So in this case first add all the cost togather, 3.50+2.25+9.95=$15.7
then move the decimal left two times to make the 5% into decimal number, which is .50
and multiply it by the total cost $15.7 which is 15.7*.50=7.85.
hope you like my answer and rate it. thank you :)
3px = 2q(r-5x)
distribute
2qr - 10qx
3px = 2qr - 10qx
To solve for x
add 10qx to both sides
3px + 10qx = 2qr
factor out x
x(3p+10q) = 2qr
divide both sides by 3p+10q to isolate x
x = 2qr / <span>(3p+10q)
Hope this helps :)</span>
By looking at the graph, we can tell that the slope is rise / run = 2 / -2 = -1
Slope = -1
We can also see that the y intercept is -1 or in point form (0,-1) Look at the line, it crosses the y axis between 0 and -2 at -1.
In your case 85 has repeated 3 times 70 has repeated 2 times and 95 has repeated 3 times if you still don’t understand my number is 8177074197 I can try to help you a little more.
Answer:
AD = 230
Step-by-step explanation:
AD = 30x - 10
MN = 31x + 1
BC = 30x + 28
To find the length of AD, we need to generate an equation that will enable us to find the value of x.
Thus,
MN = ½(AD + BC) => Trapezoid Midsegment Theorem
Plug in the values
31x + 1 = ½(30x - 10 + 30x + 28)
(31x + 1) × 2 = 30x - 10 + 30x + 28
62x + 2 = 30x - 10 + 30x + 28
Add like terms
62x + 2 = 60x + 18
62x - 60x = -2 + 18
2x = 16
x = 16/2
x = 8
✅AD = 30x - 10
Plug in the value of x
AD = 30(8) - 10 = 230
