−2, −1, 0, 1 Which pair of numbers has a sum of zero? A . 1, −1 B. −2, 0 C.−2, 1 D.−1, 0

Answer:

13

Step-by-step explanation:

3 x 2 + 7

6 + 7  (Do multiplication first)

13 (Then add from left to right)

A one solution because it's x=1

this is the original problem

8x-3=3x+2

we want to have x by itself so. . .

we add three on both sides. it cancels -3. And 2+3=5

8x=3x+5

we subtract 3x on both sides so 8x-3x=5x and 3x cancels on the other side

5x=5

we divide by 5 on both sides to get x by itself

x=1

if it was 1=1 or x=x (the same on both side) it would've been infinite solutions. if the numbers didn't match like 4=6 it would've been no solution

Answer:

[tex]a=3[/tex]

Step-by-step explanation:

So we have the equation:

[tex]4x-2(x+a)=8[/tex]

And we want to find a such that x = 7 is a possible solution.

To do so, substitute 7 for x. Thus:

[tex]4(7)-2(7+a)=8[/tex]

Multiply the left and distribute the right:

[tex]28-14-2a=8[/tex]

Subtract:

[tex]14-2a=8[/tex]

Subtract 14 from both sides:

[tex]-2a=-6[/tex]

Divide by -2: "

[tex]a=3[/tex]

So, the value of a is 3.

And our equation would be:

[tex]4x-2(x+3)=8[/tex]

And we're done!

It's an integer.

An integer is a whole number

Example of integers: -3, -2, -111, 1, 5, 7, 48

Example of  non integers: 0.2, -5.3, anything that isn't a whole number

An irrational number  is a number that follows the rules below

A real number that cannot be expressed as a ratio between two integers.

Any real number that cannot be expressed as a ratio of two integers.

Answer:  4 3/8 ≈ 4.38

Step-by-step explanation:

To start off, note that 4 3/8 is a mixed number, also known as a mixed fraction. It has a whole number and a fractional number. We have labeled the parts of the mixed number below so it is easier to follow along.

4 = Whole number

3 = Numerator

8 = Denominator

To get 4 3/8 in decimal form, we basically convert the mixed number to a fraction and then we divide the numerator of the fraction by the denominator of the fraction.Step 1: Multiply the whole number by the denominator:

4 × 8 = 32

Step 2: Add the product you got in Step 1 to the numerator:

32 + 3 = 35

Step 3: Divide the sum from Step 2 by the denominator:

35 ÷ 8 = 4.375

That's it folks! The answer to 4 3/8 in decimal form is displayed below:

4 3/8 ≈ 4.38

Answer: 8

Step-by-step explanation: Usually you should use prime factorization or the “ladder” method; however, with questions like this that have small, easy numbers, you can simply think about it. Every number’s largest factor is itself, which means that 8 is at least a factor of 8. We also know that 8 times 2 equals 16, hence, the greatest common factor is 8.

Answer:

you look at the slope and y intercept for example,

y=4x+10

the slope is 4 (increases 4/1 at a time)

and the intercept is 10 (the line hits the y axis at 10)

Step-by-step explanation:

6 can go into both of them

Answer:

8/5 is the answer

Step-by-step explanation:

7/10+9/10

7+9/10( because if the lcm is same in both the expression we can write one of them and do according to the sign)

16/10( adding the number)

8/5( dividing the numbers and finding the value in fraction form)

OR,

16/10

1.6( dividing and finding the value in decimal form)

Step-by-step explanation:

An x-intercept of a function occurs when f(x) = 0.

In f(x) = (x-8)(x+9), f(x) will be 0 if either (x-8) is 0 or (x+9) is 0.

Hence, f(x) = 0 when x = 8 or x = -9.

Answer:

x = - 5

Step-by-step explanation:

Given

[tex]\frac{2x-20}{3}[/tex] = 2x ( multiply both sides by 3 to clear the fraction )

2x - 20 = 6x ( subtract 2x from both sides )

- 20 = 4x ( divide both sides by 4 )

- 5 = x , that is x = - 5

Distance = rate x time

Distance = 60 x 3

Distance = 180 miles.

Answer:

180m

Step-by-step explanation:

d= distance traveled => ?m

r= rate => 60m/h

t= time => 3h

Formula=> d=r.t

>d= 60 x 3=> d= 180m

So

d= distance traveled => 180m

r= rate => 60m/h

t= time => 3h

Answer:

The question is incomplete, below is a possible match for the complete question:

Mikel gave a \$1.32$1.32dollar sign, 1, point, 32 tip for an order that cost \$8.80$8.80dollar sign, 8, point, 80. Determine whether or not each tip below is proportional to Mikel's tip. Proportional to Mikel's tip Not proportional to Mikel's tip

1.) \$2.22$2.22dollar sign, 2, point, 22 tip for a \$14.80$14.80dollar sign, 14, point, 80 order

2.) \$1.86$1.86dollar sign, 1, point, 86 tip for a \$10.50$10.50dollar sign, 10, point, 50 order

3.) \$0.78$0.78dollar sign, 0, point, 78 tip for a \$5.20$5.20dollar sign, 5, point, 20 order

Answers

1) proportional to Mike's tip

2) Not proportional to Mike's tip

3) proportional to Mike's tip

Step-by-step explanation:

when two things have the same relative sides, they are said to be proportional.

To determine if the other tips are proportional to Mikel's tip, we will, first of all, determine the size of Mikel's tip, then compare the other tips with it.

Mikel's tip:

$1.32 for $8.80

= [tex]\frac{1.32}{8.80}= 0.15[/tex]

Now, let us compare this with the other tips

1.) $2.22 for 14.80

= [tex]\frac{2.22}{14.80} = 0.15[/tex]

proportional to Mike's tip

2.) $1.86 for $10.50

[tex]\frac{1.86}{10.50} = 0.177\\0.177 \neq 0.15[/tex]

Not proportional to Mike's tip

3.) $0.78 for $5.20

= [tex]\frac{0.78}{5.20} = 0.15[/tex]

proportional to Mike's tip
