Answers
Answer:
C.
Step-by-step explanation:
The answer is C, as as any value of m will make the equation true.
Such as if we used 2 as a substite value for m.
[tex]-6(2)-6+8(2)=-5+2(2)-1[/tex]
Lets simplify both equations:
[tex]-6(2)-6+8(2)=-2[/tex]
[tex]-5+2(2)-1=-2[/tex]
Now, if you want, you can also use any other value for m, but that is basically how I got C. If they equations didn't have the same answer, then it would be B. If it only worked for 2 numbers, then it would be A. Now, I tried this equation again with -3=m, but I still ended up with the same answers. So it wouldn't have been D.
Beatrice makes a jar of dry soup mix. The ingredients are:
. 1 3/4 = 7/4 cups uncooked rice . 1/3 cup beef bouillon
. 1/2 cup dry lentils . 1/4 cup dried onion flakes
. 1 2/3 = 5/3 cups uncooked pasta . 1/2 cup dried peas
Answer the questions to find out how much soup the recipe makes.
The sum 7/4 + 1/2 + 5/3 + 1/3 + 1/4 + 1/2 gives the amount of mix.
1. Which property could you use to change the order of the addends?
2. Which property could you use to change the grouping of the addends?
3. Use these properties to rewrite the number sentence 7/4 + 1/2 + 5/3 + 1/3 + 1/4 + 1/2 in a way that makes the addition easier. Explain how your changes simplify the addition.
4. Simplify your sum to find the total amount of soup mix. Show your work.
Answers
Answer:
4 8/12
Step-by-step explanation:
7/4 = 1 3/4
2/4 = 1/2
4/12 = 1/3
1/4 = 1/4
20/12 = 1 2/3
2/4 = 1/2
multiply the numerator and the denominator by 4 because 12 is a factor of 4 and 3
do that to all of the fractions (except the one that already has 12 as the denominator)
the add all of them together because they all have the same denominator
Jane drives at a constant rate of 45 miles per hour for 4 hours. How far will she have traveled in that time?
A. 110 mi.
B. 160 mi.
C. 180 mi.
D. 220 mi.
Answers
Answer:
180 miles per hour. 45*4 to get the answer.
Step-by-step explanation:
I hope this helps you :)
Jane is driving 45 miles per hour, so for every hour she has driven for 45 miles. Now she has driven for four hours. So, you must multiply 45×4 to get 180 miles.
Therefore, your answer is C. 180 mi.

A certain computer can do 250,000 calculations per minute. How many calculations can it do in 0.15 seconds? 37,500
You will get brainliest if you get this question correct. I really need the right answer.
Answers
Answer:
625
Step-by-step explanation:
1 minute= 60 second= 60.00 seconds
-------------------------------------
From the information given, we can make this equation:
[tex]\frac{0.15}{60.00} =\frac{x}{250,000}[/tex]
Now all we need to do to find the answer is to solve for x.
-------------------------------------
Cross Multiplication:
[tex]\frac{0.15}{60.00} =\frac{x}{250,000}[/tex]
0.15*250,000=60x
37,500=60x
÷60 ÷60
625=x
x=625
In conclusion:
The computer can do 625 calculations in 0.15 seconds.

Cody can walk 1/3 of a mile in 1/6 of an hour. How many miles can he walk in 2 1/3 hours if he continues at the same pace?
Do not enter as a mixed number or a decimal, use an improper fraction.
Answers
Answer: 14/3 miles
Step-by-step explanation: Miles divided by hours gives speed
1/3÷1/6 = 2 mph
Distance= speed × time
2 1/3 is 7/3 7/3×2 = 14/3
1/3 mile = 1/6 hour
2 1/3 hours can be converted to 7/3 (2x3=6, 6+1 = 7), which can be converted to sixths by multiplying 7 and 3 by 2 (7x2=14, 3x2=6) and getting 14/6.
Since 1/3 of a mile is equivalent to 1/6 of an hour, 14/6 hours is 14/3 because 14x1=14.

(8, 9)Step-by-step explanation:
3 and 5 are vertical angles and are equal as per definition of vertical angles
4x + 6y = 865 and 6 are supplementary angles and sum up to 180 as per definition of supplementary angles
5x + 6y + 86 = 180 ⇒ 5x + 6y = 94Comparing the two equations
6y = 86 - 4x and 6y = 94 - 5x86 - 4x = 94 - 5x5x - 4x = 94 - 86x = 8Finding y
6y = 86 - 8*46y = 86 - 326y = 54y = 9Answer
