I love these problems, because it's just about reading the question. All you need to do is break it down. What do we know the "sum of" something is? We know that it means addition. What are we adding? "three times a number b and 33". Well, how can we express "three times b"? 3b! Right! Well, we know we're adding that to 33, so you're almost done. Right now you should have 3b+33. And what <em>is</em> 3b+33? at least 33. How can we express "at least"? >=, greater than or equal to, right! Finally, we have our answer. 3b+33>=35.

75 - 3.5x - 4x = 4x + 6
stepladder [879]

Answer:

x = 6

Step-by-step explanation:

Step 1: Write equation

75 - 3.5x - 4x = 4x + 6

Step 2: Solve for <em>x</em>

  1. Combine like terms: 75 - 7.5x = 4x + 6
  2. Add 7.5x on both sides: 75 = 11.5x + 6
  3. Subtract 6 on both sides: 69 = 11.5x
  4. Divide both sides by 11.5: 6 = x
  5. Rewrite x = 6

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

75 - 3.5(6) - 4(6) = 4(6) + 6

75 - 21 - 24 = 24 + 6

54 - 24 = 30

30 = 30

PLZ HELP!!!! A pair of equations is shown below: y = 6x − 4 y = 5x − 3 Part A: In your own words, explain how you can solve the
Goryan [66]

Answer:

Step-by-step explanation:

y = 6x − 4

y = 5x − 3

A: chose a value for x(input) and get the out put (y) because the equation already in the slope intercept mode:y=mx+b

x                   y=6x-4                  y=5x-3

1                    y=2                        y=2

2                    y=8                        y=7

0                     -4                            -3

slope  :

y=6x-4    slope is 6            y intercept(0,-4)

y=5x-3      slope is 5          y intercept (0,-3)

solution of the pair of equation is  the point of intersection :

6x-4=5x-3

6x-5x=-3+4

x=1   and y=6x-4   ⇒ y=6-4=2

X = 5
Y = 6
Simply we just compare the two shapes and we can see that 6 decreases to 4..so we would assume the rest would decrease by 2. If we were not so sure we could simply do a^2 + b^2 = c^2 and fill in the numbers
