PLEASE HELP "A phone sells for $137.99. It is now on sale for 1/10 off the original price. Tom has a coupon for an extra 5% off the sale price. To the nearest dollar, how much less that the original price will Tom pay for the phone."

Answer: m=−3

Step-by-step explanation: −40−2(3m+1/2)=7m−2

−40+(−2)(3m)+(−2)(1/2)=7m+−2

−40+−6m+−1=7m+−2

(−6m)+(−40+−1)=7m−2

−6m+−41=7m−2

−6m−41−7m=7m−2−7m

−13m−41+41=−2+41

−13m/−13=39/−13

m=−3

What mistake I guess Keith did make is he subtracted 2 from -39 which equaled to -37 which caused him divide -37 by 13 when it should have been 39 divided by 13 because he should have left 39 alone and not have subtracted 2 from it also it should not have been negative basically what I'm trying to say is that he did his division and subtraction wrong.

Answer:

5/7X

Step-by-step explanation:

cancel Y and Z from both sides

get the HCF (highest common factor) between 20 and 28 which is 4

then divide both sides with 4

the final answer will be:

5/7X

Answer:

322 is the bigger number

Step-by-step explanation:

Answer: 322

Step-by-step explanation:

d = difference

l = larger number

237 + d = l

237 + (85) = l

l = 322

Answer:

y = 2x + 1

Step-by-step explanation:

[tex]m = \frac{-3 - 7}{-2 - 3}\\ = \frac{-10}{-5}= 2\\y = mx + b \\y = 2x + b\\7 = 2(3) + b\ -> 7 = 6 + b \\b = 1 \\y = 2x + 1[/tex]

Answer:

3x

Step-by-step explanation:

x = number of weeks.

When you plug in the number of weeks for x you'll get the amount of hours she had for dance classes.

Example: She has been doing classes for 3 weeks, how many hours did she do?

3x

3(3)

= 9(She had 9 hours of dance class combined for the past three weeks).

Step-by-step explanation:

There are 240 boxes with 25 bags each. If each bag weighs 0.69 kg. What is the weight of coffee?

Answer:

How does she run so fast anyways

Step-by-step explanation:

A. well y=3 mi and x=21min so then we multiply and figure out that it is  aproximatly 12mi/hr.

B. I beleive is aproximatly 1.5 mi

C.  I think is aproximatly 3.2

Now I know that that is just close but not quite exact but it might get you closer.

Answer:

x+7

Answer:

y=1x+0

Step-by-step explanation:

it is going up by 1 and it cross the y-axis at 0

Answer:

r is 19

Step-by-step explanation:

-4 - 20 = -24

-24 - r = -5

r = 19

Answer:

r=1/20

Step-by-step explanation:

-5=-4-20r    (+4 both sides)

-1=-20r       (times -1 both sides)

1=20r       (divide by 20)

1/20=r

Answer:

y = (3/-2)x + 4.

Step-by-step explanation:

slope intercept form is y = mx + b

1. Lets first look for the y intercept (b). On the graph the line intercepts the y axis at 4. 4 is our b.

2. To find the slope (m) remember rise over run. Counting from lower dot, it goes up 3 and left 2. 3/-2. The two is negative because it is decreasing (towards the left of the graph).

3. Now plug the numbers into slope intercept form. y = (3/-2)x + 4.

Answer: 150 pounds

Step-by-step explanation:

Let the the astronaut weight on Earth be represented by x.

Based on the information given in the question, thus can be formed into an equation as:

16.5% of x = 24.75

16.5% × x = 24.75

16.5/100 × x = 24.75

0.165x = 24.75

x = 24.75/0.165

x = 150 pounds

The astronaut weigh 150 pounds on Earth.

Step-by-step explanation:

3=j

so 36(j) now divide that 36 divided 3 = 12

so 12=j

Hola, antes de dar la respuesta quisiera recomendarte una app llamada m a t h w a y (sin espacios) esto te va a ayudar con preguntas sobre matematica y super rapido.

Step-by-step explanation:

(2,3) pendiente de -2

                                           1. Usa la fórmula de la ecuación de la recta para

                                              hallar b

y = mx + b

                                          2.  Substituye el valor de m, x y "y" en la ecuacion

3 = (-2) · (2) +b                      

                                           3. Calcula para hallar el valor de b

b = 7

                                          4. Ahora con el valor de b, calcule de nuevo

y = mx + b

3 = -2x +7

Espero esto haya ayudado en algo, sino puedes intentar buscando en el sitio que recomende.      

so first you find out how many she can bake in 1 hour so you divide 105 and 3 which is 35

so since she bakes 35 cookies and hour you multiply 35 by how many hours she cooks

so 35 x 3 =105                    35 x 5=175

Ali cooks 175 cookies in 5 hours
