What numbers are greater than 7 x 10^-4? Please help!Choose all answers that are correct. A) 8 x 10^-4 B) 9 x 10^-5 C) 4 x 10^-4 D) 3 x 10^-2 E) 7 x 10^-5
Both the answers are correct. It's just that in one answer, the fraction is in mixed form, and the other answer has it as an improper fraction.
What is the value of z?
Answers
Solve:-
This triangle's angles sum should equal to 180°. Lets find z:-
180 - 62 = 118 118 - 95 = 23
Angle z = 23°
~~~ 30 POINTS ~~~Directions: Write an equation to represent each relationship. Then solve the equation.
1. Two less than 3 times a number is the same as the number plus 10. 2. A number increased by 4 is the same as 19 minus 2 times the number. 3. Twenty less than 8 times a number is the same as 15 more than the number.

1) 3x-2=x+10
Now, lets solve this step-by-step. 3x - 2 = x + 10 -x -x 3x - x = 2x 2x - 2 = 10 2x - 2 = 10 2x - 2+2 = 10+2 The inverse operation helps isolate the variable. 2x = 12
2x/2 = 12/2
x = 12/2 x = 6
Answer: x = 6
2) x + 4 = 19 - 2x
We can solve this much faster
x + 4 = 19 - 2x +2x
x+2x = 3x
3x + 4 = 19 -4 -4
19-4 = 15
3x= 15 3x/3 = 15/3 x= 5
Answer: x = 5
3) 8x - 20 = x + 15
Much faster now!!
8x - 20 = x + 15 -x 8x-x = 7x
7x - 20 = 15 +20 +20 15+20 = 35
7x = 35 7x/7 = 35/7 x = 35/7 x = 5
Answer: x= 5
let x be the unknown number of all 3 equations 1.) 3x - 2 = x + 10 x=6 2.) x + 4 = 19 - 2x x=5 3.) 8x - 20 = x + 15 x=5

Can the sum of two mixed numbers be equal to 2, explain why or why not
Answers
no because a mixed number is a whole number with a fraction and the smallest whole number is one so 1 and a fraction pulse and a fraction will equal more than 2
