a) biswant thought of a number. he double it and added 5. if he got 13, find the number he thought
Answer:
Four
Step-by-step explanation:
13- 5= 8
8/2=4
You simply do the problem in reverse.
Answer:
The number is 4
Step-by-step explanation:
Let the number = x
Double of x = 2*x = 2x
Then add 5 to it: 2x +5
2x +5 = 13
Subtract 5 form both side
2x + 5 - 5 = 13 - 5
2x = 8
Divide both sides by 2
x = 8/2
x = 4

if 5t=5 then t is what number
Answer:
1
Step-by-step explanation:
5t = 5
divide equation by 5 to get rid of it
t = 1
This is because 5t means "5 times t". The t is a placeholder for a number.
To solve for t, we divide both sides by 5
5t = 5
5t/5 = 5/5
t = 1
Note how 5t = 5 becomes 5*1 = 5 after replacing t with 1. Because 5*1 = 5 is a true statement, this helps confirm we have the correct answer.
The indoor climbing gym is a popular field trip destination. This year the senior class at High School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 3 vans and 12 buses with 504 students. High School B rented and filled 2 vans and 4 buses with 184 students. Every van had the same number of students in it as did the buses. Find the number of students in each van and in each bus.
High school A: 3 vans + 12 buses = 504 students
High school B: 2 vans + 4 buses = 184 students
Multiply High school B by 1.5:
High school B: 3 vans + 6 buses = 276 students
Subtract High school B from High School A:
6 buses = 228 students
Divide students by buses:
Buses = 228 / 6 = 38 students per bus
Now solve for vans using high school A:
3 vans + 12(38 students per bus) = 504 students
Simplify:
3 vans + 456 students in buses = 504 students
Subtract students in buses from both sides:
3 vans = 48
Divide both sides by 3:
Vans = 16
Answer: vans = 16 students, buses = 38 students

The triangles are congruent with SSS postulates. Then the correct option is D.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
Two triangles are shown.
The SSS postulate is one of the ways to prove that two triangles are congruent. SSS stands for "side-side-side," and it states that if three sides of one triangle are congruent to the corresponding sides of another triangle, then the two triangles are congruent.
The corresponding sides of the triangle will be equal. Then the triangles are congruent with SSS postulates.
Thus, the correct option is D.

296 divide by 0.08 whats the answer plz answer, and show me how you did it plz
Answer:
Step-by-step explanation:
Ok so u can’t divide a decimal with a whole number so u have to move the decimal poin from the 8 twice so it’s on the other side of the 8 and then there shouldn’t be any zeros before the 8 now divide 296 by 8 and instead of leaving the whole number like that u have to add the decimal point to it. So it should look like this 296.00 and then u can divide which is 3,700 hope this helped <3

If 3 and 5 are factors of a number, then
15 is a factor of the number.
Answer:
factors of 15 are 3 and 5, because 3×5 = 15. Some numbers have more than one factorization (more than one way of being factored).
Step-by-step explanation:
The given statement, "If 3 and 5 are factors of a number, then
15 is a factor of the number", is true as the lowest common multiple of 3 and 5 is 15.
What do we mean by factors of a number?A number x is said to be a factor of another number y when y/x leaves a remainder = 0.
How do we solve the given question?In the question, we are asked that if 3 and 5 are factors of a number, then will 15 also be a factor of that number.
The smallest number with the factors 3 and 5 is 15, as the lowest common multiple of 3 and 5 is 15. Hence, the number we are looking for is a multiple of 15, that is, 15 is a factor of that number.
∴ We can say that any number having factors 3 and 5, will have a factor of 15. Hence, the given statement is true.

The line joining (3, p) to (7, –4p) is parallel to the line joining (–1, –3) to (3, 7). Find p.
Answer:
p = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, - 3) and (x₂, y₂ ) = (3, 7)
m = [tex]\frac{7-(-3)}{3-(-1)}[/tex] = [tex]\frac{7+3}{3+1}[/tex] = [tex]\frac{10}{4}[/tex] = [tex]\frac{5}{2}[/tex]
Parallel lines have equal slopes
Calculate the slope of the other 2 points and equate to [tex]\frac{5}{2}[/tex]
with (x₁, y₁ ) = (3, p) and (x₂, y₂ ) = (7, - 4p)
m = [tex]\frac{-4p-p}{7-3}[/tex] = [tex]\frac{-5p}{4}[/tex] = [tex]\frac{5}{2}[/tex] ( cross- multiply )
- 10p = 20 ( divide both sides by - 10 )
p = - 2

= 7q(7q-5) - 5(7q - 5)
= (7q-5) (7q-5)
= (7q-5)²
CMIIW
Answer:
Step-by-step explanation:
49q² -70q +25 , rewrite the first two terms as squares
(7q)² -70q + 5² , compare with a² - 2ab + b² = (a-b)²
a² - 2ab + b²
(7q)² -2(7q)(5 )+ 5², because 70q = 2*35q = 2*7*5*q
We can see that a = 7q and b=5, therefore
49q² -70q +25 = (7q -5)²
We set the equation equal to 0 to find the roots
7q-5 =0, add 5 to both sides
7q =5 , divide both sides by 7
q = 5/7 ≈ 0.714

You have cup of cocoa in your cupboard. A recipe for cookies calls for 1
cup of cocoa. How much cocoa would you have left if you made the cookies?
Answer:
None
Step-by-step explanation:
sorry don't know how to delete this
Hi! I'm happy to help!
The recipe calls for 1/4 of a cup of cocoa, and we have 5/6 of a cup.
We use subtraction to solve for the difference:
5/6-1/4
To solve for this, we need to find a common denominator. We do this by finding the least common multiple of the two denominators we already have.
The least common multiple is 12, because that is the lowest number that both 6 and 4 are factors of.
We multiplied the 6 by 2 to get twelve, so, to make it equivalent, we have to multiply the 5 by 2 also.
10/12-1/4
Now, since we multiplied the 4 by 3 to get twelve, we need to do the same to the 1.
10/12-3/12
You never subtract denominators, only numerators. Now, all we have to do is 10-3:
10/12-3/12=
7/12
So, you would have 7/12 cup of cocoa left over if you made the cookies.
I hope this was helpful, keep learning! :D
how do you convert a repeating decimal in the 10000 place into a fraction?
Decimal to Fraction
Converting any terminating decimal into a fraction is fairly straightforward. You count the number of decimal places, move the decimal point that number of places to the right, and put the resulting number over "1" followed by that number of zeroes.
For instance:
Convert the decimal 0.7 into a fraction.
This decimal has one decimal place, so I move the decimal point one place to the right, to get 7. Then I put this over "1" followed by one zero (otherwise known as "10") to get: 7/10
