To win a trivia game, Nathan must score at least 75 points. Each correct answer is worth 2 1/2 points , and each incorrect answe

Dmitrij [34]

Answer:

He scored $79\frac{1}{2}$ points.

Step-by-step explanation:

Given:

Number of points for a correct answer = $2\frac{1}{2}$

Number of points scored for an incorrect answer = $-\frac{1}{4}$

Therefore, for 35 correct answers, points scored = $35\times 2\frac{1}{2}=35\times \frac{5}{2}=\frac{175}{2}$

Now, for 32 incorrect answers, points scored = $32\times -\frac{1}{4}=-\frac{32}{4}=-8$

Therefore, net number of points scored by Nathan is:

$\frac{175}{2}-8=\frac{175}{2}-\frac{16}{2}=\frac{175-16}{2}=\frac{159}{2}=79\frac{1}{2}$

Therefore, Nathan scored $79\frac{1}{2}$ points.

Someone pelase help me!!!!

Answer:

$\boxed{\bold{True}}$

Step By Step Explanation:

Equation One:

Multiply Both Sides By One (Reverse The Inequality)

$\bold{\left(-\frac{2}{5}x\right)\left(-1\right)$

Simplify

$\bold{\frac{2}{5}x$

Multiply Both Sides By 5

$\bold{5\cdot \frac{2}{5}x$

Simplify

$\bold{2x$

Divide Both Sides By 2

$\bold{\frac{2x}{2}$

Simplify

$\bold{x$

-------

Equation Two:

Subtract $\bold{\frac{3}{4} }$ From Both Sides

$\bold{-x+\frac{3}{4}-\frac{3}{4}$

Simplify

$\bold{-x$

Multiply Both Sides By -1 (Reverse The Inequality)

$\bold{\left(-x\right)\left(-1\right)>\frac{37\left(-1\right)}{4}}$

Simplify

$\bold{x>-\frac{37}{4}}$

the sum of three decimal numbers is 6 exactly one of the numbers is less than 1 what could the numbers be

sleet_krkn [62]

The 3 numbers could be 0.5, 1.1 and 4.4.

In the list above, there is only 1 number less than 1. It is 0.5.
The other 2 numbers are larger than 1.

If you add up the 3 numbers you will have exactly 6.

0.5 + 1.1 + 4.4 = 6
