The sum of the three numbers is 180. The first number is 10 more than the mean of the three numbers and the second number is 4 l

4vir4ik [10]

Answer:

The third number (c) is 54.

The other ones are 70 and 56.

Step-by-step explanation:

We have 3 numbers, let's call them a, b and c.

We know that the sum of the three numbers is 180, thus:

$a+b+c=180$

We also know that the first number is 10 more than the mean of the three numbers (Note: the mean is the sum of the numbers divided by the number of numbers). Thus:

$a=\frac{a+b+c}{3} +10\\a=\frac{a+b+c+30}{3} \\3a=a+b+c+30\\2a=b+c+30$

Finally the second number is 4 less than the mean:

$b=\frac{a+b+c}{3}-4\\b=\frac{a+b+c-12}{3} \\3b=a+b+c-12\\2b=a+c-12$

Now we have our set of equations and we can proceed to solve them:

$a+b+c=180\\2a=b+c+30\\2b=a+c-12$

Solving for a in our first equation we have: $a=180-b-c$ and substituting this in our second equation we have:

$2a=b+c+30\\2(180-b-c)=b+c+30\\360-2b-2c=b+c+30\\330=3b+3c\\110=b+c$

Now taking this last result into our first equation we have:

$a+b+c=180\\a+(b+c)=180\\a+110=180\\a=70$

Now we are going to solve for b in our second equation and substitute this in our third equation: $b= 180-a-c$

$2b=a+c-12\\2(180-a-c)=a+c-12\\360-2a-2c=a+c-12\\372=3a+3c\\124=a+c$

But we know that a =70, so we can substitute it in our last line:

$124=a+c\\124=70+c\\54=c$

Now we just need to find b and we can use our first original equation to do this:

$a+b+c=180\\70+b+54=180\\124+b=180\\b=180-124\\b=56$

Use the distributive property of multiplication to find 6×24. Hint: 24= 4+20.

Marina86 [1]

Answer:

see explanation

Step-by-step explanation:

6 × 24 ← replace 24 by 4 + 20

= 6(4 + 20) ← multiply each term in the parenthesis by 6

= 24 + 120

= 124

Identify the quadrant where each point is located. (-5,2) (5,-5) (2,-5) (-4,-5)

Tanzania [10]

(-5,2) is located in the II quadrant because the x is negative and the y is positive.

(5,-5) is located in the IV quadrant because the x is positive and the y is negative.

(2,-5) is also located in the IV quadrant because the x is positive and the y is negative.

(-4,-5) is located in the III quadrant because both x and y are negative.
