X^5 & x^5. both of the answers are the same even though the expressions were different at the start. the results relate to the addition property from multiplication (with a negative number) and the subtraction property (with positives) from division.
What do the radius and height? There is no picture.
Answer:
No
Step-by-step explanation:
Because according to the crane capacity, it can actually lift up to 95,000 ounces.
According to that,
- You have to convert 95,000 ounces to tons to determine the real capacity in that unit . To convert a ounce measurement to a ton measurement. The formula is:
1 tons = 3.125E-5 ounces
The weight in tons is equal to:
95,000 oz = (95,000 × 3.125E-5) = 2.96875 t
So the crane can not safely lift a load 95,000 ounces.
Answer:
x=5, y=2
Step-by-step explanation:
You simply write down what you see:
3x - 4y + 4x - 5y = 17
2x - 3y + 3x - 5y = 9
Then you simplify by grouping the x and the y terms:
7x - 9y = 17
5x - 8y = 9
Now you want to get equal amounts of x or y. Let's go for x. If we multiply the top eq with 5 and the bottom one with -7, we get:
35x - 45y = 85
-35x + 56y = -63
-------------------------+ now we can add them:
11y = 22 divide by -11
y = 2
So 7x - 18 = 17, x =5
Finally, it makes sense to double check by filling in these answers in the original equations, just to see if no mistakes were made:
3*5 - 4*2 = 7
4*5 - 5*2 = 10
7+10 = 17: ok!
2*5 - 3*2 = 4
3*5 - 5*2 = 5
4+5 = 9: ok!
