Answer:
The answer is D-16
Step-by-step explanation:
Since we have x on one side, and 49 degrees on the other, both angles are the same, so we subtract 1 from 49 to get 48, so that 3x has to equal 48. So we just divide 48 by 3 to get 16, so x = 16.

Solve the system by substitution. And show your work
-9y-10=x
5x+6y=-11
Answer:
x = -1, y = -1
( -1 , -1 )
Step-by-step explanation:
plug in -9y - 10 for x
5 ( -9y - 10) + 6y = -11
-45y - 50 + 6y = -11
-39y - 50 = -11
-39y = 39
y = -1
then plug in
-9(-1) - 10 = x
9 - 10 = x
x = -1

A painter used 1 1/2 gallons of paint to paint 3/4 of a room. At this same rate, how many gallons will it take to paint the whole room?
Please show your work with descriptions, this topic of math is really confusing for me.
Answer:
Convert to decimals:
1.5 and 0.75
Then, set up a proportion
1.5/0.75=x/1
proportion x/y=x/y
since the 3/4 and 1 are the same topic ( the room) we put them together.
Solve: 1.5/0.75=x
x=2
So 2 gallons

Answer:
The equation of the exponential function will be:
[tex]y\:=\:10\cdot \left(\frac{1}{5}\right)^x[/tex]Step-by-step explanation:
The general exponential function is defined as
y = abˣ
Here,
a is the initial value and b is the growth factorFrom the table, it is clear that the y-intercept is (0, 10). Note that the y-intercept can be determined by setting x=0 and solving for y.
here
at x=0, y=10
so a = 10
If we check the y-values, it is clear that every next value of y can be obtained by multiplying the previous y-value by 1/5.
In other words, the common multiplier = b = 1/5
Thus, the equation becomes
[tex]y\:=\:10\cdot \left(\frac{1}{5}\right)^x[/tex]
Thus, the equation of the exponential function will be:
[tex]y\:=\:10\cdot \left(\frac{1}{5}\right)^x[/tex]PLEASE HELP FAST! my two problems are in the photo.
Answer:
8.) x=115 degrees
9.) y=102 degrees
Step-by-step explanation:
8.) A triangles total degrees is 180, so 180-50=130. now the missing angles are congruent, so 130/2=65. and now we're working on the bottom right angle. which is 65. what we need can be added to the angle we just found to add up to 180, so reverse it. 180-65=115. so x=115 degrees.
9.) because y is congruent to the angle across from it, we can just assume y and 78 is equal to 180. 180-78=102. so y=102 degrees. Hope this helps!

B. 19,990,000 times
C. 200 times
D. 2 x 10^3 times
Answer:
Im not sure but i think its 200 times
Step-by-step explanation:
Russia is 2 × 10³ times larger than Puerto Rico.
What is Exponentiation?Exponentiation is a method of writing numbers, especially larger numbers, as the power of some number. A number can be written in the exponent form as aᵇ, where 'a' is called the base and 'b' is called the power or exponent.
Total land area of Russia = 20,000,000 km² = 2 × 10⁷ km²
Total land area of Puerto Rico = 10,000 km² = 10⁴ km²
Let X be the number of times that Russia is larger than Puerto Rico.
Then we can write,
Total land area of Russia = X × Total land area of Puerto Rico
2 × 10⁷ km² = X × 10⁴ km²
X = 2 × 10⁷ km² / 10⁴ km²
X = 2 × 10⁷ × 10⁻⁴
X = 2 × 10³
Hence, about 2 × 10³ times larger is Russia than Puerto Rico.

Ben had $100 in his savings account. He adds $5.00 a week to his savings as shown in the graph below. According to this graph, how much money does he have in his savings account after 8 weeks?
A. $40
B. $135
C. $140
D. $145
Answer:
Option (C)
Step-by-step explanation:
Let the relation between amount of money (m) and Time (t) is represented by the equation,
m = ct + b
Where c = Investment per week
b = Ben already had the amount before investment
From the question,
c = $5 per week
b = $100
Therefore, equation will be,
m = 5t + 100
If duration of the investment 't' = 8 weeks
Amount in the account after 8 weeks,
m = 5(8) + 100
m = $140
Option (C) is the correct option.

Use point-slope form to write a linear equation to represent the growth of Claire over time. Then, simplify the equation and write it in slope-intercept form. Identify the y-intercept. Show your work.
Complete Question:
The growth of baby girl Claire is displayed in the graph below. (4, 22) (14, 30)
Answer:
Point Slope: [tex]y - 22 = 0.8(x - 4)[/tex]
Slope Intercept: [tex]y = 0.8x +18.8[/tex]
y intercept: [tex]b = 18.8[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (4,22)[/tex]
[tex](x_2,y_2) = (14,30)[/tex]
Solving (a) Point slope
Using point slope form, an equation is of the form
[tex](y_2 - y_1) = m(x_2 - x_1)[/tex]
First, we need to solve for slope (m):
Make m the subject
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substitute values for x and y
[tex]m = \frac{30 - 22}{14 - 4}[/tex]
[tex]m = \frac{8}{10}[/tex]
[tex]m = 0.8[/tex]
Next, we form a linear relationship
[tex]y - y_1 = m(x - x_1)[/tex]
Where
[tex]m = 0.8[/tex] and [tex](x_1,y_1) = (4,22)[/tex]
[tex]y - 22 = 0.8(x - 4)[/tex]
Solving (b): Slope Intercept
[tex]y - 22 = 0.8(x - 4)[/tex]
Open Bracket
[tex]y - 22 = 0.8x - 3.2[/tex]
Add 22 to both sides
[tex]y - 22 +22= 0.8x - 3.2 + 22[/tex]
[tex]y = 0.8x +18.8[/tex]
Solving (c): The y intercept
The general form of an equation is:
[tex]y = mx + b[/tex]
Where b represents the y intercept
By comparison with [tex]y = 0.8x +18.8[/tex]
[tex]b = 18.8[/tex]

The sixth term of an arithmetic sequence is 3 2 , and the twelfth term is 5 2 . What is the common difference of the arithmetic sequence? The common difference is .
The sequence has a common difference, and the common difference of the arithmetic sequence is 10/3
How to determine the common difference?The given parameters are:
T6 = 32
T12 = 52
The nth term of an arithmetic progression is:
Tn = a + (n - 1) * d
So, we have:
T6 = a + 5d = 32
T12 = a + 11d = 52
Subtract both equations
a - a + 11d - 5d = 52 - 32
Evaluate
6d = 20
Divide both sides by 6
d = 10/3
Hence, the common difference is 10/3
