It takes a printer 2 1/2 min to print 24 black-and-white pages and 4 color pages. It takes the same printer 3 1/4 min to print 3

0 black-and-white pages and 6 color pages. Let b represent the time in minutes needed to print a black-and-white page and c represent the time in minutes needed to print a color page.The shown system represents the given problem.
24b+4c=2 1/2
30b+6c=31/4

Multiply the first equation by 1.5, to get:
(1.5)(24b + 4c) = 1.5(2.5)
36b + 6c = 3.75
Subtract the second equation from this:
6b = 1/2
b = 1/12
Substituting into the first equation:
24b + 4c = 2.5
24*(1/12) + 4c = 2.5
2 + 4c = 2.5
4c = 0.5
c = 1/8
Therefore, it takes 1/12 minute to print a black-and-white page, and 1/8 minute to print a colored page.

P - 5(p+4) = p - (8-p)
zhuklara [117]

Answer:

Simplifying 6p + 2(4 + -2p) = 3(p + 4) 6p + (4 * 2 + -2p * 2) = 3(p + 4) 6p + (8 + -4p) = 3(p + 4) ... Move all terms containing p to the left, all other terms to the right. ... When you enter an equation into the calculator, the calculator will begin by ... Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5).

A number d minus 2 is less than -1 as an inequality
GalinKa [24]

Answer:

(d-2) <-1

Step-by-step explanation:

The number be d. d minus 2 means (d-2).

(d-2) is less than -1.

It means,

(d-2) <-1

It is the required inequality.

So,

Adding 1 both sides.

d-2+1 <-1+1

d-1<0

or

d<1

Hence, this is the required solution.

Sophie is making a copy of an angle. The original angle will be labeled G and the new angle will be labeled B. She has just fini
mel-nik [20]

Answer:

The next step is;

Label the two intersection points

Step-by-step explanation:

To make a copy of an angle, the steps are;

1) Draw the rays of the original angle passing through the point B

2) Open the compass slightly and place the compass point on the vertices G where the two rays meet to draw an arc that intersect both rays

3) Label the point of intersection of both rays points C and D

4) With the compass still opened to the same width, move the compass to the point B on the line the angle is to be copied and draw a similar arc intersecting the ray at J

5) Open the compass to the width of C and D on the original angle and place the compass at point J to mark the arc on the copied angle location at M

6) Draw a line from B passing through M to complete the second ay of the copied angle.

Nicole and adam are each saving money for a car. the total amount of money nicole will save is represented by the function f (x)
Yakvenalex [24]
For this case we have the following functions:
 f (x) = 36 + 4x
 g (x) = x2 + 15
 By matching both functions we have:
 f (x) = g (x)
 36 + 4x = x2 + 15
 Rewriting we have:
 x2 + 15 - 4x - 36 = 0
 x2 - 4x - 21 = 0
 Solving the polynomial we have:
 (x-7) (x + 3) = 0
 x = -3
 x = 7
 Taking the positive root we have:
 x = 7
 Answer:
 
They will have the same amount of money saved after:
 
x = 7 weeks
