Answer:

x=15.1°

Step-by-step explanation:

Angles in an equilateral triangle adds up to 180°

(4x - 10) + (3x - 22) + (3x + 3) = 180

Putting the like terms together;

4x + 3x + 3x - 10 - 22 + 3 = 180

10x - 29 = 180

10x = 180 - 29 = 151

x = 151/10 = 15.1°

zmey [24]

Answer: 216/343 or 0.6297

Step-by-step explanation:

$14-14x^{1/3} = 2\\14 -2 = 14x^{1/3}\\12 = 14x^{1/3}\\\frac{12}{14} =x^{1/3}\\\frac{6}{7} =x^{1/3}\\(\frac{6}{7})^3 =(x^{1/3})^3\\\frac{6^3}{7^3} =x\\\\\frac{216}{343} = 0.629737609 = x$

the area of a parallelogram is 36x^6y^5. if the base of the parallelogram is 3xy^2,what is the height of the parallelogram asap

trapecia [35]

Answer:

h = 12x^5y^3

Step-by-step explanation:

The area of a parallelogram is found using A = b*h. Substitute the values given and solve for h.

A = b*h

36x^6 y^5 = 3xy^2 * h

36x^6 y^5 ÷ 3xy^2 = h

12x^5y^3 = h

Harman [31]

Answer:

Let's solve for x.

4x−2y=20

Step 1: Add 2y to both sides.

4x−2y+2y=20+2y

4x=2y+20

Step 2: Divide both sides by 4.

4x/4

= 2y+20/4

x= 1/2y+5

Answer: x= 1/2y+5
