Mark plans to save 2.50 each week until he saves 75.00.He uses this equation to represent the number of weeks

Answer:

The majority of theorems in mathematics take the form of compound statements. These statements are called conditional and biconditional statements.

The conditional statement from the sentence above is:

If x is an engineer then x is resourceful.

Put in a mathematical form we can refer to the Implication as:

If Xe then R. Or

Xe implies R. Or

Xe if R.

The Hypothesis is stated as

Xe ⇒ R

The statement  Xe in an implication Xe ⇒ R is called its hypothesis, premise, or antecedent, and R  the conclusion or consequence.

Implications are critical in expressing a logical argument. If an implication is found to be true, then the consequences must be as well when the hypothesis satisfied. This is why is also referred to as a conditional statement.

Brainiest plz?   :)

Answer: The number is 7

Step-by-step explanation:

Let x be the [number]

Rephrase the expression

2 times a number is increased by 4, it is the same as 25 decreased by the number

2x+4=25-x

Calculate

Given

2x+4=25-x

Add x on both sides

2x+4+x=25-x+x

3x+4=25

Subtract 4 on both sides

3x+4-4=25-4

3x=21

Divide 3 on both sides

3x/3=21/3

x=7

Hope this helps!! :)

Answer:

7.8

0.2

Step-by-step explanation:

2 is in the ones place, to get to six you need the value of 2 in the tenths place (0.2)

2+5.8 is 7.8 (add the ones places together to get 7)

0.2+5.8=6 (add in the tenths place)

Answer:

BD = 5 1/3

Step-by-step explanation:

Triangle ABD and ACB are similar with angle A = angle A, angle ABD = ACB. Similar by AA. AB:AC = 6:9, AD:AB = 4:6. This means that the ratio of triangle ABD : ACB is 1 : 1.5. Because of this, since BD corresponds to BC, then BD : 8 = 1 : 1.5, and BD = 8 divided by 1.5, so BD = 5 1/3

Hope this helped :)

Answer:

b=2a+3c−6

Step-by-step explanation:

Let's solve for b.

4a+6c−2b=12

Step 1: Add -4a to both sides.

4a−2b+6c+−4a=12+−4a

−2b+6c=−4a+12

Step 2: Add -6c to both sides.

−2b+6c+−6c=−4a+12+−6c

−2b=−4a−6c+12

Step 3: Divide both sides by -2.

−2b

−2

=

−4a−6c+12

−2

b=2a+3c−6

Answer:

b=2a+3c−6

Answer:

Step-by-step explanation:

$48.36 minus 15 percent is $41.10. If you're tipping the waitress 25 percent from that price, then it would be $51.38. If you're tipping the waitress 25 percent from the original price, it would be $60.45.

Answer:

x = 104 degrees

y = 76 degrees

z = 104 degrees

quadrilateral have to add up all of their interior angles to 360 degrees.

x and c are  opposite interior angles.  after finding that you have to add those 2 together (208) and subtract that from 360. You should get 152. However andgle B (angle y) and angle D are also opposite interiors so you divide 152 by 2 and get 76 degrees.

Also a straight line is 180 degrees so you subtract the degrees of D by 100 to get angle z.

Answer:

m∡x = 104°

m∡y = 76°

m∡z = 104°

Step-by-step explanation:

m∡A ≅ m∡C

m∡B ≅ m∡D

to find m∡B:  2(104) + 2y = 360

                       208 + 2y = 360

                       2y = 152

                        y = 76

m∡z:  180° - 76° = 104°

Answer:

2(x - 5)(x + 4)

Step-by-step explanation:

Given

- 40 + 2x² - 2x , that is

2x² - 2x - 40 ← factor out 2 from each term

= 2(x² - x - 20) ← factorise the quadratic

Consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (- 1)

The factors are - 5 and + 4 , since

- 5 × 4 = - 20 and - 5 + 4 = - 1 , then

x² - x - 20 = (x - 5)(x + 4) and

2x² - 2x - 40 = 2(x - 5)(x + 4) ← in factored form

Answer:

f(50) = 109.44943 feet

Step-by-step explanation:

Modeling

The model of a situation where the skid distance f is measured against the car speed x can be expressed as:

[tex]f(x) = 0.0425x^2 + 0.07381x - 0.49107[/tex]

Using this equation, we can predict the skid distance for a car that is driving at x=50 mph by substituting in the equation of the model:

[tex]f(50) = 0.0425*50^2 + 0.07381*50 - 0.49107[/tex]

[tex]f(50) = 106.25 + 3.6905 - 0.49107[/tex]

f(50) = 109.44943 feet

Answer:

question 1 = 37 covers , 535 dollars

question 2 = 32 covers , 460 dollars

Expression = 69 covers , 995 dollars

Step-by-step explanation:

You would take the number of covers and multiply it by 15 because 15 dollars is how much they sold each cover for.

and then for the expression wasnt sure what to do but from what i could see you added up the totals.

Hope this helped him :)

Noah's number is 15

S=15

Answer:

1ft≤h≤25ft

Step-by-step explanation:

The area of a rectangle is expressed as;

Area = Length * height

A = Lh

If the area of a rectangle is at most 400 square centimeter, this is expressed as;

A ≤400

≤ means at most that is the area of the rectangle cannot be greater than 400

Substitute the given value into the inequality expression

Lh ≤ 400

Given

L = 16

16h ≤ 400

Divide both sides by 16

16h/16 ≤ 400/16

h ≤ 400/16

h ≤ 25

Hence the possible values of the height are with the range 1ft≤h≤25ft since we cannot have a negative value for the dimension
