Answer:
x = -5.33333333
Step-by-step explanation:
Using dist. prop
3x - 6 + 4x = 10x + 10
combine like terms
7x - 6 = 10x + 10
move the 6 over
7x = 10x + 16
move the 10x over
-3x = 16
divide by -3
x = -5.33333333
Answer:
see explanation
Step-by-step explanation:
Slope- intercept form is y = mx + c
Rearrange the given inequalities into this form
x + y ≤ 55 ( subtract x from both sides )
y ≤ - x + 55
-------------------------------------------------
60x + 40y > 600 ( subtract 60x from both sides )
40y > - 60x + 600 ( divide all terms by 40 )
y > - x + 15
I'm going to assume that you meant 450kg for the combined weight, 190kg more and 3 Llamas. I'm pretty sure Llamas and Okapis don't weigh 450450450kg (that's 993,073,252 pounds). :)
x= Okapi weight
y= Llama weight
EQUATIONS:
There are 2 equations to be written:
1) 450kg is equal to the weight of one Okapi and one Llama
450kg= x + y
2) The weight of 3 llamas is equal to the weight of one Okapi plus 190kg.
3y=190kg + x
STEP 1:
Solve for one variable in one equation and substitute the answer in the other equation.
450kg= x + y
Subtract y from both sides
450-y =x
STEP 2:
Substitute (450-y) in second equation in place of x to solve for y.
3y=190kg + x
3y=190 + (450-y)
3y=640 -y
add y to both sides
4y=640
divide both sides by 4
y=160kg Llama weight
STEP 3:
Substitute 160kg in either equation to solve for x.
3y=190kg + x
3(160)=190 + x
480=190 + x
Subtract both sides by 190
290= x
x= 290kg Okapi weight
CHECK:
3y=190kg + x
3(160)=190 + 290
480=480
Hope this helps! :)

Probably shouldn't put this as a math question
