Nikki is participating in a charity walk this
weekend. She walks at a pace of 4.2 miles
per hour. How long will it take her to walk
35.7 miles?
Answer:
8.5 hours
Step-by-step explanation:
We know that it takes Nikki 1 hour to walk 4.2 miles.
We need to figure out how long it will take her to walk 35.7 miles.
This is our expression; 35.7 ÷ 4.2.
Let's go ahead and divide these two numbers.
(35.7 ÷ 4.2) = 8.5
So It will take Nikki 8.5 hours to walk 35.7 miles.

Maria is 8 years older than her brother, and the sum of their ages is 72 years. How old is her brother?
Maria is 8 years older than her brother, and the sum of their ages is 72 years. How old is her brother?
Answer:Maria's brother is 32 years old.
Solution and Explanation:Let's assume that:
Maria's brother = x years oldAs per the provided information, Maria is 8 years older than her brother, so her age can be expressed as [tex]\large\rm{x+8}[/tex].
The sum of their ages is 72 years, so we can set up the equation:
[tex]\Large\begin{aligned}\rm{x + (x+8)}& =\rm{72}\end{aligned}[/tex]
Substitute Maria's age into the above equation and solve for x:
[tex]\Large\begin{aligned}\rm{x + (x+8)}& =\rm{72}\\\rm{2x + 8}&=\rm{72}\\\rm{2x + \cancel{8 \red{-8}}}&=\rm{72 \red{-8}}\\\rm{2x}&=\rm{64}\\\rm{\dfrac{\cancel{2}x}{\cancel{\red{2}}}}&=\rm{\dfrac{64}{\red{2}}}\\\rm{x}&=\bold{32}\end{aligned}[/tex]
[tex]\therefore[/tex] Maria's brother is 32 years old.
To check our answer, we can substitute [tex]\large\rm{x = 32}[/tex] into the equation [tex]\large\rm{x + (x+8) = 72}[/tex]:
[tex]\Large\begin{aligned}\rm{x + (x + 8)}&=\rm{72}\\\rm{\red{32} + (\red{32}+8)} &=\rm{72}\\\rm{32 + 40}&=\rm{72}\\\rm{72}&=\rm{72}\end{aligned}[/tex]
This is true, so our assumption that Maria's brother's age is 32 is correct.

Answer:
Maria's brother is 32 years old.
Step-by-step explanation:
Let's denote Maria's brother's age as [tex]\bf{x}[/tex]. Since Maria is 8 years older than her brother, her age can be represented as [tex]\bf{x + 8}[/tex]. The sum of their ages is 72, so we can write the equation:
[tex]\LARGE \boxed {\boxed{x + (x + 8) = 72}}[/tex]
Solving this equation, we get:
[tex]2x + 8 = 72[/tex]Now, we need to isolate [tex]x[/tex]. First, we can subtract 8 from both sides:
[tex]2x = 64[/tex]Next, we can divide both sides by 2:
[tex]x = 32[/tex]So, Maria's brother is 32 years old.

PLEASE HELP ILL MARK BRINLIEST
Answer:
Step-by-step explanation:
4+2S=12+S
in the left side there is one triangle so its value is 4 and two square so its value is 2S because you don't know the value of the square.
In the right side, there is 3 Triangles and one square so its value is 12 (3*4)+S

Name the constant of variation for y equals 1/4x then find the slope of the (0,0) and (4,1)... please
Answer:
Constant of variation: 1/4
Slope of the line: 1/4
Step-by-step explanation:
The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.
The slope formula states that m = (y2 -- y1) / (x2 -- x1). The slope formula can be read as "slope equals the second y coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate".

A recipe calls for five minutes of cooking time for three pounds of
meat. Write an equation that defines this linear model and determine
how long would be needed to cook 37 pounds of meat?
Answer:
62 minutes are required to cook 37 pounds of meat.
Step-by-step explanation:
Let cooking time = y
pounds of meat = x
So, The equation for this linear model will be:
y=(5/3)*x
Now, we need to find how long would be needed to cook 37 pounds of meat?
So x= 37
Putting it in linear model and finding value of x
y=(5/3)*37
y=62 minutes
So, 62 minutes are required to cook 37 pounds of meat.
