Answer:
y = 2
Step-by-step explanation:
Given
[tex]\frac{2y-1}{15}[/tex] = [tex]\frac{y}{10}[/tex] ( cross- multiply )
10(2y - 1) = 15y ← distribute left side
20y - 10 = 15y ( subtract 15y from both sides )
5y - 10 = 0 ( add 10 to both sides )
5y = 10 ( divide both sides by 5 )
y = 2

Translate the following verbal expression into a variable expression.
Eight divided by the sum of a number and three.
Answer:
8÷(x+3)
Step-by-step explanation:
it doesnt specify what number you add with 3 so you substitute it with a variable such as x.
The sum is adding so x +3 and then divide by 8
what are the answers to these?!?!?!?>>>>>
2(y−3)=4 (solve for "y")
2x+5y=10 (solve for "x")
6x+3y=4y+11 (solve for "y")
3(2x+4)=2+6x+10 (solve for "x")
y=−3x+6 (solve for "x")
m=8−2(p−m) (solve for "p")
1) y=5
2) x=(10-5y)/2
3) y=(11-6x)/-3
4) x=0
5) x=(-y+6)/3
6) p=(8+m)/2

If a bowling ball is dropped out of an airplane,
what will its speed (velocity) be after 3.4
seconds, assuming no air resistance? (Hint: Use
the equation v = 32t).
Answer: The velocity of the ball is 108.8 ft/s downwards.
Step-by-step explanation:
When the ball is dropped, the only force acting on the ball will be the gravitational force. Then the acceleration of the ball will be the gravitational acceleration, that is something like:
g = 32 ft/s^2
To get the velocity equation we need to integrate over time, to get:
v(t) = (32ft/s^2)*t + v0
where v0 is the initial velocity of the ball. (t = 0s is when the ball is dropped)
Because it is dropped, the initial velocity is equal to zero, then we get:
v(t) = (32ft/s^2)*t
Which is the same equation that we can see in the hint.
Now we want to find the velocity 3.4 seconds after the ball is dropped, then we just replace t by 3.4s, then we get:
v(3.4s) = (32ft/s^2)*3.4s = 108.8 ft/s
The velocity of the ball is 108.8 ft/s downwards.

Jessica school bus stop is 60 yards from her house.For a normal school week, how many feet will Jessica walk to and from the bus stop?
A 300 feet
B 600 feet
C 900 feet
D 1,800 feet
winner gets 100 points
Answer:
d
Step-by-step explanation:
school is only 5 days a week and if she walks 60 yards to the bus stop and 60 yards back from the bus stop than she walks a total of 120 yards a day
120 x 5 =600 the answers are in feet so we need to convert to feet and to do that we need to multiply by 3
600x3=1800
so she walks 1800 feet in a normal school week

Solve the equation:
7x − 2 = 26
Answer:
[tex] \large \boxed{x = 4}[/tex]
Step-by-step explanation:
Goal
Solve for x-term.Given
Equation[tex]7x - 2 = 26[/tex]
Step 1
Isolate x by adding 2 to both sides.[tex]7x - 2 + 2 = 26 + 2 \\ 7x + 0 = 28 \\ 7x = 28 \\ x = \frac{28}{7} \\ x = 4[/tex]
Step 2 (Optional)
We check the answer by substituting x = 4 in the equation.[tex]7x - 2 = 26 \\ 7(4) - 2 = 26 \\ 28 - 2 = 26 \\ 26 = 26[/tex]
The equation is true for x = 4. Hence, the solution is x = 4.

Answer: 38
Step-by-step explanation:
Answer:
Perimeter= 38, EC- Area= 19.5
Step-by-step explanation:
substitute all the x's for 5. simplify each equation. H=3, Base= 13, 4x+2=22
h- 5-2=3
4(5)+2=22
base- 2(5)=3=13
then add all answers together to get 38.
multiply 13 and 3 to get 39, then divide by 2 to get 19.5 for the area.
Use substitution. What is the solution to the system of equations? Use the drop-down menus to explain your answer.

What are arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per the given data in the question,
Distance (d) traveled by the horse = 0.5 miles
Time (t) taken by the horse to cover the distance = 1.25 minutes
Then, the speed of the horse will be,
[tex]Speed=\frac{Distance}{Time}[/tex]
s = 0.5/1.25
s = 0.4 miles/minute.
