Answer:90
Step-by-step explanation:
10,20,30,40,50,60,70,80,90,100
Counting in tens the same row as 83 is 90 .
According to the properties of inequality, we reverse the inequality symbol when we add or multiply by any negative number
Given inequality is Ax + B > C
In the first step, we subtract B from both sides
Ax + B > C
Ax + B - B > C - B
Ax > C - B
Now to remove A we divide by A on both sides
If A is negative then the reverse the inequality sign
When A is negative then > symbol becomes < symbol
so the inequality symbol be reversed when the value of A is negative
Answer:
40.99* 2.1= 86.079
Step-by-step explanation:
Let n be the amount of 80% solution; and 150-n be the amount of 20% solution. Then:
.8n+.2(150-n)=.6(150)
.8n+30-.2n=90
.6n=60
n=100
150-n=50

Answer:
b
Step-by-step explanation:
In y=mx+b form, the b is the y-intercept, therefore where the line crosses the y-axis on the graph. In this graph, the line crosses the y-axis at 100. This means that the "b" value is 100. So far, our equation is y=mx+100.
Next, to find m, you go to any other point on the graph and see how much units (rise over run) you went to get there. I picked the point (2,150), You can see that it took me 1 unit up and 2 units to the right to get to that point, leading us to believe the slope is 1/2.
Finally, put everything together and you get the answer of y=1/2x+100 (the letters do not matter) :)
