Hi!
I'm not sure how to slove this, but I do know how to solve it ;D
<h3>We can't know the exact value of y, but we can isolate y on one side. First, multiply by z on both sides. </h3>

x + y = 3 * z
<h3>Now subtract x from both sides.</h3>
x - x + y = 3 * z - x
<u>y = 3 * z - x</u>
<h2>The answer is y = 3 * z - x</h2>
Hope this helps! :)

The correct question is
The local currency it gives is a total of 275 Yuan. <span>If the yuan is worth 6.58 to a US$, what would the price to a US$ be if the yuan changed to 6.25
The </span><span>options are A)$2.21 B)$2.50 C)$13.31 D)$41.79 E)$44.00
we know that
</span><span>at the current exchange rate give (6.58)
</span>if 1 usd-----------------> 6.58 yuan
X usd------------------> 275 yuan
X=275/6.58------------> X=41.79 usd
at the current exchange rate give (6.25)
if 1 usd-----------------> 6.25 yuan
X usd------------------> 275 yuan
X=275/6.25------------> X=44 usd
so
the change in price in US$ would be [44-41.79]=US$2.21
the answer is the option
A)$2.21
4x+4 you have to distribute it
Rewritten: y=15x + 50
slope: 15
y intercept: (0,50)
Answer:
400
Step-by-step explanation:
52 divided by 13 =4
4x100=400
