Answer:
alternate angles will be equal, so x = 60
Step-by-step explanation:
it's an equilateral triangle. all angles are equal to 60°. one of them is alternate to x as per the figure, so x = 60°
What are all the solutions to the following
equation?
|10x + 2| =48
Combine like terms and use the properties of equality to get the variable on one side of the equals sign and the numbers on the other side. Remember to follow the order of operations.
Use the definition of absolute value.
Subtract 2 from both sides of the equation.
Divide both sides by 10.
Answer:
4
Step-by-step explanation:
The equation is 2(10+x)=28 where x is the unknown number we are trying to find. Use distrubutive property to combine like terms. 2 times 10 is 20 and 2 times x is 2x. Now we have 20+2x = 28. What you do to one side you must do to the other. 20 minus 20 is 0. 28 minus 20 is 8. Now our equation is 2x is 8. To find 1 x we divided in half. 8/2 is 4 therefore the missing variable is 4.
103 x 47 = 4841 - 8 = 4833
The awnser is 4,833
