"I am 3 times as old as Sue is," Frank said to Ann. "On the other hand, I am 15 years older than John while Sue is 1 year younger than John. How old am I?"
If J represents John's age, then which of the following equations could be used to solve the problem?
J + 15 = 3J - 1
J + 15 = 3(J - 1)
Answer:
J + 15 = 3(J - 1)

How do I solve this equation?
Answer:
x=7,x=-4
Step-by-step explanation:
[tex]2x-3=11\\2x=11+3\\2x=14\\x=7\\\\2x-3=-11\\2x=-11+3\\2x=-8\\x=-4[/tex]
Answer: x=7, x= -4
Step-by-step explanation: Ok because of the absolute value signs, there are going to be two different equations. The first one is just 2x-3=11. Solve that: 2x=14, x=7. Then because the answer in the absolute value could also be -11 (because absolute values always have to be positive), there is another equation : 2x-3=-11. Add 3 on both sides, 2x=-8, x=-4

Data with a correlation coefficient of 0.05 has a _[blank A]_ correlation, and data with a correlation coefficient of −0.80 has a _[blank B]_ correlation.
Answer:
Correlation Coefficient r value of 0.05 means a weak or very weak positive relationship while
Correlation Coefficient r value of 0.80 means a strong positive relationship
Step-by-step explanation:
Correlation Coefficient (r) signifies the strength of relationship which exists between two linear variables. The value of r ranges from - 1 to + 1 where positive and negative values signifies a positive and negative relationship relationship respectively.
The closer the r value is to either +1 or - 1, the greater the strength of the relationship while a r value of 0 means, there is no relationship between the two variables.
Hence in the scenario above :
Correlation Coefficient r value of 0.05 means a weak or very weak positive relationship while
Correlation Coefficient r value of 0.80 means a strong positive relationship
Answer:
Step-by-step explanation:
Correlation Coefficient r value of 0.05 means a weak or very weak positive relationship while
Correlation Coefficient r value of 0.80 means a strong positive relationship

Are the numbers of white and yellow flowers in Cara’s arrangements proportional? Write an equation that relates the number of yellow flowers, y, to the number of white flowers, w.
Part B
Are the numbers of white and yellow flowers in Hector’s arrangements proportional? Write an equation that relates the number of yellow flowers, y, to the number of white flowers, w.
Answer:
Step-by-step explanation:
15
Part A:
Yes, the numbers of white and yellow flowers in Cara's arrangements are proportional.
yellow flowers = y
white flowers = w
5y = 3w
Therefore, the numbers of white and yellow flowers in Cara's arrangements are proportional.
Part B:
yellow flowers = y
white flowers = w
6y = 4w
Therefore, the numbers of white and yellow flowers in Hector's arrangements are proportional.

Imani and Todd were trying to solve the equation: x^2+6x+5=8x 2 +6x+5=8x, squared, plus, 6, x, plus, 5, equals, 8 Imani said, "I can factor the left-hand side into (x+1)(x+5)(x+1)(x+5)left parenthesis, x, plus, 1, right parenthesis, left parenthesis, x, plus, 5, right parenthesis, so I'll solve using the zero product property." Todd said, "I can solve by completing the square. If I add 444 to each side, I can rewrite the equation as (x+3)^2=12(x+3) 2 =12left parenthesis, x, plus, 3, right parenthesis, squared, equals, 12." Whose solution strategy would work? Choose 1 answer: Choose 1 answer:
Answer:
Todd's
Step-by-step explanation:
Given the expression x^2+6x+5=8, we are to determine which whether Imani or Todd method will work
Imani method might not work because he hasn't written the equation in standard form before factorizing. He should have equated the expression to zero first before factorizing and finding the zeros of the expression. The equation should have been written in the form ax²+bx+c = 0 first.
For Todd, his method will work because he used the completing the square method. The value at the right hand may not necessarily be zero before applying the rule. The idea is to make the quadratic equation complete and a perfect square.
This is achieved by adding the half of coefficient of x to both sides of the expression before simplifying.
From the expression x²+6x+5 = 8 we can see that adding 4 to both sides will make the quadratic equation on the left a perfect square.
x²+6x+5= 8
x²+6x+5+4= 8 +4
x²+6x+9 = 12
x²+3x+3x+9 = 12
x(x+3)+3(x+3) = 12
(x+3)(x+3) = 12
(x+3)² = 12
We can see that the expression at the left hand is now a perfect square. Hence Todd solution strategy will work

PLEASE HELP 3x – 7 ≥ 4x + 2
Hi there!
[tex]\large\boxed{x \leq -9}[/tex]
3x - 7 ≥ 4x + 2
Subtract 3x from both sides:
3x - 3x - 7 ≥ 4x - 3x + 2
-7 ≥ x + 2
Subtract 2 from both sides:
-7 - 2 ≥ x + 2 - 2
-9 ≥ x
x ≤ -9
If a van traveled 120 miles in 2 hours, how far could the van travel in 5 hours?
Answer :
The Answer Is 300 Miles In 5 Hours

The diagram shows a sector of a circle radius 11 cm.
Show that the perimeter of the sector
is greater than 47.5 cm.
135°
11 cm
Answer:
Perimeter of sector is 47.93 cm which is greater than 47.5 cm
Step-by-step explanation:
Mathematically, the perimeter of a sector is length of the arc plus 2 radii
The length of the arc is;
theta/360 * 2 * pi * r
where theta is the angle subtended by the arc at the center of the circle
Thus, we have
135/360 * 2 * 22/7 * 11 = 25.93
Add 2 radii = 25.93 + 2(11) = 47.93 cm
This is greater than what we are asked to calculate and thus we have shown what we are asked to show
Answer:
47.9cm>47.5cm
Step-by-step explanation:
135(angle) /360 x 2 pi r (to give arc of the sector)
135/360 x 2 x 3.142 x 11 = 25.92cm
add 11 + 11 (radius)
25.92 + 22= 47.9cm

−3(x + 3) = −3(x + 1) − 5
Answer:
No real solutions
Step-by-step explanation:
Distribute the -3
-3x - 9 = -3x -3 -5
-3x - 9 = -3x - 8
add 3x to both sides
-9 = -8
makes it no real solution
Evaluate the expression -8x + 5 - 2x - 4 + 5x when x = 2 before and after simplifying.
Answer:
Step-by-step explanation:
all we have to do is plug in 2 for x into the equation:
-8(2) + 5 -2(2) -4 + 5(2)
-16 + 5 -4 -4 + 10
-11 -8 + 10
-19 + 10
the answer is
-9
to simplify the equation we’ll combine like terms
-8x + 5 -2x -4 + 5x
-10x + 1 + 5x
-5x + 1
now we’ll plug in 2 for x
-5(2) + 1
-10 + 1
the answer is still
-9
Answer:
-9
