Answer:
Arrange the following number in descendig otder
1.25 divided by 3/4, convert to decimals. 1.25/0.75 ≈ 0.66
Answer:
x = 0
y = 2
Step-by-step explanation:
3x + 9y = 18 ---------eqn 1
y = x + 2---------eqn 2
Substitute eqn 2 into eqn 1, for the value of y
3x + 9( x + 2) = 18
3x + 9x + 18 = 18
12x + 18 = 18
12x = 18 -18
12x = 0
Divide both sides by 12 , to get the value of x.
12x/ 12 = 0/12
x = 0
Substitute x = 0 into eqn 2
y = x + 2
y = 0 +2
y = 2
Hint: to confirm the values
x = 0
y = 2
Let's take eqn 1 ,
3x + 9y = 18
3(0) + 9(2)
= 0 + 18
= 18
Correct
Let's take eqn 2
y = x + 2
Let's find y
y = 0 + 2
y = 2
Correct too
Its a trick question. Its just 235 + 123 = 358. Find 358 on the number line and place a dot there, boom you did it on a number line.
Answer:
Step-by-step explanation:
(x + 2)/2 = 0
x + 2 = 0
x = -2
(y + 5)/2= 2
y + 5 = 4
y = -1
(-2, -1) the other endpoint
