4+4=8
i know this because i used a calculator i dont know math or what this means. have a good day!
Answer:
y = -3x - .25 or y = -3x + -.25
Step-by-step explanation:
y = slope (x) + y-intercept
-4 = -3(1.25)+b
-4 = -3 .75 + -.25
-4 = -4
Answer:
In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression; it is usually a number, but may be any expression.
Step-by-step explanation:
You can rewrite this problem into an equation. You know that the ratio of boys to girls is 4 to 3, which is the same as:
Cross multiply to get to 4G = 3B
Divide both sides by 4, to isolate the G (# of girls).
G = 3B / 4 = 0.75B
So you know that B + G = 35 (boys plus girls equals 35). Replace the G in this equation with the one you found above so that the entire equation only has one variable.
B + G = 35
B + 0.75B = 35
1.75B = 35
1.75B / 1.75 = 35 / 1.75
B = 20
However, you need to find G. So plug B back into one of the equations:
B + G = 35
20 + G = 35
G = 15
Inches can be measured with how long something is... Pounds can be measured with how much something weighs and cups with how much of something you need
