Answer:
x = 7
Step-by-step explanation:
From the above question, we are told that:
∠A and ∠B vertical angles.
It is important to note that vertical angles are equal to each other
Hence:
∠A = ∠B
From the question,
∠A = (5x−2)°
∠B = (3x+12)°
Hence:
(5x−2)°= (3x+12)°
5x - 2 = 3x + 12
Collect like terms
5x - 3x = 12 +2
2x = 14
x = 14/2
x = 7
Answer:
X=14

1) the sum of 8 and t
3) the product of 5 and b
Step-by-step explanation:
When we say sum we are referring to addition.
And a number and a variable(letter) can't be added. So the sum of 8 and t can't be added.
The sum of 8 and t is;
8+t
When we talk about product or finding the product of a number we are referring to the number we get after multiplying two or more numbers.
And note that with multiplication, a number and a variable(letter) can be multiplied.
The product of 5 and b is;
5×b=5b

The number of student of schoolwas 450 last year and it is 396 this year.By how many percent did the number decrease
Step-by-step explanation:
450 - 396 = 54
(54/450) * 100% = 12%
Hence the decrease is 12%.
Answer:
12%Step-by-step explanation:
The way to solve is to divide the number.
396/450 = 0.88 or 88%
Now, we subtract 88 from 100 to get 12, since we wanted the percent decrease.

The length of each of the two congruent sides of an isosceles triangle is 2n + 7 and the length of the third side is 3n. Write an expression for the length of the triangle’s perimeter.
Answer:
7n+14
Step-by-step explanation:
There are two sides that both measure 2n+7, we need 2 of those
2n+7+2n+7=4n+14
We still have the third side left, 3n.
4n+14+3n
combine like terms
7n+14
Solve the exponential equation: 6–2x = 62 – 3x
Question 1 options:
A)
4
B)
–2
C)
3
D)
2
Answer:
x = 56
Step-by-step explanation:
Collect like terms:6 - 2x = 62 - 3x
-2x + 3x = 62 - 6
1x = 56
x = 56
Check your answer:6 - 2(56) = 62 - 3(56)
6 - 112 = 62 - 168
-106 = -106

PLEASE ANYONE! I need to create a inequality equation to make this shape on the graph.
9514 1404 393
Answer:
-4 < y < 4 and y < -3/2x +2
Step-by-step explanation:
The boundary line crosses the y-axis at y=2. It intersects another grid point 2 units to the right and 3 units lower than that, so it has a slope of ...
m = rise/run = -3/2
This means we can write the boundary line equation as ...
y = mx + b
y = -3/2x +2
__
We notice that the line is dashed, and shading is below it. This means the shaded area will satisfy the inequality ...
y < -3/2x +2
We also notice that the range of the graph is from y = -4 to y = +4, so we must have ...
-4 < y < 4 and y < -3/2x +2
trina wrote forty- five and sixty five thousandths as 45.65. is her answer correct or error if so what is the error explain

Suppose that 8 female and 6 male applicants have been successfully screened for 5 positions. If the 5 positions are filled at random from the finalists, what is the probability of selecting (A) 3 females and 2 males? (B) 4 females and 1 male? (C) 5 females? (D) At least 4 females?
Answer:
0.4196
0.2098
0.0280
0.2378
Step-by-step explanation:
Given that:
Number of females = 8
Number of males = 6
Total = 8 + 6 = 14
Number of positions = 5
Probability = required outcome / Total possible outcomes
Total possible outcomes = 14C5
nCr = n! / (n-r)! r!
14C5 = 2002 (from calculator)
(A) 3 females and 2 males?
Required outcome : 8C3 * 6C2 = 56 * 15 = 840
840 / 2002 = 0.4196
(B) 4 females and 1 male?
(8C4 * 6C1) / 14C5 = 420 / 2002 = 0.2098
(C) 5 females?
8C5 / 14C5 = 56 / 2002 = 0.0280
(D) At least 4 females?
4 female 1 male + 5 females
((8C4 * 6C1) + 8C5) / 14C5
(420 + 56) / 2002 = 0.2378
