it should be that

The account which is not the example of the type of savings vehicle is Checking Account. Thus option 3rd is correct.

The three kinds of the saving account are regular deposit, money market, and Certificate of Deposits. There is a difference in all the three types in terms of the accessibility and amount of interest.

The Checking account is the account which carries the day to day transactions of the money. It ensures the easy access to the money. Many of the people generally uses the debit card or the checks to make the purchases.  Thus option 3rd is correct.

Answer:

Density of the material is 5 grams per cubic centimeter.

Step-by-step explanation:

The answer is required to be given in grams per cubic centimeter.

So we should first convert the values to match the units.

Mass is given as 2500 grams so we don't need to change the units.

Volume is given in cubic centimeters. So we don't need to change the units.

Density      = [ Mass of the material / Volume of the Solvent]

                  =2500 grams / 500 cubic centimeters

                  =5 grams per cubic centimeter

Hey there!!

Slope-intercept form :

y = mx + b

m is the slope and b is the y-intercept.

Given equation :

x - 2y = 12

We will have to isolate the y.

... x - 2y = 12

... -2y = x - 12

... y = ( x - 12 ) / -2

... y = x / - 2 + 6

Hence, the slope is -1/2

Hope my answer helps!

This type of relationship is exponential decay

The three consecutive numbers that can be equal to 24 are 7,8,9

7+8+9=24

This is an isosceles triangle. Therefore |AC| = |BC|.

2x = 3x - 5     |subtract 3x from both sides

-x = -5       |change the signs

given -2(x + 1) = 5x + 4 - x ( distribute left side )

-2x - 2 = 4x + 4 ( simplifying both sides )

subtract 4x from both sides

- 6x - 2 = 4 ( add 2 to both sides )

- 6x = 6 ( variable by itself on left side )

divide both sides by - 6

x = [tex]\frac{6}{-6}[/tex] = - 1

as a check, substitute x = - 1 into the equation and if both sides are equal then it is the solution.

left side = - 2(-1 + 1 ) = - 2 × 0 = 0

right side = (5 × - 1) + 4 - (- 1) - 5 + 4 + 1 = 0

hence x = - 1 is the solution

Remark

The slope intercept graph needs a table like the one provided by the graph shown below.

A sample calculation would look like this

y = (2/3)x - 2  Let x = 6 (which is not plotted on the graph).

y = 2/3 * 6 - 2   The 3 will divide into the 6 two times

y = 4 - 2

y = 2

So you would plot this as (6,2)

The way I did this was made everything decimals so .75/.25 and it equals 3

The expression evaluates to -4 when x equals 4.

To evaluate the expression –0.4(3x – 2) + for [tex]\( x = 4 \)[/tex], follow these steps:

1. Substitute the value of [tex]\( x \)[/tex] into the expression.

2. Perform the arithmetic operations according to the order of operations (PEMDAS/BODMAS).

Here's the step-by-step calculation:

Given expression: [tex]\(-0.4(3x - 2) +\)[/tex]

Substitute [tex]\( x = 4 \)[/tex]:

[tex]\(-0.4(3(4) - 2) +\)[/tex]

Now, simplify inside the parentheses first:

[tex]\(-0.4(12 - 2) +\)[/tex]

[tex]\(-0.4(10) +\)[/tex]

Next, multiply [tex]\(-0.4\)[/tex] by [tex]\( 10 \)[/tex]:

[tex]\(-4 +\)[/tex]

Finally, there's no more to compute since there's no other term. So the result is:

[tex]\(-4\)[/tex]

Therefore, the value of the expression [tex]\(-0.4(3x - 2)\)[/tex] when [tex]\( x = 4 \)[/tex] is [tex]\( -4 \)[/tex].

Use the graph to determine the solution of the inequality |x + 1| + 2 > 5.

To graph this , first we make the absolute function alone

|x + 1| + 2 > 5

to make absolute function alone we subtract 2 from both sides

|x + 1|  > 3

x+1 inside the absolute function . so x=-1

From -1, move 3 units to the right and 3 units to the left.

For x>2 , shade the graph to the right

For x< -4, shade the graph to the left

You divide the difference in y-coordinates by the diffrence in x-coordinates. Or whatever the variables are.

Lets say the coordinates of the two points are (a,b) and (c,d). Then:

Rate of change is "rise/run" = (b - d)/(c - a) = (d - b)/(a - c)

Ruben has 6 new books for his collection. This increases his collection by 12%

Let x be the number of books Ruben has before 6 new books added

x + 12% of x = x+6

x + 0.12x = x+6

1.12 x = x+6

Subtract x on both sides

0.12x = 6

Divide by 0.12

x = 50

6 new books are added for his collection

So 50 + 6 = 56

He have 56 books now.

Substitute y = x - 4 to the first equation:

-3x + 4(x - 4) = -20     use disrtibutive property

-3x + (4)(x) + (4)(-4) = -20

-3x + 4x - 16 = -20     add 16 to both sides

x = -4

Substitute the value of x yo the equation y = x - 4:

y = -4 - 4 = -8

Answer:

Correct option is:

a. 6,000 ft²

Step-by-step explanation:

A pavement is 20 ft wide and 100 yd long

1 yd= 3 ft

100 yd = 300 ft

we have to find the area of pavement

Area= Length × Width

       = 300 ft × 20 ft

       = 6000 ft²

Hence, Correct option is:

a. 6,000 ft²

All you have to do is add 25+ 27= 52

The answer is choice C

On the left side we have something in the form a*b+a*c+a*d

On the right side we have something in the form a*(b+c+d)

All together, we have a*b+a*c+a*d = a*(b+c+d), where the letters a,b,c,d are to be replaced with the proper values (0.5, 0.5, 0.3, and 0.2 in that exact order).

The idea of distribution is to multiply the outer value 0.5 by each of the values inside the parenthesis (0.5, 0.3, and 0.2) and add up the products.

Equation C and D that is (0.5⋅0.5)+(0.5⋅0.3)+(0.5⋅0.2)=0.5⋅(0.5+0.3+0.2) and 0+1.015=(50⋅1)+(50⋅0.01)+(50⋅0.005) ​applies the distributive property correctly as defined "multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together".

The distributive law, which states that in elementary algebra, equality is always true, is generalized by the distributive property of binary operations. For instance, in basic mathematics, one has to According to one, addition is distributed more evenly than multiplication. In order to quickly solve expressions, a number is distributed among the numbers in the brackets. When using the distributive property of multiplication, for instance, to resolve the expression 4(2 + 4), we would do so as follows: 4(2 + 4) = (4 × 2) + (4 × 4) = 8 + 16 = 24.

The distributive property states,

A × (B + C) = AB + AC

for equation C

(0.5⋅0.5)+(0.5⋅0.3)+(0.5⋅0.2)=0.5⋅(0.5+0.3+0.2) ​

for equation D,

50+1.015=(50⋅1)+(50⋅0.01)+(50⋅0.005)

According to the definition of the distributive property, which states that "multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together," Equations C and D, which are correctly applied that is (0.5⋅0.5)+(0.5⋅0.3)+(0.5⋅0.2)=0.5⋅(0.5+0.3+0.2) ​and 50+1.015=(50⋅1)+(50⋅0.01)+(50⋅0.005).

22+5d=-56d+32

22+32=54 and -56d+5d=-51d

The answer would be 51d+54

Remark

The steps are the same usually. Remove the brackets and collect like terms on each side of the equal sign.

Solution

22+5d = -8(7d - 4)          Remove the brackets.

22+5d = -56d + 32        Notice the sign change on 32. 2 minus quantities = a plus when multiplied.  Add 56d to both sides.

22 + 5d + 56d = - 56d + 56d + 32

22 + 61d = 32                  Subtract 22 from both sides.

61d = 32 - 22

61d = 10                            Divide by 51

Answer:

The answer is 15 months.

Step-by-step explanation:

p = $500

r = 6.5% or 0.065

A = $543

t = ?

The formula to be used here is :

[tex]A=pe^rt[/tex]

[tex]t=(log(A/p)/log(e))/r[/tex]

Putting the values in formula we get:

[tex]t=(log(543/500)/log(e))/0.065[/tex]

[tex]t=(log(1.086)/log(e))/0.065[/tex]

This gives t = 1.3 years

In months it will be 1 year(12 months) + 3 months = 15 months.

Hence, the answer is 15 months.

Answer:

15 months

Step-by-step explanation:

The two fractions with the common denominator will be 6/ 15 and 4 / 15.

The fraction is defined as the division of the whole part into an equal number of parts.

The two fractions are 2 / 5 and 4 / 15 will be converted into the same common denominator as;-

For fraction 2 / 5 multiply it by 3 in both the numerator and the denominator.

= ( 2  x 3 ) / ( 5  x  3 )

= ( 6 / 15 )

Therefore two fractions with the common denominator will be 6/ 15 and 4 / 15.
