The perimeter of a rectangle is 42 centimeters. The length of the rectangle can be represented by (x+4) and its width can be represented by (2x - 7). What equation would you use to solve for x? *

Answers

Answer 1

Answer:

2(x+4) + 2(2x-7) = 42 ( If this is wrong simplify this)

Step-by-step explanation:

The formula for perimeter is (2 x length) + (2 x width), so our equation would be 2(x+4) + 2(2x-7) = 42

Answer 2
I think the answer would be 42:)

Step-by-step explanation:

29x - 3 + 15x + 7 = 18 because these two angles are supplementary

29x + 15x + 7 - 3 = 18044x = 176 divide both sides by 44x = 4

13y - 17 = 29x - 3 because these two angles are alternate

since we know the value of x

13y - 17 = 29 × 4 - 313y - 17 = 11313y = 113 + 1713y = 130 divide both sides by 13y = 10

What is the equation for the line perpendicular to the line y=−x+20 that passes through the point (−4, 2)?

Answers

Answer:

y = x + 6

Step-by-step explanation:

A line that is perpindicular to y = -x + 20 would be y = x. Now, we have to solve for the y-intercept. Knowing the line must cross through (-4,2) we can solve for the y-intercept using the equation y = x which is just up one over one. Going over 4 units to get to x = 0 means going up 4 units to get to y = 6. Now we know the y-intercept is 6. This means the final equation is y = x +6.

Solve the system of equations..
y = 8x - 6
y= 5x +9

Answers

Answer:

x = 5

y = 34

Step-by-step explanation:

Sub y = 8x - 6 into second equation (y = 5x + 9)

8x - 6 = 5x + 9

Rearrange by collecting like terms

8x - 5x = 9 + 6

3x = 15

x = 5

Sub x = 5 into first equation (y = 8x - 6)  

y = (8*5) - 6

y = 40 - 6

y = 34

X=5 and y= 34 are the values

Weight of honeybee = [tex]1.2\times 10^{-1}\ \text{g}[/tex]

Weight of pollen = [tex]6\times 10^{-2}\ \text{g}[/tex]
