A = 10 or a = -10
When you square a number, you're essentially multiplying it by itself.
Recall that multiplying two negative numbers will result in a positive numbers. Knowing this, we know that -10 times -10 equals 100.
Four thousand one hundred eighty
Answer:
30 miles
Step-by-step explanation:
Alr so-
You want first divide 3 by 3/5 since well- the question asks how many does he ride in 3 hours
Of course, you'll get the answer 5
Now you want to grab the 6 miles Jake could ride in 3/5 hours and put it in a new equation.
(you'll also want to take the 5 you got from the last equation)
You want to multiply both 6 and 5 which is 30
BOOM!
IN CONCLUSION-
the answer is 30 miles
Answer:
(1) 12 boxes (2) 1173 points
Step-by-step explanation:
(1) Jamie needs to fit all if his toys in the boxes, so you would need to do 103 times 9, making it 11.4. So, you'd need twelve boxes to fit all of he toys into boxes.
(2) The contestant earned 69 points, and each of those points are worth 17 points, meaning you have to do 17 times 69, which is 1173
.
Simplifying
(0.75x + 6) + -1(2.5x + -1.9) = 0
Reorder the terms:
(6 + 0.75x) + -1(2.5x + -1.9) = 0
Remove parenthesis around (6 + 0.75x)
6 + 0.75x + -1(2.5x + -1.9) = 0
Reorder the terms:
6 + 0.75x + -1(-1.9 + 2.5x) = 0
6 + 0.75x + (-1.9 * -1 + 2.5x * -1) = 0
6 + 0.75x + (1.9 + -2.5x) = 0
Reorder the terms:
6 + 1.9 + 0.75x + -2.5x = 0
Combine like terms: 6 + 1.9 = 7.9
7.9 + 0.75x + -2.5x = 0
Combine like terms: 0.75x + -2.5x = -1.75x
7.9 + -1.75x = 0
Solving
7.9 + -1.75x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7.9' to each side of the equation.
7.9 + -7.9 + -1.75x = 0 + -7.9
Combine like terms: 7.9 + -7.9 = 0.0
0.0 + -1.75x = 0 + -7.9
-1.75x = 0 + -7.9
Combine like terms: 0 + -7.9 = -7.9
-1.75x = -7.9
Divide each side by '-1.75'.
x = 4.514285714
Simplifying
x = 4.514285714
