The algebraic expression is x = 2y where, "x" is the number of goals with Kumar and "y" is the number of goals with Jacob
<em><u>Solution:</u></em>
Given that Kumar has twice the number of goals as Jacob
To find: algebraic expression
An algebraic expression is a mathematical expression that consists of variables, numbers and operations
<em><u>Let us first define the variables</u></em>
Let "x" be the number of goals with Kumar
Let "y" be the number of goals with Jacob
Then from given statement,
Number of goals with kumar = twice the number of goals as Jacob
Number of goals with kumar = 2(number of goals with Jacob)
x = 2y
Thus the algebraic expression is found
Answer:
y = (2/3)x + 1.5
Step-by-step explanation:
To get our equation, we must first convert our values from inches to feet.
8/12 = 2/3 or 0.666667...
18/12 = 3/2 or 1.5
Now that we have our inches converted to feet, we can plug our values into the equation y = m(x) + b.

Answer:
The equation that matches this situation is y = 8.34x + 25 ⇒ B
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
- m is the slope (rate of change)
- b is the y-intercept (initial value)
The rule of the slope is m = Δy/Δx, where
∵ Lisa collects rainwater in a barrel that weighs 25 pounds
∴ The initial value of the weight is 25 pounds
∴ b = 25
∵ When there are 10 gallons of water in the barrel, the total weight
of the barrel and the water is 108.4 pounds
∴ At x = 10, y = 108.4
∵ When there are 20 gallons of water, the total weight is 191.8 pounds
∴ At x = 20, y = 191.8
→ Find Δx and Δy
∵ Δx = 20 - 10 = 10
∵ Δy = 191.8 - 108.4 = 83.4
→ Substitute them in the rule of the slope above
∴ m =
∴ m = 8.34
→ Substitute the values of m and b in the form of the equation above
∵ y = 8.34x + 25
∴ The equation that matches this situation is y = 8.34x + 25
