What is the value of X.
Answer:
x=5.25 or x=5 1/4
Step-by-step explanation:
These two angles are the same because they are vertical angles. We can write an equation to express this.
x+16=4x-5
Then solve.
x+16=4x-5
-x -x
16=4x-5
+5 +5
4x=21
x=5.25 or 5 1/4
7) -5x +6y = 16
3x - 7y = 4
A) (4, -2)
C) (-8,-4)
B) (4,2)
D) (2,-4)

A. 17x - 7
В. 17x+13
C. 10x
D. 30x
Answer:
A
Step-by-step explanation:
so the perimeter is the sum of all the sides which would be
(5x+1)+(6x-10)+(6x+2)
= 5x+1+6x-10+6x+2
=17x-7
which is A

Find the value of x
Answer:
x = 66
Step-by-step explanation:
Shapes with four sides are always 360 degrees
x + x - 20 + x + 40 + 2x + 10 = 360
combine like terms
5x + 30 = 360
subtract 30 from both sides
5x = 330
divide 5 from both sides
x = 66

5. Carlos and Mike are selling cheesecakes for a school fundraiser. Customers can buy pecan
cheesecakes and apple cheesecakes. Carlos sold 1 pecan cheesecake and 4 apple cheesecakes for a total
of $44. Mike sold 14 pecan cheesecakes and 14 apple cheesecakes for a total of $238. Find the cost
each of one pecan cheesecake and one apple cheesecake.
a. Define variables:
b. System:
c. Solve the systems (optional):
Answer:
One pecan costs $8. One apple costs $9.
Step-by-step explanation:
p and a are number of number of pecan and apple sold, respectively.
:::::
"1 pecan cheesecake and 4 apple cheesecakes for $44"
p + 4a = 44
"14 pecan cheesecakes and 14 apple cheesecakes for $238"
14p + 14a = 238
You have a system of two equations in two unknowns:
p + 4a = 44
14p + 14a = 238
:::::
Eliminate the p terms: Multiply the first equation by -14, then add the product to the second equation.
-14p - 56a = -616
14p + 14a = 238
------------------------
-42a = -378
a = (-378)/(-42) = 9
p = 44-4a = 8
One pecan costs $8. One apple costs $9.

The price of an item yesterday was $40. Today, the price fell to $22. Find the percentage decrease.
Answer:
45%
Step-by-step explanation:
40 * .45 = 18
40-18 = 22
The percentage decrease of an item would be 45%.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
We can determine the value of the percentage decrease by the following formula,
percentage decrease = (initial value - reduced value) / initial value × 100%
As per the given question, we have
initial value = $40, and reduced value = $22
Substitute the values in the above formula, and we get
percentage decrease = (40 - 22) / 40 × 100%
percentage decrease = (18) / 40 × 100%
percentage decrease = 0.45 × 100%
Apply the multiplication operation, and we get
percentage decrease = 45%
Thus, the percentage decrease of an item would be 45%.

there are 5 more than twice as many students taking Algebra 1 then taking algebra 2. If there are 44 students taking Algebra 2, what is the least number of students who could be taking Algebra 1? The least number of students is?
Answer:
93
Step-by-step explanation:
Key :
A1 = Algebra 1
A2 = Algebra 2
Alright so basically lets first look at the info they gave us :
We have 5 more than twice as many students taking A1 than we do A2.
We have 44 students taking A2.
And we need to find the least amount of students that could be taking A1.
So we need to take the amount of students taking A2 (44) and double it to find the amount taking A1.
So we can do 44 x 2 = 88 to get this.
But the problem also states there is 5 more then twice the number of students taking A2.
So we have that 88 but now we just need to add 5 to make up for them telling us that in the problem.
So :
88 + 5 = 93
Our final answer and least amount of students taking A1 is 93 students.
Answer:
93 students
Step-by-step explanation:
44 x 2 = 88
88 + 5 = 93

You need to use the Pythagorean Theorem twice.
First we have to find the diagonal for the base.
6²+8²=x²
36+64=x²
100=x²
√100=x
x=10
Now we can find d.
10²+3²=x²
100+9=x²
109=x²
√109=x
x=10.44 feet
If x = 0.75 and y = 0.6, find y when x = 5
Answer:
y = 4

create a proportion, then cross-multiply
0.6 / 0.75 = y / 5
5(.6) = .75y
3 = .75y
y = 3/0.75
y = 4
