I think it is 640..  What they mean is every inch equals 4 feet so you would multiply 8*4 and 5*4 then you get 32 and 20.. im sure you know area but just incase its base times height so 32*20=640

The larger of two numbers is 15 more than 3 times the smaller number. If the sum of the two numbers is 63 find the numbers
scoray [572]

Answer:

X = 51

Y = 12

Step-by-step explanation:

2 numbers: (Larger) Number 1 is x and Number 2 is y

The equation is x + y = 63

  • x = 3y +15
  • y = y

New equation is:

  • 3y + 15 + y = 63

Combine like variables:

  • 4y + 15 = 63

Solve:

  • 4y + 15 - 15 = 63 - 15
  • 4y = 48

Divide 4 from each side:

  • <em><u>y = 12</u></em>

To find x fill in the variables from the 'x =' equation:

  • x = 3y + 15
  • x = 3( 12) + 15
  • <em><u>x = 51</u></em>

Round 715 to the nearest the ten
Mariana [72]
Here's a good rhyming rule to keep in mind.

Zero to four, you get no more.

Five to nine, move up one time.

With this rule you can see that there is a 5 at the end, therefor you should round up. Your number is 720.

How do you solve equations that contain like terms
lina2011 [118]
To solve an equation that contains LIKE TERMS you just have to combine them together.

For example, 3x-22+2x=48.

3x-22+2x=48 Add both x's together.

5x-22=48 <this will be the answer. After that, just solve it like a regular equation.

If the equation that you're trying to solve looks like this, 5x-41=59+9x
Subtract the smallest number on both sides. 

5x-41=59+9x
-5x           -5x
-41=59+4x <this will be your answer and then you just have to solve it like a regular equation

write the equation of the line in slope intercept form with the given conditions (slope = 3 and passes through (1,-3))
cupoosta [38]

Answer:

Because we have a point and slope, we can use at the beginning the point-slope form: y-y1=m(x-x1)

Step-by-step explanation:

m=3 , x1=1 , y=-3

y-(-3)=3(x-1)

y+3=3x-3      subtract 3 from both sides

y=3x-6    the answer in the slope-intercept form y=mx+b
