Hey there!
In order to solve this equation for y, you need to use addition, subtraction, and division to combine and simplify the terms. You do this by first eliminating the terms, which you do by completing whatever will make each term equal to zero. Then, you'll repeat this same thing on the other side of the equation, like so:
<span>5y + 3 = 2y – 3x + 5
– 3 – 3
</span>
5y = 2y – 3x + 2
As you can see, I subtracted three from +3 the left side to cancel it out, then repeated that on the right side to the similar term (the constant). Now, just repeat that with your other terms until your equation is equal to y.
5y = 2y – 3x + 2
+ 2y + 2y
<u>7y</u> = <u>–3x + 2</u>
7 7
y = <u>–3x + 2</u>
7
When you can't simplify any more, you have your answer. y will be equal to –3x + 2 over 7.
Hope this helped you out! :-)
5x=35
x=35/5 (/=divided)
x= 7
so you divide 5x by 5 to cancel out that 5 and then since you did it to that side you have to do it to the other side so you divide 35 by 5 and that equals 7 so you’re left with x=7
Answer:
correct option is D. 630 kcals
Step-by-step explanation:
given data
Ashley weight = 130 lb
exercise time = 48 minutes
VO2 = 2.72 LO2/min
VCO2 = 2.24 LCO2/min
to find out
total energy expenditure
solution
first we get here respiratory exchange ratio that is
respiratory exchange ratio (RER) = 
...........1
RER = 
RER = 0.823
now we get here calorific value that is
calorific value = 3.815 + 1.23 × RER
calorific value = 3.815 + 1.23 × 0.823
calorific value = 4.827 kcal/L O2
so now we get energy expended that is
energy expended = VO2 × calorific value × time
energy expended = 2.72 × 4.827 × 48
energy expended = 630 kcals
so correct option is D. 630 kcals
