Answer:
2x + 10
Step-by-step explanation:
To expand (using the distributive property) <u>multiply</u> the number outside the bracket i.e. in this case '2', with the <u>values inside the brackets</u>.
So multiply '2' and 'x' and '2' and 5' and add or subtract on basis of whether the second value is positive or negative.
So
2(x + 5)
= (2*x)+(2*5)
=2x+10
<em>extention note:</em> <u>be careful</u> when the symbol within the equation within the brackets is a subtraction because it implies that the second value would instead be a negative number and should be treated as such.
an example
2(x-5)
= (2*x)+(2*-5)
=2x -10
Anyhow, I hope this helped!
Answer: the answer to ur questions will be 54-17=37
Step-by-step explanation:
Answer:
1. A (85)(0.08)=6.90 then (85)(0.18)=15.30 then 85 + 6.90 + 15.30 =107.10
2. 82.68
Solving;
She was charged $65 before tax. She had to pay a 6% tax (65)(0.06)=3.90 then 65+3.90=68.90
After this she added 20% of the amount after tax rather 20% of 68.90
68.90(0.20)=13.78 then 68.90+13.78=82.68
Change the improper fraction to mix number
So -23/6 = -3 5/6
Make a number line with (on the left) -4, -3, -2 -1 , 0 , 1, 2, 3, 4
Then put a dot very close to -4 BUT not on -4
