Answer:

5x = y + 6

x = 1/5y + 6/5

Step-by-step explanation:

2x - 3y = 4

2(1/5y + 6/5) - 3y = 4

2/5y + 12/5 - 3y = 4....multiply everything by 5 to get rid of fractions

2y + 12 - 15y = 20

2y - 15y = 20 - 12

-13y = 8

y = - 8/13

Elden [556K]
The first step to take is to plot the coordinates of the figure. Next, we caculate the distances of the sides of the polygon using distance formula given the coordinates of points. Next we get the midpoint of each side and connect them to each other. we calculate again the distances. The resulting figure is composed of four congruent sides but the angles are not perpendicular. The answer is D. rhombus

Estimate the sum for 1,537 times 242 then find the sum
Furkat [3]
It says to estimate first 1,537 turns to 2,000 because the 5 is 5 or more so the 1 becomes 2 and everything else is zeros. Now multiply 2000x 242=484,000 is the Estimation. Now find the correct product for 1,537x242=371,954

The width of a rectangular card is 2 cm lekss than the Tength. The area is 15 cm. Find the length and
Yuri [45]

Answer:

Step-by-step explanation:

Area A = 15square cm

Length L = x

Width w = x - 2

Area = L × w

15 = x(x - 2)

15 = x^2 -2x

x^2 -2x - 15 = 0

Solving by factorization

x^2 - 5x + 3x - 15 = 0

(x^2 -5x) + (3x -15) = 0

x(x - 5) + 3(x - 5) = 0

(x + 3)(x - 5) = 0

(x + 3) = 0 or (x - 5) = 0

x = -3 or 5

Since x can't be negative therefore x is 5cm

Length = 5cm

Width = 5-2 = 3cm
