Answer:
5 1/10 ÷ .15 is 34 so she will be able to perform 34 experiments
The straight line ON has the following equation :
(x - 18)/(x - 0) = (y - 12)/(y - 0)
Where (18,12) are coordinates of N and (0,0) are coordinates of O.
x - 18/x = y - 12/y
-18y = - 12x
y =12x/18 - - - - - (a)
The coordinates satisfy equation (a) are (7.5, 5)
Therefore D is the correct answer.
Good luck
Answer:
$8
Step-by-step explanation:
We can write an equation with the scenario given and solve for what we need, Alberto's weekly allowance.
Let his weekly allowance be "x"
Since he spend HALF of it, he spent 0.5x of it.
He has remaining also 0.5x of it
Now, whatever he has (0.5x), he gets $4 more from cleaning windows. After that he has:
0.5x + 4
This amount is equal to $8, so we can write:
0.5x + 4 = 8
0.5x = 8 - 4
0.5x = 4
x = 8
So, alberto's weekly allowance is $8
Answer:
a=65
Step-by-step explanation:
Avem 375 pagini
Notam cu a numaruide pagini
In prima zi avem-a, poi a doua zi-a+5, a treia-a+10, apatra-a+
15 si a cincea zi avem-a+20
Le adunam si egalam cu 375
5a=50=375
5a=325
a=65
Answer:
D 144 in hope this helps you on your test
