The width of a rectangle measures (26 – 8c) centimeters, and its length measures

Oksi-84 [34.3K]

Answer:

first one is correct

Step-by-step explanation:

length of a rectangle = 2b - 8c

breadth of a rectangle = 10b + 6c

now , formula to calculate the perimeter of rectangle is

p = 2 (l + w)

no substitute the value of l(length) and w(width)

p = 2{(2b - 8c) + (10b + 6c)}

p = 2(2b - 8c + 10b + 6c)

p = 2(12b - 2c)

p = 24b - 4c

Katarina wrote the standard form of a linear equation as 4x – 2/3 y = 8. Sofiya told her that the equation was not yet in standa

-BARSIC- [3]

The standard form of a linear equation in general is given by:

$ax+by=c$

Now we are given the equation :

$4x-\frac{2}{3}y=8$

In order to convert this into standard equation, we have to eliminate the 3 in the second term on the left side of equation.

Here 3 is in division ,so we have to perform opposite operation of division that is multiplication.

So multiplying both sides by 3 , we have

$12x-2y=24$

So that means option A.Multiply both sides of the equation by 3. The standard form of the equation is 12x – 2y = 24. is the correct advice given by Sofiya.

Suppose y is inversely proportional to x. When x=20, then y=4. Find y when x=35.

Ierofanga [76]

~ : to represent sign of proportionality
y ~ 1/x
y = k/x
x=20, y=4
4 = k/20
k = (20×4) = 80
y = 80/x
x=35, y = 80/35 = 2.29
The proportional constant k = 80
The function is: y = k/x
The new value of y is: 2.29
