Find two numbers that have a sum of 77.95 and a difference of 30.61
Answers
let x = the larger number let y = the smaller number we can set up a system of equations with this: x+y=77.95 x-y=30.61 take the second equation: x-y=30.61 add y to both sides, cancelling it out on the left, and you get: x=y+30.61 Now, since we know what x equals(not the exact number, though), we can plug it into the first equation so we can solve for y We take the first equation now: x+y=77.95 substitute x's value into the equation: (y+30.61)+y=77.95 then, using the commutative and the associative property of addition, we can switch the order and parentheses around: (y+y)+30.61=77.95 y+y=2y, so we can simplify the equation to: 2y+30.61=77.95 we subtract 30.61 from both sides: 2y=47.34 divide both sides by 2 to get your smaller number, y: y=23.67 We can substitute y into the second equation now: x-y=30.61 x-23.67=30.61 add 23.67 to both sides to get: x=54.28 So the 2 numbers are 54.28 and 23.67
The answer is:
54.28 and 23.67

Solve|3-v|<6
1.Write the inequality as two inequalities without absolute value.
2.Solve the inequality and write the solution set.
Answers
|3-v| < 6
1) Write the inequality as two inequalities without absolute value: 1st inequality: 3 < 6 2nd inequality: -v < 6
2) |3-v| < 6 -3 -3 |-v| < 3 v < 3
v = 2
3 - v < 6 3 - 2 < 6 1 < 6
What is , 12-1x0+4÷2???
Answers
Your answer is 14 Order of operations First you multiply 12-0+4/2 Second you divide 12-0+2 Last you add all terms neglecting the -0 12+2= 14
2 is the answer because if you subtract 12 to 1 it will be 11 and time by 0 and it will be 0 add by 4 and divide it by 2 and it will be 2.
