why is math so hard to me but easy for everyone else what division like 31 / 16 is very hard for me ​

Answer: x= -10

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4.5(8−x)+36=102−2.5(3x+24)

(4.5)(8)+(4.5)(−x)+36=102+(−2.5)(3x)+(−2.5)(24)(Distribute)

36+−4.5x+36=102+−7.5x+−60

(−4.5x)+(36+36)=(−7.5x)+(102+−60)(Combine Like Terms)

−4.5x+72=−7.5x+42

−4.5x+72=−7.5x+42

Step 2: Add 7.5x to both sides.

−4.5x+72+7.5x=−7.5x+42+7.5x

3x+72=42

Step 3: Subtract 72 from both sides.

3x+72−72=42−72

3x=−30

Answer:

[tex]\boxed {m = \frac{5}{4}}[/tex]

Step-by-step explanation:

Solve for the value of [tex]m[/tex]:

[tex]-\frac{1}{2} = m - \frac{7}{4}[/tex]

-Switch sides:

[tex]m - \frac{7}{4} = -\frac{1}{2}[/tex]

-Add both sides by [tex]\frac{7}{4}[/tex] and the least common multiple of both [tex]2[/tex] and [tex]4[/tex] is [tex]4[/tex]. So, convert [tex]-\frac{1}{2}[/tex] to a fraction with denominator [tex]4[/tex]:

[tex]m - \frac{7}{4} + \frac{7}{4} = -\frac{1}{2} + \frac{7}{4}[/tex]

[tex]m = -\frac{2}{4} + \frac{7}{4}[/tex]

-Since both [tex]-\frac{2}{4}[/tex] and [tex]\frac{7}{4}[/tex] have the same denominator, then you would add the numerators:

[tex]m = \frac{-2 + 7}{4}[/tex]

[tex]\boxed {m = \frac{5}{4}}[/tex]

Therefore, the value of [tex]m[/tex] is [tex]\frac{5}{4}[/tex].

Answer:

True

Step-by-step explanation:

The left side  22  is equal to the right side  22 , which means that the given statement is always true.

Step-by-step explanation:

If we want to prove that x is equal to seven, we should first solve the equation for x so:

2x + 8 = 5x - 13

We should first add 13 on both sides and subtract 2x from both sides:

2x + 8 + 13 - 2x = 5x - 13 + 13 - 2x

21 = 3x

We can then divide both sides by 3 to get:

x = 7

Answer:

The opposite of 45 is equal to the absolute value of -45.

Absolute value means switching to to a negative if it's a positive and if it's a negative to a positive. For 0, it remains 0 and doesn't switch to a -/+.

Answer:

The opposite of 45 is equal to the absolute value of -45

Answer:

(5x + 7y)(25x² - 35xy + 49y²)

Step-by-step explanation:

125x³ + 343y³ ← is a sum of cubes and factors in general as

a³ + b³ = (a + b)(a² - ab + b³) , thus

125x³ + 243y³

= (5x)³ + (7y)³

= (5x + 7y)((5x)² - 5x(7y) + (7y)² )

= (5x + 7y)(25x² - 35xy + 49y²)

Answer:

x=7

Step-by-step explanation:

4x+3-2x+7=24

We move all terms to the left:

4x+3-2x+7-(24)=0

We add all the numbers together, and all the variables

2x-14=0

We move all terms containing x to the left, all other terms to the right

2x=14

x=14/2

x=7

Answer:

Step-by-step explanation:

Follow PEMDAS

P = parenthasees

E = exponents

M = multiplication

D = division

A = addition

S = subtraction

There are no P or E or M

so divide

-3 = h + 4

then we just subtract four on both sides

h = -7

Answer:

The coordinates of the point P is (0,0)

Step-by-step explanation:

Here, we want to find the coordinates of point P which divides the segment MN in the ratio 2 to 1.

Mathematically, what we shall use here is the internal division formula;

The internal division formula is given as follows;

(x,y) = (nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)

From the question;

x1 = -4

x2 = 2

y1 = 4

y2 = -2

m = 2

n = 1

By substituting, we have;

(1(-4) + 2)2))/(1 + 2) , (1(4) + 2(-2))/(1+2)

= (-4 + 4)/3 , (4-4)/3

= (0,0)

10.8 shots

Step-by-step explanation:

Owen made 60% of the shots he made, and he made 18 shots in total. Therefore, we would take 60% of 18. The answer we get is 10.8, but we can't have a part of a shot.

Answer:

Steps have justified that;

y = $250 + $340x

Step-by-step explanation:

We are told Lewis is saving for a down payment of $8,750 on a house.

Now, the initial amount of money he has saved is $250, while the amount of money he plans on saving every month is $340.

Thus, if x represents the number of months and y represents the total amount of savings. It means that;

For x number of months, he saves; $340x

Now, the initial amount he saved is $250.

This means that the total amount he would have saved after x number of months is;

Total amount saved = Initial savings + Amount saved monthly after x number of months.

Now, total amount saved is denoted as y as given in the question, then we have;

y = $250 + $340x

Answer:

subtraction

y-250=340x

division

y-340=250x
