ANSWER QUICKLY!Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2, and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.

option 2 is better( 3 pizza with 30 inches diameter)

Step-by-step explanation:

Area of the large pizza = A=πr^2=962.11 * 2( for two pizzas)=1924.22

Area for small pizza : A=πr^2=706.86*3 pizza=2120.58

Answer:

The answer is A.

This is because adding 5 to both sides of the original equation gives us A.

An equivalent equation to 3r = 90 - 5 is 3r + 5 = 90

The correct answer is an option (A)

"It is a mathematical statement which consists of equal symbol between two algebraic expressions."

"The equations that have the same answer or solution."

For given question,

We have been given an equation 3r = 90 - 5

We know that the addition property of equality which states that  when the same quantity is added to both sides of an equation, the equation does not change.

⇒ 3r = 90 - 5

Add 5 on the both the sides of the equations.

⇒ 3r + 5 = 90 - 5 + 5

⇒ 3r + 5 = 90 + 0

⇒ 3r + 5 = 90

Therefore, an equivalent equation to 3r = 90 - 5 is 3r + 5 = 90

The correct answer is an option (A)

Answer:

The solution will be "x = 2 and x = -1".

Step-by-step explanation:

The given equation is:

⇒  [tex]2^{2x+2}\times 5^{x-1}=8^x\times 5^{2x}[/tex]

On solving "[tex]8^x[/tex]", we get

⇒  [tex]2^{2x+2}\times 5^{x-1}=(2^3)^x\times 5^{2x}[/tex]

As we know, if the base are same then their powers will be added together.

⇒  [tex]2x+2=3x[/tex] ...(equation 1)

⇒  [tex]x-1=2x[/tex] ...(equation 2)

From equation 1, we get

⇒  [tex]2=3x-2x[/tex]

⇒  [tex]2=x \ i.e., x =2[/tex]

From equation 2, we get

⇒  [tex]-1=2x-x[/tex]

⇒  [tex]-1=x \ i.e., x=-1[/tex]

So that the correct answer will be "x = 2" and "x = -1".

Answer:

x-14

Step-by-step explanation:

The binomial which is a factor of this trinomial is (x- 14).

An algebraic expression with three terms is called a trinomial.

Examples of a trinomial expression: x + y + z is a trinomial in three variables x, y and z.

Given:

p(x) = x²-16x + 28

If x+ a is factor of any polynomial p(x) then x= -a satisfy the polynomial.

factorizing p(x)

x²-16x + 28

= x²-14x + 2x + 28

= x( x- 14) + 2 (x+ 14)

= (x- 14)(x+ 2)

Hence, the binomial is (x- 14).

Answer:

Greta is correct. The answer is y = 4x

Step-by-step explanation:

This is because one person is able to plant four trees and five people are able to plant 20 in the same amount of time which means 4 trees is to 1 person. In other words if you substitute the values into the equation you will see that x = 1 in the first scenario and x = 5 in second scenario.I will work out the second scenario below.

y = 4x (where y = 20)

20  = 4(x)

[tex]\frac{20}{4} = \frac{4x}{4}[/tex]

5 = x

OR

y = 4x (where x = 5)

y = 4 * 5

y = 20

The equation which represents the number of trees planted y for the x number of people will be y = 4x thus Greta will be right.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

An equation is a set of variables that are constrained through a situation or case.

As per the given,

1 person plants 4 trees.

x = 1 and y = 4

y/x = 4

5 people plant 20 trees

x = 5 and y = 20

y/x = 20/5 = 4

y = 4x

Thus, y = 4x will be correct.

Hence "The equation which represents the number of trees planted y for the x number of people will be y = 4x thus Greta will be right".

Answer:

36.99 litros de combustible.

Step-by-step explanation:

En este problema debemos calcular el combustible total de consumió el camión, para eso debemos sumar el valor que consumió el día 1 más el valor que consumió el día 2, de la siguiente manera:

Consumo total = Consumo día 1 + Consumo día 2

Consumo total = 21.77 + 15.22

Consumo total = 36.99

Es decir que el consumo total del camión es de 36.99 litros de combustible.

Fill in the gap

From the question, we have that

mpg = Miles per gallon

[tex]mpg = \frac{Miles}{Gallon}[/tex]

Suppose a truck has 5 mpg;

This implies that the truck can travel 5 miles using 1 gallon

What if it's 4 mpg?

This implies that the truck can travel 4 miles using 1 gallon

What if it's x mpg?

This implies that the truck can travel x miles using 1 gallon

So, basically mpg represents the number of miles a truck can go for every unit of gallon

Jose's method

Distance on bus: 2.85 x 1000= 2850m

Total distance= 320m + 2850m

Distance to bus stop = 320 ÷ 100 = 0.32 km

Total distance= 0.32 km + 2.85 km

Answer:

63 cm

Step-by-step explanation:

piece 1: x

piece 2: x - 18

First you would subtract 2x - 18 = 108

Second you would add 108 + 18 = 2x

Third you would divide 126 divided by 2x = 63

So that would mean x = 63

Answer:

63cm

Step-by-step explanation:

2 pieces of rope, and one is shorter by 18cm.

piece 1: x

piece 2: x-18

Add the equations together, combine both pieces

2x-18

2x-18 = 108

108+18 = 2x

126 = 2x

x = 63

Answer : value of x and y in the matrix equation is:

x = -3

y = +4, -4

Step-by-step explanation :

The matrix expression is:

[tex]\left[\begin{array}{ccc}x+4\\y^2+1\end{array}\right]+\left[\begin{array}{ccc}-9x\\-17\end{array}\right]=\left[\begin{array}{ccc}28\\0\end{array}\right][/tex]

First we have to add left hand side matrix.

[tex]\left[\begin{array}{ccc}(x+4)+(-9x)\\(y^2+1)+(-17)\end{array}\right]=\left[\begin{array}{ccc}28\\0\end{array}\right][/tex]

Now we have to add left hand side terms.

[tex]\left[\begin{array}{ccc}x+4-9x\\y^2+1-17\end{array}\right]=\left[\begin{array}{ccc}28\\0\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc}4-8x\\y^2-16\end{array}\right]=\left[\begin{array}{ccc}28\\0\end{array}\right][/tex]

Now we have to equating left hand side matrix to right hand matrix, we get:

[tex]\Rightarrow 4-8x=28\text{ and }y^2-16=0\\\\\Rightarrow 8x=4-28\text{ and }y^2=16\\\\\Rightarrow x=-3\text{ and }y=\pm 4[/tex]

Therefore, the value of x and y in the matrix equation is -3 and +4, -4 respectively.

Answer:

D is wrong. The correct answer choice is C ( x=-3 and y= +4, -4)
