Answer:

✑ [tex] \underline{ \underline{ \sf{First ,\: Let's \: learn \: about \: the \: ratio}}} : [/tex]

Let us consider , there are 30 boys and 40 girls in a school. So, the ratio of number of boys to number of girls = [tex] \sf{ \frac{30}{40} = \frac{3}{4} = 3:4}[/tex] and read as 3 is to 4. We can say , the ratio compares two of more quantities of same unit. Until two quantities have same units , it is meaningless to compare by ratio. So, to find the ratio of two quantities , it is necessary to express them in same unit or of same kind. Since , they are in division form. So ,ratio is unit less quantity. Thus , the ratio is a comparison of two quantities of the same kind in division which doesn't have any units. For example : [tex] \sf{ \frac{a}{b}} [/tex] is a ratio and is read as ' a is to b ' in which ' a : is antecedent and ' b ' is called consequent.

✎ [tex] \underline{ \underline{ \sf{Now \: let's \: solve : }}}[/tex]

☪ [tex] \underline{ \sf{Solution}} : [/tex]

£ 21 is to be divided between Amy and Ben in the ratio 5 : 2. So, let Amy get £ 5x and Ben get £ 2x.

Then , According to the question , [tex] \text{5x +2x = 21}[/tex]

Solve for x :

⇝ [tex] \sf{7x = 21}[/tex]

⇝ [tex] \sf{ \frac{7x}{7} = \frac{21}{7} }[/tex]

⇝ [tex] \sf{x = 3}[/tex]

The value of x is 3. Now , substitute the value of x in 5x :

Amy received £ 5x = 5 × 3 = £ 15 .

☥ [tex] \boxed{ \boxed{ \tt{Our \: final \: answer \: is \bold{£ \: 15}}}}[/tex]

Step-by-step explanation:

5x and -7x are like terms

5x-7x+9=-2x+9 and there's your equivalent expression

Answer:

i want to say 7x is the answer

Step-by-step explanation:

because if you add 5x to 9 = to 14 the -7 = to 7x

Step-by-step explanation:

£280 is 7% of 4000 so £4000 euro more would be 4000/280 = 14

Step-by-step explanation:

-20 > -2x + 4

2x > 4 + 20

2x > 24

x > 12

or

x ∈ 《12 , + ∞》

-20 > -2x + 4

-20 -4 > -2x

-24 > -2x

-24/-2 < x  <inequality changes when you divide by a -ve no. >

12 < x

Answer: ↓↓↓

Step-by-step explanation:

a.) 100 - 10^2

b.) 10,000 - 10^4

c.) 100,000 - 10^5

d.) 10 - 10^1

e.) 1000 - 10^3

f.) 1,000,000 - 10^6

What I do personally is that I count the number of zeros in the number and that is how many powers the ten powers to. Like a, there are two zeros in 100 so its 10 to the power of 2.

Answer:

SAME AS THIS

Explanation:

County A: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!

$75 * 0.0725 = $5.4375

Add the original price and the sales tax.

$75 + $5.4375 = $80.4375

County B: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!

$70 * 0.08 = $5.6

Add the original price and the sales tax.

$70 + $5.6 = $75.6

Then take the difference.

80.4375 – 75.6 = 4.8375

Round to the nearest hundredth: $4.84

Answer:

the sale price would be $78

Step-by-step explanation:

add up all the prices to get 120

35% taken off of 120 is 78

Answer:

$200. had to edit, read the question wrong originally

=======================================================

Work Shown:

If you save 64%, then you still have to pay the remaining 100% - 64% = 36%

x = original price in dollars

sale price = 36% of x = 0.36*x = 72

0.36*x = 72

x = 72/0.36

x = 200

The original price is $200

discount = 64% of 200 = 0.64*200 = 128

You save $128

The amount you pay is 200-128 = 72 dollars, which matches with the given sale price.

Answer:

she will be back at 7:30pm

Step-by-step explanation:

From the question we are given

Time that Shasta leaves for her best friend place = 5:00pm

If she is to come back after 2 and a half hour, hence we will have to add 2hr 3ominutes to the time she left to know the time she will be back as shown:

She will be back at 5:00 + 2hr 30min = 7:30pm

Hence she will be back at 7:30pm

Answer:

B

Step-by-step explanation:

using the back to back numbers 1 and 5, you can tell that each number goes up by 4. ex: -7+4=-3+4=1+4=5+4=9+4=13 and so on

Answer:

The distance measure is 4.2 ft

Step-by-step explanation:

Here, we want to get the distance from the bottom of the ladder to the side of the house

To get this, we can see that what we have is a right-angled triangle

We need to apply the appropriate trigonometric identity to get the value of what we want

Let us call the measure we want to calculate x

Mathematically;

Tan 72 = 13/x

x = 13/tan 72

x = 4.2 ft

Answer:

a) x=7

b) x=4

c) x= 1/9

Answer:

16+c=25

Step-by-step explanation:

Answer:

$26.25

Step-by-step explanation:

we can convert 25% directly to a decimal:

25% = 0.25

Then we find

25% of 35 = 0.25 x 35 = 8.75

35 - 8.75 = 26.25

So the jeans on sale cost $26.25

the sale price of the jeans will be $26.25

Answer: "YOUR ON PROBLEM ONE !"

Step-by-step explanation:

Answer:

283.19

Step-by-step explanation:

Find the number in the hundredth place  9  and look one place to the right for the rounding digit  2 . Round up if this number is greater than or equal to  5

and round down if it is less than  5 .

Answer:

283.19

Step-by-step explanation:

So as you should already know, the 2 is the hundreds, 8 is the tenths, and 3 is the ones, but you may not know the ones after it. The number after the little dot (decimal) is a 1 and is called the tenths and the one after is the hundredths and then thousandths and so on. You want to know the hundredths so just keep all of the numbers until you get to the number that is 2 places after the decimal and look at the last number and if its below 5, keep the hundredths the same but if its 5 or over make the hundredths 1 higher. for example 3 stays the same because the next number is below 5. This is how you do rounding with decimals! Please give Brainliest if this helps!

Answer:

direct variation equation: y = 13/4x

y = -19.5 when x = -6

Step-by-step explanation:

y = kx  where 'k' is the constant to proportionality

13 = 4k

k = 13/4

equation:  y = 13/4x

plug in -6 for 'x' to find value of 'y'

y = 13/4(-6)

y = -19 1/2

Answer:

y=3x+3
