x+4=10;x=

I literally dont get it please help

Answer:

Question 1: add 3a + 4a becuase they have the same variables. you should get 7a. Then subtract 10b and 4b because they have the same variables,You should get 6b. The answer is 7a+6b because you can't do anything with those numbers because of their variables and how they are not the same.

Question 2: The answer is x=10. to get the answer move all terms not containing x to the right side of the equation and add as normal.

Question 3: The answer is -5. Steps: move the equation around so there is a 2 on both sides of the equation, should look like this: 2x= -12 +2. Then add -12 +2 = -10. Then divide each term by 2 and simplify, should look like this: 2x/2 = -10/2. Then cancel the comments factor which is 2 should look like this: x = -10/2. After divide x by 1. Then divide -10 by 2 which equals -5.

Question 4: The answer is m=6. First multiply 6x2=12 then multiply that by 2 which should get u 24 then divide 24 by 4 =6

Question 5: sry I dont understand :(

Answer:

1. 7a+6b because 3a+4a=7a and 10b-4b=6b

2. x=10 because you add 3 to the other side to cancel it out and 7+3=10

3. x=6 because

2*m=2m and 2*6=12

24-12=12 and 12/2=6

Step-by-step explanation:

My bad, I did my math wrong. Its -3.

Answer:

-(-5) - 8=

5-8= -3

Step-by-step explanation:

replace the variables with the numbers and solve it like a normal equation

Answer:

1. A, because 4(2)=8. 2 is the x.

2. B, because 2.5 x 4 = 10, which makes sense.

3. B, because 5x is the amount that you want to put into equal parts and the 3 is just being subtracted from the amount of the equal parts from the 5x.

4. C.

Answer:

39

Step-by-step explanation:

2x5=10

10+3=13

13x3=39

Answer:

39

Step-by-step explanation:

First since f=5 , you should get rid of the f

2 * 5 = 10

so now the equation is 3(10+3)

Then you add the numbers in the parentheses

10 + 3 = 13

Then multiply it by 3

3 * 13 = 39

39 is your answer

195 is the answer because you replace x with 10

Step-by-step explanation:

825-630=195

Answer:

195 is da answer

Step-by-step explanation:

3x = 2/5

x = 2/5 · 3

x = 17/5

x = 17/5

or

x = 3.4

Answer: 76

Step-by-step explanation:

well, we know that 15% of the X is 12, so we first use 6 15%, which is 90% 6X12=72. next, we would use 12/3, which is 4. 72+4=76.

Answer:

80

Step-by-step explanation:

12/x = 15/100

cross multiply

1200/15x; 1200/15 =80

x=80

Answer: 50

Step-by-step explanation:

5/9 (f-32) if f = 122 you take 122 and subtract 32 because of order of operations and now you have 5/9 (90) and then you multiply 5/9 times 90 and you get 50

Answer:

19: The difference between the temperature in Fair Banks and Barlow is 3°F

20: -13°F, -10°F, 15°F, 24°F.

Step-by-step explanation:

I'm assuming that by "compare", it means to find the difference between temperatures in question 19. If it means something else, let me know and I'll try and help you find it.

Answer:

for 19 is the difference between the temperature in Fairbanks and Barlow is 3°F and for 20 is -13°F, -10°F, 15°F, 24°F.

it means to find the difference between temperatures in question 19 i guess that helps. 0-o

Step-by-step explanation:

rs=2^2+4^2=20cm

sq root of 20=4.472135955 (round down to how much you like, probably 1dp)

qt=4^2+8^2=80cm

sq root of 80= 8.94427191

for the other pic just do [tex]\sqrt{80}[/tex] takeaway [tex]\sqrt{20}[/tex], which is 4.472135955 and round down to how much u like

not completly sure

Answer:

it is d

Step-by-step explanation:

You can't have more x values than y

Answer:

No.

Step-by-step explanation:

72 times 0.15=10.8

72-10.8=61.2

No. Taylor doesn't have enough.

You could also have done 72 times 0.85, and then you wouldn't have had to minus 10.8 and all those stuff.

Hope this helps!

Step-by-step explanation:

First you tell me what is the question, and then I will try to answer.

Answer: step by step calculation, formula & solved example

problem to find the area for the given values of base b, & height h of triangle in

inches (in), feet ... Learn how we & our partners collect & use data. ... (1/2) x Base

x Height substitute the values = (1/2) x 18 x 12 = 108 cm2. The area of a triangle

Step-by-step explanation: The Pythagorean theorem states that, in a right triangle, the length of the hypotenuse squared equals the sum of the squares of the other two sides or legs of the triangle.  Algebraically, a2+b2=c2.  In your example, the length of the ladder would be the hypotenuse and the distance from the wall would be one of the legs.  So substitute these values into the equation to get: 32+b2=122 or 9+b2=144 and then subtract 9 from both sides to get b2=135.  Therefore b=√135≈11.62.  If your problem requires an exact answer in its most simplified form, please note that √135=3√15.  Hope this helps you

Good Luck

Answer:

Step-by-step explanation:

1.

P(A) = 1/6, P(B) = 1/2

P(A and B) = 1/6*1/2 = 1/12

2.

P(A) = 1/6

P(B) = 1/6

P(A and B) = 1/6*1/6 = 1/36

3.

P(A) = 2/6 = 1/3

P(B) = 1/3

P(A and B) = 1/3*1/3 = 1/9

4.

P(gold) = 4/7 for each

P(2 golds) = 4/7*4/7 = 16/49

5.

Remaining marbles:

P(green) = 2/5
