Answer:
1,344
Step-by-step explanation: So first I multiplied 1,200 by .03 because in order to multiply by a percent you need to move it decimal back two times. After you multiply 1200 x .03 = 36. Next you would do 36 x 4 for the 4 years and it would = 144. Then you would add 144 to the original because it's interest and you would end up with Colin having 1,344.
If 5x + y = 20 and 10x - 2y = 50 are two linear equations in two variables. Find the value of x and y.
x = 1, y = 1
x = 2, y = 1/2
x = 9/2, y = -5/2
x = 1, y = 5/2
Answer:
x = 9/2, y = -5/2
Step-by-step explanation:
5x + y = 20
10x - 2y = 50
There's multiple ways to do this, but I will solve using substitution.
Isolate variable y on the first equation.
5x + y = 20
y = 20 - 5x
Substitute the value of y for 20 - 5x in the second equation.
10x - 2(20 - 5x) = 50
Use distributive property:
10x - 40 + 10x = 50
Combine like terms:
20x - 40 = 50
20x = 90
x = 90/20
x = 9/2
Substitute x for 9/2 and solve for y:
y = 20 - 5(9/2)
y = 20 - 45/2
y = 40/2 - 45/2
y = -5/2
Answer:
x =9/2, y = -5/2
Step-by-step explanation:
5(9/2) + -(5/2)= 20
45/2 + -5/2 = 20
40/2 = 20
10(9/2) - 2(-5/2) = 50
90/2 + 10/2 = 50
45 + 5 = 50

What's x?
Answer:
x = 166
Step-by-step explanation:
2 * 3 * 5 * 11 + (x * 2) =
6 * 5 * 11 + (x * 2) =
30 * 11 + (x * 2) =
330 + (x * 2) =
330 + (166 * 2) =
= 662
So, the answer is 166.

A movie theater sells morning tickets (m) for $4 and regular tickets (e) for $6. During one week, the theater earned $6000. The theater sold 890 more regular tickets than morning tickets.
Write a system of liner equation to represent this situation. (Solve by using Systems by Substitution)
Answer:
Step-by-step explanation:
Answer:
m = 66 & e = 956
Step-by-step explanation:
Create your equations:
$4m + $6e = $6000
m + 890 = e
Substitute/solve for morning tickets:
$4m + $6e = $6000 <-- m + 890 = e
$4m + $6(m + 890) = $6000
$4m + $6m + $5340 = $6000
$10m = $6000 - $5340
m = $660/$10
m = 66 morning tickets
Solve for Regular tickets:
m + 890 = e <--- m = 66
66 + 890 = 956
e = 956 regular tickets
Double check work:
$4m + $6e = $6000
$4(66) + $6(956) = $6000

What would y equal for this question
Answer:
12
Step-by-step explanation:
When looking at triangles it's always important to remember what the ratios are to parts of triangles. In the case of this triangle let's give the value 24 the variable of E. In every scenario in which Y is positioned above 24 or E, the answer is always E/2=y, or 24/2=y ---> 12.
y / 24 = 12 / 12 + 18
y / 24 = 12 / 30
y / 24 = 2 × 6 / 5 × 6
y / 24 = 2 / 5
y = 24 × 2 / 5
y = 48 / 5
y = 96 / 10
y = 9.6

write the following as
t = _____
p/q = q/t + 1
Answer:
t = 2q²/p
Step-by-step explanation:
subtract 1 from each side to get:
p/q - 1 = q/t
multiply each side by t/q to get:
(tp/q²) - 1 = 1
add 1 to each side to get:
tp/q² = 2
cross-multiply to get:
tp = 2q²
divide each side by p to get:
t = 2q²/p

Identify the following:
Domain
Range
Y-intercept
Step-by-step explanation:
F( x ) = 5 (3) ^ x
Y intercept
Let x = 0
f(0) = 5× 3 ^ 0
f(0 = 5 × 1
f(0) = 5
X intercept
let y = o
0 = 5 × 3 ^x
No x intercept/ zero

If f(x) = 3x2 – 4 and g(x) = 2x – 6, what is g(f(2))?
O-16
o -2
O 8
0 10
Answer:
The last option, 10 is correct
Step-by-step explanation:
f(x) = 3x^2 - 4
f(2) = 3(2)^2 - 4
f(2) = 12 - 4
f(2) = 8
g(x) = 2x - 6
g(8) = 2(8) - 6
g(8) = 16 - 6
g(8) = 10
This means that g(f(2)) is equal to 10

Lila is making 1/4 of a recipe for a bake sale. The original recipe calls for 2/3 cups of sugar. How much sugar does Lila need to
complete her recipe?
Answer:
Step-by-step explanation:
1/4 of 2/3 is just (1/4) / (2/3) or (1/4)(3/2)
1/4 * 3/2= 3/8
She needs to use 3/8 of a cup
The sugar needed by Lila to make 1 / 4 of a recipe is 1 / 6 of the total sugar needed to complete her recipe.
What is fraction?A fraction is a percentage of a whole. This entire sentence could be referring to a single location or a collection of locations. The English word "fraction" originates from the Latin word "fraction," which means "to break." As the first society to comprehend fractions, the Egyptians used fractions to solve a number of mathematical problems, including the distribution of food and resources and the absence of a metal currency.
Given:
The sugar quantity in the original recipe = 2 / 3
If Lila is making 1 / 4 of a recipe, so she needs 1/ 4 of the total sugar in the recipe,
The sugar needed by Lila = 1 / 4 of 2 / 3
The sugar needed by Lila = 1 / 4 × 2 / 3,
The sugar needed by Lila = 1 / 6 of the total sugar needed in the recipe.
Therefore, the sugar needed by Lila to make 1 / 4 of a recipe is 1 / 6 of the total sugar needed in the recipe.
