Answer:
The answer is y = -15x + 35.
Step-by-step explanation:
We want to isolate y, so we cancel everything on that side of the equals except y. We begin with the term farthest away from y, which would be 3x. Since it is positive, to cancel it we will subtract. This will give us 1/5y = 7-3x.
Next we want to cancel the 1/5. Since it is directly beside y, this means it has been multiplied; to cancel, we will divide. Divide both sides by 1/5, and we have y = (7-3x)÷(1/5). When we divide fractions, we flip the second one and multiply; this means we have y=(7-3x)*5.
Using the distributive property, we have y=7*5-3x*5, which gives us y=35-15x. We can write this as y=-15x+35.
Answer:
y = 35 - 15x
Step-by-step explanation:
Given
3x + [tex]\frac{1}{5}[/tex] y = 7 ( subtract 3x from both sides )
[tex]\frac{1}{5}[/tex] y = 7 - 3x ( multiply both sides by 5 to clear the fraction )
y = 5(7 - 3x) , that is
y = 35 - 15x

What made the two equivalent fractions 1/2 and 5/10 have the same value
Answer:
1/2 and 5/10 are equivalent because when you reduce 5/10, you get 1/2. Also, whenever we speak, we always say half of 10 is 5. Finally, the factor of 5 made them have an equal value. Therefore, 5/10 and 1/2 are equivalent.
Hope this helps!
Multiply the fraction by 5/5 makes them equivalent fraction.
what is fraction?The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.Given:
1/2 and 5/10
Now, to make fraction equivalent we have to find the factorizing factor.
As, 1/2 x 5/5= 5/10
Hence, multiply the fraction by 5/5 makes them equivalent fraction.

Round 97.081 to the nearest tenth
Answer:
97, that's the answer.
Answer: 97.1
Step-by-step explanation: the tenth is the first number after the decimal place so in your question that number is the 0 and the number next to it is 8 so, our 0 needs to change because 8 is bigger than 5 on the number line which makes our 0 increase to 1. You don't need to change the whole number at all.

Answer:
m = - 27
Step-by-step explanation:
Given
3(m - 5) + 11 = - 85 ← distribute and simplify left side
3m - 15 + 11 = - 85
3m - 4 = - 85 ( add 4 to both sides )
3m = - 81 ( divide both sides by 3 )
m = - 27
if
f(x)=x^2+2x-4
and
g(x)=3x+1
find
f(g(x))=__x^2+__x+__
Step-by-step explanation:
f(x) = x² + 2x - 4
g(x) = 3x + 1
f(g(x)) = f(3x + 1)
f(3x + 1) = [3x + 1]² + 2[3x + 1] - 4
= 9x² + 6x + 1 + 6x + 2 - 4
= 9x² + 12x -1
PLS HELP, I'LL GIVE YOU NITRO ON DISC0RD!!! Jose ran a concession stand last Saturday and made $79.80 from selling a total of 42 hot dogs and hamburgers. Each hot dog sold for $1.50 and each hamburger sold for $2.70. Which system of equations can be used to determine the number of hot dogs, x, and hamburgers, y, that were sold?
Answer:
1.50x + 2.70y - 84 = 79.80
Explanation: I REALLY don't know if this is right, but I hope I helped you out at least a little bit.
Answer:
x + y = 42
1.50x + 2.50y = $79.80
x = 28 hot dogs
y = 14 hamburgers
Step-by-step explanation:
x = hot dogs
y = hamburgers
Equation:
x + y = 42
1.50x + 2.50y = $79.80
I used Substitution
x = 42 - y
1.50(42 - y) + 2.50y = 79.80
63 - 1.50y + 2.70y = 79.80
63 + 1.2y = 79.80
Substract 63 from both sides
1.2y = 16.8
Divide 1.2 on both sides
y = 14
x + y = 42
x + 14 = 42
x = 28
y = 14

In 5.......4........3.......2......1...... ANSWER
Answer:
It's C
Step-by-step explanation:
The mean number of days employee were sick is 4.43 days.
Option C is correct.
Here,
Given that;
The department manager recorded the number of sick days taken last year by each employee, as shown in the table.
We have to find the mean number of days employee were sick.
What is Mean?
The average of the given numbers is called Mean and is calculated by dividing the sum of given numbers by the total number of numbers.
Now,
In given table;
Number of sick days are,
7, 4, 2, 6, 4, 5, 3
Hence,
Mean number of days employee were sick = [tex]\frac{7+4+2+6+4+5+3}{7}[/tex] [tex]= \frac{31}{7}[/tex][tex]= 4.4285[/tex]
Now, Rounding the number to the nearest hundredth we get;
Mean of number of days employee were sick = 4.43 days
Hence, The mean number of days employee were sick is 4.43 days.
Option C is correct.

I WILL GIVE BRAINLIEST!!!!! Consider the scenario below. This morning Haidar noticed that her dog, Aldi, seemed unwell. She took him to the vet, where he was diagnosed with an ear infection. The veterinarian prescribed an antibiotic called amoxicillin to help Aldi feel better. Haidar will give Aldi 150 mg of the antibiotic once each day for 10 days. Each time Haidar gives Aldi his next dose of medication, 40% of the previous dose remains in his bloodstream. Use what you know about recursive sequences and iteration to explore the mathematics related to this scenario. 1. Determine the amount of medication that is in Aldi’s bloodstream after Haidar gives him each of the 1st, 2nd, 3rd, and 4th doses of amoxicillin. Show your work.
Answer:
225 mg remain in Aldi bloodstream
Step-by-step explanation:
150mg of amoxicillin was given daily for 10 days equals 1,500
of the 1500-40% =600mg
600mg divided by 4 days = 225mg still in blood stream
