First off, notice that this is a right triangle.
You can use this to help write equation.
Equation : x+ (4x-85)=90. The correct answer is "c"
Step-by-step explanation:
If u want to get the product of a number and two ..
Then just double the number..
or u can add it to itself again...
For example=1000x2
=2000
or u can
1000+1000
=2000
u should pick the first way as it's faster and efficient
Hope that helps
Answer:
B. Function 2
Step-by-step explanation:
Line P gradient is
Gradient = rise/run
= 1/4
Negative slope so gradient is - 1/4
Out of all the gradient, the lowest value has to be function 2 or line p & not 1/4r-5 because when r is 1 we get a gradient of 1.
-1/4xr - 5
-1/4x1 - 5
-1/4-5
-1/-1 = 1
Plus, 1 is greater than - 1/4 or - 0.25.
She is a quarter of the mountain, which is 125 meters. 125 x 4 is 500. the ledge is 425 feet down the mountain. 500 - 425 is 75. When she reaches the ledge, she will be 75 meters above ground.
Answer:
x=1 1/18
Step-by-step explanation:
7(x+8)+4=-11(x-8)-9
distribute- 7x+56+4=-11x-88-9
7x+60=-11x+79
subtract 60 from both sides (60),(79)
7x=-11x+19
add 11x on both sides
18x/18 and 19/18
which gives you x=1 1/18 or 19/18
