If s is the Riley`s sister`s age and Riley is 3 years older so Riley`s age is:
s/3 so the sum of their ages is:
s + s/3 = 4s/3 :)))
i hope this is helpful
have a nice day

Answer:
The weight of the object is 3 kg.
Step-by-step explanation:
<u>Step 1:
</u>
Let object weight be x kg.
Now, as per the available data,
3/4 kg + 3/4 (x kg) = x kg
<u>Step 2:
</u>
3/4 (1 + x) = x
1 + x = 4x/3
1 = x (4/3 - 1)
x = 1 / (1/3)
x = 3
Weight of Object is 3 kg.
<u>Step 3:
</u>
Let's check if this value satisfies the first equation.
3/4 + 3/4 x 3 = 3/4 + 9/4 = 12/4 = 3
Hence proved.
Answer:
y=(-6/5)x+8.6
Step-by-step explanation:
If a line is perpendicular to 5x-6y=9, then it must have a slope that is the negative reciprocal.
1) Fine the slope of the first line by setting the equation equal to y.
5x-6y=9
5x-9= 6y
(5/6)x-1.5=y
slope= 5/6
2) Find the negative reciprocal of the slope
slope: 5/6
reciprocal: 6/5
negative reciprocal: -6/5
3) We now get to use the points (-3, 5) by plugging them into slope-intercept form. The goal is finding the y-intercept.
y=mx+b
5=(-6/5)(-3)+b
5=(-18/5)+b
5= -3.6+b
b= 8.6
4) Now we put everything back in slope-intercept form.
y=(-6/5)x+8.6
