Use intercepts to graph the linear equation 5x + 3y = 30.
miv72 [106K]

Answer x=6 and y=10

Explanation:

Replace each variable in turn with 0 and solve

5x+3y=30  Put zero in place of x and solve for y

5(0)+3y=30

\frac{3y}{3} =\frac{30}{3}

y=10 The y- intercept is 10

5x+3y=30 Put zero in place of y and solve for x

5x+3(0)=30

\frac{5x}{5} =\frac{30}{5}

x=6  The x-intercept is 6

$947.50 - $189.50 = ?<br>Am I not smart or what?
VashaNatasha [74]
<span>   $947.50
</span> - $189.50
_________
$758.00

So, to do this first we start at the far right and go to the left.

   $947.50 - $189.50_________
   $      .00
0-0= 0
5-5= 0

You then bring down the decimal.

   $947.50 - $189.50_________
    $   8 .00
Because you cannot subtract 9 from 7, you borrow one from the number to the left of it and 7 turns into a 17 as 4 turns into a 3. So then, 17-9=8.
         17
   $93-7-.50         -7- = This means the 7 has been canceled out and turned  - $189.50                        into the 17 above _________         8 .00
This happens again with subtracting 3 from 8 in which you take one from the number beside which happens to be 9 and make it 8.

          17
   $8-3--7-.50         -7- and -3- = This means the 7 has been canceled out                                                         and turned into the 17 above 
  - $189.50                        _________    $ 58 .00
So then, 13-8=5. Finally 8-1= 7

   $947.50
 - $189.50
_________
$758.00

The formula for the area of a triangle is A=12bh. Solve this equation for b.
aksik [14]

Step-by-step explanation:

Hey there!

Given;

[A = 1/2b*h]

Divide both sides by 'h'.

A/h = 1/2(b*h/h) [ on right side'h' gets cancelled].

Multiply '2' and 'A'.

A*2/h = b

b = 2A/h.
