Can someone answer this please

Answer:

a = -3

Step-by-step explanation:

a − 2 + 3 = −2

Combine like terms

a+1 = -2

Subtract 1 from each side

a+1-1 = -2-1

a = -3

Answer:

a-2+3=-2

a+1=-2

a=-2-1

a=-3

Answer:

Answer:

7.05 simplified rational

Answer:

irrational number

Step-by-step explanation:

Answer:

[See Below]

Step-by-step explanation:

✦ First split the equation in little pieces and solve them:

  ✧ 4 - 16 = -12

  ✧ 4 + 4² = 20 (4² = 16)

✦ Now divide them:

  ✧ -12 ÷ 20 = -0.6

So I'm guessing you're trying to simplify 4²... so it'd be 16 because none of the choices are the simplified version of the problem.

Answer:{d,t}={187, 17/2}

Step by step explanation :

System of Linear Equations entered :

[1] d - 18t = 34

[2] d - 22t = 0

Graphic Representation of the Equations :

-18t + d = 34 -22t + d

Solve by Substitution :

// Solve equation [2] for the variable d

[2] d = 22t

// Plug this in for variable d in equation [1]

[1] (22t) - 18t = 34

[1] 4t = 34

// Solve equation [1] for the variable t

[1] 4t = 34

[1] t = 17/2

// By now we know this much :

d = 22t

t = 17/2

// Use the t value to solve for d

d = 22(17/2) = 187

Answer:

[tex]d=52\\t=\frac{26}{11}[/tex]

Step-by-step explanation:

1 solve for d in d =18+34

solve for d

[tex]d=18+34[/tex]

Simplify 18+34  to  52

[tex]d=52[/tex]

2 substitute d=52 into d=22t

Start with the original equation

[tex]d=22t[/tex]

Let d=52

[tex]52=22t[/tex]

3 Solve for t in 52=22t

Solve for t

[tex]52=22t[/tex]

Divide both sides by 22

[tex]\frac{52}{22} =t[/tex]

Simplify  [tex]\frac{52}{22}[/tex][tex]to \frac{26}{11}[/tex]

[tex]\frac{26}{11} =t[/tex]

Switch sides

[tex]t=\frac{26}{11}[/tex]

​4 Therefore

[tex]d=52\\t=\frac{26}{11}[/tex]

Answer:10

Step-by-step explanation:

Answer and Step-by-step explanation:

Sol: the ratio formula is

x-x1/x2-x = ratio     and    y-y1/ y2-y= ratio

x-(-7)/0-x=2/1          and    y-17/0-y=2/1

x+7=2(-x)                   and   y-17 = -2y

x+2x=-7                    and y+2y =17

3x=-7                       and 3y = 17

x=-7/3                   and y= 17/3

coordinates of point p that partition the segment in ratio is (-7/3, 17/3)

The midpoint formula is:

M= (x1+x2/2,        y1+y2/2)

  = (-7+0/2,          17+0/2)

   = (-7/2,           17/2) are the midpoint of AB.

Answer:

m = -1

Step-by-step explanation:

Solve for m:

5 (m - 7) = -8 (3 m + 8)

Hint: | Write the linear polynomial on the left hand side in standard form.

Expand out terms of the left hand side:

5 m - 35 = -8 (3 m + 8)

Hint: | Write the linear polynomial on the left hand side in standard form.

Expand out terms of the right hand side:

5 m - 35 = -24 m - 64

Hint: | Move terms with m to the left hand side.

Add 24 m to both sides:

24 m + 5 m - 35 = (24 m - 24 m) - 64

Hint: | Look for the difference of two identical terms.

24 m - 24 m = 0:

24 m + 5 m - 35 = -64

Hint: | Group like terms in 24 m + 5 m - 35.

Grouping like terms, 24 m + 5 m - 35 = (5 m + 24 m) - 35:

(5 m + 24 m) - 35 = -64

Hint: | Add like terms in 5 m + 24 m.

5 m + 24 m = 29 m:

29 m - 35 = -64

Hint: | Isolate terms with m to the left hand side.

Add 35 to both sides:

29 m + (35 - 35) = 35 - 64

Hint: | Look for the difference of two identical terms.

35 - 35 = 0:

29 m = 35 - 64

Hint: | Evaluate 35 - 64.

35 - 64 = -29:

29 m = -29

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 29 m = -29 by 29:

(29 m)/29 = (-29)/29

Hint: | Any nonzero number divided by itself is one.

29/29 = 1:

m = (-29)/29

Hint: | Reduce (-29)/29 to lowest terms. Start by finding the GCD of -29 and 29.

The gcd of -29 and 29 is 29, so (-29)/29 = (29 (-1))/(29×1) = 29/29×-1 = -1:

Answer:

2 * 10 + 6 * .1 + 5 * .01

Step-by-step explanation:

Answer:

[tex]m=4[/tex]

Step-by-step explanation:

So we have the equation:

[tex]4x-20=mx-5m[/tex]

First, factor out a m from the right:

[tex]4x-20=m(x-5)[/tex]

Divide both sides by x-5:

[tex]m=\frac{4x-20}{x-5}[/tex]

Factor out a 4 in the numerator:

[tex]m=\frac{4(x-5)}{x-5}[/tex]

The (x-5)s cancel. Thus:

[tex]m=4[/tex]

The value of m is 4 :)

Answer:

A . The numbers are 6 and 7, with the smaller number as 6

B. The number is 135

Step-by-step explanation:

A. Let the numbers be a and b

adding both gives 13

a + b = 13 •••••(i)

difference between the two is 1

b - a = 1 ••••••(ii)

So we have two equations that we can solve simultaneously;

b = 1 + a; Substitute this into 1

a + 1 + a = 13

2a + 1 = 13

2a = 13-1

2a = 12

a = 12/2

a = 6

b = a + 1 = 6 + 1 = 7

The numbers are 6 and 7 while 6 is the smaller number

B.Let the number be x

Divide by 5; x/5, then subtract 2 , we get 25

x/5 - 2 = 25

x/5 = 25 + 2

x/5 = 27

x = 5 * 27

x = 135

Answer:

Tim's bean sprout grow by more than [tex]\frac{5}{8} \text{ inches}[/tex].

Step-by-step explanation:

We are given that Tim's bean sprout grew 3 3/8 inches. Teegan's bean sprout grew 2 3/4 inches.

We have to find how many more inches did Tim's bean sprout grow than Teegan's.

Firstly, converting both the mixed fractions in improper fraction get;

Tim's bean sprout grew = [tex]3\frac{3}{8}[/tex] = [tex]\frac{27}{8} \text{ inches}[/tex]

Teegan's bean sprout grew = [tex]2\frac{3}{4}[/tex] = [tex]\frac{11}{4} \text{ inches}[/tex]

Since the denominator of both the fractions is not the same, so we can't compare them both as which is larger or smaller.

Tim's bean sprout grew = [tex]\frac{27\times 1}{8\times 1} = \frac{27}{8} \text{ inches}[/tex]

Teegan's bean sprout grew = [tex]\frac{11 \times 2}{4\times 2}=\frac{22}{8} \text{ inches}[/tex]

Now, we can clearly see that Tim's bean sprout grew more than Teegan's bean sprout.

So, Tim's bean sprout grow by more than = [tex]\frac{27}{8}- \frac{22}{8}[/tex] = [tex]\frac{5}{8} \text{ inches}[/tex]

Hence, Tim's bean sprout grow by more than [tex]\frac{5}{8} \text{ inches}[/tex].

Hi

3*5000 +X*2500 = 25 000

15 000 + 2 500X = 25 000

                2 500X = 25 000 - 15 000

                       2 500 X = 10 000

                               x = 10 000 / 2 500

                                 X = 100/25

                                   X = 4

You need 4 post for  B

3*5000 + 4* 2 500 =  15 000 + 10 000 = 25 000
