Answer:

1 a.   $132= 9a + 6c

1b.  8 adults

2a. 152= 4b + 3v

2b. 32 students per bus

Step-by-step explanation:

1b. 132= 9a +60,  so 132 subract 60 = 72, then divide by 9, so 72/9= 8 adults

2b. 152=4b + 24, so 152 subract 24 =128, then divide by 4, 128/4= 32 students per bus

I need to know quick so i would rly apriciate help, if you do a answer and the work ill give u a brainliest!!!
inn [45]

Answer:

6

Step-by-step explanation:

Let the two integers be a and b.

The difference of them is 26. Thus:

a-b=26

One of them (let's use a) is 2 more than 5 times the other. Thus:

a=2+5b

Substitute:

a-b=26\\(2+5b)-b=26

Combine like terms:

4b+2=26

Subtract 2 from both sides:

4b=24

Divide by 4:

b=6

And the second number is:

a-b=26\\a-6=26

Add 6 to both sides:

a=32

So, our two numbers are 32 and 6

And the smaller integer is 6.

And we're done :)

The diameter of a circle if five times the length of a recatngle. The length of a rectangle is three times the width of the rect
Leno4ka [110]

Answer:

706.5 ft²

Step-by-step explanation:

A. Width of the rectangle

The formula for the area of a rectangle is

A = lw

But, l = 3w, so,

A = (3w)w

= 3w² = 12

      w² = 4         Divided each side by 3

      w   = 2 ft     Took the square root of each side

B. Length of rectangle

l = 3w = 6 ft

C. Diameter of circle

d = 5l = 5 × 6 = 30 ft

D. Radius of circle

d = 2r

r = d/2     Divided each side by 2

r = 30/2 = 15 ft

E. Area of circle

A = πr² = 3.14 × 15² = 3.14 × 225 = 706.5 ft²

The area of the circle is 706.5 ft².

What is a equation that has a zero of -2 with a multiplicity of 3, a zero of 1 with a multiplicity of 1, degree of 4, and rises
zloy xaker [14]

Answer:

x^4+8x^3+18x-27=0

Step-by-step explanation:

In a equation of the form

(x-a)^n(x-b)^m=0

you have roots in x=a and x=b, and multiplicity of n and m respectively.

Hence, the equation is

(x-(-2))^3(x-1)=0\\(x+2)^3(x-1)=0\\

by expanding the factors you have

(x^3+3x^2(3)+3x(3)^2+(3)^3)(x-1)=0\\(x^3+9x^2+27x+27)(x-1)=0\\x^4+9x^3+27x^2+27x-x^3-9x^2-27x-27=0\\x^4+8x^3+18x^2-27=0

HOPE THIS HELPS!!
