Answer:

total balloons = 120r+72y

Step-by-step explanation:

If there are 120 cases of red balloons and r red balloons in each cases

Number of red balloons = 120*r

If there are 72 cases of yellow balloons and y yellow balloons in each cases

Number of yellow balloons = 72y

The total number of balloons is red balloons plus yellow balloons

total balloons = 120r+72y

Sign the following values a=5 b=10 c=15

a_sh-v [17]

Answer:

a=5,b=10,c=15

1)(a+b)-5(c+a)

=(5+10)-5(15+5)

=(15)-5(20)

=15-5(20)

=10(20)

=200

2)(10×15)10(5×2)

=150×10×10

=15000

3)(a-b)+(a+b)

(5-10)+(10+5)

(-5)+15

-5+15

=10

4)(2ab-45)+a

=(2×5×10-45)+5

=(100-45)+5

=55+5

=60

What is the value of x?

Dafna1 [17]

Answer:

Step-by-step explanation:

We use the concept of similarity to find the value of X.

Δ APR ≡ ΔCDR

∴ AR/CR = PR/DR

(10+x)/x = (15+42)/42

42(10+x) = 57x

420 + 42x = 57x

57x - 42x = 420

15x = 420

x = 420/15

= 28

The non separable differential equation dy dx = 8x − 2y has a linear particular solution of the form y = mx + b. Find m + b.

yulyashka [42]

Answer:

$m + b=2$

Step-by-step explanation:

From the question we are told that

The non separable differential equation $\frac{dy}{dx} = 8x - 2y$

Generally the chi form of a give equation is mathematically represented as

$\frac{dy}{dx} +P(x)y= q(x)$

$\frac{dy}{dx} + 2y = 8x$

$ye^2^x=\int e^2^.8xdxx$

$ye^2^x=8(\frac{xe^2^x}{2}-\frac{\int e^2^x}{2})$

$ye^2^x=8(\frac{xe^2^x}{2}-\frac{e^2^x}{1})+c\\$

$ye^2^x=4x^2^x-2e^2^x+c$

$y=4x-2+c$

for c=0

$y=4x-2$

Therefore

$m=4\\b=-2\\m + b=4-(+2)$

$m + b=2$
