Answer:
-12.6
Step-by-step explanation:
To evaluate the given expression
-2.6+(−2.9)+(−7.1, first we will open out the brackets and multiply the signs. Before that, we must take note of the following sign operations
-×- = +
-×+ = -
+×- = -
+×+ = +
The equation above becomes;
-2.6-2.9-7.1 (all the signs are now minus since the product of plus and minus sign gives a minus sign)
(-2.6-2.9)-7.1
= -5.5-7.1
= -12.6
Since all the values in the equation are negative values, our resulting answer will be a negative value.

Drag and drop the word SUM to the correct value on the number line.
Answer:
-1
Step-by-step explanation:
We are given that an expression
[tex]\frac{5}{6}-\frac{11}{6}[/tex]
We have to find the correct value of given expression on the number line.
[tex]\frac{11}{6}=1\frac{5}{6}[/tex]
[tex]\frac{5}{6}-\frac{11}{6}[/tex]
[tex]\frac{5-11}{6}=\frac{-6}{6}[/tex]
[tex]\frac{5}{6}-\frac{11}{6}=-1[/tex]
[tex]\frac{5}{6}+(-1\frac{5}{6})[/tex]
When an integer positive and other integer negative and add them .If negative integer is greater and positive integer is small then we go from left to right.
We go [tex]\frac{5}{6}[/tex] step from [tex]-1\frac{5}{6}[/tex]towards right then we reach at [tex]{-1}[/tex].
Hence, -1 is the correct value of given expression.

To find the difference between (6d+5) and (2-3d), distribute the negative sign and combine like terms to get 9d + 3.
Explanation:To find the difference between (6d+5) and (2-3d), we first distribute the negative sign to the terms inside the second parentheses. This gives us:
(6d+5) - (2-3d) = 6d+5 - 2 + 3d
Next, we combine like terms by adding the coefficients of d:
(6d + 3d) + (5 - 2) = 9d + 3
So, the difference between (6d+5) and (2-3d) is 9d + 3.

Helppppp! After 2 1/4 h, a chainsaw has used 2 13/16 gal of fuel.
How many gallons of fuel did the chainsaw use each hour?
Enter your answer as a mixed number in simplest form.
Answer:
[tex]1\frac{1}{4}[/tex]gallon/hour
Step-by-step explanation:
After [tex]2\frac{1}{4}[/tex] hour a chainsaw has used [tex]2\frac{13}{16}[/tex] gallons of fuel.
[tex]2\frac{1}{4}[/tex] hours = [tex]\frac{9}{4}[/tex] hours
[tex]2\frac{13}{16}[/tex] gallons = [tex]\frac{45}{16}[/tex] = 2.8125 gallons
The chainsaw used fuel after [tex]\frac{9}{4}[/tex] hours = [tex]\frac{45}{16}[/tex] gallons
The chainsaw used fuel in 1 hour = [tex]\frac{\frac{45}{16}}{\frac{9}{4}}[/tex]
= [tex]\frac{45}{16}[/tex] ÷ [tex]\frac{9}{4}[/tex]
= [tex]\frac{45}{16}[/tex] × [tex]\frac{4}{9}[/tex]
= [tex]\frac{180}{144}[/tex]
= [tex]\frac{90}{72}[/tex]
= [tex]\frac{30}{24}[/tex]
= [tex]\frac{15}{12}[/tex]
= [tex]\frac{5}{4}[/tex]

Chainsaw used [tex]1\frac{1}{4}[/tex] gallons of fuel in each hour

Explain how to model the multiplication of 3 and ‒4 on a number line
First, start at zero. Now, because we are multiplying -4 by 3, we will jump over by 4 to the left ; 3 times on the number line. We should reach -12, and if we check our work, 3 x -4 = -12.
Final answer:
To model the multiplication of 3 and -4 on a number line, start at zero and make three moves to the left by 4 units, ending up at -12. This demonstrates the rule that multiplying numbers with opposite signs results in a negative product.
Explanation:
To model the multiplication of 3 and -4 on a number line, you can follow these steps:
Start at zero on the number line.
Since you are multipling a positive number by a negative number, you will move in the negative direction (to the left).
Make three moves (corresponding to multiplying by 3), each 4 units to the left. This represents adding -4 three times.
Where you end up on the number line is the product of 3 and -4, which is -12.
This method of multiplication on a number line illustrates the rule that when two numbers multiplied have opposite signs, the answer has a negative sign, such as in the example ( -4) x 3 = -12.

Gali found that she can drive 140 miles in 3 hours, including rest stops, or interstate highways. How long would it take her to drive the interstates from Cleveland, Ohio to Washington, D.C. which is 350 miles?
It would take Gali approximately 7.5 hours to drive from Cleveland, Ohio, to Washington, D.C. on the interstate highways.
To find Gali's average driving speed, we can divide the distance she can travel by the time it takes her:
140 miles / 3 hours = 46.67 miles per hour (approx).
Now that we know her average driving speed, we can calculate the time it would take her to drive 350 miles from Cleveland to Washington, D.C.
Time = Distance / Speed
Time = 350 miles / 46.67 miles per hour
Time ≈ 7.5 hours

a certain medicine is given an amount proportional to a patient's body weight. suppose a patient weight 132 pounds requires 143 milligrams of medicine. what is the amount of medicine required by a patient weighing 156 pounds?
To solve this problem, we set up a proportion based on the provided information: 132 pounds correlates to 143 milligrams. We then use cross multiplication to find the required dosage for the patient with the weight of 156 pounds, which results to about 169.3 milligrams.
Explanation:The method to solve this issue is to use the concept of proportionality. First, we set up a proportion based on the given information: 132 pounds (patient weight) correlates to 143 milligrams (medicine dosage). Secondly, we could use cross multiplication to find the unknown medicine dosage for the patient weighting 156 pounds. Here's the mathematical process:
Set up the proportion: 132/143 = 156/x Cross multiply: 132*x = 143*156 Solve the equation: x = (143*156)/132
Carrying out the multiplication and division should result in x ≈ 169.3 milligrams. So a patient weighing 156 pounds would require approximately 169.3 milligrams of the medicine.
