Answer:
x=9
Step-by-step explanation:
FE is 3x-7
since ΔABC≅ΔDEF the equivalent of FE is CB, or BC...which is 20
3x-7=20
3x=27
x=9
Which two points on the number line are opposites? A number line going from negative 2 to positive 2 in increments of 1. There are 4 equal spaces between each number. Point A is 1 mark to the left of negative 1. Point B is half-way between negative 1 and 0. Point C is half-way between 0 and 1. Point D is half-way between 1 and 2. points A and B points B and C points C and D points A and D
Answer:
Points B and C are opposite
Step-by-step explanation:
0 on the number line marks the center of the number line. To the right on the number line are positive integers and to the left from zero are negative integers.
Points B and C are opposite because they are each half way between 0 and 1 on the right and 0 and -1 on the left
Answer:
b and c are opposites

Miguel made 6 identical necklaces each, having beads and a pendant. The total cost of the beads and the pendant for all 6 necklaces was $29.40. If the beads cost a total of $19.80, how much did each pendant cost?
Answer:
29.40-19.80=9.6
9.6/6=1.6
So the answer is $1.60

an equation of the line that passes through (3, 1) and (0, 10).
Answer:
So the equation of the line that passes through (3, 1) and (0, 10) is y=-3x+10
Step-by-step explanation:
(3, 1) and (0, 10)
m=y²-y¹/x²-x¹
m=10-1/0-3
m=9/-3
m=-3
y=mx+b
y-y=m(x-x1)
y-1=-3(x-3)
y-1=-3x+9
+1 +1
y=-3x+10
The Wells family goes out to eat dinner every Saturday night. Last Saturday was the 100th time the family had eaten at Happy Joe's Pizza House. The owner of Happy Joe's gave the family a 20% discount for customer loyalty. The bill was $27.50 before the discount. What was their bill after the discount?
b). Kirchoff has more money than Maxi. If Kirchoff gave Maxi $20, they would have the
same amount. While it Maxi gave Kirchoff $22, Kirchoff would then have twice as much as
Maxi. How much does each one actually have?
Answer:
k = 146
m= 106
Kirchoff has $146
Maxi has $106
Step-by-step explanation:
For the purpose of the equations, I’ll call Kirchoff and Maxi a and b respectively.
a - 20 = b + 20 (equation 1)
2(b - 22) = a + 22 (equation 2)
We can juggle those around for
a = b +40 (equation 1r (re-arranged)) and
2b - 44 = a + 22 so 2b - 66 = a (equation 2r (rearranged))
The equations are now:
a = b + 40 (new equation 1) and
a = 2b - 66 (new equation 2)
Substitute from new equation 1 to new equation 2:
b + 40 = 2b - 66 so 40 = b - 66 making b = 106.
Plug b = 106 into new equations 1 and 2 for:
a = 106 + 40 (new equation 1) and
a = 212 - 66 (new equation 2)
This gives a = 146 and b = 106
TEST: There’s a gap of $40, so giving $20 from a to b makes them equal.
SECOND TEST: Subtracting $22 from b makes it $84 and giving that sum to a makes it $168, twice as much. The tests work.
Kirchoff has $146 and Maxi has $106.

X-4y=15 and 8x-5y=42
Answer:
y=-2 8/9
x=31 1/2
Step-by-step explanation:
x-4y=15 --> x=4y+15
8x-5y=42
8(4y+15)-5y = 42
32y +120 - 5y = 42
27y = -78
y=-2 8/9
x=31 1/2

If you roll a number cube 60 times and use the results to calculate the experimental probability of rolling a 1, the experimental probability of rolling a 1 will _____ be less than the theoretical probability of rolling a 1.
Answer:
sometimes
Step-by-step explanation:
Theoretical probability is fixed/remains the same because it is based on theory which is calculated, while the experimental probability is based on data that is gained from actually doing it. According to the law of large numbers, the average experimental probability always approaches the theoretical probability.

Does anyone understand this and know what the answer is?
Answer:
y = -3x - 23
Step-by-step explanation:
When a transversal of the two lines is constructed, the alternate interior angles formed by the transversal are congruent. This means line m and n are parallel to each other so their slope will be the same.
Given:
line m: y = -3x + 8 <======= slope is -3
line n going through point (-4, -11) with same slope as line m:
y = mx + b
(-11) = -3(-4) + b
-11 = 12 + b
b = -23 <===== y-intercept of line n
Use the above slope and y-intercept to form equation of line n:
y = mx + b
y = -3x - 23

Multiply the polynomial x (3x-1)(2x+5) also what is the degree of the polynomial
Answer:
Result after multiplication of polynomial is: [tex]6x^3+13x^2-5x[/tex]
Degree of polynomial = 3
Step-by-step explanation:
The given polynomials are:
[tex]x(3x-1)(2x+5)[/tex]
In order to multiply the given polynomials we have to work step by step. First of all the polynomials in the bracket will be multiplied and then their result will be multiplied with x.
So, multiplying the polynomials in round brackets first
[tex]=x(3x-1)(2x+5)\\= x\{3x(2x+5)-1(2x+5)\}\\=x\{6x^2+15x-2x-5\}\\=x(6x^2+13x-5)[/tex]
Now multiplying with x
[tex]= 6x^3+13x^2-5x[/tex]
Degree of a polynomial is the highest exponent of variable in the polynomial.
In the acquired result, the highest exponent of x is 3 so the degree is 3.
Hence,
Result after multiplication of polynomial is: [tex]6x^3+13x^2-5x[/tex]
Degree of polynomial = 3
At the science fair, Christine uses 8 fluid ounces of vinegar to make her volcano erupt. How many times can she make her volcano erupt with 1 quart of vinegar?
Answer:
1 quart gives 32 ounces. And you already know how many ounce are needed to erupt. So the last step you can figure out easily.
Give brainiest.
Christine can make her volcano erupt 4 times because 8 fluid oucens equals 1 cup and there are 4 cups in one quart.
