Answer:
Step-by-step explanation:
Sum: 6 * 10^-4 + 1.5*10^-4 = 7.5 * 10^-4
Difference: 6 * 10^-4 - 1.5 * 10^-4 = 4.5 * 10^-4
Product: 6*10^-4 * 1.5 * 10^-4 = 9 * 10^-8
Quotient: 6*10^-4/1.5 * 10^-4 = 4
Notice the answers, because they give you the rules.
When adding exponents and rationales, if the powers are the same then the rationales merely add.
Same rule applies to subtraction. Retain the powers and subtract the rationales.
When multiplying the rationales multiply, but the rationales add. they don't stay the same.
When dividing, the rationales divide and the powers subtract -- numerator minus denominator

Answer:
division property of equality
Step-by-step explanation:
First in order to solve we must learn the properties of equality:
Addition property of Inequality:
If a > b , then a + c > b + c
substraction property of inequality
If a > b , then a - c > b - c
Multiplication property of inequality
If a > b , then a * c > b * c (if c > 0)
Division property of inequality
If a > b , then a / c > b / c (if c > 0)
Step 3: 2x>10
Step 4: x>5
When we divide by 2x/2 and 10/2 we get x>5 so we must use the division property of equality

find three consecutive even integers whose sum 72
Answers
22, 24, 26
Step-by-step explanation:
2n - 2 + 2n + 2n + 2 = 72
6n = 72
n = 72/6
n = 12
∴ so three consecutive even integers whose sum is 72 :
2n - 2
= 2(12) - 2
= 24 - 2
= 22
2n
= 2(12)
= 24
2n + 2
= 2(12) + 2
= 24 + 2
= 26
verification
22 + 24 + 26
= 46 + 26
= 72 ✓✓

Mason is driving on a long road trip. He currently has 12 gallons of gas in his car. Each hour that he drives, his car uses up 1.5 gallons of gas.
Then the amount of the gas in the tank after driving for 2 hours will be
The amount of gas used in 2 hours will be
Used gas = 2 x 1.5
Used gas = 3 gallons of gas
Then the remaining amount will be
Remaining amount of gas = 12 - 3
Remaining amount of gas = 9 gallons

Answer:
x = 10
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
12x + 15 is an exterior angle of the triangle , then
12x + 15 = 4x + 10 + 85 , that is
12x + 15 = 4x + 95 ( subtract 4x from both sides )
8x + 15 = 95 ( subtract 15 from both sides )
8x = 80 ( divide both sides by 8 )
x = 10
