Antonio completed the right column of the table to help him find the sum of 2/9 and 1/5. In which step did his first error occur?
Answer:
Step 1
Step-by-step explanation:
His first error occurred in step 1.
The common denominator of [tex] \frac{2}{9} [/tex] and [tex] \frac{1}{5} [/tex] is 45, and not 14.
Common denominator of both fractions, is a number of which both 9 and 5 are its factor. That is, it is a common multiple of 9 and 5.
45 can be divided by 9 without remainder. Also 45 can be divide by 5 without a remainder.
45 would make both fractions common not 14.

CAN YALL PLEASE HELP ME ❗️❗️❗️PLEASEEE
Answer:
1) intersection of both lines is the solution: (-3, 1)
2) y = -1/6x + 1 will produce a perpendicular line and intersect at only one point (slopes of 6 and -1/6 are opposite and reciprocal, thereby producing perpendicular lines)
3) 'b' can be any value except 1
Step-by-step explanation:
The property that says 2+3 is equivalent to 3+2
Please help me pleasee!
Answer:
3) (4, 2)
Step-by-step explanation:
The point of intersection of the lines is the solution. That point is (4, 2).
Answer: 3) (4, 2)
Answer:
the answer is the third one (4, 2)
Step-by-step explanation:
the solution to a system of equations is always where they intersect. in this case, the two lines intersect at (4, 2), which means that the solution is (4, 2).

El tripe de a edad de pedro mas 2 es igual a la edad actual de pedro mas 6. ¿Cuál es la edad actual de pedro?
Answer: Pedro tiene 2 años.
Step-by-step explanation:
Definamos la variable P como la edad de Pedro.
Sabemos que " El triple de la edad de pedro, más 2, es igual a la edad actual de pedro más 6"
Esto se escribe como:
3*P + 2 = P + 6.
Para encontrar la edad de Pedro, tenemos que resolver esa ecuación.
Para hacerlo, el primer paso es llevar todos los términos con "P" al lado izquierdo, y los términos sin "P" al lado derecho.
3*P - P = 6 - 2
2*P = 4
Ahora podemos dividir por 2 en ambos lados:
2*P/2 = 4/2
P = 2
Entonces podemos concluir que Pedro tiene 2 años.
What is the sum of the first five terms of the geometric series 3 − 6 + 12 − . . . ?
Answer:
33Step-by-step explanation:
The nth term of a geometric sequence is expressed as;
Sn = a(r^n - 1)/r - 1
a is the first term of the sequence
r is the common ratio
n is the number of terms
From the sequence;
a = 3
r = -6/3 = 12/-6 = -2
n = 5 (since are looking for the sum of first five terms)
Substitute into the formula;
S5 = 3((-2)^5 - 1)/-2 - 1
S5 = 3(-32-1)/-3
S5 = 3(-33)/-3
S5 = -(-33)
S5 = 33
Hence the sum of the first five terms of the sequence is 33

The ordered pair (1, -2) is a solution to the system of linear equations.
2x + y = 0
-x + 2y = 5
True
False
Answer:
False
Step-by-step explanation:
2x + y = 0
Try (1, -2)
2(1) + (-2) = 0
2 + (-2) = 0
0 = 0
The solution works on the first equation.
-x + 2y = 5
-(1) + 2(-2) = 5
-1 - 4 = 5
-5 = 5
The solution does not work in the second equation.
Answer: False

Answer:
SSS
Step-by-step explanation:
The SSS theorem is the side-side-side theorem. Basically, since all three sides from one triangle is congruent to the corresponding sides of the other triangle, then the triangles have to be congruent. There are other theorems such as the SAS theorem (side-angle-side), but since the question only give us the fact that the sides are congruent, its SSS. Sorry, I hope this is good enough. XD
Please send me a answer ASAP please thank you

A bracelet costs $39.59. It is marked down 25%.
What is the final price of the bracelet after it is marked down?
$9.90
$29.69
$35.49
$49.49
Answer:
$29.69
Step-by-step explanation:
Marked down 25% means it is now worth 75% of original value.
0.75*39.59 = $29.69
please give thanks by clicking the heart buton :) happy holidays
Answer:
$29.70
Step-by-step explanation:
$39.59 / 4 = 9.8975. Round up to 9.90
$39.59 - $9.90 = $29.69

A shareholders' group, in lodging a protest, claimed that the mean tenure for a chief executive office (CEO) was at least seven years. A survey of companies reported in the Wall Street Journal found a sample mean tenure of years for CEOs with a standard deviation of years. a. Formulate hypotheses that can be used to challenge the validity of the claim made by the shareholders' group. - Select your answer - - Select your answer - b. Assume companies were included in the sample. What is the -value for your hypothesis test
Complete question is;
A shareholders’ group, in lodging a protest, claimed that the mean tenure for a chief executive office (CEO) was at least seven years. A survey of companies reported in The Wall Street Journal found a sample mean tenure of x¯ = 7.27 years for CEOs with a standard deviation of s = 6.38 years (The Wall Street Journal, January 2, 2007).
a. Formulate hypotheses that can be used to challenge the validity of the claim made by
the shareholders’ group.
b. Assume 85 companies were included in the sample. What is the p-value for your hypothesis
test?
Answer:
A) Null hypothesis: H0: μ ≥ 7
Alternative hypothesis: μ < 7
B) p-value = 0.3488
Step-by-step explanation:
A) We are told that the shareholders group claimed that the mean tenure for a chief executive office (CEO) was at least seven years.
Thus, defining the hypothesis, we have;
Null hypothesis: H0: μ ≥ 7
Alternative hypothesis: μ < 7
B) Sample mean: x¯ = 7.27 years standard deviation: s = 6.38 years
Sample size = 85
Formula for the test static is;
t = (x¯ - μ)/(s/√n)
t = (7.27 - 7)/(6.38/√85)
t = 0.39
From online p-value from t score calculator attached using: t = 0.39, DF= 85 - 1 = 84, significance value = 0.05, one tail, we have;
p-value = 0.3488
