A painting is 2 in tall and 3 in wide. If it is enlarged to a width of 15 in then how tall will it be?
vekshin1

Answer:

10 in

Step-by-step explanation:

Old proportions:

2 x 3

New proportions

h x 15

Assuming the painting has been increased by a constant scale factor.

Where x is the unknown scale factor, and h is the height after it has been enlarged.

3 * x = 15\\2 * x = h

Rearrange second equation:

3 * x = 15\\x =\frac{h}{2}

Substitute:

3*\frac{h}{2} =15\\\frac{h}{2}=5\\h=10

A rectangular vegetable garden will have a width that is 4 feet less than the length, and an area of 140 square feet. If x repre
UNO [17]

Answer:

The length of the garden=14 feet

Step-by-step explanation:

<em>Step 1: Determine the dimensions of the garden</em>

length of the garden=x feet

width of the garden=(x-4) feet

<em>Step 2: Determine the area of the garden</em>

Area of the garden=length×width

where;

area=140

length=x

width=x-4

replacing'

x(x-4)=140

x²-4x-140=0, solve the quadratic equation;

x={-b±√(b²-4ac)}/2a

x={4±√4²-4×1×-140}/2×1

x={4±√(16+560)}/2

x={4±√576}/2

x=(4±24)/2

x=(4+24)/2=14, or (4-24)/2=-10, take x=14

The length=14 feet, width=(14-4)=10 feet

The length of the garden=14 feet

Four times the dference of a number and three is twelve find the number
3241004551 [841]

the number is 6

let the number be n , then the difference of this number and 3 is n - 3

4 times this is 4(n - 3) = 12 ( solve for n )

divide both sides by 4

n - 3 = 3 ( add 3 to both sides )

n = 3 + 3 = 6

the number is 6
