Omar makes 8 dollars for each hour of work. write an equation to represent his total pay p after working h hours.

1 answer:

6 0

(8 p / h) * <u>"x"</u> h = p (in dollars).
_________________________________

in which: "h" = hours ;
"p" = pay (in units of dollars);
"x" = number of hours.
_________________________________
In the equation, on the left hand side, the unit symbol "h" would "cancel out" to "1" ;
and we would have:
_________________________________
8 p * x = _<u>[total "p"]</u>__

Paulita is buying 4 boxes of fruit loops. she has a coupon for 1.00 off each box. her total bill is 10.36. write and solve an eq

kotykmax [81]

The equation would have to be set up as 4b - 4 = 10.36. This is because you’re buying 4 boxes of fruit loops, and $1 taken off each box is $4 total for all four boxes.

I dont understand this problem

Answer:

D and F

Step-by-step explanation:

$x^{2}+4x+4=12$ can be rewritten as $x^{2} +4x-8=0$ .

From there you can use the quadratic formula $x=\frac{-b±\sqrt{b^{2}+4ac } }{2a}$ (ignore the A, I can‘t seem to remove it), where a=1, b=4, and c=-8.

$x=\frac{-4±\sqrt{4^{2}-4(1)(-8)} }{2(1)}$

Then you get $x=\frac{-4±\sqrt{16+32}}{2}$

Then you get $x=\frac{-4±\sqrt{48} }{2}$

So $x=-2±\frac{4\sqrt{3} }{2}$

Which means $x=-2+2\sqrt{3}$ or $-2-2\sqrt{3}$ which are choices D and F.

Evaluate the expression 4(2x + 3) + 2(x + 1)-7

Svetlanka [38]

4 (2x + 3) + 2 (x + 1) - 7

8x + 12 + 2x + 2 - 7

10x + 7

10x = -7
10x/10 = -7/10

x = -7/10

hope this helps

URGENT EXPLANATION AND SOLVING

Alex787 [66]

$\cfrac{a}{\sin(a)} = \cfrac{b}{\sin(b)} 
$

$\cfrac{31}{\sin(42)} = \cfrac{37}{\sin(x)} 
$

$31\sin(x) = 37 \sin(42)$

$\sin(x) = \cfrac{37 \sin(42) }{31}$

$x = \sin^{-1}(\cfrac{37 \sin(42) }{31} )$

$x = 53 \textdegree$

Answer: 53°
