sdas [7]

Answer:

Mia's test score is 44 if she got 3 questions wrong.

Mia's test score is (50-2x) if she got x questions wrong.

Step-by-step explanation:

It is given that, Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points.

If she got 3 questions wrong, then

Deducted marks $=2\times 3=6$

Marks obtained by Mia = Total marks - Deducted marks

$=50-6$

$=44$

So, Mia's test score is 44 if she got 3 questions wrong.

If she got x questions wrong, then

Deducted marks $=2\times x=2x$

Marks obtained by Mia = Total marks - Deducted marks

$=50-2x$

So, Mia's test score is (50-2x) if she got x questions wrong.

A rectangle and a triangle have the same area, 72 . The height of the triangle is also the same as the width of the rectangle. T

emmasim [6.3K]

Answer:

Part 1) The height of triangle is $h=8\ in$

Part 2) The width of rectangle is $W=8\ in$

Step-by-step explanation:

step 1

Find the dimensions of triangle

The area of triangle is equal to

$A=\frac{1}{2}bh$

we have

$b=18\ in$

$A=72\ in^{2}$

substitute and solve for h

$72=\frac{1}{2}(18)h$

$144=(18)h$

$h=144/18=8\ in$

step 2

Find the missing dimension of rectangle

we have that

The height of the triangle is the same as the width of the rectangle

therefore

$W=h=8\ in$

What does -4(-8x-8) equal?

slavikrds [6]

Answer:

Lets break it down

( -8 x -8 ) = 64, because a negative x negative always equals a positive

-4 x 64 = -256, because a negative x positive always equals a negative

Your answer is -256.

I hope this helps!
