Which would be the first step for solving the equation x + 2 = 18?
A. add - 2 to both sides of the equation
B. add 18 to both sides of the equation
c.
divide both sides of the equation by
7
16
D
multiply both sides of the equation by
7
Answer:
A. Add -2 to both sides
Step-by-step explanation:
The reason you need to add -2 to both sides is because if you add -2 to -2 it cancels out and you are left with x=18. But you need to add -2 to 18 too because them the equation won't be equal anymore.
How many roots does y=3x^2+8 have?
Answer:
This quadratic has two unequal, imaginary roots.
Step-by-step explanation:
y = 3x^2 + 8 is a quadratic function, and (like all quadratics) it has two roots. In this case they happen to be different (unequal), as well as imaginary.
Setting y = 3x^2 + 8 = 0, we get:
3x^2 = -8, or
x^2 = -8/3
Taking the square root of both sides, we get
x = ±i√(8/3) (2 imaginary roots)
Nikki has $10 to buy snacks. She buys 2 candy bars that are $0.79 each, and she buys a pa
cookies that cost $3.89. How much did she spend in all on snacks?
Answer:
$5.47
Step-by-step explanation:
You multiply 2 by 0.79. Then you add that result (1.58) to 3.89 and you get your answer.
A hot air balloon went from an elevation of 5,717 feet to an elevation of 3,388
feet in 34 minutes. What was its rate of descent?
The rate of the descent was
feet per minute.
Answer:
68.5 feet per minute
Step-by-step explanation:
rate of descent = feet / minute
First you need to find how many feet it has descended:
beginning altitude- ending altitude = total feet descended
5717 feet - 3388 feet = 2329 feet
To figure out the rate of decent we will divide
2329 feet / 34 minutes = 68.5 feet per minute
The hot air ballon descended 68.5 feet per minute for 34 minutes.
What expression represents the area of the triangle?
A triangle has a base of 24 and a height of 10. Another side has a length of 26.
One-half times 10 times 24
One-half times 10 times 26
One-half times 24 times 26
One-half times 10 times 24 times 26
Given:
Base of the triangle = 24
Height of the triangle = 10
Another side of the triangle = 26
To find:
The area of the expression of the area of the triangle.
Solution:
We know that, the area of a triangle is
[tex]Area=\dfrac{1}{2}\times base\times height[/tex]
Putting base = 24 and height = 10, we get
[tex]Area=\dfrac{1}{2}\times 24\times 10[/tex]
It can be written as
[tex]Area=\dfrac{1}{2}\times 10\times 24[/tex]
Therefore, the correct option is A.
Answer:
The correct answer is A.
One-half times 10 times 24

6. Three consecutive integers add up to 51. What are these integers?
Answer: 16,17,18
Step-by-step explanation:
(x)+(x+1)+(x+2) = 51
x+x+x+1+2=51
3x+3=51
3x=51-3
3x=48
x=16
x+1 = 17
x+2= 18

find the solution to the system of equations
Answer:
(-3, -4)
Step-by-step explanation:
y= -4
so you plus y in for the y=2x+2 equation where you get x=-3
[tex]\huge\text{Hey there!}[/tex]
[tex]\large\text{If y = -4 then SUBSTITUTE it into the EQUATION}[/tex]
[tex]\large\text{-4 = 2x + 2}[/tex]

How would I find the values of x, y and z?
Answer:
x = 3.38
y = 9.24
z = 8
Step-by-step explanation:
first: solve for the vertical length
8√2² = 2z²
128 = 2z²
z² = 64
z = 8
vertical height = 8 also because z is one side of a square
tan 60 = z/a = 8/a
a = 4.62
x = 8 - 4.62 = 3.38
sin 60 = z/y = 8/y
y = 9.24
