :D
Answer:
<em>(-2)2 - (-8) + 1</em>
Step-by-step explanation:
When you substitute values into an algebraic equation, you need to input the values exactly how they are given. "w" must go where there are "w"s, and "v" must go where the "v"s are, otherwise you will get an incorrect answer. All values must also carry over their signs--they are one unit--and must be inserted as such, which is why - (-8) is correct, but not - (8) or - 8. (This is because those two negatives will cancel each other out and become +8 when solving). The parenthesis around the values are important because they protect the original values of the variables, which is why (-2)2 is correct. In the case of (-2)2, it also signifies that they are "attached" by multiplication, and when solving would become -4. Without signifying that the variables are separate from the rest of the equation via the parenthesis, it becomes very easy to solve it incorrectly.
Answer:
120 miles.
Step-by-step explanation:
Use long division to find how many miles the car travels in 1 hour then we multiply by 4
: (7÷210=30)×4=120miles. Hope this helped ;D
7= 16 + 3x
7-16 = 3x
-9 = 3x
x = (-9)/(3)
x = -3
