Answer:
the answer is n ≥ -49
here are the steps for solving-
the problem Is like n/7+3 ≥ -4
1. First subtract 3 from both sides. After doing that, the inequation should be Like This:

Given v^2 = u^2 − 2as. Solve for u, when v = 10, a = 5 and s = 2.
Answer:
u ≈ 11
Step-by-step explanation:
10² = u² - 2(5)(2)
100 = u² - 20
120 = u²
u = [tex]\sqrt{120}[/tex]
u = [tex]\sqrt{4}[/tex][tex]\sqrt{30}[/tex] = 2[tex]\sqrt{30}[/tex] which is 10.95

Make up an equation of the form y = kx +b, the graph of which passes through the following points:
P (4, 1) and Q (3, –5)
Answer:
y=6x-23
Step-by-step explanation:
Step-by-step explanation:
m = (y2 - y1)/(x2-x1)
m = (-5 -1)/(3-4) = -6/-1 = 6
y = 6x + b
then
slope point form
y - y1 = m (x - x1)
y - 1 = 6 (x - 4)
y - 1 = 6x - 24
y = 6x - 23

Answer:
148
Step-by-step explanation:
180 is the whole thing and if the inner of one is 16 then the other one is also 16 so u add this and subtract 180-32=148
(16+16=32)
Answer:
C. x=42
Step-by-step explanation:
First find the measurement of missing angles. 126+16=142
180-142=38
Now, 16, 3x and 38 should add up to 180 because it is a line.
16+38+3x=180
54+3x=180
Solve for x.
3x=126
3 = 3
x=42. Hope this helps.

Answer:
90
Step-by-step explanation:
each dot = 45 bc 540 / how many dots there are which is 12 = 45 then there are 2 dots worth of 45 making it 90
math
540/12=45
45 x 2 = 90
Answer: 135 students
Step-by-step explanation:
1. Divide 540 (total number of students) by the number of dots (12)
2. So then 540/12= 45
3. Then see how many dots are more then 5 miles away so that is 3 dots (2dots on 6 miles, and 1 dot on 7 miles)
4. After 45*3= 135
Use the data for the books each class donated for a book drive and find the upper quartile. 28 15 40 45 27 19 50 36 42 37 21 25
A.35
B.18
C.41
D.23
Answer:
41
Step-by-step explanation:
when you find the median you split the numbers in half from the upper to lower parts of the data. then you find the median of the upper part and that is the upper quartile.
median: 32
32, 36, 37, 40, 42, 45, 50
add 40+42 then divide by 2 and you get 41

Answer:
X:6.7
Y:17
Z:33
Step-by-step explanation:
Because their similar to each other, the corresponding angles are equal.
5y-3=82
5y=85
y=17
Angle J=angle M=z=180-82-65=33
3x-2=18.1
3x=20.1
x=6.7
Answer:
x = 6.7
y = 17
z = 33°
Step-by-step explanation:
To find x:
Because IJK≅LMN, you know that 3x-2 = 18.1
3x-2 = 18.1
Add 2 to both sides:
3x-2+2 = 18.1+2
3x = 20.1
Divide both sides by 3:
3x/3 = 20.1/3
x = 6.7
To find y:
5y-3 = 82
Add 3 to both sides:
5y-3+3 = 82+3
5y = 85
Divide both sides by 5:
5y/5 = 85/5
y = 17
To find z:
Because all triangles angles must add up to 180, find 180-82-65:
180-82-65 = 33 degrees
Because IJK≅LMN, z = 33 degrees

Hello! answer: 85
Step-by-step explanation:
Formula for square area: base × height
Formula for triangle area: base × height ÷ 2
6 × 5 = 30 30 ÷ 2 = 15 since theres 4 triangles I just multiply by 4 get all the triangles area so...
15 × 4 = 60 now the square is just 5 × 5 so... 5 × 5 = 25 now we just add these up for the answer so... 60 + 25 = 85 therefore the surface area is 85 hope that helps!
