Answer:
x = 4
y = 1
Step-by-step explanation:
Here, we want to solve the system of equation using elimination method
We have this as follows;
3x + y = 13
4x- 3y = 13
Multiply equation 1 by 3
9x + 3y = 39
4x-3y = 13
Add the two equations
13x = 52
x = 52/13
x = 4
From equation 1;
3x + y = 13
y = 13-3x
y = 13-3(4)
y = 13-12 = 1
Answer:
no she cant she can fit 20 of them
Step-by-step explanation:
Y=-x+8
gradient of the parallel line is the same as the gradient of the line given, which is -1
to find the y-intercept, sub the values (9,-1) into the equation we are finding which is y=-x+c
Is this suppose to be an equation or is there something missing here?
Answer: 12,8 approximately 13 cones
Step-by-step explanation:
1] volume of a cone
V=1/3πr^2h
V=1/3π(3)^2(5)
V=47,12 cubic inches
2] volume of a cylinder
V=πr^2h
V=π(8)^2(3)
V=603.19
Now devide the volume of a cylinder by the volume of a cone
603,19÷47,12=12,8 cones
