Answer:

The answer to your question is the big dog weighs 120 pounds

Step-by-step explanation:

Data

big dog = b    

medium dog = m

small dog = s

Equations

       b = 5s

       m = 12 + s

       s = 2/3 m

Process

1.- Substitute m in the last equation

       s = 2/3(12 + s)

       s = 24/3 + 2/3s

       s - 2/3s = 8

       1/3 s = 8

             s = 8(3)

             s = 24 pounds

2.- Substitute s in the first equation

        b = 5(24)

        b = 120 pounds

The sum of the angle measures of a quadrilateral is 360°. Write and solve an equation to find the value of x.
Leokris [45]

Given: The shape is a quadrilateral, which means four angles with a sum of 360°. The known measures are 112 and 73, and there are two unknown measures. They are probably identical, considering the fact that they both have the variable x.

Numerically, this would be 112 + 73 + x + x = 360.

Simplify.

(112 + 73) + (x + x) = 360

--> 185 + 2x = 360

Isolate the variable by subtracting 185 from both sides.

2x = 360 - 185

--> 2x = 175

If 175 is twice as much as x, then x = \frac{175}{2}

x = 87.5

Plug in the value of x:

112 + 73 + 2(87.5) = 360

--> 185 + 175 = 360

X has an angle measure of 87.5°

The difference between a number x and 3 is no more than 2
Vlad [161]

Answer:

  • x -3 ≤ 2
  • x ≤ 5

Step-by-step explanation:

"The difference between A and B" means "A - B". "Is no more than" means "is less than or equal to." Applying these translations to your statement gives ...

  x - 3 ≤ 2

Adding 3 to both sides of this inequality tells you its solution:

  x ≤ 5

Can someone please answer this for me
kifflom [539]

Answer:

x = 7.5

y = 75

Step-by-step explanation:

if one angle of an equilateral triangle is 60 degrees (180/3) then 4x + 2x + 2x = 8x = 60, so x = 7.5

for y, we'll have to take the right triangle. we know that 2x = 15, and MON = 60, so 180 - 60 - 15 = 105.

180 - 105 will give us y, which is 75
