Answers

Answer 1

Answer: 8 cakes ... 4.00
3 cakes ... x = ?

If you would like to know how much do 3 cakes cost, you can calculate this using the following steps:

8 * x = 4 * 3
8 * x = 12 /8
x = 12/8
x = 3/2 = 1.5

The correct result would be 1.5.

Answer 2

Answer: three cakes equals $1.50
because.....
8 divided by $4.00 equals 2
so 3 divided by 2 equals $1.50

Answer:

Multiply 2x + 3y = −1 by 5. Multiply 3x − 5y = 10 by 3. Add the resulting equations together.

Step-by-step explanation:

To eliminate the y-term. we must multiply both equations by values that make the coefficients of y opposite in sign.

2x + 3y = -1 (1)

3x - 5y = 10 (2)

The easiest way to do this is to multiply Equation (1) by 5

and Equation (2) by 3.

5 × [2x + 3y = -1]

3 × [3x - 5y = 10]

Then, add the two equations.

10x + 15y = -5

9x - 15y = 30

19x = 25

Conclusion: Multiply 2x + 3y = −1 by 5. Multiply 3x − 5y = 10 by 3. Add the resulting equations together.

Answer:

LM = 2(MP)

Step-by-step explanation:

The radius KN is perpendicular to LM meaning that the line is split in half at the crossing. Review properties of circles to see why this is true.

Since we know this, we can say LM = LP + MP. And LP = MP.

So we can say LM = 2(MP).

Which of the following correctly shows the quotient of 75 divided by 5?5/75 = 12
75/5= 15
75÷5= 25
75÷5= 70

Answers

The correct quotient of 75 divided by 5 is 15.

When you divide 75 by 5, you are essentially asking how many times 5 can be evenly divided into 75. To find the quotient, you divide 75 by 5:

75 ÷ 5 = 15

This means that 5 can be divided into 75 exactly 15 times.

Therefore, the quotient is 15.

There are 49,000 seats in a sports stadium. Tickets for the seats in the upper level sell for $25, the ones in the middle level cost $30 and the ones in the lower level are $35 each. The number of seats in the middle and bottom levels together equal the number of seats in the upper level. When all of the seats are sold for an event, the total revenue is $1,419,500. How many seats have been sold in the upper level?

Answers

u- amount of upper level tickets which cost 25$
m-amount of middle level tickets which cost 30$
b-amount of bottom level tickets which cost 35$

m+b=u and
m+b+u=49000 and
25u+30m+35b=1419500

putting u from first equation to the second
2u=49000
u=24500 - seats in upper level
m+b=24500 so m=24500-b
25*24500+30(24500-b)+35b=1419500
612500+735000-30b+35b=1419500
1347500+5b=1419500
5b=72000 /:5
b=14400 amount of seads in bottom level

Find f(a), f(a+h) and the difference quotient (f(a+h)-f(a))/ h, where hod want equal 0. F(x)= 2x/ x-1

Answers

First.

Calculate f'(x) = (2x/x-1)' = (-2)/ $(x-1)^(2)$ ; when x is not 1;

Second.

Calculate f'(0) = -2 => the difference quotient (f(a+h)-f(a))/ h, where hod want equal 0 is -2;

Third.

f(a) = 2a/a-1; f(a+h) = (2a+2h)/(a+h-1);
