Answer:

There is no x to solve, so I will solve for y.

y=-1.8

What I did was simplify and get the term one side.

Answer:

y = -1.8

Step-by-step explanation:

0.6+(0.5y-1)=y+0.5

the parenthesis can be remove because there is no multiplication

0.6 + 0.5y - 1 = y + 0.5

now combine numbers

0.6 - 1 + 0.5y = y + 0.5

-0.4 + 0.5y = y + 0.5

subtract 0.5 from both sides

-0.4 - 0.5 + 0.5y = y

-0.9 + 0.5y = y

now subtract 0.5y from both sides

-0.9 = 1y - 0.5y

-0.9 = 0.5y

now divide both sides by 0.5 and switch

y = -1.8

A coffee supply store waits until the orders for its special coffee blend reach 100 pounds before making up a batch. Coffee sell
Daniel [21]
Let x represent the number of pounds of $10.75/lb coffee used in the mix.
.. 10.75x +3.25(100 -x) = 5.65*100 . . . . . . total cost of coffee blend
.. x(10.75 -3.25) = 100*(5.65 -3.25) . . . . . .separate x-terms from non-x terms
.. x = 240/7.5 = 32

32 pounds of $10.75/lb coffee should be used
68 pounds of $3.25/lb coffee should be used

Which statement is true about the equation 3/4 z - 1/4 z + 1 = 2/4 z + 1?
Verizon [17]

Answer:

D, infinitely many solutions

Step-by-step explanation:

Let's first simplify the left side:

3/4 z - 1/4 z + 1 = 2/4 z + 1

Clearly, once you simplify the left side, it's the exact same as the right side. This is a true equation: 2/4 z + 1 = 2/4 z + 1

For any value that you put in for z, it will always be equal, no matter what.

Thus, the equation has D, infinitely many solutions.

Hope this helps!

Walter's savings account has a balance of $273. After 5 years, what will the amount of interest be at 5% compounded quarterly?
rodikova [14]
Given:
Principal = $273
Interest rate = 5% compounded quarterly
time = 5 years

A = P (1 + r/n)^nt

A = amount of money accumulated plus interest
P = principal
r = interest rate (in decimal form)
n = number of times the interest is compounded per year
t = total number of years the amount is deposited

A = $273 (1 + 0.05/4)⁴*⁵
A = $273 (1 + 0.0125)²⁰
A = $273 (1.0125)²⁰
A = $273 * 1.2820
A = $349.99

$349.99 - 273 = $76.99

The compounded interest amounts to $76.99
