You bought a magazine for $5 and four erasers. you spent a total of $25.
Magazine cost: 5$ each
Eraser cost: X$ each
Total cost is the number of items (1 magazine) times the cost of each item (5$). We don't know the cost of each eraser, so we represent that using a variable, X.
1(5) + 4(X) = 25
5 + 4X = 25
subtract 5 from both sides
4X = 25 - 5
4X = 20
divide both sides by 4
X = 20/4
X = 5
Each eraser cost 5$
Answer:
5
Step-by-step explanation:
a minus times by another minus makes a positive, so it is basically 1 x 5
Answer is 199 because it adds up by 8 after 12 at the beggining
The equation of line that passes through the points (-3,-1) and
(-6,3) is:
Step-by-step explanation:
Given points are:
(-3,-1) =(x1,y1)
(-6,3)=(x2,y2)
The slope-intercept form of equation of line is:
We have to find the slope first
Putting the value of slope in the slope intercept form
To find the value of b, putting the point (-3,-1) in the equation
Putting the values of b and m

Answer:
The price was reduced by about 53%
Step-by-step explanation:
Per cent of change = (amount of change) ÷ (original amount)
% change = (799.99 - 375.99)/799.99
= 424 / 799
= .5300
= 53 %
