Answer:
x=4 and y=2
Step-by-step explanation:
2x=3(-x+6) +2
2x= -3x+18 +2
2x= -3x+20
5x=20
x=4
y=-(4) +6
y=2
Un elev a depus la banca suma de 250 lei. Știind ca banca oferă dobânda anuala de 1%,iar stația impozitează dobânda cu 16%,aflati ce suma va avea elevul după un an de depunere.
Răspuns:
292,50
Explicație pas cu pas:
Dobânda totală% = (1% + 16%) = 17% = 17/100 = 0,17
Suma principală depusă, P = 250
Suma totală, A după 1 an poate fi calculată astfel:
A = P (1 + rt)
Unde ; r = rata dobânzii; t = timp
A = 250 (1 + (0,17 * 1))
A = 250 (1,17)
A = 292,5

The probability that Jamil will be late for work is 0.2.
Work out the probability that Jamil will not be late for work.
Given:
The probability that Jamil will be late for work is 0.2.
To find:
The probability that Jamil will not be late for work.
Solution:
We have,
P(Jamil will be late) = 0.2
We know that,
P(Jamil will not be late) = 1 - P(Jamil will be late)
= 1 - 0.2
= 0.8
Therefore, the probability that Jamil will not be late for work is 0.8.

Step-by-step explanation:
Answer:
The paper is right.
Step-by-step explanation:
The fraction is [tex]\frac{4}{5}[/tex] multiplied by [tex]\frac{3}{3}[/tex] and the answer is [tex]\frac{12}{15}[/tex]. How did it do that? Well, the numerator (top number),4, was multiplied by the other numerator ,3, which is 12. The same thing with the denominator (bottom number), the denominator,5, was multiplied by the other denominator ,3, which is 15. But as seen in the paper, the fraction
what percent of 66 is 13 help please
Answer:
200
Step-by-step explanation:
so the expression is what is 66 is 13% of what number ( i think)
first turn the percent into a decimal by divided it by 100
33/100 = 0.33
because we are trying to find the whole we divide the given part by the decimal so,
66/0.33 =200, so
66 is 13% of 200
A discount store bought two dozen cameras for $14 each.
After the cameras didn't sell for a long period, the store
decreased their selling price to $10.99 per camera. What was the
store's overall loss on the two dozen cameras?
Answer:
72.24
Step-by-step explanation:
Price for each camera = 14
Number of camera = 2dozen = 12 x 2 = 24
Total cp = 24 x 14 = 336
~~~~~~~~~~~~~~
Price for each camera= 10.99
Number of cams = 24
Total sp = 10.99 x 24 = 263.76
Loss = 336 - 263.76 = 72.24
F(x)=3x+2, if you are asked to find f(4), what does this mean?
Answer:
you substitute x for 4
Step-by-step explanation:
so its f(x) and f(4) so you use 4 for x so you would solve f(x)=3(4)+2

Pleaseee answer correctly !!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!!!!!!
Answer:
Now how did I find the translation rule ( x - 1, y + 4). Well basically, I did was
8 - 9 = -1
-4 - (-8) = 4
Now if you use the same translation rule for (9, -8), you will get :-
(x - 1, y + 4)
( 9 - 1, -8 + 4)
( 8, -4)
I get the same answer that is given in the problem.
Hope this helps, thank you !!

Can someone please help.!
Answer:
C
Step-by-step explanation:
this is because this is the only value that will yield 40 when you have 0 as a x value
40(1/4) to the 0
which is 40*1=40
if my answer helps please mark as brainliest.
Answer:
C. 40(0.25)^x
Step-by-step explanation:
Given that it is an inverse function we can see that when x = 0, y = 40 and when x = 1, y = 10. Then you look for which function fits the criteria, given that only 40(0.25)^x does it is C.

5x4y3 * 3x3y8 need help
Answer:
15x^7y^11
Step-by-step explanation:
First, multiply the coefficients 5 and 3 together. We get:
15x^4y^3 * x^3y^8
Please note that it's mandatory to use " ^ " to indicate exponentiation.
Since x^4*x^3 = x^7, we next obtain:
15x^7y^11

Step-by-step explanation:
Answer:
Step-by-step explanation:
first find angle ∠U,
As sum of angle in triangle = 180°
Now ∠U+∠V+∠W=180°
88°+38°+∠U=180°
∠U=54°
Now total horizontal line = 180°
∠NUV=180°-54°=126°

Work at a convenience store 60% of your time, and earn $11.00 an hour. Referee games at your city park 25% of your time, and earn $19.00 an hour. Do your elderly neighbor’s housework 15% of your time, and earn $16.00 an hour. What will your average hourly wage be? Enter your answer up to two decimal places.
Answer:
13.75
Step-by-step explanation:
The expected value of the hourly wage is the sum of the probabilities (percentage of time spent on each job) multiplied by the payoff (money earned) from each possible occurrence (job):
(0.6 × 11) + (0.25 × 19) + (0.15 × 16) = $13.75.

Answer:
1. 2x +2y = 310; x -y = 55
2. y = 50, x = 105
Step-by-step explanation:
Let the numbers be represented by x and y. Double the numbers would give 2x and 2y. We're told the sum of the doubled numbers is 310, so one equation is ...
2x + 2y = 310
The difference of the numbers is (x-y). We're told that difference is 55, so the other equation is ...
x - y = 55
__
We can divide the first equation by 2, and subtract the second.
1/2(2x +2y) -(x -y) = 1/2(310) -(55)
2y = 100 . . . . . . . simplify
y = 50 . . . . . . . . . divide by 2
x -50 = 55 ⇒ x = 105 . . . . use the second equation to find x
The two numbers are 105 and 55.
