Answer:

Solution=−72

Step-by-step explanation:

Combine multiplied terms into a single fraction−18=14−18=14. Multiply by 1. Multiply all terms by the same value to eliminate fraction denominators. Cancel multiplied terms that are in the denominator. Multiply the numbers. Move the variable to the left.

Answer:

5

Step-by-step explanation:

So let's start with making an equation,

125 x A = 625         Note: A is just a variable for the missing number

125A / 125 = 625 / A

A = 5

So, the missing number is 5

*view attached graph*

Answer:

Original #: 950

New #: 1,520

If it is percent of increase, you would do new amount - original amount over original amount.

1,520 - 950 / 950 = 570 / 950

0.6 or 60%

The store which has the lower total price is B, lower by $1040.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

Given;

Store B sells the same computer as in the Example for $1,300.

Store B offers a 20% discount on the computer.

Now

Store B offers a 20% discount on the computer,

CB= CA-0.2CA

CB=1300-0.2-1300

CB= 1300-260

CB=1040

Therefore, the cost by 20 percent will be $1040.

Answer:

vertical : horizontal = 1 : 2

Explanation:

UT, vertical length: 3 units

ST, horizontal length: 6 units

Therefore vertical length : horizontal length = 3 : 6 = 1 : 2

Answer:

1:2

Step-by-step explanation:

Triangle PQR has a vertical side of 1 and a horizontal side of 2.

so the ratio is vertical : horizontal is 1:2

Triangle STU has a vertical side of 3 and a horizontal side of 6.

so the ratio is vertical : horizontal is 3:6

which can be reduced by dividing both sides by 3

so the ratio is vertical : horizontal is 1:2

Answer:

30

Step-by-step explanation:

The Pythagorean Theorem is c2 (c squared) = a2 (a squared) + b2  (b squared).

The side lengths (24 and 18) can be plugged in for a and b. C is the length of the hypotenuse.

24 Squared + 18 Squared= c squared

Use a calculator to help you.

24 squared is 576

18 squared is 324

So, 576+324=c squared

Simplify

900=c squared

Now use the squre root on both sides to get rid of the c squared. (use a calculator)

30=c

Answer:

0.365 kg

Step-by-step explanation:

I hope this explains it and helps :)

Answer:Answer:

0.365 kg

Step-by-step explanation:

The first I did was turn the 250mg to grams so the conversion factor would be 1 milligram = 0.0001 gram.

Divide the 250mg by 1000g to get 0.25g.

Multiply 0.25g by 60 to get 15g.

Add 15g to the weight of the empty basket, 350g. You should end up with 365g.

The question asked for kilograms so divide 365g by 1000.

The final answer is 0.365kg.

I hope this explains it and helps :)

this is pretty simple! there are three dictionaries.

if all three dictionaries together have 1200 words, then each dictionary will have 1/3 of 1200 words. this is 400.

if each dictionary has 400 words, eight dictionaries will have 400*8 which is 3200 words.

Answer:

x = 6 is a solution of x - 1 [tex]\leq[/tex] 7.

Step-by-step explanation:

First, plug in x = 6 into the inequality.

x - 1 [tex]\leq[/tex] 7 for x = 6

6 - 1 [tex]\leq[/tex] 7

Now, solve.

6 - 1 = 5

5 [tex]\leq[/tex] 7

The statement above is true, so x = 6 is a solution to x - 1 [tex]\leq[/tex] 7.

Answer:

a. geometric sequence

b. an = 5(2)^n-1

c. an+1 = an x 2

Step-by-step explanation:

The sequence: 5, 10, 20, 40,...

a. The sequence is geometric because the sequence has a common ratio of 2, each number is made by multiplying the previous number with the common ratio (2).

b. The explicit formula for this sequence is an = 5(2)^n-1

The explicit formula for a geometric sequence is

an = a1 (r)^n-1

Substituting that with the values we know, we will get

an = 5(2)^n-1

c. The recursive formula for this sequence is an+1 = an x 2

The recursive formula for a geometric sequence is

an+1 = an x r

Substituting for the values we know, we get

an+1 = an x 2
