Adam,
because for John if you add 6+6 = 12 for 20 dollars where Adam has 13 for 20
Let
x--------> amount of erasers that Sari has
y--------> amount of erasers that Sam has
we know that
-------> equation ![1](https://tex.z-dn.net/?f=%201%20)
-----> equation ![2](https://tex.z-dn.net/?f=%202%20)
Substitute equation
in equation ![2](https://tex.z-dn.net/?f=%202%20)
![[3y]+y=28\\ 4y=28\\ y=28/4\\ y=7](https://tex.z-dn.net/?f=%20%5B3y%5D%2By%3D28%5C%5C%204y%3D28%5C%5C%20y%3D28%2F4%5C%5C%20y%3D7%20)
find the value of x
![x=3y\\ x=3*7\\ x=21](https://tex.z-dn.net/?f=%20x%3D3y%5C%5C%20x%3D3%2A7%5C%5C%20x%3D21%20)
therefore
the answer is
Sari has
erasers
Answer:
Choice D
Step-by-step explanation:
(9.1 x 10^5) - (9.3 x 10^4)
910000 - 93000 = 817,000 = 8.17 x 10^5
usually, you would want <u>a whole number</u> in standard notation
A. 0.817 x 10^6 = 817,000
B. 817 x 10^3 = 817,000
C. 8.17 x 10^4 = 81,700
D. 8.17 x 10^5 = 817,000
You will have 16 bars left.
Answer:
w = ( x - 10)
Step-by-step explanation:
area of the garden = x² - 25x + 150.
factorise the expression to find the x values.
x² - 25x + 150 = (x - 15)( x - 10) -15-10 = -25
-15*-10= 150
as the garden is rectangle, it's area will be = lw.
a = l × w
a = (x - 15)( x - 10)
one among them is the width, the other the length. if the length is (x - 15), then reasonably the width will be (x - 10).
hope this helps you, au revoir!
