Answer: 450 kcal
Step-by-step explanation:
So you know the food is 360 kcal per 1 cup
by setting up a proportion, you can relate the number of kcal to cups.
[tex]\frac{360 kcal}{1 cup} = \frac{?kcal}{(3/4 +1/2)cup} \\\\[/tex]
we can simplify the fraction to this:
[tex]\frac{360 kcal}{1 cup} = \frac{?kcal}{(5/4)cup} \\\\[/tex]
by cross multiplying you can solve the proportion
(360) * (5/4) = (?) * (1)
simplifying gets this:
450 = ?
so he ate 450 kcal total
-3x + y = 10
solve the equation for Y
Answer:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-3*x+y-(10)=0
Pull out like factors :
-3x + y - 10 = -1 • (3x - y + 10)
) What is 35% of 10?
0.35(10)
Answer:
3.5
Step-by-step explanation:
35% of 10 is the same thing as 0.35(10)
0.35 x 10 = 3 + (0.05 x 10) = 3 + 0.5 = 3.5

Clayton wants to be a musician. After school one afternoon, he spends half his time practicing his drums and 3/4 of the remaining time on homework and dinner. He spends the remaining 3/4hour talking with and texting his friends. How long did he practice the drums?
Answer:
x - x/2 - (x/2)(3/4) - 3/4 = 0
x = 6
so, he spent 3 hours on the drums.
Jacob went bowling over the weekend. On Saturday, he bowled at Bowlero, where he
rented shoes for $3.25 and paid $3.75 for each game. On Sunday, he bowled at the
Cowtown Bowling Center, where he rented shoes for $2.50 and paid $4.00 per game.
If he spent the same amount each day, how many games did he bowl? (Let the
number of games played = 2.)
Answer:
3 games played every Day
Step-by-step explanation:
So for Cowtown Bowling Center the cost of shoes is $2.50, and $4.00 per game
Then the Bowler is $3.25 for shoes and 3.75 per game
So to get the answer your gonna wanna set up the equation like
Saterday =$3.25+$3.75(x), then for
Sunday = $2.50+$4.00(x)
The X is how many games so if you plug in the same amount of game in both
Example
Saterday=$3.25+$3.75(2)=$10.75
Sunday = $2.50+$4.00(2)=$10.50
So if you do 3 then the totals will come out to be the same
Answer
Saterday=$3.25+$3.75(3)=$14.50
Sunday = $2.50+$4.00(3)=$14.50

Answer:Think of the equation as an equation for a line
y=mx+b
where in this case
C= 5 /9 (F−32)
or
C= 5 /9 F - 5/9 x 32
You can see the slope of the graph is 5 /9
, which means that for an increase of 1 degree Fahrenheit, the increase is
5 /9 of 1 degree Celsius.
C= 5 /9 (F)
C= 5/9(1)
C=5/9
Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of
9/5 degrees Fahrenheit.
C= 5/ 9 (F)
1= 5 /9 (F)
(F)= 9 /5
Since
9/5 = 1.8, statement II is true.
The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of 5/9 degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:
C= 5 /9 (F)
C= 5 /9 x 5/9
C=25/81
(which is≠1)
An increase of 5/9
degree Fahrenheit leads to an increase of
25/81.
, not 1 degree, Celsius, and so Statement III is not true.
The final answer is D.

Explain the significant of the arithmetic
modulo in solving problems then support your answer with examples.
Answer:
A familiar use of modular arithmetic is in the 12-hour clock, in which the day is divided into two 12-hour periods. If the time is 7:00 now, then 8 hours later it will be 3:00. Simple addition would result in 7 + 8 = 15, but clocks "wrap around" every 12 hours.

If someone build a house for 50 years how many months did it take to complete
Answer: 600
Step-by-step explanation: 12 months in one year. 12x50=600 months
Answer:
600 months
Step-by-step explanation:
In 1 year there are 12 months, so we take 50 (the years) and multiply that by 12
50x12=600 and we fact check by 600÷12=50. It takes 600 months to build the house over 50 years.

It is estimated that each guest at a party will eat 9/10
pounds of chocolates. How many guest can be served with 27 pounds of chocolate?
Answer:
30 guests
Step-by-step explanation:
If each guest eats 9/10 lbs of chocolate, then they eat 0.9 lbs of chocolate. We have 27 lbs of chocolate to be eaten.
To solve this, simply:
[tex]\frac{27}{.9} =30[/tex]
where 27 lbs is divided by 0.9lbs per guest to equal 30 quests.

pls can i have brainliest?
I'll give brainliest please help
graphing
both of them please
Step-by-step explanation:
It's easier to graph when both equations are in its slope-intercept form, y = mx + b.
System 1: -3x -15y = 15-2x -10y = 10-2x -10y = 10
-2x + 2x - 10y = 2x + 10
-10y = 2x + 10
-10y/-10 = (2x + 10)/-10
y = -1/5x -1 [slope: -1/5, y-intercept (0, -1)]
-3x -15y = 15
-3x + 3x - 15y = 15
-15y = 3x + 15
-15y/-15 = (3x + 15)/-15
y = -1/5x - 1 [slope: -1/5, y-intercept (0, -1)]
To graph this system, plot the y-intercept, (0, -1) on the graph, then use the slope, m = -1/5 (down 1 unit, run 5 units to the right). Repeat the process until you have enough points to connect and create a line.
Because the given systems of linear equations are equivalent, their lines coincide on top of each other. This means that they have infinitely many points of intersection. Hence, they have infinite solutions.
System 2: 8x + 6y = 244x + 3y = 98x + 6y = 24
6y = -8x + 24
6y/6 = (-8x + 24)/6
y = -4/3x + 4 [slope: -4/3, y-intercept (0, 4)]
4x + 3y = 9
3y = -4x + 9
3y/3 = (-4x + 9)/3
y = -4/3x + 3 [slope: -4/3, y-intercept (0, 3)]
Use the same techniques as described in the first part. Plot the y-intercepts on the graph, then use the slope of each equation to plot other points.
These lines are parallel, which implies that they will never intersect each other. Hence, there's no solution to this system.
Attached are the screenshots of the graphed systems of linear equations.

Find the equation of the line through the points (−2,5) and (4,9).

Answer:
2x -3y = -19
Step-by-step explanation:
Taking the differences between the given points, we have ...
(Δx, Δy) = (4, 9) -(-2, 5) = (6, 4)
The equation of the line can be written ...
Δy·x -Δx·y = Δy·(x1) -Δx·(y1) . . . . . for point (x1, y1) on the line
4x -6y = 4(-2) -6(5) = -38
Dividing by 2 gives the standard form equation ...
2x -3y = -19
_____
Additional comment
The original equation 4x-6y=-38 satisfies the requirements of this problem. However, "standard form" requires the numbers in the equation be mutually prime (in addition to the problem requirements). That is, they must have no common factors. Hence, we must remove the common factor of 2 in order to have true "standard form."

Answer:
C. x+8=3x
Step by step explanation:
First, subtract 8 from both sides of the equation
x+8=3x
x+8-8=3x-8
Then, simplify it by subtracting again
x+8-8=3x-8
x=3x-8
Then, subtract 3x from both sides of the equation
x=3x-8
x-3x=3x-8-3x
Then, simplify by combining the terms
x-3x=3x-8-3x
-2x=3x-8-3x
-2x=3x-8-3x
-2x= -8
Then, divide both sides of the equation by the same term
-2x= -8
-2x/-2 = -8/-2
Then, simplify by cancling terms that are in both the numerator and denominator
-2x/-2 = -8/-2
x= -8/-2
Finally, divide the numbers
x= -8/-2
x=4

Find the slope intercept form of the equation of the line that’s has the given properties (1 , 3) m=1/4
Answer:
y = 1/4x + 11/4
Step-by-step explanation:
Given the slope, m = 1/4, and the point, (1, 3):
We can substitute these values into the slope-intercept form, y = mx + b, in order to solve for the y-intercept.
The y-coordinate (b) of the point, (0, b ) is the y-intercept of the line where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.
y = mx + b
3 = 1/4(1) + b
3 = 1/4 + b
Subtract 1/4 from both sides:
3 - 1/4 = 1/4 - 1/4 + b
11/4 = b
The y-coordinate, b, of the y-intercept is 11/4.
Therefore, the slope-intercept form is: y = 1/4x + 11/4
