Kumar has twice the number of goals as Jacob. Make an algebraic expression. Plzzzz help
alekssr [168]

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

REWARDING 70 POINTS IN MATH TO THOSE WHO GET IT RIGHT<br> NO CHEATING ORELSE REPORTING
navik [9.2K]

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.

Lisa collects rainwater in a barrel that weighs 25 pounds. When there are 10 gallons of water in the barrel, the total weight of
Zinaida [17]

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

  • Δy is the change of y
  • Δx is the change of x

∵ 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 = \frac{83.4}{10}

∴ 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
