1) y = 1x + 95.50
x = number of bandanas

2) y = (1 • 50) + 95.50
$145.50 for 50 bandannas

3) 116.50 = 1x + 95.50
get x by itself

116.50 = 1x+ 95.50
-95.50 -95.50

21 = 1x
divide by 1
21 = x
you get 21 bandannas when you pay $116.50

On a road trip you see a sign “350 km to Indianapolis”. About how many hours will it take you to drive to Indianapolis if you ar

deff fn [24]

Answer:

3.019 hours.

Step-by-step explanation:

In this case they ask us to calculate the time in hours that are in those distances, for this we have the speed and the distance, we know that speed is equal to:

v = d / t

therefore the time would be:

t = d / t

we must pass the distance that is in kilometers to miles, like this:

350 km * 1 mile / 1.61 km = 217.4 mi

Now if replacing:

t = 217.4 / 72 = 3.019

Therefore, the time would be 3.019 hours.

Solve for x and y. Geometry

Otrada [13]

Answer:

x =106.5

y = 73.5

Step-by-step explanation:

Angle x is 1/2 arc SPQ

x = 1/2(98+115)

x = 1/2(213)

x =106.5

We know that x+y = 180 since this is an inscribed quadrilateral in a circle

x+y=180

106.5 +y =180

Subtract 106.5 from each side

106.5-106.5 +y =180-106.5

y = 73.5

On a math test, Johnny made a raw score of 95 on a 40 question test. The correct answers were given 5 points each while incorrec

Sidana [21]

X - the number of questions he answered correctly
y - the number of questions he answered incorrectly

There were 40 questions on the test.
$x+y=40 \\ y=40-x$

The correct answers were given 5 points each, the incorrect answers were given -2 points each. He made a score of 95.
$5x-2y=95 \\
-2y=95-5x \\
y=-\frac{95}{2}+\frac{5}{2}x
$

Set 40-x and (-95/2)+(5/2)x equal to each other:
$40-x=-\frac{95}{2}+\frac{5}{2}x \\
-x-\frac{5}{2}x=-\frac{95}{2}-40 \\
-\frac{2}{2}x-\frac{5}{2}x=-\frac{95}{2}-\frac{80}{2} \\
-\frac{7}{2}x=-\frac{175}{2} \\
x=-\frac{175}{2} \times (-\frac{2}{7}) \\
x=\frac{175}{7} \\
x=25$

Johnny answered correctly 25 questions.
