Peter scored 151515 goals during his second soccer season as a forward. He scored 666 fewer goals during his first season. The team as a whole scored 444 times as many goals as Peter during the two seasons. How many goals did the team score during the two seasons?
Answer:
96
Step-by-step explanation:
Total goals scored by peter in second season = 15
In first season he was said to have scored 6 fewer goals. 15-6 = 9
The team as a whole scored 4times as much as peter did.
Let's call the total number of goals peter scored , T
So t = 15 + 9 = 24
4 times as much as peter = 4 x T
= 4x24
= 96 goals in both seasons were scored by the team.
Felicia is considering two companies for the installation of her new carpet. The carpet companies installation rates are shown.
Carpet Company A: C = 1.35y + 100 where c is the cost and y is the number of square yards.
Carpet Company B: This company charges $2.05 per square yard for the carpet and the installation.
Identity the unit rate in dollars per square yard for each carpet company.
Using linear function concepts, it is found that:
The unit rate for company A is of $1.35.The unit rate for company B is of $2.05.What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.For Company A, the equation is:
y = 1.35y + 100.
The slope is of m = 1.35, hence the unit rate is of $1.35.
For Company B, as already stated in the problem, the unit rate is of $2.05.

Step-by-step explanation:
if f(x)=2x+1, what would be the first step to find f(1)
Answer:
We are given a defined function: f(x) = 2x + 1. This function is the same as saying y = 2x + 1 (y and f(x) are used interchangeably and are the same value - just a different way of representing it). Because we want to find f(1), math states that if you replace one variable with a value, you must replace all of the same variables with that value. Because of this, if we change f(x) to f(3x), we are declaring that the variable x has a value of 3x. Or, if we were to change f(g) to f(3g + 4), we would then be replacing the g's in the function with 3g + 4.
Using these examples, we can the find the value of f(1). We would simply replace the x-values in the function with the value of 1 and then take any operations necessary - be sure to use PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
[tex]f(x) = 2x + 1\\\\f(1) = 2(1) + 1\\\\f(1) = 2 + 1\\\\f(1) = 3[/tex]
Therefore, the first step to solve the problem would be to replace the x-values in the equation with the value of 1. From there, you would simplify your equation and find what the value of the function is if evaluated at f(1).

Step-by-step explanation:
Because supplementary angles are either 2 angles where the sum equals 180, if we take 60 for [tex]\angle {1}[/tex], and then add it to [tex]\angle {2}[/tex], we get 2(60) = 120 for [tex]\angle 2[/tex] and 60 for [tex]\angle 1[/tex], meaning that if we add the values of both angles together, it will be 120 + 60 = 180.

Step-by-step explanation:
if you want to solve it would be 11/6, or "1 5/6ths"
we need to first find the common denominator, which is 6, but since we multiplied the bottom by 2, we multiply the top by 2. next we just subtract the values, and i put the 1 because there is only one "6" that goes in to the bottom ,and 5 is left over.

Three months later some vehicles were sold and new models have been brought into the Liberty Bike Shop. Now, there are a different number of bicycles, tandem bicycles, and tricycles in the shop. There are a total of 135 seats, 118 front handlebars (that steer the bike), and 269 wheels.
Answer:
There 68 bicycles , 33 tricycles and 17 Tandem bicycles
Step-by-step explanation:
Let B be the no. bicycles , TB be the no. of tandem bicycles and C be the no. of tricycles
No. of seats in 1 bicycle = 1
No. of seats in B bicycle = B
No. of seats in 1 Tandem bicycle = 2
No. of seats in TB Tandem bicycle = 2TB
No. of seats in 1 Tricycle = 1
No. of seats in C Tricycle = C
We are given that There are a total of 135 seats
So, B+2TB+C=135 ----1
Similarly
There are total 118 front handlers
So,1B + 1TB + 1C = 118 ----2
There are total 269 wheels
So,2B + 2TB + 3TR = 269
Substract 1 from 2
B+2TB+C-B-TB-C=135-118
TB=17
Adding 1 and 2 and substracting from 3
[2 - (1+1)]B + [2- (2+1)]TB + [3- (1+1)]C = 269-253
- 1x17 +C= 16
C= 16 + 17 = 33
Replacing in eq. 32
1B + 17 + 33 = 118
B = 118 - 17 - 33 = 68
Hence There 68 bicycles , 33 tricycles and 17 Tandem bicycles

Two numbers a and b are in the ratio 3 : 4. If the first number is decreased by 4 and the second is decreased by 2, they are in the ratio 2 : 3. Find a and b.
a =
b=
The value of a = 24 and b = 32. Let the original numbers be 3x and 4x since they are in the ratio 3 : 4.
Step 1: Form the new ratios after the given decreases.
The first number decreased by 4 becomes 3x - 4, and the second number decreased by 2 becomes 4x - 2. The new ratio is 2 : 3.
Step 2: Set up the equation based on the new ratios.
We have the following equation based on the new ratios:
(3x - 4) / (4x - 2) = 2 / 3
Step 3: Solve the equation for x.
To solve the equation, we can cross-multiply:
3(3x - 4) = 2(4x - 2)
Expand and simplify:
9x - 12 = 8x - 4
Now, isolate the variable on one side:
9x - 8x = 12 - 4
x = 8
Step 4: Find the values of a and b.
Now that we have the value of x, we can find the values of a and b:
a = 3x = 3 * 8 = 24
b = 4x = 4 * 8 = 32
So, a = 24 and b = 32.

Ralph is leasing a car worth $24,000 for three years. his leasing company says that the car ralph is leasing will only be worth $16,000 at the end of his lease. approximately what percentage of the car’s original value will ralph need to pay as part of his lease?
The percentage of the car's original value will be 33%
We have given that the car was worth $24,000, being this the original value, after three years the car will be worth $16,000.
Therefore to find the percentage of the car’s original value will Ralph need to pay as part of his lease, We have to find the difference between the original value and the new value.
So the difference between the original value and new value is,
24,000-16,000= $8000.
What is the percentage?A percentage is a number or ratio expressed as a fraction of 100.
And the percentage can be calculated dividing the difference by the original value of the car.

Solve 6x² +11x -35 =0
Step-by-step explanation: If you're asked to solve a quadratic equation by the method of your choice, you should always check to see if the quadratic factors before you try any other method.
In this case, we have a trinomial that
factors as the product of two binomials.
In the first position for each binomial, we will use
our factors of 6x² which are either 6x · x or 3x · 2x.
It's a good idea to try less extreme extreme factors.
That means choose factors a little closer together.
So 3x and 2x would be first on our list.
We do the same for the factors of -35.
Since our constant term is negative, it will factor
as the product of a positive times a negative.
So the factors of -35 are +7 · -5, -5 · +7, -7 · +5, +5 · -7.
Remember to reverse the order of the
factors is your lead coefficient is not 1.
The factors that work in this case are -5 and +7.
So we have (3x - 5)(2x + 7).
To check, take the product of the outer terms and inner terms.
So we have -21x + 10x which is our middle term.
Now set it equal to 0.
So we have (3x - 5)(2x + 7) = 0.
Now use the zero product property.
So either 3x - 5 = 0 or 2x + 7 = 0.
Solving each equation from here, we have x = 5/3 or x = -7/2.
