Are they a system or separate inequalities? I'm not sure but either way I will solve each:
[tex]\begin{bmatrix}-3x+5>20\\ \frac{1}{2}x-12<6\end{bmatrix}[/tex]
[tex]-3x+5>20,\\-3x>15,\\x<-5[/tex]
[tex]\frac{1}{2}x-12<6,\\\frac{1}{2}x<18,\\x<36[/tex]
Now if it were a system, the solution would be x<-5, since x<36 is the restriction. Otherwise just take x<-5 and x<36 independent of each other.
Answer:
x< -5, x<36
Step-by-step explanation:
[tex]-3x+5>20} \atop {\frac{1}{2}x-12<6 }} \right. \\[/tex]
Start with the first equation and solve for x
-3x+5>20
-5 -5
-3x>15
/-3 /-3
x< -5
Do the second:
[tex]\frac{1}{2}x-12<6[/tex]
+12 +12
[tex]\frac{1}{2}x[/tex]<18
/0.5 /0.5
x< 36

In September, Louise planted a tree. Every month, the tree Louise planted grew 2 inches. What would the constant of proportionality of the line be?
Answer:
1/2
Step-by-step explanation:
Tree grow 2 inches per month
Let :
Month = m ; height increase, h
m α h
m = kh
k = proportionality constant
Where ; m = 1 ; h = 2
1 = 2k
1/2 = 2k/ 2
k = 1/2
Answer:1/2

Greg chose C as the answer. How might he have gotten that answer?
Given:
The equation is
[tex]-0.4x+0.05y-1.25=0[/tex]
Where, y is the total cost and x is the number of months.
To find:
The y-intercept of the line represented by this equation.
Solution:
We have,
[tex]-0.4x+0.05y-1.25=0[/tex]
Isolate y variable.
[tex]0.05y=0.4x+1.25[/tex]
Divide both sides by 0.05.
[tex]y=\dfrac{0.4x+1.25}{0.05}[/tex]
[tex]y=\dfrac{0.4x}{0.05}+\dfrac{1.25}{0.05}[/tex]
[tex]y=8x+25[/tex]
Putting x=0, we get
[tex]y=8(0)+25[/tex]
[tex]y=0+25[/tex]
[tex]y=25[/tex]
Therefore, the y-intercept of the given equation is 25 and the correct option is D.
help me please I'm struggling
Answer:
cookies = 20%
cheese sticks= 26.7%
chips= 40%
water= 13.3%
Step-by-step explanation:
there a 30 items in total.
simply take the number of each item sold and divide it by 30.
for example, for cookies:
6÷30= 0.2
to turn a decimal into a percentage, multiply by 100.
therefore, 0.2×100= 20%
hope this helps!
Answer:
20%
28 2/3%
14 1/3%
14 1/3%
Step-by-step explanation:
we know the whole is 30, so we make fractions out of the table and simplify
6/30=1/5
8/30=4/15
12/30=2/5
4/30=2/15
1/5=0.2, so the percent is 20%
4/15=28 2/3%
2/15=0.143333333 forever, so 14 1/3%
4/30=same as the second to last, 14 1/3%

Answer:
10°, 80°
Step-by-step explanation:
Setup
Let x and y represent the measures of the two acute angles in the right triangle.
From your knowledge of right triangles, you know the two acute angles are complementary:
x + y = 90
The problem statement gives you another relation:
x = 2(y + 30) . . . . twice the sum ...
__
Solution
The second equation gives you an expression for x that can be substituted into the first equation.
(2(y +30)) + y = 90
3y +60 = 90 . . . . . . . . collect terms
3y = 30 . . . . . . . . . subtract 60
y = 10 . . . . . . . . divide by 3
x = 2(y +30) = 2(40) = 80
The two angles are 10° and 80°.

An object is projected vertically upwards from ground level. When asked a question about its maximum height, you should use: A) S=0 B) U=0 C) V=0 D) A=0
Answer:
[tex]V = 0[/tex]
Step-by-step explanation:
Given
At maximum height
Required
Select which of the options is true
At the maximum height of an upward projectile, the final velocity (v) is always equal to 0.
i.e.
[tex]V = 0[/tex]
Other parameters such as initial velocity (u), acceleration (a or g) are not 0.
Hence:

Pedro is getting balloons for his grandmother's birthday party. He wants each balloon string to be 12 feet long. At the party store, string is sold by the yard. If Pedro wants to get 52 balloons, how many yards of string will he need? 1 foot = 1 3 yard
Answer:
Total length of string required in yards [tex]8112[/tex] yards
Step-by-step explanation:
The length of the string attached with each balloon is equal to [tex]12[/tex] feet
In the party total number of balloon used is equal to [tex]52[/tex] balloons
The total length of the string required
Length of string used in one balloon * total number of balloons
[tex]= 12 * 52 = 624[/tex] feet
1 feet is equal to 13 yards
Total length of string required in yards [tex]13 * 624 = 8112[/tex] yards
Write the equation of the line that includes the point (3,3) and has a slope of 2.
Answer:
y = 2x - 3
Step-by-step explanation:
We are given the slope, m = 2
Our standard formula of a line is y = mx + b, so we can substitute for the x and y values of the point (3, 3). If you did not know, the x-value and the y-value are both 3 because the point (3, 3) = (x, y).
So, our equation looks like this:
3 = (2)(3) + b
We can solve for b:
3 = 6 + b
b = -3
And now we have our equation of a line:
y = 2x - 3

Lucy solves 1.8 ÷ 0.3 using the work below.
Lucy's work is incorrect. Explain Lucy's mistake and write what the correct answer should be. Please write your response in complete sentences.
Answer:
Lucy's mistake is that she didn't move the decimal in 1.8 as well. The correct answer should be 6.
Step-by-step explanation:
Since Lucy multiplied 0.3 by 10, she also needed to multiply 1.8 by 10 to keep the equation proportional.
