If you are going to eliminate the y term the y must be the same value but different signs
since the second equation has y, a value of 3 you mist make the first one -3 so you will multiply the whole equation by -3
c is the answer
Answer:
r≈3.95
Step-by-step explanation:
Using the formula
A=πr^2
Solving for r
r=A
π=49
π≈3.94933
Answer:
<u>After a 75% increase, it would become</u>
x + 75%x = x + 0.75x = x(1 + 0.75) = 1.75x
<u>After a 50% decrease, it would become</u>
1.75x - 50%(1.75x) = 1.75x - 0.5(1.75x) = 1.75x - 0.875x = 0.875x = 
Because is less than x, the new amount would be less than the original.
The equation that has the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p are as follows;
<h3>How to rewrite an equation? </h3>
2.3p – 10.1 = 6.5p – 4 – 0.01p
The equation that has the same solution as above can be found as follows;
2.3p – 10.1 = 6.5p – 4 – 0.01p
combine like terms
2.3p – 10.1 = 6.5p – 0.01p - 4
2.3p – 10.1 = 6.49p – 4
Multiply through by 100.
Therefore,
230p - 1010 = 649p - 400
