An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triangle is x. Another side is 9 more than four times the length of the bottom of the triangle. The last side is 11 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle.
What is the expression for the perimeter of the triangle?
Answer:
perimeter = 6x + 15
Step-by-step explanation:
The perimeter of the triangle is the distance around the triangle.
We need to apply our ability to convert word problems in to mathematical expressions.
We were told that the bottom of the triangle is x units.
From the diagram perimeter 4x + 12 + x + 3 + x = 6x + 15
Four times the length of the bottom will be 4x .
12 more than 4 times the bottom will be 4x + 12.
Hence another side of the triangle is 4x + 12.
Finally we were told that the last side is 3 more than the bottom, that will be x + 3.
Answer:
I think the peremeter is 6x+15

B equals 19
Use the sentence stem: The triangle is/ is not a right triangle because____ squared + _____ squared does/does not equal _____ squared.
Answer:
The triangle is NOT a right triangle because (a or 20) squared + (b or 48) squared does NOT equal (c or 54) squared.
Step-by-step explanation:
a squared + b squared = c squared
the two shortest sides are a and b
20^2 + 48^2 = 54^2
400 + 2304 = 2916
2704 = 2916
Plz help me on 8 and 9 plz answer and give and explanation I am supposed to show my work
Answer:
8) the ordered pair is a solution, 9) the ordered pair is not a solution
Step-by-step explanation:
8) if you plug in the values of x into the equation, which is 7, 7+9 equals to 16, which is the y value in the ordered pair
9) the same is for this question, if you plug in the x value into the equation, which is 5, 2(5)+8 is equal to 10+8 which is equal to 18. This isn't equal to the y value in the ordered pair
Answer:
8.) yes it is a solution because if plug in 7 for x and 16 for y you get 16=7+9 which equals 16
9.) No it is not a solutions because if you plug in 28 for y and 5 for x you 28=2(5)+8 and then when you multiply the 2 and the 5 you get 28=10+8 and 10+8 equals 18 and 28 and 18 are not equal
I hope this helped! :)))

The town recreation department ordered 100 balls and bats for the summer baseball camp. Balls cost $4.50 each, and bats cost $20. 00 each. They spent $822.00 . How many of each item, bats and balls, were purchased.
Answer:
76 balls and 24 bats
Step-by-step explanation:
Set up a system of equations where x is the number of balls and y is the number of bats:
x + y = 100
4.5x + 20y = 822
Solve by elimination by multiplying the top equation by -20, then combine the equations together:
-20x - 20y = -2000
4.5x + 20y = 822
-15.5x = -1178
x = 76
Then, plug in 76 as x in the first equation to solve for y:
x + y = 100
76 + y = 100
y = 24
So, 76 balls and 24 bats were purchased.

Are these ratios equivalent? 18 : 45 and 2 : 6
Answer:
No, six multipled by nine is not 45
Step-by-step explanation:
Happy holidays
No, the given ratios 18 : 45 and 2 :6 are not equivalent.
Are these ratios equivalent? 18 : 45 and 2 : 6, To be justified.
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Example 9 / 4 , 4 / 8 , 9 : 2 , a : b ratios of volumes, volume of cirlce : volume of square.
Here,
18 : 45 = 18 / 45
=18 / 45
18 and 45 have common lowest multiple of 9 so
= 2 * 9 / 5 * 9
= 2 / 5
Here, 2 / 5 is not equivalent to 2 / 6 so it would be said that 18/45 is not the equivalent ratio to 2 : 6.
Thus, No, the given ratios 18:45 and 2 : 6 are not equivalent.

Answer:
A) 4(7+x)=64
B) 4x+7=64
Step-by-step explanation:
A
4(7+x)=64
*Disturabute 4 to (7+x)*
28+4x=64
*Subtract 28 on both sides*
4x=36
*Divide by 4*
x=9
