Answer:

y-intercept is -10 and slope is 4

Step-by-step explanation:

in y= 4x-10 the slope is 4 because in the formula y=mx+b, m is the slope and the y-intercept is -10 because also in the formula y=mx+b, b is the y-intercept

The sum of two numbers is 48. If one third of one number is 5 greater than one sixth of another number, which of the following i

lubasha [3.4K]

The sum of two numbers is 48.
a + b = 48
;
If one third of one number is 5 greater than one sixth of another number,
a = b + 5
multiply both sides by 6, cancel the fractions
2a = b + 30
2a - b = 30
use elimination to solve this
a + b = 48
2a - b =30
-------------Addition eliminates b, find a
3a = 78
a =
a = 26
then
26 + b = 48
b = 48 - 26

b = 22

If you have 30$ and you need to find 8%, and add to 30$ then find 15% of that, and what’s your total?

stira [4]

Answer:

Our total amount value is $4.86.

Step-by-step explanation:

The total amount given is $30.

Now 8 % of $30 = $\frac{8}{100} \times 30 = 2.4$

or, 8% of $30 = $2.4

Now adding $30 and $2.4,

$ 30 + $2.4 = $32.4

Finding 15% of the total $32.4,

we get $\frac{15}{100} \times 32.4 = 4.86$

or, 15% of $32.4 = $4.86

hence, our total amount value is $4.86.

A plane descended 922.02 meters in 5.5 minutes. What is the plane's rate of descent?

UkoKoshka [18]

The rate of descent is 164.64 meters / minute

To get this answer you just divide the total number of meters descended by the total number of minutes passed.

So:

922.02 ÷ 5.5 = 164.64

I hope this helped!! Have an amazing day! :D
