Solve the PROPORTION
3/4 = 1/2y
y=
Answer:
y=1 1/2 (fraction)
or
y=1.5 (decimal)
Step-by-step explanation:
We want to get y alone, so we need to get rid of the 1/2 in front of it. To do that we can multiply each side by 2 since 1/2 + 1/2 = 1.
3/4= 1/2y
multiply each side by 2
To multiply 3/4 by 2 you need to multiply the numerators and then multiply the denominators
2•3=6 & 4 • 1 =4
6/4
simplify
y=1 1/2
(If you need it in decimal form it would be y=1.5)

The product of 15 and a number X is -75. Write the equation, and solution for X.
Answer: [tex]x = -5[/tex]
Step-by-step explanation:
If a product of 15 and an unknown number equals -75 the equation should look like this:
[tex]15x = -75[/tex]
Now to solve for x:
1. [tex]\frac{15x}{15} = \frac{-75}{15}[/tex]
2. [tex]x = -5[/tex]
The solution for x is -5.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation. Equal treatment should be given to each party.
Given:
The product of 15 and a number X is -75.
So, the expression is
15x = -75
Now, divide 15 on both side
15x/15= -75/15
x= -5
Hence, the value of x is -5.

Jason invests money in an account paying simple interest. He invests $160 and no money is added or removed from the investment. After one year, he has $164.80. What is the simple percent interest per year?
Answer:
The answer is 3%
Step-by-step explanation:
1.) $160 divided by $164.80 = 1.03
2.) 1.03 x 100 = 103
3.) 103 - 100 = 3
4.) 164.80 - 160 = 4.80
5.) 4.80 divided by 160 = 0.03
6.) 0.03 x 100 = 3%

A fundraising organization will donate $250 plus half of the money it raises from a charity event.
What is the independent Variable?
What is the dependent Variable?
What is the domain?
What is the range?
Answer:
Independent Variable, Domain = Charity amount
Dependent Variable, Range = Donation amount
Step-by-step explanation:
Independent Variable is the causal variable. Dependent variable is the resultant or effected variable.
In this case, organisation donates money, a constant value (250) & a proportion (half) of charity. So, independent variable (causal) is charity, effecting the dependent variable ie donation.
Equation : Let donation = d, charity = c. Given : d = f (c) , where d = 250 + c/2
Domain is set of of all values for which a function is defined, range is the set of all values that f takes. So, domain is independent variable - charity & range is dependent variable - donation.

airplane a traveled 1273 miles in four hours.For airplane b y=621 x/2 represents rate of speed over the same four hours wichair plane traveled at a faster rate and by what factor?round to the nearest hundredth
Answer: Airplane A by a scale factor of 1.02
Step-by-step explanation:
Airplane A: 1273/4=318.25
Airplane B: Rate is the slope of equation, 621/2=310.5
So,
318.25/310.5=1.0249
Airplane 'a' is faster than airplane 'b' by a factor of 1.03 times.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, An airplane 'a' traveled 1273 miles in four hours.
∴ The airplane 'a' traveled (1273/4) = 318.25 miles per hour.
For airplane b y = (621x)/2 + 0b represents the rate of speed over the same four hours
∴ The rate of change per hour for airplane 'b' is (621/2) = 310.5 miles.
So, airplane 'b' is faster than airplane 'a' by a factor of (318/25/310.5) = 1.0257 = 1.03 times.
