What is the value of x

Answer:

brainlest maybe

Step-by-step explanation:

Nature's Best wants to combine nuts they sell for $3.60 a pound with dried fruit they sell for $2.40 a pound to create a trail mix. How much of each snack should they use to make 10 pounds of trail mix that would sell for $3.30 a pound?

--------------

Let amt. of nuts be "x" lbs ; value is 3.60x dollars

-------------

Amt of fruit is "10-x" lbs ; value is 2.4(10-x) = 24-2.4x dollars

----------------------

Amt of mix is 10 lbs ; value is 3.3*10= 33 dollars

------------------------

EQUATION:

value + value = 33 dollars

3.6x + 24-2.4x = 33

1.2x = 9

x = 7.5 lbs (amt of nuts in the mix)

10-x = 2.5 lbs (amt of fruit in the mix)

present age of charlie is  45 years

present age of priya is  25 years

Step-by-step explanation:

Let start from five years ago

Let at that age of Priya was x years

given that

Charlie was twice older than Priya

age of Charlie = 2x

_____________________________________________

present age of charlie = age 5 years ago + 5 years = 2x + 5

present age of priya = age of priya  5 years ago + 5 years x + 5 = x + 5

_________________________________________________

age of charlie 3 years from now = present age of charlie + 3 years

age of charlie 3 years from now =2x + 5 + 3 = 2x + 8

age of priya 3 years from now = present age of priya + 3 years

age of priya 3 years from now =x + 5 + 3 = x + 8

Given that

in 3 years the sum of their ages will be 76

thus

sum of their ages in 3 years from now = x + 8 + 2x + 8 = 76

=> 3x + 16 = 76

=> 3x = 76-16 = 60

=> x = 60/3 = 20

Thus,

present age of charlie =  2x + 5 = 2*20 + 5 = 45 years

present age of priya = x + 5 = 20 + 5 = 25 years

Answer:

31 pounds

Step-by-step explanation:

From the information given, you can write the following formula to calculate the total cost of sending gifts:

Total cost of sending gifts=2.50+0.85x, where x is the weight of the gifts in pounds

Also, you know that the total cost of sending gifts is $28.85 and you can replace this value and solve for x:

28.85=2.50+0.85x

28.85-2.50=0.85x

26.35=0.85x

x=26.35/0.85

x=31

According to this, the answer is that the gifts weighed 31 pounds.

Answer:

B

Step-by-step explanation:

to find this, we can isolate y.

x+y=11

y=11-x

y=-x+11

Answer:

negative 5 over 32 degrees Fahrenheit

Step-by-step explanation:

Given the following :

Change in temperature per day = (- 5/32)°F

Waht will be the change in temperature after 3 days :

(-5/32)°F × 3 = ( - 15/96)°F

-15/96 = (-5/32)°F

Hence, the change in temperature will be :

negative 5 over 32 degrees Fahrenheit

Answer:

Yes

Step-by-step explanation:

The line of best fit is used in linear regression models to make predictions, the line of best fit gives the relationship between the dependent and independent variables by obtaining the Coefficient of correlation. The Coefficient of correlation is a value which ranges from - 1 to 1. With values close to either - 1 or 1 depicting a strong negative and positive relationship respectively. Hence, with a correlation Coefficient of - 0.86, which signifies a strong negative relationship, then we can go ahead and make prediction using the model.

Explanation:

4x+3y=37

y=x-4

4x+3(x-4)=37

4x+3x-12=37

add 12 to both sides

7x=49

x=7

Now you use plug in x

4(7)+3y=37

28+3y=37

subtract 28 to both sides

3y=9

y=3

answer: x=7 and y=3

Answer:

1) Find the measure of each angle.

The measure of each angle = 63° and 27°

2) Which equation below accurately translates the sentence and could be used to find the measure of each angle?

a) 2x + 9 = 90 - x

Step-by-step explanation:

1) Find the measure of each angle.

Two Angles are Complementary when they add up to 90 degrees (a Right Angle)

Mathematically this is represented as:

x° + y° = 90°

From the above question, we are told that:

The measure of an angle is 9 more than twice its complement.

Let the complement of an angle be represented by x

And its measure of an angle be represented by y

Hence,

y = 2× x+ 9

y =(2x + 9)°

x° + y° = 90°

Substitute 2y + 9 for x

x + 2x + 9 = 90

Collect like terms

x + 2x = 90 - 9

3x = 81

Divide both sides by 3

3x/3 = 81/3

x = 27°

We find y(measure of the angle)

x + y = 90

27 + y = 90

y = 90 - 27

y = 63°

Therefore, the measure of each angle is given as:

Measure of an angle = 63°

Complement of an angle = 27°

2) Which equation below accurately translates the sentence and could be used to find the measure of each angle?

a)2x + 9 = 90 - x

b) x + 9 = 2(x - 90)

c) x = 9 + 2(90 - x)

d) 2x = (x - 90) + 9

Option a) is the correct option

Answer:

6 games and 3 rides

Step-by-step explanation:

Let the number of games Brianna played be x,

and the number of rides she went on be y.

Total cost for games= 1.25x

Total cost for rides= 3.75y

Since number of games is twice the number of rides,

x= 2y -----(1)

Total costs= cost of games +cost of rides

[tex]18.75= 1.25x +3.75y[/tex]

Multiply the whole equation by 4 to remove the decimals:

[tex]75= 5x +15y[/tex]

Simplify by dividing the whole equation by 5:

[tex]15 = x + 3y[/tex]

Label the equation:

x +3y= 15 -----(2)

Although we can solve these 2 equations by substitution, since the question requires us to graphically solve, we have to graph 2 linear lines.

I will choose 3 points to plot on the graph for each equation:

x= 2y -----(1)

[tex]\begin{tabular}{|c|c|c|c|}

\cline{1-4}x & 2(1) = 2&2(2) = 4&2(3) = 6\\

\cline{1-4}y & 1 &2&3\\

\cline{1-4}

\end{tabular}[/tex]

x +3y= 15 -----(2)

x= -3y +15

[tex]\begin{tabular}{|c|c|c|c|}

\cline{1-4}x & -3(1)+15= 12& -3(2)+15= 9& -3(3)+15= 6\\

\cline{1-4}y & 1 &2&3\\

\cline{1-4}

\end{tabular}[/tex]

Let's plot these points on a graph paper. Then, join them with a straight line for each straight line graph. Please see the attached picture for the graph.

From (1): y= ½x

From (2): 3y= 15 -x

y= 5 -⅓x

From the graph, the solution of the equation is (6,3). The solution is the point on the graph in which the 2 lines intersect.

x- coordinate: 6

y- coordinate: 3

Thus, Brianna played 6 games and went on 3 rides.

Answer:

6 games=$7.5  3 rides=$11.25

1.25*6=7.5

3.75*3=11.25

7.5+11.25=18.75

Answer:

Step-by-step explanation:

you subtarct the 3 on both sides so it would be -6x=2

then you divide on both sides by -6 so it would look like x=-1/3

Answer:

x= -0.33 or -1/3

Step-by-step explanation:

What you have to do is isolate the x variable, you do the opposite to the other side of the equation to isolate the x.

Step 1- Subtract 3 to both sides of the equation.

-6x+3= 5

     -3  -3

-6x= 2

Step 2- Divide both sides of the equation by -6.

-6x= 2

 -6  -6

x= -0.3333...

So, x equals -0.333 or -1/3.
