Solve this one 0.2=x/5-1.4

Mathematics
1 answer:
Dvinal [7]3 years ago
7 0

Answer:

<h2>x = 8</h2>

0.2 =  \frac{x}{5}  - 1.4

Move 1.4 to the left side of the equation

That's

0.2 + 1.4 =  \frac{x}{5}  \\  \\  \frac{x}{5}  = 1.6

Convert the decimal to fraction

That's

1.6 = 8/5

\frac{x}{5}  =  \frac{8}{5}

Multiply through by 5

We have

\frac{x}{5}  \times 5 =  \frac{8}{5}  \times 5 \\  \\  \\ x = 8

Hope this helps you

How do you do solve this?
solniwko [45]
The relative frequency is the frequency of the item divided by the total number of all items. The total number of all items here is: 50 + 40 + 90 +20 = 200.

Burgers =  \frac{50}{200} = 25%
Pasta =  \frac{40}{200} = 20%
Pizza =  \frac{90}{200} = 45%
Salad =  \frac{20}{200} = 10%

Hope this helps!

The variables a, b, and c represent polynomials where a = x 1, b = x2 2x − 1, and c = 2x. what is ab c in simplest form?
inna [77]
If you would like to write a * b + c in simplest form, you can do this using the following steps:

a = x + 1
b = x^2 + 2x - 1
c = 2x
a * b + c = (x + 1) * (x^2 + 2x - 1) + 2x = x^3 + 2x^2 - x + x^2 + 2x - 1 + 2x = x^3 + 3x^2 + 3x - 1

The correct result would be x^3 + 3x^2 + 3x - 1.

Which equation could represent a circle with a center located at (11,-5)
Anon25 [30]
The standard equation of a circle is:

(x-h)^2-(y-k)^2=r^2 where (h,k) is the center and r is the radius.

We need to make an equation of a circle, whose center is (11,-5) with any radius. Therefore, substitute the value.


(x-h)^2-(y-k)^2=r^2 \\ (11,-5)=(h,k) \\ (x-11)^2-(y-5)^2=64

The bolded part is your answer. Since the radius is not given, we can put any value.

PLEASE EASY HELP*****
frez [133]

Answer:

B

Step-by-step explanation:

Multiply through by x+5

2(x + 1) = x + 5 - 1            Combine like terms

2x + 2 = x + 4                 Subtract 2 from both sides.

2x = x + 4 - 2

2x = x + 2                         Subtract x from both sides.

2x - x = 2                          Combine

x = 2

B
