Solve for x: 4 = (–8) +3x show your work

Answers

4 = (-8) + 3x

Firstly, you can rearrange the equation to make it easier to read:
3x - 8 = 4

Add 8 on both sides to isolate the x:
3x = 12

Divide both sides by 3:
x = 4

Rita and Tina each make $11 an hour working as cashiers at a supermarket. Last week, Rita worked r hours while Tina worked t hours. Rita also worked overtime hours during the week, for which she was paid an extra $32 flat wage. Which expressions represent the total weekly wages of both Rita and Tina?

Answers

For Rita
=> 11 dollars (r) + 32 dollars - r is for the number of hours she worked and the additional 32 dollars is for her over time.
For TIna
=> 11(t) - T is for the number of hours tina worked in the supermarket.

Answer: Equation for Tina be $11t$

Equation for Rita be $11r+32$

Step-by-step explanation:

Since we have given that

Number of hours Rita worked for = r

Number of hours Tina worked for = t

Cost per hour = $ 11

Amount for overtime Rita earned = $32

So, the equation expressing total weekly wage for Tina be $11t$

The equation expressing total weekly wage for Rita be $11r+32.$

How to simplify -64^(1/3)

Answers

$-64^{(1)/(3)}=\sqrt[3]{-64}= \sqrt[3]{(-4)^3} =-4$

You need to find a number that you can multiply by itself 3 times and wind up with -64 .

Like [ N x N x N = -64 ] .

Try some small numbers:

1 x 1 x 1 = 1
2 x 2 x 2 = 8
3 x 3 x 3 = 27
4 x 4 x 4 = 64 . . . There it is ... almost ! The right number, but the wrong sign.

Now try (-4).

Translate the following sentence into an equation. Subtracting 5 from the quotient of a number and 6 gives 37.

Triangle D F G is shown. The length of D F is 11, the length of F G is 6, and the length of D G is 9. Heron’s formula: Area = StartRoot s (s minus a) (s minus b) (s minus c) EndRoot What is the area of triangle DFG? Round to the nearest whole square unit. 27 square units 38 square units 364 square units 728 square units

Answers

Answer:

27 square units

Step-by-step explanation:

To use Heron's formula, you need to know that "s" represents half the perimeter.

s = (11 +6 +9)/2 = 13

Then the area is given by the formula as ...

A = √(13(13 -11)(13 -6)(13 -9)) = √(13·2·7·4) = √728

A ≈ 26.98 ≈ 27 . . . square units

27 units

To find the perimeter, you need the lengths of all 3 legs,
and then you add them up.

Can you find the lengths of the other 2 sides of that triangle ?

Here are a couple of factoids I learned in 1954 and I never forgot:

In a 30°- 60°- 90° right triangle . . .

-- the side opposite the 30° angle (the shorter leg)
is 1/2 the length of the hypotenuse,
and
-- the side opposite the 60° angle (the longer leg)
is (1/2 the length of the hypotenuse) times (√3).

If you have a 30°- 60°- 90° triangle and you know the length
of any one side, then you can find the lengths of the other
two sides with these amazing factoids.
