John caught 18 fishes and Peter caught 30 fishes.

Step-by-step explanation:

Let,

Fishes caught by John = x

Fishes caught by peter = y

Total fishes caught = 48

According to given statement;

x+y=48 Eqn 1

x= $\frac{3}{5}y$ Eqn 2

Putting Eqn 2 in Eqn 1;

$\frac{3}{5}y+y=48$

Multiplying each term by 5;

$5*\frac{3}{5}y+5*y=48*5\\3y+5y=240\\8y=240$

Dividing both sides by 8

$\frac{8y}{8}=\frac{240}{8}\\y=30$

Putting y=30 in Eqn 1

$x+30=48\\x=48-30\\x=18$

John caught 18 fishes and Peter caught 30 fishes.

Write each equation in standard form using integers? y = 3x + 1 y = 4x - 7

Maru [420]

Answer:

The standard form of y = 3 x + 1 is -3x + y = 1 .

The standard form of y = 4x - 7 is -4x + y = -7.

Step-by-step explanation:

Here the given equation are:

y = 3 x + 1

and y = 4x - 7

The above equations are of the form: y = m x + C

Now, the STANDARD FORM of the equation is Ax + By = C

Consider equation 1:

y = 3 x + 1

or, y - 3x = 1

or. -3x + y = 1

⇒ The equation -3x + y = 1 is in STANDARD FORM.

Consider equation 2:

y = 4 x - 7

or, y - 4x = -7

or. -4x + y = -7

⇒ The equation -4x + y = -7 is in STANDARD FORM.

The length of a rectangle is 4 less than twice the width. The perimeter of the rectangle is 106 cm. Determine the length of the

horsena [70]

Answer:

Length = 34

Step-by-step explanation:

Perimeter of rectangle = a+a+b+b = 2(a+b)

Let a = length = 2b - 4

Let b = width

Therefore

(2b-4) + (2b-4) + b + b = 106 cm

Bracket off

2b-4+2b-4+b+b = 106cm

Collect like terms

2b+2b+b+b-4-4 = 106cm

6b-8 = 106

6b = 106+8

6b = 114

b = 114÷6

b = 19

To get a
