20 pounds to 16 pounds is what present
ExtremeBDS [4]

Answer:

Decreased by 20%.

16 lbs is 80% of 20 lbs.

Step-by-step explanation:

\frac{y}{100} :\frac{16}{20}

y × 20 = 16 × 100

20y = 1600

20y ÷ 20 = 1600 ÷ 20

y = 80

100% - 80% = 20%

Use simultaneous equations to solve the following. Three kilograms of jam and two kilograms of butter cost $29 and six kilograms
artcher [175]

Answer:

The cost of 1kg jam is $7 and the cost of 1kg butter is $4

Step-by-step explanation:

Let jam = x

butter = y

3x + 2y = 29 -----(1)

6x + 3y = 54 -----(2)

(1)×2 ->

6x + 4y = 58 -----(3)

(3)-(2) ->

y = 4

suby=4into(2)

6x + 3(4) = 54

6x = 42

x = 7

Help me please i don't understand ​
lubasha [3.4K]

Answer:

See below.

Step-by-step explanation:

Variables:

L = length

W = width

P = perimeter

Equations:

L = W + 13

P = 2(L + W)

P = 2(W + 13 + W)

2(W + 13 + W) = 226

2(2W + 13) = 226

2W + 13 = 113

2W = 100

W = 50

L = W + 13 = 50 + 13 = 63

The length is 63 cm, and the width is 50 cm.
