Answer:

Step-by-step explanation:

6x-9y=3

+x-9y=-22

first you take x-9y=-22 *-1  which will equal -x+9y=22

then you add

6x-9y=3

+-x+9y=22

----------------

5x=25

÷5    ÷5=  x=5         then you plug  5 into each x spot

On monday ,jan made wgitmddrawls of $25,$45 and $75 from her savings account .On the sane day, het twin sister lola made withdra
Dafna11 [192]
Part (a):
We will assume that the total amount is Jan's saving account is "m"
Now, "withdrawal" means that she took money from her account, which means that the amount of money in her account decreased by the amount she withdrew.
Sum of negative integers to show her withdrawals = -25$ - 45$ - 75$
Amount of money remaining in her account = m - 145$
The amount of money Jan withdrew = 25$ + 45$ + 75$ = 145$

Part (b):
We will assume that the total amount is Lola's saving account is "n"
Now, "withdrawal" means that she took money from her account, which means that the amount of money in her account decreased by the amount she withdrew.
Sum of negative integers to show her withdrawals = -35$ - 55$ - 65$
Amount of money remaining in her account = n - 155$
The amount of money Lola withdrew = 35$ + 55$ + 65$ = 155$

John paid $32.16 for groceries. This included 7% sales tax. What was the cost of groceries before the sales tax? A. $2.25 B. $30
hoa [83]
If 32.16 includes the sales tax....then the price before the sales tax will be less then 32.16

that only leaves 2 choices.....
so lets check them...
7% sales tax on 2.25 = 0.07(2.25) = 0.16....so if u spent 2.25 on groceries and added the sales tax of 16 cents....then u would have spent 2.41...thats a long way from 32.16

if u spent 30.06...with 7% sales tax....u would spend 30.06 + 0.07(30.06) = 32.16

so the cost of the groceries before the sales tax is 30.06 <==
