A group of 195 students did a community service project.
The students took a total of seven cars and buses. Each
car holds 5 students and each bus holds 45 students.
Use substitution to solve the system of equations to
determine the number of cars, x, and the number of
buses, y they took. Express your answer as an ordered
Answer:
Step-by-step explanation:
x+y=7
x=7-y
So x=7-y
Put this in 5(7-y)+45y=195
35-5y+45y=195
35+40y=195
40y=195-35
40y=160
y=160/40
y=4

Write a polynomial in standard form with
zeros of 0 with a multiplicity of 2, and -1
Answer:
[tex]P(x)=x^3+x^2[/tex]
Step-by-step explanation:
Polynomials
Given the roots or zeros of a polynomial as x1, x2, x3, ...xn and the leading factor a, the polynomial can be expressed as:
[tex]P(x)=a(x-x_1)(x-x_2)(x-x_3)...(x-x_n)[/tex]
We are given the zeros of a polynomial as x1=0, x2=0 (multiplicity or zeros), and x3=-1, thus the polynomial is:
[tex]P(x)=a(x-0)(x-0)(x+1)[/tex]
Operating:
[tex]P(x)=a.x.x(x+1)[/tex]
[tex]P(x)=ax^2(x+1)[/tex]
[tex]P(x)=ax^3+ax^2[/tex]
Assuming a=1, the polynomial is

Enrique predicts that he can make additional money from sales of accessories and services for computer products sold by his store. The table at the right shows predicted percent returns for such sales. For example, if the store makes x dollars selling computer products, Enrique predicts the store will make 0.05x dollars from selling accessories. Part A In January and February of this year, the store made $2,500 from sales of accessories and services. Let x represent the amount the store will make from sales of computer products from March through December. Write an equation that represents the predicted amount y that the store will make from sales of accessories and services for the entire year. If Enrique predicts sales from accessories and services for the entire year will be $5,000, about how much money must be made from computer product sales from March through December? Explain.
Answer:
Following are the solution to this question:
Step-by-step explanation:
x was its full computer product revenue from March to December. In january and february, the revenue towards products and services before x quantities for computer product revenues will happen between March to December is $2,500.
Whenever x quantity is sold, then 0.05x quantity was sold for supplies and equipment.
The sum of accessories to sell should be calculated, indeed, year-round.
It helps us to split into two parts
y = accessory sales in January and February + accessories sales in March and December
Use item 2
y = $2,500 + March to December accessories sale
Now use sections 1 and 3
y = $2,500 + 0.05x
The above equation rewriting gives
y = 0.05x + $2,500 (a)
This formula is compared with a standard y = mx+c interrupt slope
We got a pitch of 0.05 and a pitch of $2,500.
In this soccer season Emma has scored one more than twice the number of Nikki's goals if Emma has scored 15 goals which equation can be used to find X number of goals
Answer:
[tex]X = 22[/tex]
Step-by-step explanation:
Given
Represent Emma with E and Nikki with N
From the question, we have that:
[tex]E = 1 + 2N[/tex]
and
[tex]E = 15[/tex]
Required
Determine the X number of goals
Substitute 15 for E in [tex]E = 1 + 2N[/tex]
[tex]15 = 1 + 2N[/tex]
Subtract 1 from both sides
[tex]15 -1 = 1 - 1 + 2N[/tex]
[tex]14 = 2N[/tex]
Divide both sides by 2
[tex]\frac{14}{2} = \frac{2N}{2}[/tex]
[tex]\frac{14}{2} = N[/tex]
[tex]7 = N[/tex]
[tex]N=7[/tex]
This implies that Nikki scored 7 goals in total
The X number of goals is then calculated as:
[tex]X = N + E[/tex]
[tex]X = 7 + 15[/tex]
[tex]X = 22[/tex]
SOPHIE gave 45% of her pocket money to AMELIE. SOPHIE now has £6.60. How much did SOPHIE have to begin with?
Answer:

Step-by-step explanation:
To find the original amount, divide 6.60 by 0.55:
6.60/0.55
= 12
So, Sophie had £12 to begin with
Find all real values of x that satisfy the equation x^2 - 7x = 98.
Answer:
-7, 14
Step-by-step explanation:
We start by writing this in the form $x^2 + bx + c = 0$, so we subtract 98 from both sides of the equation.
This gives us $x^2 - 7x - 98 = 0$. We proceed by factoring $x^2 - 7x - 98$, so we seek numbers that multiply to $-98$ and add to $-7$. We find that $7$ and $-14$ work.
Thus, our equation becomes $(x + 7)(x - 14) = 0$. We can now apply the fact that if the product of two real numbers is zero, then at least one of the real numbers must be 0.
Solving $x + 7 = 0$ and $x - 14 = 0$, we find that the solutions are $\boxed{x =-7~\text{and}~x = 14}$.
The value of the equation is given by x = 14 or x = -7
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
x² - 7x = 98 be equation (1)
Subtracting 98 on both sides of the equation , we get
x² - 7x - 98 = 0
Now , on simplifying the equation , we get
x² - 14x + 7x - 98 = 0
Taking x as the common factor of the equation , we get
x ( x - 14 ) + 7 ( x - 14 ) = 0
On further simplification , we get
( x + 7 ) ( x - 14 ) = 0
Now , the two solutions to the equation is
( x + 7 ) = 0
Subtracting 7 on both sides of the equation , we get
x = -7
( x - 14 ) = 0
Adding 14 on both sides of the equation , we get
x = 14
Therefore , the value of A is 14 or - 7
Hence , the equation x² - 7x - 98 = 0 has the solutions of 14 and -7
