$\qquad\qquad\huge\underline{{\sf Answer}}$

Let's solve ~

$\qquad \tt \dashrightarrow \:10 {x}^{2} - 25x + 15 = 0$

$\qquad \tt \dashrightarrow \:5(2x {}^{2} - 5x + 3) = 0$

$\qquad \tt \dashrightarrow \:2x {}^{2} - 5x + 3 = 0$

$\qquad \tt \dashrightarrow \:2x {}^{2} - 3x - 2x + 3 = 0$

$\qquad \tt \dashrightarrow \:x(2x - 3) - 1(2x - 3) = 0$

$\qquad \tt \dashrightarrow \:(x - 1)(2x - 3) = 0$

Therefore, the required factors are ~ (x - 1) and (2x - 3)

So, correct choice is B

Vlad1618 [11]

3 = -(-y + 6)

First, simplify brackets. / Your problem should look like: 3 = y - 6
Second, add 6 to both sides. / Your problem should look like: 3 + 6 = y
Third, simplify 3 + 6 to 9. / Your problem should look like: 9 = y
Fourth, switch sides. / Your problem should look like: y = 9

The answer is D) 9.

Ethan Planted a tree that was 1.85 meters tall. Several years later, the tree is 5.30 meters tall. Which equation can be used to

Sergeu [11.5K]

Answer: B. 1.85 + x = 5.30

Explanation:

The starting height of the tree was 1.85 meters. To find the number of meters the tree grew, you would subtract the current height from the previous height.
5.30-1.85=x. This equation is the same as 1.85 + x = 5.30 if you switch the 5.30 and x.

The bill for Dino's lunch was $19.45. He wanted to leave 20% of the total bill as a tip. How much should the tip be?

Salsk061 [2.6K]

You could multiply 19.45 by 0.2 to solve for it, but if you're not using a calculator, then 19.45/5 would be much more convenient and easier.

0.2 is 1/5 in fraction form, which is why we can do that.

19.45/5 = 3.89

Dino should leave $3.89 as a tip.
