The correct expression for "five times the sum of b and two" is determined by understanding the order of operations.
To represent "five times the sum of b and two" in an algebraic expression, we need to consider the order of operations. The phrase "the sum of b and two" indicates that we need to add b and two together first.
The correct expression is given by option c. (b + 2) * 5. This expression represents the sum of b and two inside the parentheses, which is then multiplied by five.
Option a, 5(b + 2), implies that only the variable b is multiplied by five, without including the constant term two.
Option b, 5b - 2, represents five times the variable b minus two, which is different from the given expression.
Option d is not provided, so it is not applicable in this case.
Therefore, the correct expression is c. (b + 2) * 5, which means five times the sum of b and two.

On a snorkeling trip, Dave dove at least 7 times as deep as Amy did. If Dave dove below 35 feet below the oceans surface, what was the deepest that Amy dove?
Answer:
The deepest that Amy dove below the ocean's surface is 5 feet.
Step-by-step explanation:
Let the deepest that Amy dove below the ocean's surface be x.
7x = 35
x = 5 ft
A family drinks 2 gallons of milk in 3 days,
At that rate, how many gallons will the family
drink in 15 days?
Answer: This is what I have tried --
5 gallons : 3 weeks = x gallons : 52 weeks
5/3 = x/52 (cross multiply)
3x = 260 (divide by 3)
x = 86.6 or 87 gallons
Step-by-step explanation: hope this is right
Answer:
10 gallons of milk
Step-by-step explanation:
This question is a ration every three days the family drinks 2 gallons of milk (3:2) to find how much they would drink in 15 days all you would have to do is multiple both numbers by 5 to get 15:10. This represents how much milk they drink in 15 days.

Step-by-step explanation:
20% of 17= 3.4
Add it to the initial $17 and you get $20.4
Answer: $20.40
Step-by-step explanation:
Since you're giving a 20% tip, your total will be 120% the price of the shampoo and cut.
17 * 120%
= 17 * 1.2
= 20.4
The total amount of money you spent at the salon and barbershop is $20.40

How to find the equation of linear regression?To find the regression equation, which is also called called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator.
The points in this problem are given as follows:
(12, 18), (9, 35), (14, 12), (8, 40), (10, 31), (4, 33), (18,10).
Inserting these points into the calculator, the line of best fit is given as follows:
y = -2.28x + 50.
When the value of y when x = 15 is given as follows:
y = -2.28(15) + 50
y = 15.8.

Write an equation of the line perpendicular to the given line that contains P.
Step-by-step explanation:
As the required line is perpendicular to y = (1/2)x + 5, product of slope of y = (1/2)x + 5 and required line should be - 1.
=> (1/2)m = - 1
=> m = - 2
Thus, required line is
=> y - (-8) = (-2)(x - 3)
=> y + 8 = -2(x - 3)

Which of the following represents the function f(x) = 5x^(2) + 20x + 25 in vertex form. Identify the vertex.
The function f(x) = 5x^2 + 20x + 25 can be rewritten in vertex form as f(x) = 5(x + 2)^2 + 5, and its vertex is located at (-2, 5).
To rewrite the function f(x) = 5x^2 + 20x + 25 in vertex form, we complete the square. The vertex form of a quadratic function is given by f(x) = a(x - h)^2 + k, where (h, k) represents the vertex.
Let's complete the square:
f(x) = 5(x^2 + 4x) + 25
To complete the square, we need to add and subtract (4/2)^2 = 4 to the expression inside the parentheses:
f(x) = 5(x^2 + 4x + 4 - 4) + 25
Rearranging the terms:
f(x) = 5((x^2 + 4x + 4) - 4) + 25
Now we can factor the perfect square inside the parentheses:
f(x) = 5((x + 2)^2 - 4) + 25
Expanding and simplifying further:
f(x) = 5(x + 2)^2 - 20 + 25
f(x) = 5(x + 2)^2 + 5
Therefore, the function f(x) = 5x^2 + 20x + 25 in vertex form is f(x) = 5(x + 2)^2 + 5. The vertex is given by the coordinates (-2, 5).
The correct question should be :
What is the vertex form of the function f(x) = 5x^2 + 20x + 25? Identify the coordinates of the vertex.

Need help
Answer:
∠ W = 51°
Step-by-step explanation:
Since WX is the diameter , then
∠ WYX = 90° ( angle in a semicircle )
The sum of the 3 angles in a triangle = 180° , then
x + x + 12 + 90 = 180
2x + 102 = 180 ( subtract 102 from both sides )
2x = 78 ( divide both sides by 2 )
x = 39
Then
∠ W = x + 12 = 39 + 12 = 51°
