The number is 6.25.
We will set up an equation for this. Let x be the unknown number. Subtracting 1.05 from it gives us
(x-1.05)
Multiplying the difference by 0.8 would give us
0.8(x-1.05)
Adding 2.84 to the product would give us
0.8(x-1.05)+2.84
Dividing the sum by 0.01 would give us
[0.8(x-1.05)+2.84]/0.01 = 700
We will start working backward, cancelling the division by 0.01 first by multiplying:
([0.8(x-1.05)+2.84]/0.01)*0.01 = 700*0.01
0.8(x-1.05)+2.84 =7
Subtract 2.84 from both sides:
0.8(x-1.05)+2.84-2.84 = 7-2.84
0.8(x-1.05) = 4.16
Use the distributive property on the left side:
0.8*x - 0.8*1.05 = 4.16
0.8x - 0.84 = 4.16
Add 0.84 to both sides:
0.8x - 0.84+0.84 = 4.16+0.84
0.8x = 5
Divide both sides by 0.8:
0.8x/0.8 = 5/0.8
x = 6.25

Answer:
Slope is 4 Y intercept is -5
Step-by-step explanation:
Y intercept is always the second number, and the slope is always with the x after. Also Y=MX+B
Answer:
3>b
Step-by-step explanation:
a+b>-4
a>-9
so a is greater than -9
so which means -7,-8,-6 is greater -9.
-7+b>-4
-7+4>-b
-3>-b
3>b
verification
a+b>-4
Substitute -7 for a
substitute 3 for b
-7+3>-4
the answer will be -4 which is correct.
