Find value of 2x+2y if x+2y = 6 and x+y = 10

Mathematics

AleksAgata [21]1 year ago
5 0

Step-by-step explanation:

x + 2y = 6 \:  \: equ1 \\ x + y = 10 \:  \: equ2

From equ2,

x = 10 - y

Substituting the value of x in equ1,

(10 - y) + 2y = 6

Collect like terms

y=6-10

y = - 4

Substituting the value if y in equ2,

x+y=10

x+(-4)=10

x-4=10

x=10+4

x=14

Therefore, 2x+2y

2(14) + 2(-4)

28 - 8

=20

The first hexagon is dilated to form the second hexagon. Select answers from the drop-down menus to correctly complete the state
Varvara68 [4.7K]

Answer:

Scale factor = 4 and it represents an 'enlargement'.

Step-by-step explanation:

We are given a hexagon which is dilated to form the second hexagon.

Now, as the size of the original hexagon is 0.2 units and the size of the dilated hexagon is 0.8 units.

As we get that 0.2 × 4 = 0.8

Therefore. it can seen that the original hexagon is dilated by 4 units in order to obtain new hexagon.

Moreover, dilation refers to the transformation that changes the size of the image.

Now, as we are changing the size by a scale factor of 4. So, this dilation is increasing the size of the original hexagon.

Hence, this dilation represents an enlargement.

mrs jones gave 1/5 of a cake to her neighbour. she then sliced the remainder into 3 pieces for her 3 children, ken, ron and davi
Arturiano [62]

The fraction of the cake that was ron's pieces is 1/5.

<h3>What is the fraction of the cake was ron's pieces?</h3>

Ratio demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B).

Since Mrs Jones gave 1/5 of a cake to her neighbour, the remaining fraction will be:

= 1 - 1/5

= 4/5

The fraction of the cake that was ron's pieces will be:

= 2/(1+3+4) × 4/5

= 2/8 × 4/5

= 8/40

= 1/5
