12x+6y= 24

Move +6y to the other side. Sign changes from +6y to -6y

12x+6y-6y= 24-6y

12x= 24-6y

divide by 12

12x/12= 24/12-6y/12

x= 2-1/2y

Answer: Od. x=2-1/2y

The length of an object object in feet is equal to 3 times it’s linked in yards the length of wall water side slide is 48 feet r

-BARSIC- [3]

<h3><u>Question:</u></h3>

The length of an object in feet is equal to 3 times its length in yards. The length of a waterslide is 48 feet. Write and solve a multiplication equation to find the length of the waterslide in yards.

<h3><u>Answer:</u></h3>

The length of waterslide is 16 yards

<h3><u>Solution:</u></h3>

Given that,

The length of an object object in feet is equal to 3 times it’s length in yards

The length of wall water side slide is 48 feet

Let "y" be the length of object in yards

Write and solve a multiplication equation to find the length of the waterslides in yard

From given,

Length in feet = 3 times length in yards

$48 = 3 \times y$

<em><u>Therefore, the multiplication equation is:</u></em>

$3y = 48$

Solve the equation for "y"

Divide both sides of equation by 3

$\frac{3y}{3} = \frac{48}{3}\\\\y = 16$

Thus length of waterslide is 16 yards

Jack says 0.90 is between 0.9 and 0.91. Is he correct? Explain.

OleMash [197]

Well, 0.90 is actually equal to 0.9. It is less than 0.91 and equal to 0.9 so that means it is not correct.

I hope this helps:)

Rex weighed 80 pounds a year ago. Now he weighs 92 pounds. What is the percent increase in his weight?

bezimeni [28]

So base on the question, that states the weight of Rex from last year to the present, and find its rate if change or percentage of change. To calculate the percentage you must first subtract the said weight in the present to its past then divide it by its past weight then multiply it by 100. So the percentage would be 15 %. I hope this would help

Need help solving for X

artcher [175]

X+10=110-4x

-x from both sides

10=110-5x

subtract 110 from both sides

-100=-5x

divide both sides by -5

x= 20
