Let the first digit of the 2-digit number be x and the second digit be y.
Then the ratio (x/y) equals (1/2).  Write a formula for y in terms of x.

The tens digit is 2 more than the units digit.  Using the letters x and y, write out the proper equation.

Now solve your two equations simultaneously for x and y.

Scott burned 20 calories per minute jogging for x minutes and 5 calories per minute for biking for y minutes. He spent a total o
stiv31 [10]

Answer:

x = 112

Step-by-step explanation:

We can create two equations 1. one that calculates calories burned and 2.another that calculates minutes:

20*x + 5*y = 1200

x + y = 120

Then we can solve for x

x = 120 - y

then we can plug that into the top equation:

20(120 - y) + 5y = 1200

divide by 5:

4(120 - y) + y = 240

distribute:

480 - 4y + y = 240

and then do all that combining like factors what not and simplify and solve:

480 - 3y = 240

-3y = -240

y = 8

NOW WE CAN JUST PLUG IN THE ANSWER FOR Y TO FIND X

8+x =120

x = 112

<h3>Answer:  24 square meters</h3>

The notation "m^2" is a shorthand way of saying "square meters".

Chances are you'll simply type in the number and leave out the units, as that's already taken care of.

==========================================================

Work Shown:

area = base*height

area = 8*3

area = 24 square meters

---------

Explanation:

We simply multiply the base 8 and height 3 and that's our answer. It's not a trick question even if it might seem like it.

The side that's 7 meters long is never used. The base and height are always perpendicular to one another, which means that they form a right angle (aka 90 degree angle).

The area formula of a parallelogram and rectangle are the same. We can think of a non-rectangular parallelogram as a slanted rectangle in a sense. Imagine you had stacks of blocks to form a rectangle. Now imagine nudging that stack slightly to one side. The blocks themselves don't change, so the area of one wall doesn't change. All that's changed is the shape.

Brian was billed for 171 minutes.

Step-by-step explanation:

Given,

Monthly fee of phone = $8

Charges per minute = 6 cents = $0.06

Last month bill of phone = $18.26

Let,

x be the minutes billed.

Therefore,

Monthly fee + 0.06*minutes = Total bill

8+0.06x=18.26\\0.06x=18.26-8\\0.06x=10.26

Dividing both sides by 0.06

\frac{0.06x}{0.06}=\frac{10.26}{0.06}\\x=171

Brian was billed for 171 minutes.
