Answer:
Hi there the answer will be (3,11)
Since you are using the substitution way, you first plug in one of the y's into the other equation and you can see that they are set equal to each other.
2x+5=3x+2
Then you subtract 2x on both sides to get the x's on the same side
and you get 5=x+2
Then you subtract 2 on both sides, and you get x to equal to 3
then you plug x into any equation to get y to equal 11
y= 2(3)+5
Answer:
11, 12, 13
Step-by-step explanation:
x is the first number
(x + 1) is the second number
(x + 2) is the third number
x + x+1 + x+2 = 36
3x + 3 = 36
3x = 36 - 3
3x = 33
x = 11 ← the first number
the second number = x + 1 = 11 + 1 = 12
the third number = x + 2 = 11 + 2 = 13
It take 23 mins for the drive
He needs to reach the airport by a quarter before 6
a quarter before 6 = 5.45
So he needs to leave 23 mins before 5.45
23 mins before 5.45 = 5.22
Answer:
width= 75 cm
Step-by-step explanation:
We need to recall the formula to calculate the area of a rectangle, since we are dealing with a rectangular window:
Area of rectangle = width * length
therefore, since they give us the window's area: 6525 
, and also the window's length: 87 cm, we just need to replace those values in the area formula and solve for the unknown "width". We do such by dividing both sides of the equation by 87 cm in order to isolate the unknown on one side of the equal sign;
Answer:
x=52°
Step-by-step explanation:
38° +90°+x = 180° ( Angles on a straight line)
x+ 128° =180°
x= 180° -128°
x= 52°
