1 Multiply integers with same signs. Answer is _______..
2 Multiply integers with different signs. Answer is _______..
3 When a number has no sign it usually means that it is _______.
A..Which expressions below have a positive value and which doesn't?
a.-3x4 b. -17x(-8) c. 5(-2) d. 27x13
e. -1x(-5)x7 f. 11x(-10)x3 g. 9(3-5)
2. Find three numbers whose product is -64. You may use integers from -10 to 10. You may not use the same absolute value twice. Find all possible combinations.
Answer:
You multiply or divide integers just as you do whole numbers, except you must keep track of the signs. To multiply or divide signed integers, always multiply or divide the absolute values and use these rules to determine the sign of the answer.
When you multiply two integers with the same signs, the result is always positive. Just multiply the absolute values and make the answer positive.
Positive x positive = positive
Negative x negative = positive
When you multiply two integers with different signs, the result is always negative. Just multiply the absolute values and make the answer negative.
Positive x negative = negative
Negative x positive = negative
When you divide two integers with the same sign, the result is always positive. Just divide the absolute values and make the answer positive.
Positive ÷ positive = positive
Negative ÷ negative = positive
When you divide two integers with different signs, the result is always negative. Just divide the absolute values and make the answer negative.
Positive ÷ negative = negative
Negative ÷ positive = negative

Raul is performing an experiment. He pours water into a glass and measures the temperature of the water at 72.3°F. Then he adds a few ice cubes to the glass of water. He measures the temperature of the water again and finds that it has changed by -39.1°F. Write an expression that represents the temperature (in degrees Fahrenheit) of the water after Raul added the ice cubes. Write the expression as the sum of two numbers.
Answer:
Step-by-step explanation:
The answer is that the temperature in the water after Raul added the ice cubes is 72.3 + (-39.1)= 33.2
Answer:
The temperature of the water (in degrees Fahrenheit) after Raul added the ice cubes is 72.3 + (-39.1).

Tammy takes a taxi home from the airport. The taxi fare is $2.10 per mile, and she gives the driver a tip of $5. Tammy pays a total of $49.10. Which equation can be used to determine the distance between Tammy's home and the airport?
Answer:
Tammy home is 21 miles away from the airport.
Step-by-step explanation:
I tried out different numbers and either had to go up or go down. You'll have to make sure the decimal ends with .10 because she tipped the driver $5 and no change. 2.10 x 21 = 44.1 plus the $5 tip it would be $49.10

8 - 1/3x=16
help meee
Answer:
- 24
Step-by-step explanation:
Step 1:
8 - 1/3x = 16 Equation
Step 2:
- 1/3x = 8 Subtract 8 on both sides
Step 3:
x = 8 ÷ - 1/3 Divide
Step 4:
x = 8 × - 3 Multiply
Answer:
x = - 24
Hope This Helps :)
The solution to the equation 8 - (1/3)x = 16 is x = -24.
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Given equation 8 - (1/3)x = 16
1. Begin by isolating the term with the variable, (1/3)x,
by subtracting 8 from both sides of the equation:
8 - 8 - (1/3)x = 16 - 8
-(1/3)x = 8
2. Next, multiply both sides of the equation by -3 to eliminate the fraction:
-3 * (-(1/3)x) = -3 * 8
x = -24
Therefore, the solution is x = -24.

Find a common multiple between 30 and 42 that is bigger than them.
(Note: I'm not finding the LCM I just need a multiple bigger than them)
Answer:
210
Step-by-step explanation:
GCF(30,42) = 6
LCM(30,42) = ( 30 × 42) / 6
LCM(30,42) = 1260 / 6
LCM(30,42) = 210

Answer:
read down bellow ------->
Step-by-step explanation:
There is a lengthier way of dividing fractions and it could be said to be a "more correct" method. It involves the use of equivalent fractions to make the denominators of both fractions the same. This is the correct way since, strictly speaking you can’t divide apples by oranges in the same way as you can’t divide fifths by fourths.
now lets go ahead and do it step by step and lets just hope you get it its pretty easy :)
step1.Find a common denominator and convert each fraction to its equivalent value 4/5➗2/3= 12/15 ➗ 10/15step2: Since the denominators are now the same we can divide the numerators 12/15 ➗ 10/15 = 12/10step3: Simplify the fraction 12/10 = 1 1/5HOPE YOU GET IT NOW ! :3An annual pass to a park costs $120. Use a percent model to find 25% of the full price of the annual pass. 25% of the full price is _____
Answer:
$30 is 25% of $120
25% of the full price of the annual pass is $30.
Given that, an annual pass to a park costs $120.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
We need to find 25% of the full price of the annual pass
Here, 25% of 120
= 25/100 × 120
= 0.25 × 120
= $30
Therefore, 25% of the full price of the annual pass is $30.

Joe sells and ships peanuts for $1.25 per pound plus a shipping fee. One package has a shipping fee of $4.95 and a total cost of $11.20. Using the equation 1.25x + 4.95 = 1.20 solve for x to find the amount of pounds of peanuts Joe shipped.
Answer:
x = 5
Step-by-step explanation:
1.25x + 4.95 = 11.20
- 4.95 -4.95
1.25x = 6.25

Which of the following pairs of base and height produces the greatest area? All measurements are in centimeters.
a) b = 4, h = 3.5
b) b = 0.8, h = 20
c) b = 6, h = 2.25
d) b = 10, h = 1.4
The greatest area can be using the measurement b = 0.8, h = 20.
What is area?The area is the region bounded by the shape of an object. The space covered by the figure or any two-dimensional geometric shape, in a plane, is the area of the shape.
For the greatest area we can use the measurement:
a) b = 4, h = 3.5
area= 4*3.5=14
b) b = 0.8, h = 20
area= 0.8*20 =16
c) b = 6, h = 2.25
area= 2.25*6 = 13.5
d) b = 10, h = 1.4
area= 10*1.4=14
whether we take area of any figure the greatest area can be possible using the measurement b = 0.8, h = 20..

3 (m - 1) = 5m + 3 - 2m just solve it plz
dont answer if u dont know >:(
Answer:
No solution
Step-by-step explanation:
To solve the equation, we would have to find the value of m that would make the equality true.
3(m - 1) = 5m + 3 - 2m
Distribute the 3 on the left side.
3m - 3 = 5m + 3 - 2m
Combine like terms on right side.
3m - 3 = 3m + 3
Add 3 to both sides.
3m = 3m + 6
Subtract 3m from both sides.
0 = 6
Since 0 does not equal 6, there would be no solution to the equation, since no value of m would make 0 = 6 true.
