Answer:
14.8
Step-by-step explanation:
The Pythagorean theorem applies.
... x² = 7² + 13² . . . . . the square of the hypotenuse is the sum of the squares of the legs
... x² = 218
... x = √218 ≈ 14.8
Answer:
12.50x+30
Step-by-step explanation:
Answer:
The solution is x = -2, y = -3
Step-by-step explanation:
Let's start with the equation 3x + y = -9
Substitute the y for 5x+7 seen in the second equation
Now you have 3x + (5x+7) = -9
Lets solve:
Let's add the x's
Now we have 8x + 7 = -9
Substracy seven from each side
Now we have 8x = -16
Now let's divide 8 on each side
Now we have x = -2
Now lets plug in -2 to the second equation
The second equation is y = 5x+7
When we plug in -2 we get y=5(-2)+7
We multiply
We now have y = -10+7
Add
y = -3
The solution is x = -2, y = -3
Answer:
7 x 75 then 13.25 - 5.25
Step-by-step explanation:
do the math then thats the awnser
Answer:
x=2.142137
Step-by-step explanation:
Solve Exponent.
12x=205
log(12x)=log(205)(Take log of both sides)
x*(log(12))=log(205)
x=
log(205)
log(12)
x=2.142137
