Answer:

x=\frac{45.5-8}{2.5\\}

Step-by-step explanation:

Each correct answer is 2.5 points

and the bonus was 8 points

and she has a total of 45.5 points

and if "x" was the number of questions she got correct then it's

x=\frac{45.5-8}{2.5\\}

Hope this helps!

(and I wouldn't mind a crown ;-;)

X - 2y &lt; 2<br> graph the inequality
Korvikt [17]

Answer:

y > 1/2x - 1

First, draw the dashed line y = 1/2x - 1 (slope intercept ; y = mx + b).

Start at -1 on the y-axis, and continue going 2 units to the right, and 1 unit up for the right side of the graph.

Then starting at -1 on the y-axis, continue going 2 units to the left, and 1 unit down for the left side of the graph.

Explanation:

Convert standard form (Ax + By = C) by isolating y from the rest of the equation.

Ax + By = C → y = -Ax/B + C/B → y = mx + b.

Given a standard form equation in inequality form,

x - 2y < 2.

Set it to slope-intercept as an inequality to find the slope and y-intercept.

When negating (making opposite) a variable, you flip the inequality.

x - 2y < 2 → x - 2y - x < 2 - x → -2y < -x + 2 → 2y > x - 2 → <u>y > 1/2x - 1</u><u>.</u>

Can you form a right triangle with the three lengths given? Why or why not? 5 cm, 12 cm, 13 cm
nordsb [41]

Yes,  I  form a right triangle with the three lengths given, because The largest side which is 13cm can be squared  and will be set to  equal to the sum of squares of smaller two side.

<h3>What is a right-angled triangle?</h3>

A  right-angled triangle serves as the  triangle having  one of its angles equal to 90 degrees.

It should be noted that the other two angles sum up to 90 degrees., hence  I  form a right triangle with the three lengths given, because The largest side which is 13cm can be squared  and will be set to  equal to the sum of squares of smaller two side.

A business sells kicking tees by mail for 3 each the shipping charge is 5 the function p=n+5 shows how the number of tees n rela
melamori03 [73]

<u>Answer: </u>

When you buy 2 , 3 and 4 tees , price you pay are 10.33 unit price , 13 unit price and 15.667 unit price respectively.

<u>Solution: </u>

Information provided in the question seems to be less . so assuming following two things.

1)Given function p = n + 5 do not include shipping cost as shipping cost is also dependent on number of tees.

2)If shipping charges for 3 tees is 5 , then shipping charges of 1 tee is \frac{5}{3}

When you buy 2 tees , n = 2

Price = p = n+5 = 2+5 = 7

Shipping charges =( \frac{5}{3} ) x 2 = \frac{10}{3}

So total price you pay for two tees = 7 + (\frac{10}{3}) = 7 + 3.3333 = 10.3333 unit price.

When you buy three tees , n = 3  

Price = p = n+5 = 3+5 = 8

Shipping charges =( \frac{5}{3} ) x 3 = 5

So total price you pay for two tees = 8 + 5 = 13 unit price.

When you buy four tees, n = 4  

Price = p = n+5 = 4+5 = 9

Shipping charges =( \frac{5}{3} ) x 4 = \frac{20}{3}

So total price you pay for two tees = 9 + (\frac{20}{3}) = 47/3 = 15.667 unit price.

Hence when you buy 2 , 3 and 4 tees , price you pay are 10.33 unit price , 13 unit price and 15.667 unit price respectively.
