ithout graphing, determine the number of solutions to the system of equations.
2x−10y=−2
y=x/5−1
Select the correct answer below:
no solution
one solution
infinitely many solutions
Answer:
No solution
Step-by-step explanation:
(I am going to use substitution)
2x−10y=−2
y=x/5−1
(Substitute the y into the other problem)
2x - 10 (x/5 -1) = -2
2x - 2x + 10 = -2
10 = -2
No solution

A drug prescription of 45 pills costs $427. 95. If each pill contains 3 mg of medication, what is the cost per milligrams?
Total milligrams
45(3)135mgCOST PER MG:-
TOTAL COST/total Mg427.95/1353.17$/pillsAnswer:
$3.17
Step-by-step explanation:
1 pill = 3 mg
⇒ 45 pills = 45 × 3 = 135 mg
45 pills = $427.95
⇒ 135 mg = $427.95
⇒ 1 mg = $427.95 ÷ 135 = $3.17

compute the probability of tossing a six-sided die and getting a number less than 3
Answer:
We can think of our denominator as 6 in our probability, because there are 6 total sides to this die.
Out of those 6 sides, they want to find out if we can roll a number less than 3.
First, let's find how many numbers there are on this die that are less than 3.
1 and 2, so there are 2 sides that contain numbers less than 3 on this die.
So there is a 2 out of 6 chance(2/6) which can be simplified to 1/3, of selecting a number less than 3 when rolling a die.
1/3 probability.
Convert this into a percent if you'd want:-
1/3 · 100
= 33.333... which can be rounded to a 33% probability.

I WILL GIVE YOU 30 IF YOU JUST HELP ME PLEASE?
Answer:
In 4 years you will get 44 and in 4 years and 6 months you will get 49.5
Step-by-step explanation:
550*0.02= 11 (yearly interest)
11*4 years= 44
11/12months=0.917
0.917*6 months= 5.5
44+5.5=49.5 (4 years and 6 months interest)

For which values of x is the expression undefined x-8/x-5
Answer:
x = 5
Step-by-step explanation:
Any number over 0 is undefined. Given that, the values of x that make this expression undefined make the denominator equal to 0
x - 5 = 0
x = 5

Two number cubes whose sides are numbered 1 through 6 are rolled on a table. The two numbers showing are added. If you repeat this process 300 times, how many times would you expect the two cubes to add to exactly 7? ASAP
Answer:
50 times.
Step-by-step explanation:
When the 2 number cubes are rolled once:
The possible outcomes for a total of 7 are:
1 and 6
6 and 1
2 and 5
5 and 2
3 and 4
4 and 3
= 6 outcomes.
The total of all possible outcomes = 6 * 6 = 36.
So Prob( total of 7 in one throw of teh 2 cubes) = 6/36 = 1/6.
For 300 throws you would expect the total of 7 to occur
1/6 * 300 = 50.
Answer:
Step-by-step explanation:

At a concession stand, seven hot dog(s) and four hamburger(s) cost $21:25, four hot dog(s) and seven hamburger(s) cost $22.75 Find the cost of one hot dog and the cost of one hamburger
Step-by-step explanation:
If 4 hamburger = $21.25
1 hamburger = x
Cross multiply
4 x x = $21.25 x 1
4x = $21.25
Devide both side with the coefficient of x
4x/4 = $21.25/4
X = $5.3125
Therefore 1 hamburger cost $5.31
If 4 hotdogs = $22.75
1 hotdog = y
Cross multiply
4 x y = $22.75 x 1
4y = $22.75
Devide both sides with the coefficient of y
4y/4 = $22.75/4
Y = $5.6875
Therefore one hotdog cost $5.69
Answer:
See below ↓↓↓
Step-by-step explanation:
Given :
7 hot dogs + 4 hamburgers = $21.504 hot dogs + 7 hamburgers = $22.75Let's set some variables.
hot dogs = xhamburgers = ySo, our equations are :
7x + 4y = 21.504x + 7y = 22.75Mulitply equation #1 by 7 and equation #2 by 4.
49x + 28y = 150.50 (Equation 3)16x + 28y = 91.00 (Equation 4)Subtract equation 4 from equation 3.
49x - 16x + 28y - 28y = 150.5 - 9125x = 59.5x = $2.38 [cost of one hot dog]Substitute value of x in equation 4.
16(2.38) + 28y = 9138.08 + 28y = 9128y = 52.92y = $1.89 [cost of one hamburger]Help me please :(( ......

Solve the system of equations.
5x−4y=−10
y=2x−5
Answer:
x = 10
y = 15
Step-by-step explanation:
5x − 4y = −10 ⇒ ( 1 )
y = 2x − 5 ⇒ ( 2 )
Let us find the value of x.
For that, we can replace y with ( 2x - 5 ).
Let us take equation 1.
5x − 4y = −10
5x - 4 ( 2x − 5 ) = -10
5x - 8x + 20 = -10
-3x = -20 - 10
-3x = - 30
Divide both sides by ( -3 ).
x = 10
And now let us find the value of y.
Let us take equation 2.
y = 2x − 5
y = 2 × 10 - 5
y = 20 - 5
y = 15
Answer:
X=10
Step-by-step explanation:
5x-4y=-10.....1
y=2x-5......2
sub 2 into 1
5x-4(2x-5)=-10
5x-8x+20=-10
5x-8x=-10-20
-3x=-30
x=10
sub x=10 into 2
y=2(10)-5
y=20-5
y=15

Samir also picks pumpkins from his garden. He picked 6 7/10 kg, but 2.6 of pumpkins were spoiled and could not be used for decoration. How many kilograms of pumpkins were not spoiled? Write an equation that shows how you reached your answer.
Answer:
6.7kg - 2.6kg = 4.1kg
Step-by-step explanation:
6 7/10 is equal to 6.7. If we have 6.7kg of pumpkins, but we can't use 2.6kg, then we subtract to find the amount that we can use.

Answer:
A = 44.42°
Step-by-step explanation:
SohCohToa
Soh = sin(theta)= opp/hyp
Coh = cos(theta)= adj/hyp
Toa = tan(theta)= opp/adj
Coh = cos(theta)= adj/hyp
cos(A)= adj/hyp
cos(A)= 5/7
A = cos^-1(5/7)
A ≈ 44.4153086
