Convert 10x + 2y = 30 to slope intercept form by solving for y.
Your answer
Send me a copy of my responses.
Answer:
y = -5x + 15
Step-by-step explanation:
10x + 2y = 30
Subtract 10x from both sides.
2y = -10x + 30
Divide both sides by 2.
y = -5x + 15
Twenty-four percent of the 25 swim team members are new on the team. How many members are new?
A. 24
B. 85
C. 106

emma's mother started a college fund of emma's 3rd birthday. She deposited $4,500 into an investment account that yields an interest rate of 7.5% compounded annually. If no additional deposits or withdrawals are made, how much will this investment account be worth when emma turns 18 years old?
Answer:
The interest is $1350 and the amount is $5850.
Step-by-step explanation:
STEP 1: Find an interest by using the formula I = P*I*T, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this example P = $4500, i = 7.5% and t = 4 years, so
4500*0.075*4
I = 1350
STEP 2: Find an amount by using the formula .
Since P = $4500 and I = $1350 we have
$4500 + $1350 = $5850

JKLM is a rhombus. KM is 20 and JL is 48. Find the perimeter of the
rhombus.
Answer:
104 units
Step-by-step explanation:
Given
Shape: Rhombus
[tex]JL = 48[/tex]
[tex]KM = 20[/tex]
Required
Determine the perimeter
The given parameter are the diagonals of the rhombus.
The perimeter (from diagonals) is calculated as thus:
[tex]P = 2\sqrt{(JL)^2 + (KM)^2}[/tex]
Substitute values for JL and KM
[tex]P = 2\sqrt{48^2 + 20^2}[/tex]
[tex]P = 2\sqrt{2304 +400}[/tex]
[tex]P = 2\sqrt{2704}[/tex]
[tex]P = 2 * 52[/tex]
[tex]P = 104[/tex]
Hence, the perimeter is 104 units

Lainey puts $600 into a GIC for 5 years. The GIC pays 6.2% interest, compounded monthly. How much interest has she earned after 5 years?
Answer:
FV= $819.03
Step-by-step explanation:
Giving the following information:
Initial investment= $600
Number of periods= 5*12= 60 months
Interest rate= 0.062/12= 0.0052
To calculate the future value of the investment, we need to use the following formula:
FV= PV*(1+i)^n
FV= 600*(1.0052^60)
FV= $819.03
Haley bought 8 pencils and 3 folders for $10.39. Nicole bought 5 pencils and 4 folders for $10.51. How much does a folder cost?
Answer:
$1.89
Step-by-step explanation:
1) 8p+3f=$10.39
2) 5p+4f=$10.51
where p represents pencil & f represents folder.
multiply the first equation by 5 and the second equation by 8.
40p+15f=$51.95
40p+32f=$84.08
Subtract
17f=$32.13
f=$32.13/17 =$1.89
Answer:
$1.89

(2x + 8)°
120°
5y
Answer: y = 2x + 3. 4x - 3y = 2. (A.K.A 6)
Step-by-step explanation: What is the value of the x-coordinate of the point of ... We can solve the system of equations by substituting the value of y from the second equation into the first. y = 2x + ... Thus, the second and third lines intersect at (-11/2,-8). ... 6y - 3x = -6: 4x - 5y + (6y - 3x) = 12 + (-6). 4x - 3x + 6y - 5y = 12 - 6. x + y = 6.

Which is the greatest common factor of 18 and 54?
Answer:
18
Step-by-step explanation:
18 can be divided by 18 =1
54 divided by 18 = 3
The greatest common factor of numbers 18 and 54 is,
⇒ GCD = 18
What is Greatest common factors?The highest number that divides exactly into two more numbers, is called Greatest common factors.
We have to given that;
To find the greatest common factor of 18 and 54.
Now, We know that;
Greatest common factor of numbers are that highest number which divides exactly into two more numbers,
Here, The numbers are,
⇒ 18 , 54
⇒ 18 = 18
⇒ 54 = 18 × 3

5x + 100 = 2100
5x = 2000 (subtarct 100 from both sides)
x = 400 (Divide 5 from both sides)
x = 400
Answer:
x=400
5x+100=2100

C)125.55square cm
Step-by-step explanation:
AB is a line is symmetry
Total length of left half part=12cm+9cm+3cm+5cm
Total length of left half part=29 cm
Length of left half part=Length of right half part
Therefore, length of right half part=29 cm
A) Perimeter of the shape=29cm+29cm=58cm
B)
Pythagoras theorem
[tex](Hypotenuse)^2=(Base)^2+(Perpendicular\;side)^2[/tex]
Hypotenuse=12 cm
Base=5+3=8cm
