Answer:

x=28

Step-by-step explanation:

So a triangle is 180 degrees in total then you would subtract 40 from 180 because the top angle and leaving you with 140 then divide by 5 because the bottom two getting you 28 then you could just plug in 28 for x on each angle

180-40=140

140/5=28

What does x equal? Dpsewbskdye
Mice21 [21]

Answer:

x = 7

Step-by-step explanation:

27 = 7x + 6 - 4x      (Given)

27 = 3x + 6             (Simplify)

27 - 6 = 3x + 6 - 6  (Subtract 6 on both sides)

21 = 3x                    (Simplify)

21/3 = 3x/3             (Divide 3 on both sides)

7 = x                        (Simplify)

eliot counts a group of coins staring with the quarters his sister counts the same coins she counting the pennies wiil they get
zalisa [80]

Answer: No, they would not get the same amount.

Step-by-step explanation:

Let the number of coins be x

Eliot counts a group of coins staring with the quarters.

As we know that

1\ quarter=25\ cents

So, Number of amount Eliot counts with the quarters is given by

25\times x=25x\ cents

Similarly, His sister counts the same coins she counting the pennies .

As we know that

1\ penny=1\ cent

So, Total amount his sister counts with  the pennies is given by

1\times x=x\ cents

But we can see that

25x\ cents\neq x\ cents

Hence, No, they would not get the same amount.
