Evaluate x(y-z)2 for =-1,y=5,and z=
Nata [24]

Answer:

The value of x(y-z)^2 is -16.

Step-by-step explanation:

We need to evaluate x(y-z)^2 for x = -1, y = 5 and let us assume that z = 1

It can be simply done by putting the values of x,y and z in the given expression.

x(y-z)^2=(-1)(5-1)^2\\\\=-1(4)^2

We know that the value of 4² = 16

So,

x(y-z)^2=16\times -1\\\\=-16

So, the value of x(y-z)^2 is -16.

Complete Question

Tyler went to the supermarket to buy food for a food pantry. He has $36, and can carry up to 20 pounds of food in his backpack. Pasta costs $1 for a 1-pound package. Pasta sauce costs $3 for a 1.5 pound jar. Let x = the number of packages of pasta and y = the number of jars of pasta sauce. One package of pasta is the right amount to go with one jar of pasta sauce. What is the best numbers of packages of pasta and jars of pasta sauce to buy for the food pantry? Explain your reasoning.

Answer:

Eight is the best numbers of packages of pasta and jars of pasta sauce to buy for the food pantry.

Step-by-step explanation:

Let

x = the number of packages of pasta

y = the number of jars of pasta sauce.

He has $36, and can carry up to 20 pounds of food in his backpack. Pasta costs $1 for a 1-pound package. Pasta sauce costs $3 for a 1.5 pound jar.

x + 1.5y ≤ 20....... Equation 1

x = 20 - 1.5y

x × $1 + y × $3 = $36

x + 3y ≤ 36..... Equation 2

20 - 1.5y + 3y = 36

-1.5y + 3y = 36 - 20

1.5y = 16

y = 16/1.5

y = 8

And x = 8

Therefore,

Eight is the best numbers of packages of pasta and jars of pasta sauce to buy for the food pantry.

5x-(x+1)=5-2x i dont understand what to do. Plz help
Vlada [557]

Answer:

x=1

Step-by-step explanation:

5x-(x+1)=5-2x

distribute

5x-x-1 = 5-2x

4x-1 = 5-2x

add 2x on each side

4x-1+2x = 5-2x+2x

6x -1 = 5

add 1 on each side

6x-1+2 = 5+1

6x = 6

divide by 6

6x/6 = 6/6

x = 1

Hellllllllllllllllllllllllllllp!!!!!!!!!!!!!!!! will give brainliest
zavuch27 [327]

Answer:

Step-by-step explanation:

3in/4 = 0.75in(Diameter) for each circle

r = 0.375

A = πr^2

A(for 1 circle) = 0.141π

A(for 1/4 circle) = 0.035π

A x 4 because we have 4 circles =

0.141π

0.141π(area of middle) + 0.141π(area of circle) =

0.282π or 0.886in^2
