Given:
Number of times Jenna feeds her cat = 2
Cat food each time [tex]=\dfrac{3}{4}\text{ can}[/tex]
Number of days = 5
Number of cans she bought = 8
To find:
Did Jenna buy enough cat food.
Solution:
Required food for each time [tex]=\dfrac{3}{4}\text{ can}[/tex]
Jenna feeds her cat twice a day.
Required food for a day [tex]=2\times \dfrac{3}{4}\text{ can}[/tex]
[tex]=\dfrac{3}{2}\text{ can}[/tex]
Required food for 5 days [tex]=5\times \dfrac{3}{2}\text{ can}[/tex]
[tex]=\dfrac{15}{2}\text{ can}[/tex]
[tex]=7.5\text{ can}[/tex]
Since, 7.5 cans < 8 cans, therefore, Jenna buy enough cat food for her cat.
Dominic is going to drive from his house to City A without stopping. Dominic's house is 300 miles from City A and he plans to drive at a speed of 50 miles per hour. Write an equation for D, in terms of t,t, representing Dominic's distance from City A t hours after leaving his house.
Answer:
D= −50t + 300
Step-by-step explanation:
Since Dominic lives 300 miles from City A, when he starts his trip (at time
t=0), his distance from City A must be 300 miles, meaning D=300 when
t=0, which is the y−intercept.
(0,300) is a point on the graph
Since Dominic will drive 50 miles per hour, the Dominic's distance from City A decrease 50 miles for each hour of driving, making the slope of D equal to
−50.
Slope=−50
equation of the line: D= −50t + 300
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The equation for D, in terms of t, represents Dominic's distance from City A t hours after leaving his house.
D = 300 - 50t
Where t= number of hours
What is an equation?
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x = 4 is an equation.
We have,
Distance between Dominic's house and City A = 300 miles
Speed = 50 miles per hour.
The equation for D, in terms of t, represents Dominic's distance from City A t hours after leaving his house.
D = 300 - 50t
Where t= number of hours
Now,
We can see that,
At t = 1, D = 300 - 50 = 250 miles.
At t = 2, D = 300 - 100 = 200 miles.
Thus,
The equation for D, in terms of t, represents Dominic's distance from City A t hours after leaving his house.
D = 300 - 50t
Where t= number of hours

6x-2x=24 HELP PLSSSSSS
Answer:
x=6
Step-by-step explanation:
Basically since 6x and 2x have like terms you subtract the 2x from 6x.
6x-2x=4x
Then you divide 4 from 24.
4x=24
4x/4 = 24/4
x=6
Answer:
6x - 2x = 24
4x = 24
4x ÷ 4 = 24÷4
x = 6
Step-by-step explanation:
First of all subtract 2x from 6x which will give you 4x = 24
since you're finding x or want to make x the subject you are to divide both sides by 4, so
4x ÷ 4 will give you x, since both 4's will cancel out giving you x =, then you divide 24 by 4 also. 24 ÷ 4 will give you 6, so x = 6.

6a+5a=-11
Multi step equations
Show worm
Answer:
a = -1
Step-by-step explanation:
First, combine like terms. Like terms are terms with the same amount of the same variables.
6a + 5a = -11
(6a + 5a) = -11
(11a) = -11
Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Divide 11 from both sides:
(11a)/11 = (-11)/11
a = -11/11
a = -1
a = -1 is your answer.

For spirit week at a local high school, students were encouraged to wear their school colors of green and white. 1,200 students wore their school colors while 300 students did not wear green and white. What percent of the school population wore their school colors?
Answer:
80%
Step-by-step explanation:
We are told that 1,200 students wore their school colors of green and white.
Also, we are told that 300 students did not wear school colours green and white.
Thus, total number of students = 1200 + 300 = 1500
Thus;
percent of the school population who wore their school colors is; (1200/1500) × 100% = 80%
marco is 6 feet 3 inches tall. There are 2.54 centimeters in 1 inch. What is marcos height in centimeters.
Answer:
Hi
Step-by-step explanation:
Answer:
The answer is 190.5cm
Step-by-step explanation:
so solve this problem, we first need to convert marco's height to inches.
there are 12 inches in 1 foot.
multiply.
[tex]\frac{6ft}{1} *\frac{12inch}{1ft} \\72inch[/tex]
notice how ft cancel out because they are in opposite positions of the fraction.
add 72+3 to get marco's height in inches.
[tex]72+3\\75[/tex]
marco is 75inches.
with this information, we can solve for his height in cm.
write an equation.
[tex]\frac{75inch}{1} *\frac{2.54cm}{iinch}[/tex]
solve.
[tex]\frac{75inch}{1} *\frac{2.54cm}{iinch}\\190.5cm[/tex]
marco is 190.5centimeters

Step-by-step explanation:
During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by the equation s = 10│x - 4│+ 50 where s represents the sound level in decibels and x represents the number of measures of music played. At what number(s) measures played would the sound level be at 80 decibels?
Answer:
The sound level would be at 80 decibels at 1 or 7 number of measures played
Step-by-step explanation:
Equations with Absolute Values
We have the function s to represent the sound level in decibels:
[tex]s = 10|x - 4|+ 50[/tex]
Where x is the number of measures of the music played.
We are required to find the value of x that makes s=80 decibels. We have to find the equation:
[tex]10|x - 4|+ 50 =80[/tex]
Subtracting 50:
[tex]10|x - 4| =80-50[/tex]
[tex]10|x - 4| =30[/tex]
Dividing by 10:
[tex]|x - 4| =30/10=3[/tex]
[tex]|x - 4| =3[/tex]
For the absolute value be equal to 3, its argument could be positive or negative:
[tex]x-4=3[/tex]
Or
[tex]x-4=-3[/tex]
This leads us to two solutions:
[tex]x=3+4=7[/tex]
x=7
Or
[tex]x-4=-3[/tex]
[tex]x=4-3=1[/tex]
x=1
The sound level would be at 80 decibels at 1 or 7 number of measures played

Combine like terms which are 4xy and 2xy
6xy+x
Answer:
6xy + x
Step-by-step explanation:
This is the answer because:
1) First, look at all the combine terms
Combine Terms: 4xy and 2xy
2) Since we have a + sign, we have to add 4xy + 2xy which equals 6xy
3) Finally, we are left with 6xy + x
Therefore, the answer is 6xy + x
