What’s Jake’s error

Step-by-step explanation:

"Write an expression to show k less than 10"

"less than" means that the number is being subtracted from a different number.

This means that "10" is being subtracted from "k"

Thus,

k - 10 is the appropriate expression for the statement, "k less than 10"

ANSWER:   k - 10

Answer:

adjust city gallons to 3 gallons and freeway to 7 gallons

make your line in the chart:

3   |  10-3 = 7   |   3(25) = 75   |   7(40) = 280   |   75 =280 =355   |   355   |   yes

Step-by-step explanation:

x = city gallons

y = freeway gallons

x+y = 10        then y = 10-x

25x+40y = 355

substitute for y

25x+40(10-x) = 355

25x+400-40x = 355

-15x+400 = 355

subtract 400 from each side

-15x = -45

divide both sides by -15

-15x/-15 = -45/-15

x = 3 gallons

y = 7 gallons

Answer and Step-by-step explanation:

Let's solve your equation step-by-step.

−2(x+5)=4

Step 1: Simplify both sides of the equation.

−2(x+5)=4

(−2)(x)+(−2)(5)=4(Distribute)

−2x+−10=4

−2x−10=4

Step 2: Add 10 to both sides.

−2x−10+10=4+10

−2x=14

Step 3: Divide both sides by -2.

-2x/2 = 14/-2

x equals...

x=-7

Answer:

Look just at finding the linear model. Two points. Use price per gallon for x and gallons per hour sold for y. Your two points (x,y) are (2.15,1600) and (2.55,800).

Slope m=%281600-800%29%2F%280.15-0.55%29

m=800%2F0.40

m=2000

Using point-slope form for a line, and the lower-y point,

y-800=2000%28x-2.55%29

highlight%28y=2000%28x-2.55%29%2B800%29

Answer:

I got 104

Step-by-step explanation:

From our given information, since Angle DGF from a 90 degree angle, Due to our linear pair rule EGF is also a perpendicular angle. EGF and DGC are vertical angles so Angle DGC is 90 degrees.

Triangle DGC have two interior angles 90 and 37 so using the triangle interior theorem we can find the 3r

d side

[tex]90 + 37 + x = 180[/tex]

[tex]127 + x = 180[/tex]

[tex]x = 53[/tex]

Know that angle is 53 we can add 53 and 51 together to find Angle D full degree measure is 104.

Adjacent angles in parallelogram are supplementary so angle d plus angle c equals 180.

Angle C measure has to add up to 76 then so

[tex]37 + x = 76[/tex]

[tex]x = 39[/tex]

So the missing angle is 39 and angle c full side measure is 76.

Angle B and Angle C

are also adjacent angles so

[tex]76 + x = 180[/tex]

x=104

B=104

Answer:

BD=13

(This must not be drawn to scale)

Step-by-step explanation:

You have to use the Angle Bisector Theorem to get a ratio.

12/x=27/(x+5)

cross multiply

12(x+5)=27x

12x+60=27x

60=27x-12x

60=15x

60÷15=x

x=4

BD=x+x+5=4+4+5=13

Answer:

70 kilometers

Step-by-step explanation:

Set up a proportion where x is the actual distance

[tex]\frac{1}{20}[/tex] = [tex]\frac{3.5}{x}[/tex]

Cross multiply:

x = (20)(3.5)

x = 70

So, the actual distance is 70 km

Answer:

7.6,7.45,7.48,7.431,7.504,7.536

this us your answer

Answer:

Least to greatest order:

7.431 < 7.45 < 7.48 < 7.504 < 7.536 < 7.6

Greatest to least order:

7.6 > 7.536 > 7.504 > 7.48 > 7.45 > 7.431

Answer:

B

Step-by-step explanation:

Assuming Part A is the situation where the bags aren't merged, the probability of drawing a "1" followed by a "B" is (1/3)(1/4) or 1/12. This is because you have a 1/3 chance of getting a "1" and a 1/4 chance of getting a "B".

Now if we merge the bags, we have a 1/7 chance of getting a "1". We then have a 1/6 chance of getting a "B". This is because after we complete the first draw, the bag only has 6 remaining not 7. This gives us a probability of (1/7)(1/6) or 1/42.

So we know the probability will change so C is wrong. In both scenarios, we draw two balls anyways so A is wrong.

This leaves B, which is supported by the reasoning presented above.

Answer:

$150

Step-by-step explanation:

90/60=1.5 tthat means 1% of the bike costs $1.50. You ar trying to find 100% so multiply by 100. 1.5x100=150

Answer:

$150

Step-by-step explanation:

You can divide the 90 by 0.60 to get 150. You can check again by multiplying 150 by 0.6 to get 90, which Victor has 60% of the total (being 150)

Hope this helps!

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

In 1985, there were 20 students

In 2005, there were 45 students

This is a change of 45-20 = 25 students.

This amount of change is divided by the original amount 20 to get 25/20 = 1.25 and converts to 125% when you move the decimal point 2 spots to the right.

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

If you want, you can use the formula below

x = old value = 20

y = new value = 45

z = percent change

z = [ (y-x)/x ] * 100%

z = [ (45-20)/20 ] * 100%

z = (25/20) * 100%

z = 1.25*100%

z = 125%

The z value being positive means we have a percent increase.

It's possible to have over 100% increase since 100% of 20 is 20. Having a 100% increase means we increased by 20. Since we increased by more than 20, this means the increase must be over 100%.

the missing side of the right triangle is 10.568

a² + b² = c²

Which c is the hypotenuse part of triangle.

a = 5.2

b = 9.2

c = ...?

so the missing part is c.

a² + b² = c²

5.2² + 9.2² = c²

111.8 = c²

c = √111.8

c = 10.568

Answer:

-3

Step-by-step explanation:

7(-3x-7y-56)

-21x-49y-392

-3(-7x+10y-1)

21x-30y+3

because the eq. multiplied by 7 is negative, the second eq mus be positive in order to eliminate the x variable. this is why we multiply by a (-). by multiplying the second eq by 3, both eq. will result in a coefficient of 21. one positive one negative allowing the x variable to be eliminated from the problem.

Answer:

[tex]x=12[/tex]

Step-by-step explanation:

Notice that the segment bisects the obtuse angle.

Then by the Angle Bisector Theorem:

[tex]\displaystyle \frac{x-4}{6}=\frac{x}{9}[/tex]

Cross-multiply:

[tex]6(x)=9(x-4)[/tex]

Distribute:

[tex]6x=9x-36[/tex]

So:

[tex]-3x=-36[/tex]

Therefore:

[tex]x=12[/tex]

Answer:

THE NUMBERS ARE 10 AND 5

Step-by-step explanation:

LET THE ANOTHER NUMBER BE X THEN

ONE NUMBER = X - 5

BY THE QUESTION

X - 5 + X = 15

2X = 15 + 5

2X = 20

X = 10

X - 5 = 10 - 5 = 5

Answer:

hi 5 and 10 is required no.

let no. be x

another no.be x+5

Step-by-step explanation:

sum=15

x+x+5=15

2x=15-5

2x=10

x=10/2=5

x+5=5+5=10

Answer:

2/5

Step-by-step explanation:

we know any number raised to power 1/2 means that we need to find the square root of that number.

(4/25)^1/2= =√(4/25)√4/√25

√4=2

√25=5

√(4/25=2/5

Answer:

[tex]H = 3x^2y[/tex]

Step-by-step explanation:

Given

[tex]V = 36x&^6y^8[/tex]

[tex]L = 4x^3y^5[/tex]

[tex]W = 3xy^2[/tex]

Required

Find the height of the prism

Volume (V) is calculated as:

[tex]V =LWH[/tex]

Substitute values for V, L and W

[tex]36x^6y^8 =4x^3y^5 * 3xy^2 * H[/tex]

Make H the subject

[tex]H = \frac{36x^6y^8}{4x^3y^5 * 3xy^2}[/tex]

[tex]H = \frac{36x^6y^8}{4*3x^3*x*y^5y^2}[/tex]

[tex]H = \frac{36x^6y^8}{12x^4*y^7}[/tex]

Divide:

[tex]H = 3x^{6-4}y^{8-7}[/tex]

[tex]H = 3x^2y[/tex]

The height of the prism is: [tex]3x^2y[/tex]

Answer:

d = 0.4

Step-by-step explanation:

-10 (d + 1) = - 14

=> -10d - 10 = -14

=> -10d = -14 + 10

=> -10d = -4

=> 10d = 4

=> d = 4 / 10

=> d = 0.4

Answer:

x=-11, -1, and 3

Step-by-step explanation:

x^3+9x^2-25x-33=0

There are formulas to solve cubics, but that probably is not the way you are expected to go.  Here is a trial and error approach that works in this case.

Assume that the cubic can be factored and that the roots are r1, r2, and r3.  Then the factored form is

(x-r1)(x-r2)(x-r3)=0

This shows that the constant must equal the product of the roots.

(r1)(r2)(r3)=-33

One possibility is that the roots are integers.  In this case, a factor of 33 might work.  Prime factorization of 33 gives 3 and 11.  Try 3.  Then (x-3) is a factor.

Divide the cubic by (x-3).  It works. the result is

x^2+12x+11

This has factors of (x+11) and (x+1).  Therefore, the roots are 3, -1, and -11
