Answer:
x = 18
These two angles are formed by a transversal that cuts through 2 parallel lines. This means that (5x + 2) on line m corresponds to the angle on the right of (5x-2) on line n.
Now that we can see (5x + 2) and (5x - 2) are on a straight line, we can say that (5x + 2) + (5x - 2) = 180
10x + 0 = 180
10x = 180
x = 180/10
x = 18

The costume jewelry and accessories for the show are bought from sales racks at two different stores on different days. Use x to represent the price of each item on the sales rack at the first store and y to represent the price of each item on the sales rack at the second store.
On the first day, the students spent $30 on 4 items from the first store and 7 items from the second store. On the second day, the students spent $22 on 3 items from the first store and 5 items from the second store. On the third day, the students need to buy 10 items from the first store and 17 items from the second store.
What is the amount of money the students will need on the third day? Find your answer by creating and solving a system of linear equations based on the first day and the second day. Explain your reasoning.
Answers
Answer:
74
Step-by-step explanation:
Using linear equations, we are given two equations from the questions:
4x +7y=30 from day one and 3x +5y=22 from day two
Multiply the first equation by 3 and second by 4 giving us
12x +21y=90 and 12x +20y=88. Minus both equations.
12x - 12x +21y - 20y= 90 - 88, Gives you y=2,
You can now use the value of y to find x.
4x + 7y = 30
4x + 7(2)= 30
4x + 14= 30. Minus 14 on both sides giving you
4x=16. Divide both sides by 4.
x=4
Now use both values to find how much money is needed on the third day.
10x + 17y
=10(4) + 17(2)
=40 +34
=74

Then divide everything by negative 2 and you have your answer
y=1/2x+1
-1x -1x
-2y=-1x-2
-2 -2 -2
y=1x+1

(The form is y=Mx+b so we want the y in front of the equation so we solve for x)
We divide -2 because we want the y isolated(aline and we want the y positive too)

Carrie has 0.125 more than Larry, Larry has 3/4 more than Harry. In total they have 151. How much does Harry have
Answers
Harry has 49.792 units.
Firstly we need to translate sentences into mathematical expressions and then we proceed to solve the resulting system of linear equations:
1) Carrie has 0.125 more than Larry:
[tex]y = x + 0.125[/tex] (1)
2) Larry has 0.75 more than Harry:
[tex]x = z + 0.75[/tex] (2)
3) In total, they have 151:
[tex]x + y + z = 151[/tex] (3)
Then, we proceed to solve the system of equations by direct substitution and clearing the remaining variable:
[tex]x + (x + 0.125) + (x-0.75) = 151[/tex]
[tex]3\cdot x -0.625 = 151[/tex]
[tex]3\cdot x = 151.625[/tex]
[tex]x = 50.542[/tex]
And the remaining solutions are, respectively:
[tex]y = 50.667[/tex], [tex]z = 49.792[/tex]
Harry has 49.792 units.
