A group of friends are at a baseball game and are purchasing souvenirs. Olivia purchased 1 t-shirt and 5 baseball caps, spending a total of $165. Her Marco purchased 1 t-shirt and 4 baseball caps, which cost him a total of $137. Assuming that all of the t-shirts and all of the caps are the same price, what is the price of each?
Answer:
baseball cap = $28
t-shirt = $25
Step-by-step explanation:
Olivia: t +5b = 165
Marco: t + 4b = 137
isolate t in Olivia's equation
t = 165 - 5b
plug t into Marco's equation
165 - 5b + 4b = 137
165 - b = 137
b = 28
plug b into either equation
t + 4b = 137
t + 4(28) = 137
t + 112 = 137
t = 25

The solution of the equation is 17.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given an equation as;
(5x+17)+129+94+(7x-46)+(9x-11)=540
Solving;
5x+7x+9x+17+129+94-46-11=540
21x+146+94-57=540
21x+240-57=540

An equation of a line that goes through -1/-3 and is parallel to the line 6x - y =1
Answer:
y=6x+3
Step-by-step explanation:
1.6x-y=1 solve for y
-y=-6x+1 divide bot sides by -1
y=6x-1
slope is 6
the slopes of parallel lines are equal
y-(-3)=6(x-(-1))
y+3=6(x+1)
y+3=6x+6

sixty-eight percent of valley creek school students attend this year's homecoming dance if 459 students attend the dance how many students are in the school?
The total number of students in the school will be 675.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that sixty-eight per cent of valley creek school students attend this year's homecoming dance if 459 students attend the dance.
The number of students will be calculated as,
68% ⇒ 459
1% ⇒ 459 / 68
100% ⇒ (459 x 100 ) / 68
100% ⇒ 675 students
Therefore, the total number of students in the school will be 675.
