Solve for r when
- 5 = – 4

r=
What is r?
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
20yz/28xyz simplify.
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

Step-by-step explanation:
The quotient of 363636 and 333 is jjj.
Step-by-step explanation:
3=j
so 36(j) now divide that 36 divided 3 = 12
so 12=j
(This was kind of confusing but this is the best I can give you!)
Answer:
12
Step-by-step explanation:
Ali can bake 105 cookies in 3 hours. At that rate, how many cookies can she bake in 5 hours?
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

A line passes through points with coordinates
(3,7) and (-2,-3). What is the equation of the
line?
1) y = 2x + 1
2) y = 2x + 4
3) y = -2x +1
4) y = = -2x + 13
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: =16y−25
Step-by-step explanation:
Distribute:
=7+(−4)(3)+(−4)(−4y)+(−4)(5)
=7+−12+16y+−20
Combine Like Terms:
=7+−12+16y+−20

Gina takes three hours of dance classes for x weeks. Which expression shows the number of hours Gina dances?
x - 3
x + 3
3x
x ÷ 3
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).

1. The distance that Giselle can run is a function of the amount of the time she speeds running. Giselle runs 3 miles in 21 minutes. Assume she runs at a constant rate.
a. Write an equation in two variables that represents her distance run, y, as a function of the time, x, she spends running
b. Use the equation you wrote in part (a) to determine how many miles Giselle can run in 14 minutes.
c. Use the equation you wrote in part (a) to determine how many miles Giselle can run in 28 minutes.
d. Use the equation you wrote in part (a) to determine how many miles Giselle can run in 7 minutes
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.
como seria una ecuacion de (2,3) si la pendiente es -2
Answer:
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

0. The weight of an object on the Moon is about 16.5% of its weight on Earth. The weight of an astronaut on the Moon is 24.75 pounds. How much does the astronaut weigh on Earth?
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.
Can someone help me?
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.

write the equation of the line
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.
