Answers

Answer 1

Answer: 18/26, 27/39, 36/52, there are more than one

Answer 2

Answer: Since it cant be simplified any further, we just multiply a constant to both the numerator and the denominator to find an equivalent fraction
$(9*2)/(13*2)$ = $(18)/(26)$
or multiply by 3, or 4 and so on.........

Two types of tickets were sold for a concert held atan amphitheater. Tickets to sit on a bench during the
concert cost $75 each, and tickets to sit on the lawn
during the concert cost $40 each. Organizers of the
concert announced that 350 tickets had been sold
and that $19,250 had been raised through ticket sales
alone. Which of the following systems of equations
could be used to find the number of tickets for bench
seats, B, and the number of tickets for lawn seats, L,
that were sold for the concert?

Answers

Answer:

BENCH:150

LAWN:200

Step-by-step explanation:

B+L=350

75B+40L=19250

75B+40(350-B)=19250

75B+14000-40B=19250

75B-40B=5250

35B=5250

B=150

L=200

Which of these numbers are exactly divisible by 9? 107,513,944,126,80

Answers

513 and 126 both are. (The question doesn't say
that there's only one of them in the list.)

Here's an easy way to tell: (I don't know how or why it works,
but it works.)

You're looking at a big number, and you need to find out if it's
divisible by 9.
Here's the two-step process:
-- If it's going to be divisible by 9, then it has to be divisible by 3.
-- Find out whether it's divisible by 3. If it is, then ...
-- Find out whether it's divisible by 9.

Step 1:
Add up all the digits in the number. If that sum is divisible by 3,
then the original big number is too.

Example:
Is 549 divisible by 3 ?
Add up its digits: (5 + 4 + 9) = 18 .
Is 18 divisible by 3 ?
Yes. That tells you that 549 is divisible by 3 .
So it could be divisible by 9.

Step 2:
Take that same 18 and add up its digits.
(1 + 8) = 9.
9 is divisible by 3.
This tells you that the original big number ... 549 ... is also divisible by 9 .

Jacob is solving the equation below using successive approximations.2^x-4=3^-x-2 He started from a graph where he found the solution to be between 1 and 2. Using the lower and upper bounds from the graph, Jacob did the following work for the first iteration. Step 1 Rewrite the equation so that it equals zero on one side. Step 2 Evaluate the rewritten equation at the lower and upper bounds. To find the solution that lies between 1 and 2, set these values as the lower and upper bounds while finding the solution. Step 3 Take the average of the lower and upper bounds. Step 4 Evaluate the rewritten equation at x = . Step 5 Since this value is positive, replace the previous lower bound so that the bounds are now x = and x = 2. Where did Jacob make a mistake, and what was the error?

Answers

The mistake made by Jacob is; D: Jacob made a mistake at step 5. He should have used x=32 as the new upper bound.

How to Solve Successive Approximations?

In Mathematics, successive approximation can be defined as a classical method that is used in Calculus for solving integral equations or initial value problems.

In this question, Jacob started the first iteration of successive approximation by using the lower and upper bounds of the graph. However, we can deduce that Jacob made a mistake instep 5 because he should have used x = 3/2 as the new upper bound.

6( 5-8x) +12= -54I need help I didn't understand this problem it's really hard to solve it doesn't make sense to me please help?

Answers

6( 5-8x) +12= -54
30-48x+12=-54 this comes from distributing(multiplying) 6x5 and 6 times -8x
30+12-48x=-54 you have to add the coefficients 30+12
42-48x=-54
-42 -42
-----------------------
-48x=-96 divide by -48
x=2

You use the distributive property by distributing the 6 to 5 and -8x which gives you 30-48x+12=-54 then you subtract 30 and 12 from both sides to get -96 then divide by -48 to solve for x which gives you 2
