Answer:
15y
Step-by-step explanation:
8y + 7y
first, we add the numbers which is 8+7 = 15
now we add the ys that = y+y= y ( when you add any alphabet letter the answer will be itself .)
then we add 15 + y but we can not add these but we can write it as 15y
= 15y
have a wonderful day
Answer:
27 and 23
Step-by-step explanation:
We can solve this problem as a system of equations. X is the first number and Y is the second number.
The first equation is x+y = 50 and the second equation is x-y=4
Now we solve the system, using elimination method:
x+y=50
x-y=4
2x = 54
x = 54/2
x = 27
And from any of the equations we can find Y
27 + y = 50
y = 50 - 27
y = 23
The open circle means the inequality will be greater than or equal to (≥) or less than or equal to (≤).
A closed circle means the inequality will be greater than (>) or less than (<)
An arrow pointing right to increasingly positive values means the inequality is getting greater (> or ≥)
A narrowing pointing left to increasingly negative values means the inequality is getting lesser (< or ≤)
So for this graph with an open circle and rightward pointing arrow, “x” will be some number on the number line greater than the first point of -38:
x > -38
Well i got 130.
hope it helps : )
Answer:
Yes
Step-by-step explanation:
We can use the Pythagorean Theorem to check if this triangle is a right triangle:

Note that
and
are the legs of the triangle and
is the hypotenuse:
Substitute the lengths of the sides into the equation:


Therefore this triangle is a right triangle.
