It would be helpful to draw out a diagram but I'll explain in words.

We start at 0, ground level.

Then up a 100 metre hill, so now we are at 100m.

It plunges down 72, so we take away 72 to get 28m.

Then it takes them back up 48m, so we add 48 to get 76m.

That means that they are 76m above from where they started, ground level.

Hope I helped!

saw5 [17]

Answer:

Given the statement:

9 less than the sum of x and 5

"Sum of x and 5" means x+5

"\text{less than}" means subtract

then;

the statement 9 less than the sum of x and 5 becomes;

⇒(x+5) - 9

⇒x+5-9 = x-4

Therefore, the expression for the given statement is (x+5) - 9

Graph the direct variation y=−1.5x. Using the graph, find:
Mariana [72]
Y=-3

-3=-1.5x
you substitiue y value, then you divide both sides by -1.5 and you get 2 for x.
(2,-3)

y=4.5
4.5=-1.5x
you substitute y value, then again you divide both sides by -1.5 and you get 3.
(3,4.5)



y=6
6=-1.5x
same thing for this last one. then once again divide by -1.5 and you get -4.
(-4,6)

In a​ film, a character is criticized for marrying a woman when he is three times her age. He wittily​ replies, "Ah, but in 25ye
Sonbull [250]

Answer:age of the man: 75 age of the woman:25

Step-by-step explanation:

First, We need to define the variables

x: age of the man

y: age of the woman

at the first time he has three times her age

x=3y                (1)

in 25 years time

(x+25)=2(y+25)                 (2)

we clear the equation

X+25=2y+50

X=2y+25

we substitute in the (1) equation:

2y+25=3y

y=25

x=3*25=75
