$\huge\bigstar\:$ $\Huge\tt\underline\blue{ANSWER}$

2(y - 1) = 0

2y - 2 = 0

2y = 0+2

2y = 2

y = 2/2

y= 1

<h3>ANSWER IS 1.</h3>

<h3>Value of 4x is not known </h3>

So, x/2 = 3

x = 3×2

x = 6

So value of 4x = 4×6

<h3>Answer - 24</h3>

What is the area of rhombus ABCD? Enter your answer in the box. Do not round at any steps.

Mrac [35]

Answer:

Area of the rhombus ABCD = 16 square units

Step-by-step explanation:

Area of a rhombus = $\frac{1}{2}(\text{Diagonal 1})(\text{Diagonal 2})$

From the graph attached,

Diagonal 1 = Distance between the points A and C

Diagonal 2 = Distance between the points B and D

Length of a segment between (x₁, y₁) and (x₂, y₂) = $\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^2 }$

Diagonal 1 (AC) = $\sqrt{(4-0)^2+(-1+1)^2}$ = 4 units

Diagonal 2(BD) = $\sqrt{(2-2)^2+(3+5)^2}$ = 8 units

Now area of the rhombus ABCD = $\frac{1}{2}(\text{AC})(\text{BD})$

= $\frac{1}{2}\times 4\times 8$

= 16 units²

Therefore, area of the given rhombus is 16 units².

A number increased by 9 is 13

Alborosie

Answer:

Step-by-step explanation:

To find the number you have to reverse the equation

Let us call the number "x"

x + 9 = 13

So to find x we flip the equation

13 - 9 = x

Solve it

4 = x

So the missing number is 4

grin007 [14]

60 square feet= $287.00 + $80.00

= $367

1 square feet= $367 / 60

= $6.116666667

= $6.12 (to 2dp) ( answer)

13 out of 60 people surveyed were left handed calculate the angle you would use in a pie chart

PtichkaEL [24]

Total angle for the pie chart = 360°

13 out of 60 = 13 / 60

Angle for it = 13 / 60 * 360 = 13 * 6 = 78°

Angle used = 78°
