So let's break this question down.
You need a bit of both, right? Well we need to calculate how many multiple choices we can do whilst having true/false questions, and not going over or under on points.

So, let's pick a random number, 5. So let's do 8x5, that equals 40.

Ok so now we have our number, 5 multiple choice questions. 
The true/false questions should be easy, just do 3x20 and you get 60.

Answer:

2 multiple choice problems

Step-by-step explanation:

the equations will be...

x=true/false questions

y=multiple choice problems

x+y=30

3x+8y=100

5y=10

<h2>y=2</h2>

In two or more complete sentences, describe the transformation(s) that take place on the parent function, f(x)=log(x), to achiev
matrenka [14]
Transforming f(x) = log(x) to f(x) = log (2x) gives the effect of squashing the graph horizontally (by halving the x-coordinate)

Then from f(x) = log(2x) to f(x) = log (-2x) is reflecting on the y-axis

Then from log(-2x) to log(-2x-4) is to translate by 4 units to the right

Finally from log(-2x-4) to log(-2x-4)+5 is translating the graph up by 5 units

A right triangle is ____ a scalene triangle.<br> Always, sometimes, or never
konstantin123 [22]

Answer: Sometimes

Step-by-step explanation:

This is a very tricky question. We know that in an isosceles triangle, two sides are the same. Because of this, we know that the right angle is always 90 degrees, and the other sides would be 45 degrees each because all triangles add up to 180 degrees. A right triangle could also be scalene, meaning none of the sides are the same, for example a scalene triangle could have sides of 44, 46, and 90 degrees. Rest assured, a right triangle will never be equalateral. Hope this helps :) Merry Christmas

Does somebody knows how to do this?
MrMuchimi

Answer:

Area of the triangle = 6x3/2=18/2=9cm²

now find semicircle then add

area of the semicircle= πr²/2=π6²/2=36π/2=18π

now add and you get

Area of the region = (18π+9)cm²

For the Best Brain:<br><br> fun question:<br> how do I solve y = 10x + 2 when x equals 3
allsm [11]
You would plug in 3 for x, which gives you y = 10(3) + 2, and then you would use PEMDAS, which means you multiply 10 with 3 and then add two which is 32. Therefore y would equal 32. :D :D
