Answer:
4:7
Step-by-step explanation:
3:5=6:10/2=3:5
9:15=9:15/3=3:5
Estimate
(x,y)
x=left right
y=up down
solution=intersection
looks like about 6.5 left or x=-6.5 and y=3.5 down or y=-3.5
(-6.5,-3.5) would be a good estimate
(if you did calculate it it would be (-32/5,-18/5) or about (-6.4,-3.6))
answer is first option
First convert the dimensions of the pyramid from feet to yards.
1 yard = 3 feet.
756 feet / 3 ft per yard = 252 yards.
480 feet / 3 ft per yard = 160 yards.
The formula for volume of a pyramid is: Area of the base x the height divided by 3.
Volume = 252 yds^2 x 160/3 = 63504 x 160/3 = 3,386,880 cubic yards.
Now to find the number of bricks needed. divide the total volume by the volume of 1 brick:
3,386,880 / 1.5 = 2,257,920 total bricks.
Answer:
x=14
Step-by-step explanation:
6(-6+x)=76-2x
Distribute
-36 +6x = 76 -2x
Add 2x to each side
-36+6x+2x = 76-2x+2x
-36 +8x = 76
Add 36 to each side
-36+36 +8x = 76+36
8x = 112
Divide by 8
8x/8 = 112/8
x=14
Answer:
a=1,b=3,c=10
Step-by-step explanation:
a= the number with the highest power, in this case it is x^2. Therefore, a=1.
b= the number with the second number, the one that has an x. Therefore, b=3.
c=the last number, the one with no variable. therefore, c=10
