Adam saved 35% of the of the 400 dollar he needs to save to buy a bike. How much money has Adam saved so far?

Answers

First write the relationship in words: "What number is 35% of 400?" 

Then write an equation to represent this relationship: x = 35\% * 400 or, written another way x = 0.35*400

And then solve:
x=0.35*400=140

Then answer the question: "Adam has saved $140."  

Does the point (25,75) lie on the straight line y=3x. How do you know that

Answers

"Yes" the point (25, 75) lie on the straight line y=3x

The equation f of straight line is y = mx + c

where m is slope of line and c is intercept

Given straight equation is

y = 3x.....(1)

If we compare this equation with straight line equation. we get,

m = 3 and 0 is intercept,

Given point are (25, 75).

put these given point in equation (1)

75 = 3 (25).

75 = 75.

Therefore, the given statement is true.

What minus 3/10 equals 1/5

Answers

3/10 minus 1/5 equals 1/10

(3/10) - (1/5) = (1/10)

Explanation:

Make sure both fractions have the same denominator. 1/5 would turn into 2/10, and 3/10 would stay the same. When the denominators are equal, subtract the numerators to get the answer.

1/5 = 2/10

(3/10) - (2/10) = (1/10)
