Answer: y = 10
Step-by-step explanation: Hi there!
To get started, first, we have to subtract 2y from 9y on the left side.
7y + 8 = 4y + 38
Then subtract 4y on both sides.
3y + 8 = 38
Then subtract 8 on both sides
3y = 30
Finally divide by 3 on both sides.
y = 10
The answer is y = 10.
Answer: y=10
Step-by-step explanation:
9y-2y+8=4y+38
[tex]\mathrm{Add\:similar\:elements:}\:9y-2y=7y[/tex]
7y+8=4y+38
[tex]\mathrm{Subtract\:}8\mathrm{\:from\:both\:sides}[/tex]
7y+8-8=4y+38-8
[tex]\mathrm{Simplify}[/tex]
7y=4y+30
[tex]\mathrm{Subtract\:}4y\mathrm{\:from\:both\:sides}[/tex]
7y-4y=4y+30-4y
[tex]\mathrm{Simplify}[/tex]
3y=30
[tex]\mathrm{Divide\:both\:sides\:by\:}3[/tex]
[tex]\frac{3y}{3}=\frac{30}{3}[/tex]
Simplify

2y-8×9 = -3×9×5y+476
Hey there!
Let's solve your equation step-by-step.
[tex]\fbox{2y−(8)(9)=(((−3)(9))(5))(y)+476}[/tex]
Step 1: Simplify both sides of the equation.
[tex]\fbox{2y−(8)(9)=(((−3)(9))(5))(y)+476}[/tex]
[tex]\fbox{2y+−72=−135y+476}[/tex]
[tex]\fbox{2y−72=−135y+476}[/tex]
Step 2: Add 135y to both sides.
[tex]\fbox{2y−72+135y=−135y+476+135y}[/tex]
[tex]\fbox{137y−72=476}[/tex]
Step 3: Add 72 to both sides.
[tex]\fbox{137y−72+72=476+72}[/tex]
[tex]\fbox{137y=548}[/tex]
Step 4: Divide both sides by 137.
[tex]\fbox{137y/137 = 548/137}[/tex]
[tex]\fbox{y=4}[/tex]
Answer:
[tex]\fbox{y=\fbox{4}}[/tex]

Sanjay has 35 pens and Mohan has 40 pens. These two, along with four other friends, collect their pens together. If Sanjay takes back his pens, the average number of pens with the rest of them is 20. What will be the average number of pens with the rest of them, if Mohan also takes back his pens?
"First, you have 35 total pens in the box. 15 are green. to find how many red pens you need to find the difference between 35 and 15 to get how many red pens there are. (35-15= 20) Therefore, there are 20 red pens. The ratio needs to be green pens to red pens. So, there is 15 green and 20 red ( 15/20 or 15:20) Simplify that by 5 and you get 3/4 or 3:4. "
La relación entre la temperatura del aire T (en º F) y la altitud h (en metros sobre el nivel del mar) es lineal para los primeros 20.000m. Si la temperatura a nivel del mar es de 60º F y por cada 5.000 m de altitud que se sube, la temperatura del aire baja 18º F. La temperatura del aire a una altitud de 15000 m es
Answer:
La temperatura del aire a una altitud de 15000 metros sobre el nivel del mar es -66 ºF.
Step-by-step explanation:
Dada la relación de linealidad, construimos una función lineal de la temperatura del aire en función de la altitud con respecto al nivel del mar, la cual es:
[tex]T(h) = T_{L} + \frac{T_{H}-T_{L}}{h_{H}-h_{L}} \cdot h[/tex], [tex]0\,m \leq h \leq 20000\,m[/tex] (Eq. 1)
Donde:
[tex]T_{L}[/tex] - Temperatura del aire a nivel del mar, medida en grados Fahrenheit.
[tex]T_{H}[/tex] - Temperatura del aire a determinada altitud, medida en grados Fahrenheit.
[tex]h_{L}[/tex] - Altura del nivel del mar, medida en metros.
[tex]h_{H}[/tex] - Altura determinada, medida en metros.
[tex]h[/tex] - Altitud con respecto al nivel del mar, medida en metros.
[tex]T(h)[/tex] - Temperatura del aire a una altitud con respecto al nivel del mar, medida en grados Fahrenheit.
Si sabemos que [tex]T_{L} = 60\,^{\circ}F[/tex], [tex]T_{H} = 18\,^{\circ}F[/tex], [tex]h_{L} = 0\,m[/tex], [tex]h_{H} = 5000\,m[/tex] y [tex]h = 15000\,m[/tex], la temperatura del aire a esa altitud es:
[tex]T(15000\,m) = 60\,^{\circ}F + \frac{18\,^{\circ}F-60\,^{\circ}F}{5000\,m-0\,m} \times 15000\,m[/tex]
[tex]T(15000\,m) = -66\,^{\circ}F[/tex]
La temperatura del aire a una altitud de 15000 metros sobre el nivel del mar es -66 ºF.
Laurie saw some stray cats in her backyard. She put out some water and a bowl with 3 cups of food. The cats drank all the water and ate half of the food. How many ounces of food did the cats eat?
Answer:
12
Step-by-step explanation:
1 cup = 8 ounces.
In total, there are 3 cups of food.
So, we do 3 × 8 which would equal 24.
24 ÷ 2 = 12.
12 is half of all the food Laurie gave to the stray cats
Therefore, 12 is the correct answer.

if m∠TUV=(9x+11)°, m∠TUW=(7x-9)°, and m∠WUV=(5x-11)°, find the value of x.
Answer: X = 9
Step-by-step explanation:
We know that a triangle has 3 angles that add up to 180 degrees.
9x+ 11 + 7x - 9 + 5x - 11 = 180
21x - 9 = 180
21x = 189
x = 9
What value of x is in the solution set of 8x 6 12+2x
O-1
O 0
O 3
O 5
Step-by-step explanation:
Just consider the inequalities an equal sign and do the usual way of solving:
8x - 6 > 12 + 2x
8x - 2x > 12 +6
6x > 18
x > 3
*The only rule that you need to remember is that when you multiply or divide a negative number on both sides, then the inequality sign would be reverse.*
Example:
-x + 3 > -2
-x > -2-3
-x > -5
Multiplying both sides by -1:
x < 5

Can you have a triangle with two right angles?
Answer:
no
Step-by-step explanation:
because there are two angles
My Answer ↓
No. You cannot have a triangle with two right angles due to the concept that a triangle can only have 3 sides. Therefore, a triangle can only have 1 right angle.

The perimeter is 60 cm long how long is one side of the square
Answer:
15cm
Step-by-step explanation:
All you need to do for this is divide the perimeter (60) by the number of sides on a square (4). 60÷4=15
Answer:
[tex]15[/tex]
Step-by-step explanation:
Square perimeter is
[tex]P=4s[/tex]
Solving for [tex]s[/tex] we get
[tex]s=\frac{P}{4}[/tex]
So we have
[tex]s=\frac{60}{4}[/tex]
[tex]s=15[/tex].
An article is marked to sell at Rs.1300;if 10% discount is allowed,find the discount amount and selling price.
Answer:
discount amount=Rs. 130
selling price=Rs. 1170
Step-by-step explanation:
discount amount=10%of Rs.1300
=10/100*1300
=1300/10
=Rs. 130
selling price=MRP-discount amount
=1300-130
=Rs. 1170

HOPE IT HELPS YOU :)
Answer:
c = 2
w = 18
x = 9
Step-by-step explanation:
When you have a power raised to a power, you multiply the exponents. If there are more than one term that are multiplied together, that exponent needs to go to both of the terms.
Also, if you have a negative exponent, you can change the sign of it by pushing that term across the fraction bar. see image.

a bowl has 3 red jellybeans,4 green jellybeans and 2 pink jellybeans. what is the probabilty of not choosing a red jelly beans
Answer:
1/2
Step-by-step explanation:
4+2 is green and pink jelly beans. 6. 3 is red. 3/6 is the probability, which is 1/2
Answer:
Step-by-step explanation:
Total Number of Jelly Beans = 3 + 4 + 2 = 9
There are two ways to do this. You could just add the pink and green jellybeans and put that over the total to get the probability of not red.
Sometimes it is better to find the probability of getting red and subtracting it from 1.
P(red) = 3/9 = 1/3
P(not red) = 1 - 1/3
P(not red) = 2/3
Find the area; reduce to lowest terms: Length: 3 2/3 feet; Width: 1/4 feet
Answer:
11/12 square feet
Step-by-step explanation:
The area is the product of length and width. Multiplication of mixed numbers is often easily done by converting to improper fractions.
A = LW
A = (3 2/3 ft)(1/4 ft)
A = (11/3)(1/4) ft² = 11/12 ft²
The area is 11/12 square feet.
if 4 friends eat 4 cakes in 4 days then how many cakes will 10 friends eat in 10 days
Answer:
If four friends can eat four cakes in four days, then four friends will eat an average of one cake per day, so each friend will be able to eat 1/4 of a cake per day.
So 10 friends will eat 10/4 of cake per day, or two and a half cakes per day, so they will eat 2,5 * 10 = 25 (twenty-five) cakes per 10 days, assuming they will eat at the same rate
