Answer:

v=7

Step-by-step explanation:

add 15 to both sides 5v-15+15=20+15

simplify

5v=35

divide both sides by 5

5v/5 = 35/5

and you get 7

hope this helps you

Answer:

1.4 or 30.8

Step-by-step explanation:

1.4 is for regular math because it's basically 16.1 - 14.7

30.8 is for KCO or Keep Change Opposite (Beginners math)

Basically it would turn the equation into 16.1 + 14.7

You can use either but if you aren't sure ask your teacher about the strategy.

Hope this helps and if not tell me your strategy.

Answer:

y=kx

2=k.-4

k=-1/2

then

y=-1/2×20

y=-10

Answer:

y = - 10

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 2 when x = - 4, that is

2 = - 4k ( divide both sides by - 4 )

[tex]\frac{2}{-4}[/tex] = k, that is

k = - [tex]\frac{1}{2}[/tex]

y = - [tex]\frac{1}{2}[/tex] x ← equation of variation

When x = 20, then

y = - [tex]\frac{1}{2}[/tex] × 20 = - 10

Answer:

Step 1: take the total price and divide it by one plus the tax rate.

Step 2: multiply the result from step one by the tax rate to get the dollars of tax.

Step 3: subtract the dollars of tax from step 2 from the total price.

Pre-Tax Price = TP – [(TP / (1 + r) x r]

TP = Total Price

Answer:2.56^10

Step-by-step explanation:

Answer:

1,320

22 and 0,

6 and 22

0 + 1,320 = 1,320

Hope I helped! Plz leave a comment or rating to help me!

Answer:

Multiply 22 and 0 to get 0

Multiply 60 and 22 to get 1320

0 + 1,320 = 1,320

Step-by-step explanation:

When doing multiplication, you first start by multiplying the the bottom right number by the top right, then left numbers. In this case it’s 0, and multiplied by 0 is 0. In this case, since the first answer was 0, you just have to grab a calculator for 22 x 60

x first so five to the left so it's negative and if each gridline is .5 and were are 5 gridlines aver then .5*5 so -2.5 then y is up so positive and 3 lines so .5*3 so 1.5 so coordinate is (-2.5,1.5)

Answer:

The answer is 10.9

Step-by-step explanation

#1 think of the formula of the area

length x width = area

#2 do the oposite of what you would to to find the area to find the width

82.84➗7.6 = 10.9

#3 check your answer

7.6 x 10.9 = 82.84

#3 answer

width= 10.9

Answer:

34321.2 min

Step-by-step explanation:

The Burj Khalifa has in total 28601 windows. On the other hand, we are told the window-washing crew can wash 15 windows in 18 minutes. So, we can use the Rule of three to solve this problem:

If:

15 windows ---- 18 min

28601 windows ---- ?

Then:

? = (28601windows)(18min)/15windows

? = 34321.2min

Answer:

Step-by-step explanation:

Let's solve for b.

y=mx+b

Step 1: Flip the equation.

mx+b=y

Step 2: Add -mx to both sides.

mx+b+−mx=y+−mx

b=−mx+y

Answer:

b=−mx+y

I tried hope I helped

Answer:

b

Step-by-step explanation:

if malik is just paying interest and not the whole then b.

1,800 × 0.08 = 144, 144 × 3 = 432. the interest would be 432
