HELP I don’t understand

Answer:

7 1/5                 

Explanation:

Rewrite the decimal number as a fraction with 1 in the denominator

7.2=7.2/1

Multiply to remove 1 decimal places. Here, you multiply top and bottom by 10^1 = 10

7.2/1×10/10=72/10

Find the Greatest Common Factor (GCF) of 72 and 10, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 2,

7/2÷2/10÷2=36/5

Simplify the improper fraction,

=7 1/5

In conclusion,

−7.2=−7 1/5

Hope it helped. :)

ANSWER=30

because if you 8.2-2.3 you get  5.9 and if you divide by 177 it is 30

hope it helps

Answer:

Below

Step-by-step explanation:

6% simple annual interest on the loan for 3 years so 6x3=18

So the interest of the whole amount is 18%, so now you got to find what of 18% is 90

This looks like (initial amount)x(number)%=(final amount)

x=initial amount

number%=18

final amount=90

All percentages are just number%/100. So we have either 18/100, or .18 depending on how you want to work it.

So now we do 90÷0.18 which gives you the answer 500

Answer:

$6774.4

Step-by-step explanation:

Given data

P=$2900

r= 6.25%

t= 14 years

A=???

The compound interest formula is given as

A=P(1+r)^t

substiute

A= 2900(1+0.0625)^14

A= 2900(1.0625)^14

A= 2900*2.336

A= $6774.4

Hence the final amount is $6774.4

Answer:

4.25 m

Step-by-step explanation:

Resolvemos esta pregunta usando la fórmula:

Altura del hombre / Sombra de un hombre = Altura del palo / Sombra del palo

Sombra del hombre = 3.50 m

Altura de un hombre = 1.75 m

Sombra del palo = 8.50 m

Altura del palo = x

Por lo tanto:

1.75 / 3.5 = x / 8.5

Cruz multiplicar

1.75 × 8.5 = 3.5 × x

14.875 = 3.5x

x = 14.875 / 3.5

x = 4.25 metros

Por tanto, la altura del palo = 4.25 m

Answer:y=3x-4

Step-by-step explanation:

you add 5 on both sides

simplify

and get y on one side

slope is 3

the y intercept is -4

Answer:

slope = - 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 8,6) and (x₂, y₂ ) = (0, - 2) ← 2 points on the line

m = [tex]\frac{-2-6}{0+8}[/tex] = [tex]\frac{-8}{8}[/tex] = - 1

Answer:

the answer isnt 60 because i got that question wrong its 50

Step-by-step explanation:

Answer:

4y+7

Step-by-step explanation:

First, remove the unnecessary parenthesis. Add like terms (In this case it’s y) So it will be 6y-2y. Which gives you 4y. And then after that 10-3, which gives you 7. So your final answer is 4y+7!!

Answer:

I'm not sure I'm too lazy to do it lol

Step-by-step explanation:

Answer:

The slope is 1/4 so the slope intercept form is y=1/4+3

Step-by-step explanation:

To find the slope the easiest way from looking at a graph is just to find the rise over run. From looking at the graph we can see that the next point from 0,3 is 4,4. The y here is increased by 1, which means the rise is 1. The x is increased by 4 so the run is 4. From putting rise (1) over run (4) the slope is 1/4. The formula for slope intercept is y=mx+b. m is slope so we substitue that for 1/4 so now we have y=1/4x+b. Then the b is the y intercept, or, at what point the line crosses the y line. Which in this case is 0,3 so the y intercept would be 3 because that is what height it crosses the y line.

Answer:

[tex]y = 2 + \frac{1}{2}x[/tex]

Step-by-step explanation:

Given

Represent Carlos with y and his brother with x.

Analysing the statement one after the other:

Half of his brother's amount is: [tex]\frac{1}{2}x[/tex]

$2 more: means we add 2 to [tex]\frac{1}{2}x[/tex]

So, we have: [tex]2 + \frac{1}{2}x[/tex]

The above represent Carlos's amount.

So, the expression is:

[tex]y = 2 + \frac{1}{2}x[/tex]

Step-by-step explanation:

Answer:

The tree grew 15/64 meters per year.                  

Step-by-step explanation:

Given

To determine

Per year growth of the tree in meters

Per year growth of the tree in meters can be determined by dividing the total length of a tree i.e. 3/4 meters by the total time taken by the tree to get 3/4 taller.

Per year growth of tree = Total Length  / Total time to grow

                                       = 3/4 ÷ 16/5

                                        = 3/4 × 5/16

                                        = [3×5] / [4×16]

                                        = 15/64 meters

Therefore, the tree grew 15/64 meters per year.                  

Answer:

x = 2

Step-by-step explanation:

-5x + 8 = -2

-5x + 8 - 8 = -2 -8

-5x = -10

-5x/5 = -10/5

-x = -2

x=2

Simplify the equation:

-5x = 2 + 8

-5x = 10

x = -2
