Answer:
x=1
y= -1
z=2
Step-by-step explanation:
x+y+z=2 and x-y-2z=6
if z=2 then
x+y+2=2 and x-y+4=6
and these become
x+y=0 and x-y=2
usign linear cancellation method we get
2x=2
dividing both sides by 2 we get
x=1
then going back to one of the original equations and plugging x=1 and z=2 we get
1+y+2=2
solving for y we get
y= -1
Answer:
x=0
Step-by-step explanation:
If x is 0, then 2x becomes 0. (2.5)^0 would then be 1. 4*1 would give 0 so x=0.
Answer:
= 12
Step-by-step explanation:
area of a rectangle = width x length
Given:
- area = 44 m²
- width = 3 2/3 m
- length = m
Substitute given values:
area of a rectangle = width x length
⇒ 44 = 3 2/3 x
⇒ = 44 ÷ 3 2/3
⇒ = 12
Answer:
$85 is your answer
Step-by-step explanation:
add both the 80 and 90
80+90=170
then divide by 2
170/2=85
Answer:
9/16
Step-by-step explanation:
3/8 ÷ 2/3
Copy dot flip
3/8 * 3/2
Multiply the numerators
3*3=9
Multiply the denominators
8*2 = 16
Numerator over denominator
9/16
