Good morning ☕️
______
Answer:
15
___________________
Step-by-step explanation:
f(x) = 5x + 40
then
f(-5) = 5(-5) + 40
= -25 + 40
= 40-25
= 15.
:)
20.70=3p+3
17.70=3p
$5.90=p
So if you only needed the equation to describe the word problem it is
$20.70=3p+3
If you want to know how much each pizza was it is $5.90; salad $3.00
That questions has to do with equivalent fractions, express a fraction in eights.
six and three quarters
= 6 3/4
<span>= 6 + 3/4
</span>= 24/4 + 3/4
= 27/4
and to convert that fraction to eights, just multiply numerator and denominator by 2:
= (27*2)/(4*2)
= 54/8
there are 54 eights in six and three quarters
Answer:
x=-1
y=-5
Step-by-step explanation:
(7x+y)-(x+y)=-6
6x=-6
x=-1
-1+y=-6
y=-5
Pythagoras theorem - The length of the third side is 6.71unit
What is Pythagoras theorem ?
The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a key relationship in Euclidean geometry between a right triangle's three sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
The Pythagoras theorem's equation is as follows:
H² = P² + B²
The triangle's third side will be the following length:
Let x represent the triangle's third side's length.
9² = 6² + x²
81 = 36 + x²
x² = 45
x = 6.708
x = 6.71 units
Hence, the third side of the triangle is 6.71unit
