Answer:
-10.4
Step-by-step explanation:
-1.3(8)=-10.4
If she gets 3% of what she sells you multiply the decimal form of the percent by the amount she has made:
50*.03=1.5
So she make $1.50 for every $50 of sales, so you multiply the amount she made by her commission each day by the number of days she worked:
1.5*30=45
She earned a total of $45<span />
first equation equivalent to
4x+8y=28
substract with second equation
-2x=22
divide with -2
x=-11
substitute to first equation
8y=28-4(-11)
8y=72
divide with 8
y=9
so the solution is (-11,9)
Answer:
Step-by-step explanation:
<h3>Now turn the answer upside down</h3>
Step-by-step explanation:
I understand the equation is
4mA = d - f³
to solve for A means to bring A alone on one side of the equation, and everything else to the other side of the equation.
1. remove the factor 4 from A by dividing both sides by 4.
mA = (d - f³)/4
2. remove the factor m from A by dividing both sides by m.
A = (d - f³)/4/m = (d - f³)/(4m)
that's it.
