An algebra class normally has y students, but today it is just 2/3 full. Express the number of students in class today terms of y.
Answer:
2/3y
Step-by-step explanation:
If the class usually has y students and has 2/3 today, it can be represented by 2/3y.
Since multiplying a number or variable by 2/3 makes it 2/3 of the amount, 2/3y will represent the people in the class.
So, in terms of y, 2/3y represents the number of students in class today.

Given Eq:
√x + 3 = x - 3Solving this:
Squaring both sides,
➝ x + 3 = (x - 3)²
➝ x + 3 = x² - 6x + 9
Now shifting RHS to LHS,
➝ x + 3 - x² + 6x - 9 = 0
➝ -x² + 7x - 6 = 0
➝ x² - 7x + 6 = 0
Now finding the values of x by middle term factorisation,
➝ x² - 6x - x + 6 = 0
➝ x(x - 6) - 1(x - 6) = 0
➝ (x - 1)(x - 6) = 0
➝ x = 1 or 6.
But here, you can see, x = 1 is not a solution to the original equation because when we say about square roots, value can't be negative.
Hence,
As a result, the only valid solution to the original equation is x = 6.⛱️ [tex] \large{ \blue{ \bf{FadedElla}}}[/tex]
Aveterinarian uses the function f(t) =3.7t +21 to estimate a puppy's future weight in pounds as a function of time in months
f(t) = 3.7t + 21
where t is the time in months
f = 3.7t /t + 21 / t
f = 3.7 + 21/t
The puppy's future weight in pounds as a function of time in months can be represented by f = 3.7 + 21/t.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
Given that veterinarian uses the function f(t) =3.7t +21
Thus, f(t) = 3.7t + 21 , where t is the time in months
To estimate a puppy's future weight in pounds as a function of time in months, we have to divide by time t.
f = 3.7t /t + 21 / t
f = 3.7 + 21/t
Hence, the puppy's future weight in pounds as a function of time in months can be represented by f = 3.7 + 21/t.

What is m<1
A. 130°
B. 70°
C. 60°
D. 120°
Answer:
120 degrees
Step-by-step explanation:
To find m<1 we must first find the other angles.
First, find m<CDB. To do this use the complementary angle 130. So m<CDB=180-130, which means m<CDB=50.
Then find m<2, to do this remember that all triangles equal 180. So to find m<2 solve the equation m<2=180-(70+50), which equals 60 degrees.
Finally find m<1 the same way you found m<CDB, using the complementary angle 2. m<2=180-60, therefore m<1=120.
Answer:
120

No estudo da circunferência é muito importante diferenciar diâmetro e raio, muito erros são cometidos pela troca desses conceitos e consequentemente a troca de seus valores. A medida do comprimento de uma circunferência é determinada pela fórmula C = 2 π. R , ou seja comprimento da circunferência é igual ao dobro do valor do π multiplicado pelo valor do raio dessa circunferência. Calcule qual a medida em cm de uma circunferência: a) cujo diâmetro mede 10 cm. b) cujo raio mede 12 cm. c) cujo diâmetro mede 2 cm. d) cujo raio mede 5 cm.
Explicação passo a passo:
A circunferência de um círculo é expressa como mostrado;
C = 2πR
R é o raio
Em termos de diâmetro;
C = πD
D é o diâmetro
a) Se o diâmetro for 10cm
Circunferência C = π (10)
C = 10 (3,14)
C = 31,4cm
b) Se o raio for 12cm
C = 2πR
C = 2π (12)
C = 24π
C = 24 (3,14)
C = 74,36cm
c) Se o diâmetro for 2cm
Circunferência C = π (2)
C = 2 (3,14)
C = 6,28cm
d) Se o raio for 5cm
C = 2πR
C = 2π (5)
C = 10π
C = 10 (3,14)
C = 31,4cm

Step-by-step explanation:
Jada plans to serve milk and healthy cookies for a book club meeting
She is preparing 12 ounces of milk and 4 cookies per person
There are 15 people in the club
A package of cookies contains 24 cookies and costs $4.50
A 1-gallon jug of milk contains 128 ounces and costs $3
Let us represents number of people in the club by n
The the ounces of milk = m
The number of cookies = c
Jada's budget in dollars = d
y = 12(15)
She is preparing 4 cookies per person
4n = c
Since A package of cookies contains 24 cookies
She needs = 15 × 4 = 60 cookies
60 ÷ 24 = 2.5
Hence, approximately, she has to buy 3 packages of cookies
She needs = 15 × 12 = 180 ounces of milk
A 1-gallon jug of milk contains 128 ounces
180 ÷ 128 = 1.406
She needs to buy 2 A 1-gallon jug of milk
Note that: from the question
The cost of each jug of milk is $3
The cost of each package of cookies is $4.50
b represents Jada's budget in dollars
b = 2(3) + 3(4.50)

Anya walked 7/10 km to the bank and then walked 3/4 km to the flower shop. What is the total distance Anya walked? Show your work. Write your answer as a mixed number.
Answer:
1 and 9/20
Step-by-step explanation:
add your fractions together 7/10 + 3/4
make them have the same denom 14/20 + 15/20
so its 29/20
to get the mixed fraction, divide 29/20 to get 1.45. The 1 is your whole number. Subtract 20 from 29 to get 9, which is what is remaining, and will go over 20.
the answer is 1 and 9/20
work:
7/10km = 14/20km
3/4km = 15/20km
15/20+14/20=29/20km
29/20 as a mixed number is 1 and 9/20.

3 x tiles and 8 positive 1 tiles = 4 x tiles and 6 positive 1 tiles
x = negative 14
x = negative 2
x = 2
x = 14.
Answer:
Therefore, the correct option is;
x = 2
Step-by-step explanation:
Let x represent the number of tiles, and let 1 represent the positive 1 tiles
Let the and operator represent addition we have;
3 × x + 8 × 1 = 4 × x + 6 × 1
We simplify as follows;
3·x + 8 = 4·x + 6
We move and place like terms together as follows;
4·x - 3·x = 8 - 6
From which we have;
x = 2
Therefore, the correct option is x = 2

Isaac is purchasing two pairs of shoes—one pair for $37.00 and the second pair for $42.00. The state sales tax applied to Isaac’s bill is 7%. How much is Isaac’s total bill? Show your work.
Answer:
a) 37 + 42 =79
=7/100 x 79
=553/100
=5.53
Isaac's total bill = 79 + 5.53 = $84.53
b) 25/100 x 79
= 19.75
= 79 - 19.75
= $59.25 (before tax)
7/100 x 59.25
= 414.75/100
= 4.15
= 59.25 + 4.15
= $63.4 (after adding tax)
Step-by-step explanation:First we have to take out the percentage of discount and minus it from the total cost . To find the discounted price with tax, we have to take out the percentage of the tax from the discounted amount and add it to the discounted amount to get the total cost.
Answer:
Isaac paid $84.53
Step-by-step explanation:
37+42=79.00
79.00* .07=5.53
5.53+79.00=84.53
