You would do 30×10 which equals 300. The answer is 300.
I hope this helps you
2x-3=x+2
X=5
HG=11x+5=11.5+5=60
JI=60/2=30
Answer:
Step-by-step explanation:
Rise over run. Difference in y values is rise. 4.25 -6 is -1.75. Run s difference in x values. 12.5 -7 is 5. Divide -1.75/5 to get -0.35 As a faction thats -7/20
A. (2,6)(5,0)
slope = (0 - 6) / (5 - 2) = -6/3 = -2
y = mx + b
slope(m) = -2
(2,6)..x = 2 and y = 6
sub and find b, the y int
6 = -2(2) + b
6 = -4 + b
6 + 4 = b
10 = b
so line A , equation is : y = -2x + 10
============================
B. (0,2)(6,6)
slope = (6 - 2) / (6 - 0) = 4/6 which reduces to 2/3
y = mx + b
slope(m) = 2/3
(0,2)...x = 0 and y = 2
sub and find b, the y int
2 = 2/3(0) + b
2 = b
LIne B, equation is : y = 2/3x + 2
=========================
so we have :
y = 2/3x + 2
y = -2x + 10
2/3x + 2 = -2x + 10 ..multiply by 3
2x + 6 = -6x + 30
2x + 6x = 30 - 6
8x = 24
x = 24/8
x = 3
y = -2x + 10
y = -2(3) + 10
y = -6 + 10
y = 4
solution is (3,4).....3/4 is the solution to both lines <===
Hello!
We know that the length of the pack is 8 cm, width is 2 cm, and the volume is 48 cm^3.
The formula for volume is:
V = l × w × h
We don't want to find the volume...we already have that!
But we can use the volume and the length and width to find the height.
Since we multiply the dimensions to find the volume, we'll have to do the opposite to find a dimension.
And what's the opposite of multiplication? Division!
H = V ÷ lw
Multiply the length by the width, then divide the volume by that.
H = 48 ÷ 8(2)
H = 48 ÷ 16
H = 3
We can double check by using this to find the volume.
V = 8 × 2 × 3
V = 48
This means we're right!
