Answer:

1000 to 9999 are all of the 4-digit counting numbers

1 to 9999 gives 9999 counting numbers, but we are leaving out 999 of them

9999-999=9000 counting numbers that are 4-digit numbers

9000-1800=7200 4-digit numbers that are not multiples of 5

Step-by-step explanation:

There are 7,000 four-digit counting numbers that are not multiples of 5.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To find the number of four-digit counting numbers that are not multiples of 5, we need to find the total number of four-digit counting numbers and then subtract the number of four-digit counting numbers that are multiples of 5.

There are 9 choices for the first digit (it cannot be 0, since we are looking at four-digit numbers), and 10 choices for each of the remaining three digits (they can be 0-9).

So, the total number of four-digit counting numbers is:

9 × 10 × 10 × 10

= 9,000

To find the number of four-digit counting numbers that are multiples of 5, we need to consider the last digit.

Since a number is a multiple of 5 if and only if its last digit is 0 or 5, there are 2 choices for the last digit.

The first three digits can be any of the 10 digits, so there are:

10 × 10 × 10 × 2 = 2,000

four-digit counting numbers that are multiples of 5.

Therefore, the number of four-digit counting numbers that are not multiples of 5 is:

9,000 - 2,000 = 7,000

Thus,

There are 7,000 four-digit counting numbers that are not multiples of 5.

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

Explanation:

The point (-3,3) means x = -3 and y = 3 pair up together

So plugging in x = -3 should lead to y = 3 if (-3,3) was a solution

Plug x = -3 into y = -3x to find that

y = -3x

y = -3*(-3)

y = 9

So x = -3 and y = 9 should be the actual pair (not x = -3 and y = 3)

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

Put another way

y = -3x

3 = -3(-3) ... replace x with -3 and y with 3

3 = 9 ... which is false

This shows (x,y) = (-3,3) is not a solution

Answer:

8(-9) and -12-60

1+2/4 and 1-1/4

Step-by-step explanation:

36 ÷ 3 = 12 and 2^2 + 2 = 6 (nah)

-(2/3)^2 = -4/9 and 4/9 (nah)

8(-9) = -72 and -12 - 60 = -72 ( yes)

y= 8 /3 x+ −17 /3

Step-by-step explanation:

Step 1: Add -8x to both sides.

Step 2: Divide both sides by -3.

Have a great day :)

Answer:

y= 17/3 - 8/3x

Step-by-step explanation:

subtract 8x from both sides and get -3y = 17- 8x. Next divide everything by -3 (because it’s the number in front of Y) making it Y= 17/3 -8/3x (were left with big numbers because neither 17 or 8 can be divided by 3)

Answer:

The answer will be 95°

...

Answer:

Sum of angles in a triangle is 180°

So if angle A is 55°

And B is 30°

C is 180 - 55 + 30

= 180 - 85

Angle C = 95°

Answer:

-4 + -4x

Step-by-step explanation:

Simplifying

3x + -7x + -4

Reorder the terms:

-4 + 3x + -7x

Combine like terms: 3x + -7x = -4x

-4 + -4x

Answer:

The simplified equation would be -4x - 4

Step-by-step explanation:

1. Combine the like terms. So it would be -4x-4 because 3-7=-4.

Answer:

The location of point T is [tex]\vec T = (7.5, 2.25)[/tex]. Graph is included at the end of the explanation as attachment.

Step-by-step explanation:

The SQ : QT ratio means that there are 4 units of SQ for each 3 units of QT. Vectorially speaking, we notice that:

[tex]\overrightarrow {SQ} = \frac{4}{7}\cdot \overrightarrow {ST}[/tex] (Eq. 1)

[tex]\overrightarrow{QT} = \frac{3}{7}\cdot \overrightarrow {ST}[/tex] (Eq. 2)

Now, we eliminate [tex]\overrightarrow{ST}[/tex] by equalizing (Eq. 1) and (Eq. 2):

[tex]\frac{7}{3} \cdot \overrightarrow{QT} = \frac{7}{4}\cdot \overrightarrow{SQ}[/tex] (Eq. 3)

From Linear Algebra, we know that:

[tex]\frac{7}{3}\cdot (\vec T - \vec Q) = \frac{7}{4}\cdot (\vec Q-\vec S)[/tex] (Eq. 3b)

And we clear [tex]\vec T[/tex]

[tex]\frac{7}{3}\cdot \vec T -\frac{7}{3}\cdot \vec Q = \frac{7}{4}\cdot \vec Q -\frac{7}{4}\cdot \vec S[/tex]

[tex]\frac{7}{3}\cdot \vec T = \frac{49}{12}\cdot \vec Q - \frac{7}{4}\cdot \vec S[/tex]

[tex]\vec T = \frac{3}{7}\cdot \left(\frac{49}{12}\cdot \vec Q-\frac{7}{4}\cdot \vec S\right)[/tex]

[tex]\vec T = \frac{7}{4}\cdot \vec Q-\frac{3}{4}\cdot \vec S[/tex]

If we know that [tex]Q(x,y) = (3, 0)[/tex] and [tex]S(x, y) = (-3,-3)[/tex], then we have that [tex]T(x,y)[/tex] is:

[tex]\vec T = \frac{7}{4}\cdot (3, 0) - \frac{3}{4}\cdot (-3, -3)[/tex]

[tex]\vec T = \left(\frac{21}{4}, 0 \right) + \left(\frac{9}{4},\frac{9}{4}\right)[/tex]

[tex]\vec T = \left(\frac{21+9}{4},\frac{0+9}{4} \right)[/tex]

[tex]\vec T = \left(\frac{15}{2}, \frac{9}{4}\right)[/tex]

[tex]\vec T = (7.5, 2.25)[/tex]

Answer:

h = -0.0166t^2 + 30.

Step-by-step explanation:

The graph of the flight is a parabola which opens down and is symmetrical about the y axis, passes through the x axis at -42.5 and 42.5 and has a vertex at (0, 30).

So we have -a(t^2) + 30 = 0   where t is the time

(42.5)^2 * -a  = -30                (42.5 as its 1/2 * 85).

a = 30/2806.25

= 0.01661

So the equation is height h = -0.0166t^2 + 30

Answer:B 100%

Step-by-step explanation:

Answer:

Step-by-step explanation:

Perimeter of a rectangle = 2(L+W)

L is the length of the triangle

W is the width

If the perimeter of a rectangle is represented by the expression [tex]2\left(3x+1\right)+2[/tex]

In order to know what wat each part represents, we will rewrite the given equation in the form 2(L+W).

Given

[tex]2\left(3x+1\right)+2x[/tex]

Perimeter of a rectangle

[tex]2L+2W[/tex]

Compare the given function with the perimeter to get L and W

[tex]L = 3x+1 \ and \ W = x[/tex]

Hence the following statements explain correctly what each part of the expression represents

- One side of the rectangle measures x (the length)

- One side of the rectangle measures 3x + 1 (the width)

- 2 is the coefficient in each term that represents 2 lengths and 2 widths in a rectangle.

Answer:

Son's age=7

Daniel's age=33

Step-by-step explanation:

d = s + 26

d + 6 = 3(s + 6)

Substitute!

s + 26 + 6 = 3s + 18

Simplify and distribute:

s + 32 = 3s + 18

Subtract s:

32 = 2s + 18

Subtract 18:

14 = 2s

Divide by 2:

7 = s

d = 7 + 26

d = 33

Answer:

-37, -36, -35

Step-by-step explanation:

x+x+1+x+2=x-71

3x+3=x-71

2x=-74

x=-37

So x=-37, x+1=-36, x+2=-35

Add these three numbers and you get -108 which is 71 less than -37

Answer:-15 is correct

Step-by-step explanation:

(-6)-9 is the same as -6-9 since parenthesis aren’t really needed in thins case and if you use the order of operations you go left to right. So, -6-9=-15 because a negative- a negative= a negative.
