Answer:4b+5=1+5b

Step-by-step explanation: b= 14b I HOPE THIS HELPS AND HAVE A GOOD DAY!!!! And i really do hope this did help.

The value of expression ab + a² is,  9,37,000

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The expression is,

⇒ ab + a²

And, a = 937, b = 63

Now, Substitute the value of a and b in expression as,

⇒ ab + a²

⇒ 937 × 63 + 937²

⇒ 937 (63 + 937)

⇒ 937 × 1,000

⇒ 9,37,000

Answer: I'm pretty sure it's B

Step-by-step explanation:

Answer:

Do you still need an answer? If so, B!

Step-by-step explanation:

Just by looking at the equation you can see the addition symbols. Since there are also letters, you can use that information to help you solve the answer using the key word: Commutative.

For Example: If Lily needs $40 and she already has $30 how many more dollars does she need?

Answer: m-$30=$40 m=$10

Answer:

$68.24

Step-by-step explanation:

Three friends went to Texas Roadhouse for dinner. The total bill was $76.25. They left the server a 20% tip and the Montgomery County tax rate is 9.5%.

Given data

The total bill was $76.25

tip

=20/100*76.25

=0.2*76.25

=15.25

Tax

=9.5/100*76.25

= 0.095*76.25

=$7.24375

In all the bills is 76.25-15.25+7.24375

=61+7.24375

=$68.24

Answer:

g(12) = 8

Step-by-step explanation:

g(x) = 5/4(12) - 7

g(x) = 5 × 3 - 7

g(x) = 15 - 7

g(x) = 8

i hope this helps :)

Answer:

x=106 degrees

Step-by-step explanation:

I'm going to assume that this is a circle since you didn't give it to me

So you want to add 164 and 90 together and subtract the sum by 360

360-(164+90)=106

So you want to use PEMDAS (order of operations) to solve this

x=106 degrees

1. 32 points 2. 25% 3. 2,100 4. 22% 5. 56.71 6. $300 7. $25 8. The answer for given problem is -2, but Andrew get -21.6 which is wrong.

Answer:

21

Step-by-step explanation:

Answer:

the second one is the better deal

Step-by-step explanation:

Answer:

Part 1)

$170 + $1.21x = $491.86

Part 2)

170 + 1.21x + 491.86

1.21x = 491.86 - 170

1.21 x = 321.86

1.21x/ 1.21 = 321.86/ 1.21

x = 266 units produced

Part 3)

Twice that number of units = 266 x 2 = 532

$170 + ($1.21 x 532) =

$170 + $643.72 = $813.72

Answer:

v= -2

Step-by-step explanation:

Answer:

ano ang pinag kaiba noon kaysa ngayon

Answer:

($19 - $7.25) - $2.75 ÷ (0.50p) ≤ 19

Step-by-step explanation:

First, let's define the variable:

p = pretzel packages

Let's first find out how much money Ben has after buying the notebook.

$19 - $7.25 = $11.75

So, we know that Ben has $11.75 left.

The inequality would be: ($19 - $7.25) - $2.75 ÷ (0.50p) ≤ 19

Answer:

7.) x = 21

8.) y = 6

9.) angle F = 62 degrees

10.) TS = 10

Step-by-step explanation:

5y-2 = 28

5y = 30

y = 6

4x+6 = 90

4x = 84

x = 21

angle F = 90-28

angle F = 62 degrees

3z-8 = z+4

2z = 12

z = 6

TS = z+4 = 10

Answer:

R = - 4

Step-by-step explanation:

5 r + 6r - 2 = - 46

11 r - 2 = - 46

11 r = - 46 + 2

11 r = - 44

r = - 4

Answer:

It’s true

Step-by-step explanation:

Proof by induction

Let the four chosen numbers be x_1, … x_4 and, without loss of generality, let x_1 < x_2, … < x_4.

For x_1 = 1, the smallest possible choice, let x_2 = x_1 + 20 = 21 be the smallest possible choice that has a difference larger than 19. Likewise, x_3 = x_2 + 20 = x_1 + 40 = 41. Then x_4 has to be at least x_3 + 20 = x_1 + 60 = 61 which is out of range.

For the induction, suppose that x_4(n) = x_1(n) + 60 > 60 and therefore x_4(n) can’t be chosen for a given x_1(n). Then incrementing x_1(n+1) = x_1(n) + 1 would require x_4(n+1) to be at least x_1(n) + 1 + 60 = x_4(n) + 1 > 61, so this is out of range as well.

For another induction, suppose that x_4(n) = x_2(n) + 40 > 60 and therefore x_4(n) can’t be chosen for a given x_2(n). Then incrementing x_2(n+1) = x_2(n) + 1 would require x_4(n+1) to be at least x_2(n+1) + 40 = x_4(n) + 1 > 61, so this is out of range as well.

Likewise, for the induction, suppose that x_4(n) = x_3(n) + 20 > 60 and therefore x_4(n) can’t be chosen for a given x_3(n). Then incrementing x_3(n+1) = x_3(n) + 1 would require x_4(n+1) to be at least x_3(n+1) + 20 = x_4(n) + 1 > 61, so this is out of range as well.

Therefore all choices of x_1, x_2, x_3 with differences greater than 19 leaves no choice of x_4 within range with x_4 > x_3 + 19.

Answer:

your awnser should be. 24.75 + 20% = $29.70

so the amount added to her bill is $4.95

Answer:

the bill will be 4.95 more than the original cost without the 20% tip.

Step-by-step explanation:

cost before tip: 4.75

cost after 20% tip: 29.70 or 30.00 (rounded)

Answer:

-30

Step-by-step explanation:

[tex]\frac{N}{-3} -2 =8[/tex] ( Add 2 on both sides)

[tex]\frac{N}{-3} = 10[/tex] ( Multiply by -3 on both sides)

[tex]N = -30[/tex]

Verify:

[tex]\frac{-30}{-3} =10[/tex] (Correct)

Answer:

[tex] \frac{n}{ - 3} - 2 = 8 \\ \frac{n}{ - 3} = 8 + 2 \\ = 10 \\ n = 10 \times - 3 \\ n = - 30[/tex]
