Answer:

The test contains 10 three-point questions and 14 five-point questions.

Step-by-step explanation:

The value of x is the number of 3-point questions, and the value of y is the number of 5-point questions, as the problem statement tells you. So, the solution (x, y) = (10, 14) indicates ...

Which of the following comparisons is FALSE?
dybincka [34]

Answer:

A

Step-by-step explanation:

Let's check each one-by-one.

a.

we know 3.79 liters is 1 gallon, so 4 liters IS NOT LESS THAN 1 gallon

THis is false.

b.

We know 1 feet is 0.30 meters, so definitely 1 foot is less than 1 meter.

This is true.

c.

we know around 28.35 grams is 1 ounce, so definitely 25 grams is less than 1 ounce.

THis is true.

d.

We know 1 km is approximately 0.62 miles so 10 km would be around 0.62*10 = 6.2 miles

So definitely 9 miles IS GREATER than 10 km.

THis is true.

So answer choice A is false, only.

A group of students are going on a trip and the trip costs $36.50 per student which
goblinko [34]

Answer:

$18

Step-by-step explanation:

Let's subtract the lunch from the trip total to get the remainding cost!  

36.50 - 9.50 =  $27

Now let's set up an equation to figure out the amount of the entrance ticket and the gift coupon!

let's have x = the entrance ticket

27 = x + 1/2(x) -----------> 1/2 is next to x, because the gift coupon is 1/2, or 50% of the entrance ticket! Now solve for x!

27 = 3/2x

(2/3) 27 = 3/2x (2/3)

18 = x, so the entrance ticket is $18!

Which of the following are true statements? Select all that apply.
Savatey [412]
You are probably expected to choose ...
  • All integers are rational numbers.
  • Terminating decimals are rational numbers.


However, the premise of ...
  • 0.278254….. is a terminating decimal, therefore it is a rational number.
is False, so the rules of logic allow any conclusion—meaning the implication is True. (As it happens, a repeating decimal is, in fact, a rational number.) So, this, too, is a true statement.

What is the equation for the line that passes through the points (4,2) and (0,6)?
Wewaii [24]

Answer:

The equation is y=-x+6.

Step-by-step explanation:

To find the slope of this equation, we use the equation m=y2-y1/x2-x1, where m is the slope. Take one y coordinate and subtract it from the other and do the same with the x coordinates. Then, divide the difference of the y coordinates by the difference of the x coordinates. For example, 6-2/0-4. This gets us 4/-4. You can also do 2-6/4-0 which gets us -4/4. No matter what, we get -1 for each (we don't include the 1 in front of the x). To find the y-intercept, plug in the coordinates. For example, do 6=0(-1)+b or 2=4(-1)+b. No matter which you use, you get an answer of b=6. This gives you an equation of y=-x+6. Hope this helps :)
