How do you subtract 9-3 7/8?

Answers

Answer 1

Answer: you take 9 times 8 which is 72out of 9 and subtract 3 which is 7 and 7/8 out of 7 is 6 and 1/8

Answer 2

Answer: Since 1-7/8=1/8, you have to also subtract 9-3=6. But since there is a fraction, you have to take away and extra one since if it was six it would be too big if you tried to add it back to 3&7/8. It would equal out to 10, so the answer is 5&1/8. If you add that up it equals 9.

Evaluating the function,f(x) = –2x² – 3x + 5 for x = -3, we would have: f(-3) = -4. (option B).

How do you Evaluate a Function?

To evaluate a function, plug in the given value of the input (x) and simplify.

Thus:

f(x) = –2x² – 3x + 5

Substitute x = -3 into the function

f(-3) = –2(-3)² – 3(-3) + 5

f(-3) = -2(9) + 9 + 5

f(-3) = -4

Therefore, evaluating the function,f(x) = –2x² – 3x + 5 for x = -3, we would have: f(-3) = -4. (option B).

Please help me! I’m so confused!! I will give BRAINLIEST :) A coat hanger is in the shape of isosceles triangle ABC shown in the figure. Sides AB and BC are congruent.

If angle BAC = 22 degrees the angle ABC = ?

Answers

Answer:

136 degrees

Step-by-step explanation:

if BAC is 22 degrees, than BCA is also 22 degrees. together that's 44 degrees. triangles are 180 degrees in total so 180 - 44 is 136

Answer:

Angle ABC is equal to 136 degrees.

Step-by-step explanation:

Since sides AB and BC are congruent (meaning they are equal to each other), they will have the same angle measurement. So, angle BAC and angle BCA will both have a measure of 22 degrees.

Triangles always add up to 180 degrees, so add 22 and 22 together, and subtract from 180. This leaves you with 136 degrees for angle ABC.

136 + 22 + 22 = 180, so this works!

I hope this helps!

Find the perimeter and area of a rectangle whose length is (x + 1) and whose width is (x - 3). Express your answer in terms of x. With explanation if you can plz and thx

Answers

Answer:

Perimeter=2L+2w

P=2(x+1)+2(x-3)

P=2x+2+2x-6

P=4x-4

Area=Lxw

A=(x+1)x(x-3)

A=x^2-3x+x-3

A=x^2-2x-3

Step-by-step explanation:

I don't have one :v

Final answer:

The perimeter of the rectangle is 4x - 4 and the area is x^2 - 2x - 3.

Explanation:

The perimeter of a rectangle is calculated by the formula 2*(Length + Width). Hence, the perimeter for the rectangle in question will be 2*((x + 1) + (x - 3)) = 2*(2x - 2) = 4x - 4.

The area of a rectangle is calculated by the formula Length * Width. Therefore, the area for the rectangle equals (x + 1) * (x - 3) = x^2 - 3x + x - 3 = x^2 - 2x - 3.
