Answer:
275 is 30% of 916.67
Step-by-step explanation:
We have, 30% × x = 275
or
Multiplying both sides by 100 and dividing both sides by 30,
we have x = 275 ×
x = 916.67
If you are using a calculator, simply enter 275×100÷30, which will give you the answer.
Answer: 11x - 9y - 3
Step-by-step explanation:
Collect like terms - start with x
9x - 8y +2x - 6 - y + 3
11x - 8y - 6 - y + 3
Collect all y terms
11x - 9y - 6 +3
Collect all integers
11x - 9y - 3 - final answer
We can sum two fractions if they have the same denominator, so we have to rewrite both fractions so that they'll have the same denominator.
We can generate equivalent fractions by multiplying both numerator and denominator by the same number.
So, we have
Similarly, we have
Now we can sum the fractions:
Answer:
Okay so there are a few ways you can go about doing this.
Step-by-step explanation:
For number 1 you could say 5 - 7 = -2. I don't know if you need to use the same numbers for both the equations in number one, but 5 x -7 could work too.
For number 2 you could say 2 + 2 = 4 or 3 + 1 = 4. As for __ x __ = -5 you could say 2.5 x -2.5 = -5.
The rule is if you multiply a positive by a negative you get a negative. Just like if you multiply a negative by a negative you get a positive. And if you multiply a positive by a positive you get a positive.
I really hope this helps since it took me a while to understand what you were asking.
Answer:
-6x+104/5
Step-by-step explanation:
Distribute: (4)(x)+(4)(5)+-10x+4/5 = 4x+20+ -10x + 4/5 combine like terms: (4x+-10x) + (20+4/5) simplify: -6x 104/5 answer: -6x+104/5
