The sum of 20 and a number, m

Answer: Place the compass point at A i think

Step-by-step explanation: if a and b go toghter than its not c so i would be ertier since b is closer it is not b so the answer is a i think

B) Place the compass point at B

Answer:

The simplified expression is given as

[tex]8x^2y^4(17x^2-2)[/tex]

Step-by-step explanation:

step one:

Given the expression

[tex]x^2y^4(x^2 - 16) - 9y^4(x^4 - 16)[/tex]

step two:

First, let us open the bracket we have

[tex]x^2y^4(x^2 - 16) - 9y^4(x^4 - 16)\\\\x^4y^4-16x^2y^4-9x^4y^4+144x^4y^4\\\\[/tex]

step three:

collect like terms we have

[tex]x^4y^4-16x^2y^4-9x^4y^4+144x^4y^4\\\\x^4y^4-9x^4y^4+144x^4y^4-16x^2y^4\\\\-8x^4y^4+144x^4y^4-16x^2y^4\\\\136x^4y^4-16x^2y^4\\\\\\[/tex]

step four:

we can now factor out [tex]8x^2y^4[/tex]we have

[tex]8x^2y^4(17x^2-2)[/tex]

Answer:

p = (2h-W)/-3

Step-by-step explanation:

2h - W = -3p

divide both sides by -3

(2h-W)/-3 = p

The value of p is w/3 - 2h/3.

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S

Given:

2h = W-3p

For p move w

2h - w = -3p

Now,  divide both side by 3

2h/3 - w/3 = -3p/3

2h/3 - w/3 = -p

p= w/3 - 2h/3

Hence, the value of p is w/3 - 2h/3.

Step-by-step explanation:

The account balance after transactions will be $90.

What is Addition?

A process of combining two or more numbers is called addition.

Given that;

The account started with a balance of $125 and

deposit $50,

deposit $35

withdrawal -$70

withdrawal -$50

Now,

Deposit in account means to add the amount and withdrawal means to remove money from account.

Since, The account started with a balance of $125.

After deposit $50,

The account balance = $125 + $50 = $175

Again after deposit $35;

The account balance = $175 + $35 = $210

After withdrawal -$70;

The account balance = $210 - $70 = $140

Again after withdrawal -$50;

The account balance = $140 - $50 = $90

Thus, The account balance after transactions will be $90.

Answer:

Slope is 1/4 (0.25) while y-intercept is 5

Step-by-step explanation:

Here, we are interested in getting the y intercept and slope of the line joining the given points.

We can get the slope by using any two points

Let’s say (4,6) and (12,8)

Mathematically; slope

= (y2-y1)/(x2-x1) = (8-6)/(12-4) = 2/8 = 1/4 = 0.25

To get the y-intercept, we proceed

kindly recall that the equation of a straight line is;

y = mx + c

where m is the slope and c is the y-intercept

Let’s take any of the points (28,12)

Thus:

12 = 0.25(28) + c

12 = 7 + c

c = 12-7

c = 5

Answer:

277

Step-by-step explanation:

14^2+5(14)+11=

196+70+11=

277

Start by substituting 14 in for x everywhere that x appears in the problem.

So we have (14)² + 5(14) + 11.

Remember that PEMDAS tells you to deal

with your exponents before multiplying.

So you must square the 14 to get 196.

So we have 196 + 5(14) + 11.

Now multiply 5(14) to get 70.

So we have 196 + 70 + 11.

Now we can simply add to get 277.

Answer:

x=1

Step-by-step explanation:

Answer:x=30

Step-by-step explanation:

So first you have to find x so add all your sides together:

Equation: 45+2x+0.5x+x=150

Combine like terms: 45+3.5x=150

Subtract 45 from -45 -45

both sides: 3.5x=105

Then divide by 3.5: x=30

Now that you have your x substitute it in:

2(30)=60

0.5(30)=15

and the last one is x=30

And there you have all your sides! If you wanna check it just add up all the sides and it should equal 150.

Answer:100

Step-by-step explanation:

Expand

x = 150 - 0.5x

Add 0.5x to both sides

x + 0.5x = 150

Simplify x + 0.5x to 1.5x

1.5x = 150

Divide both sides by 1.5

x = 150/1.5

Simplify 150/1.5 to 100

x = 100

Answer:

q= -ck+dp/

-k+d

Step-by-step explanation:

Step 1:

Multiply both sides by p.

dp=ck−kq+pq

Step 2:

Flip the equation.

ck−kq+pq=dp

Step 3:

Add -ck to both sides.

−kq+pq=−ck+dp

Step 4:

Factor out variable q.

q(−k+p)=−ck+dp

Step 5:

Divide both sides by -k+p.

q= -ck+dp/
