Step-by-step explanation:
Take 10 from both sides
t/2 + 10 - 10 = -40 - 10 Combine like terms
t/2 = - 50 Multiply both sides by 2
2*t/2 = -50*2
t = - 100

Geoffrey is trying to earn $50 to buy a video game. He has saved $14.25. He earns $3.75 per hour cleaning windows with his uncle and he earns $6.50 per hour working at the grocery store. Can Fred buy the video game if he works with his uncle for 3 hours and at the grocery store for 4 hours? Use the inequality 3.75y + 6.50z + 14.25 ≥ 50.
Yes, because the total will be $51.50.
Yes, because the total will be $60.25.
No, because the total will be $24.50.
No, because the total will be $37.25.

x = 3, y = 5
Question 5(Multiple Choice Worth 4 points)
(07.01)
Which of the following sets shows all the numbers from the set {1, 2.5, 3, 4.5, 5} that make the inequality 3a + 4 ≥ 13 true?
{2.5, 3, 4.5}
{1, 2.5}
{3, 4.5, 5}
{4.5, 5}
Answer:
Step-by-step explanation:
1) 2x+ 4 = 10
2x = 6
x = 3 (3 is the answer)
2) we have to substitute y with 3 and z with 4
3.75*3 + 6.50*4 ≥ 50
11,25 + 26 ≥ 50
37.25 ≥ 50
so the answer is no, because the total will be $37.25
3) 12k + 2 < 12
12k < 10
k < 5/6
3/4 < 5/6 so the answer is true
4) we have to try the options
a) 3*4 + 4*2 + 6 = 26
12 + 8 + 6 = 26
26 = 26 (true)
b) 3*5 + 4*6 + 6 = 26
15 + 24 + 6 = 26
45 = 26 (false)
c) 3*4 + 4*3 + 6 = 26
12 + 12 + 6 = 26
30 = 26 (false)
d) 3*3 +4*5 + 6 = 26
9 + 20 + 6 = 26
35 = 26 (false)
so the answer is x=4 , y=2
5) 3a + 4 ≥ 13
3a ≥ 9
a ≥ 3
so the answer is {3,4.5,5}

You wonder if weather (rain, cloudy or sunny) makes a difference on mood (happy or not). To determine this, you sample the moods of 200 people on a sunny day, 200 people on a rainy day and 200 people on a cloudy day and record whether they were happy or not. You then want to do a chi square test on this data. What are the degrees of freedom?
Answer:

What is the area of triangle BCD to the nearest tenth of a square centimeter? Use special right triangles to
help find the height. Show your work.
Answer:
Area = 13.8 cm²
Step-by-step explanation:
Area of a triangle = ½*base*height
base = 4 cm
height = ?
Find height using trigonometry function:
Reference angle = 60°
Opp = height = BC
Adj = 4 cm
Apply TOA:
Tan 60 = Opp/Adj
Tan 60 = BC/4
BC = 4*Tan 60
BC = 6.92820324 ≈ 6.9 cm
✔️Area of triangle = ½*4*6.9
= 13.8 cm²
What is m∠G to the nearest tenth?
Answer:
Step-by-step explanation:

Write 3 equivalent ratios for each ratio given.
6.25 to 1.25
Answer:
3 equivalent ratios are: [tex]\frac{62.5}{12.5}, \frac{625}{125}, 5[/tex]
Step-by-step explanation:
Ratio of a to b:
The ratio of a to b is given by:
[tex]\frac{a}{b}[/tex]
Finding equivalent ratios:
To find equivalent ratios, we multiply or divide both a and b by the same value.
6.25 to 1.25
[tex]\frac{6.25}{1.25}*\frac{10}{10} = \frac{6.25*10}{1.25*10} = \frac{62.5}{12.5}[/tex]
[tex]\frac{6.25}{1.25}*\frac{100}{100} = \frac{6.25*100}{1.25*100} = \frac{625}{125}[/tex]
[tex]\frac{\frac{6.25}{1.25}}{{\frac{1.25}{1.25}}} = 5[/tex]
3 equivalent ratios are: [tex]\frac{62.5}{12.5}, \frac{625}{125}, 5[/tex]

A positive angle less than 360 that is coterminal with -725 degrees is
The positive angle is less than 360 which is coterminal with -725 degrees is 85 degrees.
What are Coterminal Angles?Coterminal angles are those with the same beginning side and the same terminal sides. These angles are in the typical position, although their values differ. They have the same sides, are in the same quadrant, and their vertices are identical. The endpoint sides coincide at the same angle when the angles are rotated clockwise or anticlockwise.
An angle that is coterminal with -725 degrees is an angle that has the same initial and terminal sides as -725 degrees, but its measure is between 0 and 360 degrees.
To determine a positive angle less than 360 that is coterminal with -725 degrees, we can add or subtract multiples of 360 from -725 degrees until we get an angle within that range.
In this case, -725 degrees - (2 x 360) = -725-720= -1445.
So, the positive angle less than 360 that is coterminal with -725 degrees is -1445 degrees + 360 = 85 degrees.

-2x - 9y = -3
--7x - 9y = -33
Answer:
x = 6 and y = -1
Step-by-step explanation:
hope this helps
Answer:
x= 6 and y= -1
Step-by-step explanation:
-2x - 9y = -3
-7x - 9y = -33
I'm going to be solving by elimination. However, you can solve using substitution as well.
So the first step is to eliminate one of the variables. In my opinion, what's easiest is eliminating the y variables. To eliminate you want to variables (that are the same) to equal 0 and cancel out. To do this, all I have to do is subtract. When I subtract I get 0 as shown below. I will also subtract the other variables and numbers in the equations because that's how elimination works.
-2x - 9y = -3
-7x - 9y = -33
5x = 30
-2 - (-7)=5 and -3 - (-33)= 30
There's no solution for the y variable because -9 - (-9)=0, which cancels out so it doesn't have to be written.
after that you get x=6 because you divide by 5 on both sides.
All that's left is to plug in 6 to one of the equations:
-2(6) - 9y= -3
-12 - 9y= -3
+12 +12
-9y= 9
Divide both sides by -9 to get y= -1
