Answer:
Step-by-step explanation:
Let b represent the number of black
ink pens that John wants to buy.
Let r represent the number of red
ink pens that John wants to buy.
John wishes to buy 20 pens. This would be expressed as
b + r = 20
The store sells black ink pens for $5 and red ink pens for $4. John doesn’t wish to spend more than $92. The inequality to show this information would be expressed as
5b + 4r ≤ 92
Answer:
Rectangular Prism Surface Area Volume = lwh; Surface Area = 2(lw + lh + wh) Sphere Surface Area Volume = (4/3) π r 3; Surface Area = 4 π r 2; Spherical Cap Surface Area. Volume = (1/3) π h 2 (3R - h) Surface Area = 2 π Rh; Triangular Prism Surface Area Top Surface Area of a Triangular Prism Formula
Step-by-step explanation:
Find the volume by multiplying the width by the length by the hight. so 4 times 4 times 12. and you get 192 cubic inches.
Answer:
6days
total cost-$66
additional days-5
Step-by-step explanation:
41+5(x-1)=31+7(x-1)
41+5x-5=31+7x-7
36+5x=24+7x
12=2x
x=6
36+30=66
Answer:
Step-by-step explanation:
Two points are given to us and we need to find the slope of the line that passes through these two points . The two points are (-2,-3) and (5,4) .As we know that the slope of the line is given by 
<u>Slope </u><u>of </u><u>a </u><u>line </u><u>is </u><u>:</u><u>-</u>
On using this formula we can find the slope of the line .
<u>Putting</u><u> the</u><u> </u><u>respective</u><u> values</u><u> </u><u>:</u><u>-</u>
