What does one half of a number is four look like

Kitty [74]

Answer:

$\frac{1}{4} x = 4$

Step-by-step explanation:

$\frac{1}{4} x = 4$

Let's solve:

$\frac{1}{4} x = 4$

4( $\frac{1}{4} x = 4$ )

x = 16

Let's check:

$\frac{1}{4} x = 4$

$\frac{1}{4}(16) = 4$

4 = 4

Hope this helps!

Please help ASAP it is due today

Dmitrij [34]

Answer:

Step-by-step explanation:

What we know

total sum of angles = 540 deg

3/2 b cam also be written as 1.5b degrees.

So 1.5b + (b+45) + (2b - 90) +90 = 540

Step 1 -- get rid of parenthesis

1.5b + b + 45 +2b -90 +90 =540

Step 2 -- combine the like expressions

4.5b + 45 = 540

Step 3 -- subtract 45 from both the sides

4.5b = 495

Step 4 -- divide 4.5 from both the sides

b = 110 ----- not the right answer

Thats not right okay im sorry

but i guess if it is not 110 it should be 100, 90 etc.

90 = b is correct

Hello!

The quadratic formula is

$x = \frac{-b + and - \sqrt{b^{2} - 4ac } }{2a}$

the + and - means that for one solution you add them and for the other you subtract them

Hope this helps!
