25% of what number is 13
2 answers:
Answer: x = 52
Step-by-step explanation: Well <em>percent</em> means <em>over 100</em> so we know that 25% means 25/100. <em>Of</em> means <em>times</em>, <em>what number</em> means <em>x</em>, <em>is</em> means<em> equals</em>, and <em>12</em> means <em>12</em>. So we can translate this problem into an equation.
So we have the equation 25/100 · X = 13
Notice that 25/100 can be reduced to 1/4.
So rewriting our problem we have X/4 = 13.
To get rid of the fraction, we multiply both sides of the equation by 4 and we have <em>x = 52</em>.
This means that 25% of <em>52</em><em> </em>is 13.

Answer:
Step-by-step explanation:
The first step will be to make y the subject of the formula, by multiplying both sides of the equation by -1.
y = x - 1
This is simply the equation of a line with a slope of 1 and y-intercept (0,-1)
To determine the three points that solve the equation, we can let x be;
0, 1, 2
When x =0, y = 0-1 = -1
When x = 1, y = 1-1 = 0
When x = 2, y = 2 - 1 = 1
Therefore, we have the following three sets of points that can be used to graph the given linear equation;
(0, -1)
(1, 0)
(2, 1)
