Part (a)

Answer:  ad = bc

-------------------------

Explanation:

In the equation a/b = c/d, we have b and d in the denominator.

If we multiply both sides by bd, then the denominators will cancel. The expression bd is the same as bd/1.

As a similar example, consider the equation

a/b = 12

if we multiply both sides by b, then we clear out the denominator to end up with a = 12b

As another example, let's consider

a/b = c

Multiplying both sides by b leads to

a = bc

The same idea applies with the denominator d as well.

When going from a/b = c/d to ad = bc, your textbook may refer to this process as "cross multiplication".

=================================================

Part (b)

Answer:  bd is the product of the denominators

-------------------------

Explanation:

Often in math, writing two variables next to each other represents multiplication.

bd is the same as b*d which means "b times d". The term "product" is the result of multiplying two or more values.

b and d are both in the denominator of each fraction, so bd represents the product of the denominators.

Answer:

Step-by-step explanation:

r:=interest rate =7%

p = unknown

Principle + interest = 4280

t = 1 year

Formula

Total = p*r*t + p

4280 = p*(1 + r*t)

4280 = p*(1 + 7/100 * 1)

4280 = p (1.07)

4280 / 1.07 = p

P = 4000

===================

What this means is that if you loan out 4000 dollars for a year at 7%, you will get 280 dollars in return (plus of course your 4000). However in this day and age, try getting 7%.

The 100 dollar problem is the same thing. This time you have P and you want the total.

Total = p(1 + r*t)

Total = 100 (1 + 7/100 * 1

Total = 100 ( 1 + 0.07)

Total = 107

So the principle is given and the value of the investment after 1 year is 107 dollars.

Answer:The sum of the angle measurements in a triangle is 180°. If e, f, and g are the measurements of angles E, F, and G, respectively, e + f + g = 180°.

Angle E is a right angle, so e is 90°. From the given information, f is 30°. Substitute the values of e and f in the equation to solve for g : 90° + 30° + g = 180°.

Answer:

Okay I'll try to answer this from what you're trying to ask:) and good luck on your test!

Step-by-step explanation:

So to check that 4(n-2) is equal to 4n+8, you would do the distributive property. Now the distributive property is when you take the number outside of the parentheses (in this case 4) and multipy it by what is inside the parentheses (n and 2). With that, you'll get 4 times n which is 4n and 4 times 2 which is 8, combine them and voila! MAKE SURE YOU LOOK AT THE SIGN INSIDE OF THE PARENTHESES

4(n+2)

=4*n + 2*4

=4n+8

Here's another example

3(n-5)

=3*n - 3*5

=3n-15

Hope that helps:)

Answer:

16/15 or 1 1/15

Step-by-step explanation:

Subsitute p for 4/5

12/15+4/15

=16/15

Answer:

He pays 31.99

He saved $8

Step-by-step explanation:

Find the original price (39.99)

Get the the discount (20%)

Calculate the savings: 20% of $39.99 = $8 (rounded)

Subtract the savings from the original price to get the sale price: $39.99 - $8 = $31.99

Answer:

He pays: 31.99

Step-by-step explanation:

Original price: 39.99

Discout: 20%

Savings: 20% of 39.99= 7.998

7.998 rounded: 8$

Savings minus OG price: 39.99-8

= 31.99

Answer:

a. Negation of ∃x ∀y(P(x,y) → Q(x,y)) = ∀x  ∃y P(x,y)  ∧ ¬Q(x,y) ]

b. Negation of ∃x ∀y(P(x,y) → P(y,x)) = ∀x ∃y  [ ¬P(x,y) ∨ ¬P(y,x) ] ∧ [P(x,y) ∨ P(y,x)]

c. Negation of ∃x ∃y P(x,y) ∧ ∀x ∀y Q(x,y) = ∀x ∀y ¬ [P(x,y)]  ∨ ∃x ∃y ¬ [Q(x,y)]

Step-by-step explanation:

a.∃x ∀y(P(x,y) → Q(x,y))

Negation = ¬ [ ∃x ∀y(P(x,y) → Q(x,y)) ]

                = ∀x  ¬ [ ∀y(P(x,y) → Q(x,y)) ]

                = ∀x  ∃y ¬ [ (P(x,y) → Q(x,y)) ]

                = ∀x  ∃y ¬ [  ¬P(x,y)  ∨ Q(x,y) ]

                = ∀x  ∃y P(x,y)  ∧ ¬Q(x,y) ]

Negation of ∃x ∀y(P(x,y) → Q(x,y)) = ∀x  ∃y P(x,y)  ∧ ¬Q(x,y) ]

b. ∃x ∀y(P(x,y) → P(y,x))

Negation = ¬ [ ∃x ∀y(P(x,y) → P(y,x)) ]

               = ∀x ¬ [ ∀y(P(x,y) → P(y,x)) ]

               = ∀x ∃y ¬ [ (P(x,y) → P(y,x)) ]

               = ∀x ∃y ¬ [ ( P(x,y) ∧ P(y,x) ) ∨ ( ¬P(x,y) ∧ ¬P(y,x) )]

               = ∀x ∃y ¬ [ P(x,y) ∧ P(y,x) ] ∧ ¬[ ¬P(x,y) ∧ ¬P(y,x) ]

               = ∀x ∃y  [ ¬P(x,y) ∨ ¬P(y,x) ] ∧ [ P(x,y) ∨ P(y,x) ]

∴ we get

Negation of ∃x ∀y(P(x,y) → P(y,x)) = ∀x ∃y  [ ¬P(x,y) ∨ ¬P(y,x) ] ∧ [P(x,y) ∨ P(y,x)]

c. ∃x ∃y P(x,y) ∧ ∀x ∀y Q(x,y)

Negation = ¬ [ ∃x ∃y P(x,y) ∧ ∀x ∀y Q(x,y) ]

                = ¬ [ ∃x ∃y P(x,y) ]  ∨ ¬ [ ∀x ∀y Q(x,y) ]

                = ∀x¬ [  ∃y P(x,y) ]  ∨ ∃x ¬ [ ∀y Q(x,y) ]

                = ∀x ∀y ¬ [ P(x,y) ]  ∨ ∃x ∃y ¬ [ Q(x,y) ]

∴ we get

Negation of ∃x ∃y P(x,y) ∧ ∀x ∀y Q(x,y) = ∀x ∀y ¬ [ P(x,y) ]  ∨ ∃x ∃y ¬ [ Q(x,y) ]

Answer:

y = 2.5x + 0

Step-by-step explanation:

Use the slope formula and slope-intercept form y = mx + b to find the equation.

Answer:

w = 18 is the solution

The equation for this problem is 6w - 28 + w = 98

w stands for width

Step-by-step explanation:

7x - 28 = 98 Collect like terms

7w = 98 +28 Move the constant to the right hand side and change its sign

7w = 126 Add the numbers

w = 18 Divide both sides of the equation by 7

Answer:

I believe its C, have a good day!

Step-by-step explanation:

A = $575.00

I = A - P = $75.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year.

Solving our equation:

A = 500(1 + (0.03 × 5)) = 575

A = $575.00

The total amount accrued, principal plus interest, from simple interest on a principal of $500.00 at a rate of 3% per year for 5 years is $575.00.

Answer:

20

Step-by-step explanation:

if their ages total is 60 and gabrielle's is two times mikhail's age, that means that Mikhail would be twenty because their age times 2 would be 40 and 40 plus 20 is 60.

Answer:

A) g = 2m OR g -2m = 0

B) g + m = 60

Multiplying A) by -1

A) -g + 2m = 0 then adding this to B)

B) g + m = 60

3m = 60

Mikhail’s age = 20

Gabrielle's age = 40

Answer:

78 x 10² or 7.8 x 10³

Step-by-step explanation:

you have to get the exponents the same before you can subtract the coefficients

8 x 10³ = 80 x 10²

80 x 10² - 1.7 x 10² = 78 x 10² or 7.8 x 10³

Answer:

A = 44.5 square feet

Step-by-step explanation:

you can separate the 5' x 5' square on top from the trapezoid on the bottom

A(square) = s² = 5² = 25

A(trapezoid) = 1/2h·(sum of 2 bases)

                    = 1/2 (6) (5 + 8)

                     = 3(13)

                      = 39/2 = 19.5

Area of total shape = 25 + 19.5 = 44.5
