Answer:
A constant is a number that stays the same. A variable is number that doesn't remain the same.
Since the two equations equal y, set them equal to each other.
x-1=-2x+5
From there, solve for x.
First get x on one side, by using the addition property of equality.
x-1=-2x+5
3x-1=5
Isolate x by adding 1.
3x=6
Lastly get x all by itself by dividing each side by 3.
x=2
You can now substitute your x-value, 2, into one of the equations (or both, if you wish; either one will result in the same answer.)
y=x-1
y=2-1
y=1
OR
y=-2x+5
y=-2(2)+5
y=-4+5
y=1
Final answer:
x=2 and y=1

Answer: A, 3 B, 2 C, 6
Step-by-step explanation:
7: the answer is C because 3/4 divided by 2/3 equals 1 1/8 and C if you multiply 3/4 x 3/2 it equals 1 1/8
14: the answer is 18 because if you add all the numbers they picked you’ll get 6 then divide it by 1/3 you’ll get 18
Then the other 2 km not sure I’m sorry
1, 3 and 4.
1. 3,6>0,9
2. 3,6<4,725
3. 3,6>1,575
4. 3,6>0,54
