Step-by-step explanation:
Remember, the sum of all the angles in a triangle equals 180 degrees.
Moreover, looking at the diagram, we can see sides BA and BC are identical. This means this triangle is an isosceles triangle. Remember, all isosceles triangles will also have two identical angles. In this case, angles A and C are identical (meaning A and C are both 73 degrees).
So, if A is 73 degrees, C is 73 degrees, and we know that all the angles must sum to 180 degrees (so A + B + C = 180), then we can construct the following equation to solve for x:
[tex]73+73+6x+4=180\\150+6x=180\\6x=180-150\\6x=30\\x=\frac{30}{6}\\x=5[/tex]

Find the value of x in each diagram
Answers
Answer:
A. x = 8.
B. x = 31.
C. x = 32.
Step-by-step explanation:
Here. the sum of the 2 parallel sides of the trapezoid = 2 * length of the middle line segment.
MN + RS = 2PQ
32+ x = 2*20
x = 40 - 32
x = 8.
MN + RS = 2PQ
20 + 42 = 2PQ
2x = 62
x = 31
MN + RS = 2PQ
22 + 42 = 2PQ
2x = 64
x = 32.

A box of cereal states that there are 72 calories in a 3 fourth cup serving what is the unit rate for calories per cup? HHow many calories are there in 4 cups? The unit rate is _ calories per cup
Answers
Answer:
4 cups = 384 calories ; 1 cup = 96 calories
Step-by-step explanation:
Given that:
3/4 cups = 72 calories
Let Number of calories in 4 cups = x
3/4 = 72
4 = x
Cross multiply
(3/4)x = 72 * 4
(3/4)x = 288
Multiply both sides by 4/3
(3/4 * 4/3)x = 288 * 4/3
x = (288 * 4) /3
x = 384
Hence, 4 cups has 384 calories
Number of calories per cup :
4 cups = 384 calories
1 cup = 384 / 4
1 cup = 96 calories

Cristian says that when you raise a base number to a power of 3, it is impossible for the number to get smaller. Do you agree or disagree? Justify (prove) your answer.
Answers
Answer: I disagree
Step-by-step explanation:
I disagree with the statement from Cristian. When you raise a base number to a power of 3, it is possible for the number to get smaller.
For example, let's say our base number is negative 2, that is -2. Now let's find the cube of the number. This will be:
= -2^3 = -2 × -2 × -2 = -8
In this example, we can see that -8 is smaller than -2. This shows that the statement by Cristian is not correct.

Melissa makes and sells necklaces and bracelets. One day she made a total of 28 pieces of jewelry. On this day the number of bracelets crafted was 4 more than twice the number of necklaces.How many of each type of jewlery did she make that day
Answers
Answer:
Number of necklaces = 8
Number of bracelets = 20
Step-by-step explanation:
Given that:
Mellisa is making and selling the necklaces and bracelets.
Number of pieces of jewelry made on one day = 28
Number of bracelets was 4 more than the twice the number of necklaces.
To find:
Number of each type of jewelry made = ?
Solution:
Let number of bracelets = [tex]b[/tex]
Let number of necklaces = [tex]n[/tex]
As per question statement:
[tex]b+n=28[/tex] ...... (1)
[tex]b = 2n+4[/tex] ...... (2)
Putting the value of [tex]b[/tex] in equation (1):
[tex]2n+4+n=28\\\Rightarrow 3n = 28-4\\\Rightarrow 3n = 24\\\Rightarrow n =\bold{8}[/tex]
By equation (1):
[tex]b + 8 =28\\\Rightarrow b = \bold{20}[/tex]
So, the answer is:
Number of necklaces = 8
Number of bracelets = 20
