Answer:
600
Step-by-step explanation:
mutiply all 6x4x5x5
1st do 5x5=25 no you have 6x4x25
2nd do 6x4= 24 now you have 24x25
and that equal 600!
Hope this help you
enjoy your day
Answer:
3x + 7y = 21
Step-by-step explanation:
We have value of two points (0,3) and (7,0)
First, let's find the slope of this line. The formula for slope is:
Change in y/Change in x or (y₂ - y₁)/(x₂-x₁)
Where x₁ = 0 x₂= 7 y₁ = 3 y₂ = 0
(y₂ - y₁)/(x₂-x₁)
= (0-3)/(7-0)
=-3/7
Now we can write the equation in point-slope form:
y-y₁ = m(x-x₁)
y - 3 = -3/7(x-0)
y-3=-3x/7
y=-3x/7 + 3
Now let's convert this to standard form, by making the y-intercept by itself:
Ax + By = C
y=-3x/7 + 3
Multiply through by 7
7(y) = 7(-3x/7) + 7(3)
7y = -3x + 21
3x + 7y = 21
Remark
Set up the equation from the word problem.
Equation
7*x - x = -48 Combine like terms
6x = - 48 Divide by 6
x = - 48 / 6
x = - 8 <<<<< Answer
