6(-3x+8)=-3(5x +4)
Distributive property:
-18x + 48 = -15x -12
Add 15x to both sides:
-3x + 48 = -12
Subtract 48 from both sides:
-3x = -60
Divide both sides by -3:
x = -60 / -3
x = 20

josefina pain rent for 5 months. She paid a total of $2045. how much did she pay per month?
Answer:
$409 per month
Step-by-step explanation:
If josefina paid $2045 over a time period of 5 months, then we have to divide how much she paid ($2045) by 5 to find out how much she paid for rent in 1 month.
We can use the equation: 2045 ÷ 5
When we solve that equation, we get 409 which means that josefina paid $409 per month for rent.

Step-by-step explanation:
Students who attend Anytown College pay either in-state or out-of-state tuition, depending on where they reside. The amount, I, spent on in-state tuition for a randomly selected student has a mean of $2,523.75 and a standard deviation of $1,003.25. The amount, O, spent on out-of-state tuition for a randomly selected student has a mean of $3,825.00 and a standard deviation of $1,126.50.
Suppose we randomly select one student who pays in-state tuition and one student who pays out-of-state tuition.
Calculate the mean of the sum S = I + O.
μS = $227.69
μS = $1,301.25
μS = $1,508.48
μS = $6,348.75
Answer:
6,348.75
Step-by-step explanation:
Just add the means. It’s right, just did it!
Using statistical concepts, it is found that the mean of the sum S = I + O is of:
[tex]\mu_S = 6348.75[/tex]
What happens when two variables are added?When two variables are added, the mean is the sum of the means, while the standard deviation is the square root of the sum of the variances.In this problem:
The mean of I is of [tex]\mu_I = 2523.75[/tex].The mean of O is of [tex]\mu_O = 3825.00[/tex].S is the sum of I and O, hence:
[tex]\mu_S = \mu_I + \mu_O = 2523.75 + 3825.00 = 6348.75[/tex]

Solve 3x + 4(x + 6) = 45.
Answer:
x=3
Step-by-step explanation:
3x + 4(x + 6) = 45
Distribute
3x+4x+24 = 45
Combine like terms
7x+24 = 45
Subtract 24 from each side
7x+24-24 = 45-24
7x = 21
Divide each side by 7

What is the perimeter of the triangle, the left diagonal side is 6.1in, the right diagonal side is also 6.1in, the bottom line is 7in, and there is a line in the middle from top to bottom which is 5in. What is the perimeter of the triangle?
Answer:
19.2 inches
Step-by-step explanation:
6.1 + 6.1 + 7 = 12.2 + 7 = 19.2
perimeter is the outside distance of the shape so you don't need to know the altitude (or height) equals 5.

Enter a value for x that makes the equation -2x + 10 + 4x = 70 true
Answer:
x = 30
Step-by-step explanation:
- 2x + 10 + 4x = 70, that is
2x + 10 = 70 ( subtract 10 from both sides )
2x = 60 ( divide both sides by 2 )
x = 30
write the equation for the parabola that has x-intercepts (2,0) and (3,0) and y intercept (0,-1.2)
Answer:
i think its y=-0.2x^2+x-1.2
Step-by-step explanation:
i could be wrong tho ngl
The equation of the parabola with x-intercepts (2,0) and (3,0) and y-intercept (0,-1.2) will be y = (-1/5)(x - 2)(x - 3).
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
The graph is easy to understand the behavior of the graph.
For example y = x² form a parabola now by looking at only the graph we can predict that it has only a positive value irrespective of the interval of x.
The equation of a parabola is written as,
y = a(x - b)(x - c) here b and c are two x-intercepts while (a,y) is the y-intercept.
As per the given,
x-intercept = (2,0) and (3,0)
y-intercept = (0,-1.2)
y = a(x - 2)(x - 3)
-1.2 = a(0 - 2(0 - 3)
a = -1/5
Thus,
y = (-1/5)(x - 2)(x - 3)
Hence "The equation of the parabola with x-intercepts (2,0) and (3,0) and y-intercept (0,-1.2) will be y = (-1/5)(x - 2)(x - 3)".

Find the value of x in the triangle. SU RV
Answer:
x = 8
Step-by-step explanation:
Δ TSU and Δ TRV are similar , thus the ratios of corresponding sides are equal, that is
[tex]\frac{TS}{TR}[/tex] = [tex]\frac{TU}{TV}[/tex] , substitute values
[tex]\frac{x}{x+16}[/tex] = [tex]\frac{5}{15}[/tex] = [tex]\frac{1}{3}[/tex] ( cross- multiply )
3x = x + 16 ( subtract x from both sides )
2x = 16 ( divide both sides by 2 )
x = 8

Answer:
1.7 miles
Step-by-step explanation:
Given that,
Jacob walks 1.5 miles north.
He turns and walks 0.8 miles west.
We need to find how far is he from his starting point. Let he is at a distance of x miles from the starting point. It can be calculated as follows :
[tex]x=\sqrt{1.5^2+0.8^2} \\\\x=1.7\ \text{miles}[/tex]
Hence, he is 1.7 miles from his starting point.

Jen used 1/2 cup of cereal and 2/3 cup of nuts to make trail mix. Her mother asked if she used more cereal or more nuts in the mix. Which statement correctly compares the fractions?
1/2<2/3. 1/2= half of a whole and half of a whole is 1/2. 2/3 is over a half so it means that 2/3 is better then 1/2 since 1.5 is actually the half of 3. Jen should say that she used more nuts to make trail mix then using cup of cereal to make trail mix because 2/3 is greater then 1/2.
A 12-meter ladder leans against a building forming a 30° angle with the building.
Exactly how high is the ladder on the building in meters? Round to the nearest hundredth
(2 digits after the decimal).
Answer:
will show you two (2) ways to solve this problem.
A diagram is needed to see what is going on....
Without loss of generality (WLOG)
The wall is on the right. The ladder leans against the wall
with a POSITIVE slope, from SW to NE (quadrant 3 to quadrant 1).
The measure from the bottom of the ladder to the wall is 6.
Option 1:
The ladder, ground and wall form a right triangle.
The hypotenuse (ladder) is 14 feet.
The bottom of the ladder is 6 feet from the wall,
so the base of this right triangle is 6 feet.
The top of the ladder to the ground represents
the missing leg of the right triangle.
The pythagorean theorem applies, which says
6^2 + h^2 = 14^2 where h is the height
of the top of the ladder to the ground
36 + h^2 = 196
h^2 = 196 - 36
h^2 = 160
h = sqrt(160)
= sqrt(16 * 10)
= sqrt(16)* sqrt(10)
= 4*sqrt(10) <--- exact answer
= 4 * 3.16227766016838....
= 12.64911....
12.65 <--- rounded to 2 digits as directed
----------------------------------------------
Option #2: using trig
With respect to the angle formed by the bottom of the
ladder with the ground
cos T = 6/14 = 3/7
T = inverse-cosine(3/7) = 64.623006647 degrees
sin(64.623006647) = h/14
h = 14*sin(64.62300647) = 12.6491106 <--- same answer
hope this helps
