Answer 1

Answer:

x = 18

Step-by-step explanation:

Given:

a = 2x +3b = 4x - 7

Finding x for which 3b = 5a:

3b = 5a3(4x - 7) = 5(2x + 3)12x - 21 = 10x + 1512x - 10x = 15 + 212x = 36x = 36/2x = 18
Answer 2

Answer:

x = 18

Step-by-step explanation:

Plug in 4x-7 for b and 2x+3 for a in 3b = 5a

3(4x-7) = 5(2x +3)

Solve for x:

12x-21 = 10x+15

2x = 36

x=18

Answers

Answer:

[tex] \boxed{ \bold{ \boxed{ \sf{15 \: cookies}}}}[/tex]

Step-by-step explanation:

Total cookies = 150

percentage of cookies that she ate = 10 %

To find : Number of cookies that she ate

[tex] \sf{10\% \: of \: 150}[/tex]

To convert percent into fraction, divide it by 100 and remove the % symbol.

⇒[tex] \sf{ \frac{10}{100} \times 150}[/tex]

⇒[tex] \sf{15 \: cookies}[/tex]

Thus, She ate 15 cookies.

Answers

Answer: B) y = -x

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

Work Shown:

g(x) = x^2-2

g(-2) = (-2)^2-2

g(-2) = 2

Saying (-2, g(-2)) is the same as saying (-2, 2)

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

g(x) = x^2-2

g(1) = 1^2 - 2

g(1) = -1

Saying (1, g(1)) is the same as saying (1, -1)

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

Let's find the slope of the line through (-2,2) and (1,-1)

m = (y2 - y1)/(x2 - x1)

m = (-1-2)/(1-(-2))

m = (-1-2)/(1+2)

m = -3/3

m = -1

Now turn to point slope form to find the equation

y - y1 = m(x - x1)

y - 2 = -1(x - (-2))

y - 2 = -(x + 2)

y - 2 = -x - 2

y-2+2 = -x-2+2 ... add 2 to both sides

y = -x

You could use the other point (1,-1) and you'd get the same answer. The slope m = -1 is the same each time.

Elizabeth wrote 3.3 - 0.21= 1.2 Is her answer​ reasonable? Explain why or why not. Choose the correct answer below and fill in the answer box to complete your choice. A. The estimate would be 0-0= nothing​, so her answer is reasonable. B. The estimate would be 4-0= nothing​, so her answer is not reasonable. C. The estimate would be 3-0= nothing​, so her answer is not reasonable. D. The estimate would be 3-0= nothing​, so her answer is reasonable.

Answers

Answer:

The estimate would be 3-0= nothing​, so her answer is not reasonable.

Step-by-step explanation:

Given the expression written by Elizabeth as  3.3 - 0.21= 1.2, to check if Elizabeth expression is reasonable or not, we need to check if her answer is close to or equal to the answer of the diiferebce between 3.3 - 0.21.

Converting 3.3 and 0.21 to fraction

3.3 = 33/10

0.21 = 21/100

Taking the difference of both fractions

[tex]= \dfrac{33}{10} -\dfrac{21}{100} \\\\= \dfrac{330-21}{100} \\\\= \dfrac{309}{100} \\\\= 3.09\\[/tex]

Hence 3.3 - 0.21 = 3.09 ≈ 3.0 (to nearest whole number). Comparing Elizabeth answer which is 1.2 to the answer f=gotten, it can be seen that her answer is far from the right answer with a difference of about 1.8 (3.0-1.2). This large difference makes Elizabeth answer unreasonable.

D.

The estimate would be 30

3​, so her answer is not reasonable

Answers

Answer:

  A. 0

  B. -66

  C. 4

  D. 998

  E. -12

Step-by-step explanation:

A. By definition, the sum of anything and its additive inverse is zero.

__

B. If you have trouble with sums, your calculator can help.

  -22 + (-44) = -22 -44 = -66

__

C. -36/x = -9 can be solved by multiplying by x and dividing by -9:

  -36 = -9x

  -36/-9 = x = 4

Since the product of the divisor and quotient is the dividend, dividing the dividend by either gives the other. Here, your dividend is -36 and your quotient is -9. To find the divisor, you can divide -36 by -9, as we did.

__

D. The absolute value function changes the sign of negative numbers to positive:

  |-998| = 998

What is the solution to this system of equations?
x + 3y - z = 6
4x - 2y + 2z= -10
6x + z= -12

(an explanation would be great because i barely understand how to do this)

Answers

Answer:

[tex]x=-3, y=5, z=6[/tex]

Step-by-step explanation:

1. Divide by 2 both sides in the second equation:

[tex]4x - 2y + 2z= -10[/tex] [tex]2x - y + z= -5[/tex]

2. From the third equation find z in terms of x:

[tex]6x + z= -12[/tex] [tex]z= -6x-12[/tex]

3. Add up the first and new second equations and find y in terms of x:

[tex](x+2x)+(3y-y)+(-z+z)=6+(-5)[/tex] [tex]3x+2y=1[/tex] [tex]2y=1-3x[/tex] [tex]y=0.5-1.5x[/tex]

4. Put new alternatives instead of y and z in the first equation:

[tex]x+3(0.5-1.5x)-(-6x-12)=6[/tex] [tex]x+1.5-4.5x+6x+12=6[/tex] [tex]2.5x=-7.5[/tex] [tex]x=-3[/tex]

5. Now we can easily find other two unknowns by using their equations by means of x:

[tex]y=0.5-1.5\times(-3)[/tex] [tex]y=0.5+4.5[/tex] [tex]y=5[/tex][tex]z=-6\times(-3)-12[/tex] [tex]z=18-12[/tex] [tex]z=6[/tex]

Answer:

Step-by-step explanation:

2x + 6y - 2z = 12

12x - 6y + 6z = -30

14x + 4z = -18

6x + z = -12

14x + 4z = -18

-24x - 4z = 48

-10x = 30

x = -3

6(-3) + z = -12

-18 + z = -12

z = 6

-3 + 3y - 6 = 6

-9 + 3y = 6

3y = 15

y = 5

x = -3, y = 5, z = 6

A line passes through the points (2,3) and (6,y) with a slope of 2. What is the value of y?

Answers

Answer:

5

Step-by-step explanation:

The slope of a line is always rise over run.

We need to make the rise over run equivalent to 2 to find the value of y.

Looking at the x-coordinates, 2 and 6, we can see there is an increase in 4.

Now we ask: What number, times 2, will equal 4?

That is 2.

So we have to make the increase in the y coordinates 2.

If we have the original point 3, an increase in 2 is 5.

So y is 5.

Hope this helped!

Answer:

11 = y

Step-by-step explanation:

Using the slope formula

m = (y2-y1)/(x2-x1)

2 = (y-3)/(6-2)

2 = (y-3)/4

Multiply each side by 4

2*4 = y-3

8 = y-3

Add 3  to each side

8+3 = y-3+3

11 = y

What is the sum of the first 150 odd positive integers?
Show work please!!!

Answers

Answer:

11325.

Step-by-step explanation:

Step 1: address the formula, input parameters & values.

Input parameters & values:

The number series 1, 2, 3, 4, . . . . , 149, 150.

The first term a = 1

The common difference d = 1

Total number of terms n = 150

Step 2: apply the input parameter values in the formula

Sum = n/2 x (a + Tn)

= 150/2 x (1 + 150)

= 22650/2

1 + 2 + 3 + 4 + . . . . + 149 + 150 = 11325

Therefore, 11325 is the sum of positive integers up to 150.

The sum of the first 150 odd positive integers is 11325.

The number series 1, 2, 3, 4, . . . . , 149, 150.

The first term a = 1

The common difference d = 1

Total number of terms n = 150

Sum = n/2 x (a + Tn)

= 150/2 x (1 + 150)

= 22650/2

1 + 2 + 3 + 4 + . . . . + 149 + 150 = 11325

5m -10 -10 = 6 + 2-2m         Now combine like terms on both sides

5m -20 = 8- 2m     Now add 2m to both sides

5-9(8 - 2x) < 2x - 115 solve for x​

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write out equation

5 - 9(8 - 2x) < 2x - 115

Step 2: Distribute parenthesis

5 - 72 + 18x < 2x - 115

Step 3: Combine like terms

-67 + 18x < 2x - 115

Step 4: Add 67 on both sides

18x < 2x - 48

Step 5: Subtract 2x on both sides

16x < -48

Step 6: Divide both sides by 16

x < -3

And we have our answer!

Answer:

x<-3

Step-by-step explanation:

5−9(8−2x)<2x−115

Use the distributive property to multiply −9 by 8−2x.

5−72+18x<2x−115

Subtract 72 from 5 to get −67.

−67+18x<2x−115

Subtract 2x from both sides.

−67+18x−2x<−115

Combine 18x and −2x to get 16x.

−67+16x<−115

Add 67 to both sides.

16x<−115+67

Add −115 and 67 to get −48.

16x<−48

Divide both sides by 16. Since 16 is >0, the inequality direction remains the same.

x<-48/16

Divide −48 by 16
