Answer 1

Answer: I think the answers below are all correct! :)

Step-by-step explanation: --> (that sign means I simplified the equation)

9-7r=-5 --> (9+5)-7r=0 --> 14-7r=0 --> 14=7r --> r=2

6x-5=4x+9 --> 6x=4x+(9+5) --> 6x=4x+14 --> 6x-4x=14 --> 2x=14 --> x=7

3(2d-1)=7d --> *multiply the parenthesis* 6d-3=7d --> -3=7d-6d -->d=-3

2(p-3)=4(3p+1) --> *multiply the parenthesis* 2p-6=12p+4 --> -10p=10 --> p=-1

Find the value of X

Answers

Answer:

80

Step-by-step explanation:

This quadrilateral is a kite

And the kite as its opposite angles equal

So based on this we can solve for x

[tex]100 + 100 + x + x = 360[/tex]

(360 here is the total sum of interior angke in a quadrilateral)

[tex]200 + 2x = 360 \\ 2x = 360 - 200 \\ 2x = 160 \\ x = \frac{160}{2} \\ x = 80[/tex]

Thisbis your answer hope it helps :))

Dominica $2000 for 3years at an interest rate of 7% how much interest did she earn on her money?​

Answers

Answer:

$420

Step-by-step explanation:

The formula for simple interest is i = prt, where p is the principal, r is the annual interest rate expressed as a decimal fraction, and t is the number of years.

Here p = $2,000, r = 0.07 and t = 3 yr, and so

i = ($2,000)(0.07)(3) = $420 was the amount of interest earned.

On a map, 1 inch equals 10 miles. Two cities are 8 inches apart on the map. What is the actual distance between the cities? The actual distance between the cities is miles.​

Answers

Answer:

the actual distance between the cities is 80 miles

Step-by-step explanation:

The computation of the actual distance between the cities is shown below:

As we know that

1 inch = 10 miles

So for 8 inches it would required 80 miles

i.e.

= 8 × 10

= 80 miles

Hence, the actual distance between the cities is 80 miles

Step-by-step explanation:

Given

[tex]BCA = 50[/tex]

[tex]DCA = 60[/tex]

See attachment for parallelogram and complete question

Required

Find ADC

From the attachment:

[tex]BCD = BCA + DCA[/tex]

[tex]BCD = 50+60[/tex]

[tex]BCD = 110[/tex]

Adjacent angles add up to 180.

So:

[tex]ADC + BCD = 180[/tex]

[tex]ADC = 180-BCD[/tex]

[tex]ADC = 180-110[/tex]

A+5 expressed as a difference

Answers

Answer:

A-(-5) = A+5

it is the answer

Answer:

a-(-5)

Step-by-step explanation:

Since it's originally an addition question but you want to write it as a difference (subtraction) question, you would use double negative signs. Whenever there are two double negatives next to each other, it counteracts and becomes a positive sign, however you still wrote it as a subtraction question.

Hope this helps

Answer:

  y = 3x -6

Step-by-step explanation:

The three turning points of the terms divide the graph into 4 pieces. We can consider what functions apply in each piece.

x < -2

All terms are negated:

  y = (3 -x) -(x +2) -(5 -x) = -x -4

-2 < x < 3

The first and last terms are negated:

  y = (3 -x) +(x +2) +(x -5) = x

3 < x < 5

The last term is negated:

  y = (x -3) +(x +2) +(x -5) = 3x -6

5 < x

No terms are negated:

  y = (x -3) + (x +2) -(x -5) = x +4

_____

In the region of interest, the equation simplifies to y = 3x -6.

Pancake Palace puts a pint of maple syrup on each one of their 16 tables. The owner is filling the syrup bottles before the restaurant opens. If the bottles are half full, how many quarts would he need to fill the bottles?

Answers

Answer:

64 quarts of maple syrup needed

Step-by-step explanation:

There are a total of 2 quarts in a 1 pint. Therefore, since there are a total of 16 tables and each one has 1 pint, then there are a total of 16 pints in the restaurant. If we multiply this by 2 we get the total amount of quarts of maple syrup in all of the tables

16 * 2 = 32 quarts of maple syrup

Since the bottles are only half full we need to multiply this amount by 2 in order to get the total syrup needed to have all of the bottles filled completely.

32 * 2 = 64 quarts of maple syrup needed

Answer:

4 Quarts

Step-by-step explanation:

You need to find how much maple syrup the owner needs to fill the bottles. But first, you need to find how much syrup the bottles hold in all.

There are 16 bottles. Each bottle holds 1 pint of maple syrup. So, the bottles hold a total of 16 pints of syrup.

Now, find how much maple syrup the owner needs. The bottles hold a total of 16 pints of syrup. Because they are half full, divide by 2.

16÷2=8

The owner needs 8 pints of maple syrup, but the problem asks about quarts. So, find how many quarts are equal to 8 pints. There are 2 pints in a quart, so divide by 2.

8÷2=4

The owner needs 4 quarts of maple syrup to fill the bottles.
