Answer:
x = -11
Step-by-step explanation:
Hello There!
create an equation
x + 51 + 60 + 80 = 180
combine like terms
51 + 60 + 80 = 191
x + 191 = 180
subtract 191 from each side
180 - 191 = -11
we're left with
x = -11

b) Here are the first four terms of another sequence.
7
11 15 19
Write an expression for the nth term of this sequence.
Answer:
[tex]a_{n}[/tex] = 4n + 3
Step-by-step explanation:
There is a common difference between consecutive terms, that is
11 - 7 = 15 - 11 = 19 - 15 = 4
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = 4 , then
[tex]a_{n}[/tex] = 7 + 4(n - 1) = 7 + 4n - 4 = 4n + 3

Answer:
Jessica's trains travels at a faster speed
Step-by-step explanation:
From the question,
Using the graph,
The total distance distance traveled by Khalid after 2 hours is
d = 280 mi.
S = d/t....................... Equation 1
Where S = Khalid's speed, d = Khalid's distance, t = time.
S = 280/2
S = 140 mph.
From the euqation,
The total distance traveled by Jessica after 2 hours is
y = 150×2
y = 300 mi.
Also Using
S' = d'/t
Where S' = Jessica's speed, d' = Jessica's distance
S' = 300/2
S' = 150 mph.
From the above, Jessica's trains travels at a faster speed

Leo has a lock box with a volume of 312 cubic inches. The box is 4 inches high and 13 inches long. What is the width of the box?
Answer:
6in
Step-by-step explanation:
Given data
Volume of the lockbox= 312 cubic inches
Height= 4in
Length= 13in
Width= ???
The expression for the volume of box is
V= L*W*H
substitute
312=13*W*4
312=52W
W= 312/52
W=6 in
Hence the width is 6in

x-axis. Then graph the figure and its reflected image.
Answer:
A'= (0,-4)
B'= (2,-1)
C'= (4,-3)
Step-by-step explanation:
After you flip it over the x-axis, it would be

Please helppp. Can you explain this?
Answer:
We have to find the value of x.
We need to substitute with 3 because they measure the same.
Step-by-step explanation:
(x - 1)
x - 1 = 3
x - 1 + 1 = 3 + 1
x = 4
(x + 1)
x + 1 = 5
x + 1 - 1 = 5 - 1
x = 4
Both answers are the same which means that they are correct.
This is a similar triangle please find the missing length. (?)
Answer:
33
Step-by-step explanation:
In ΔPQR,
length of side=
77= 7×11
84= 12
Similarly, In ΔFGH
length=
36=3×12
so, the other side= 3×11= 33
Answer:
33
Step-by-step explanation:
[tex]\frac{HG}{FG} =\frac{RQ}{PQ}[/tex], insert given values
[tex]\frac{?}{36}=\frac{77}{84}[/tex], cross multiply
84*?=36*77
84*?=2772, divide both sides by 84 to get ? by itself

Jack bought 4 hot dogs and 3 sodas for $15.50. Mack bought 3 hot dogs and 2 sodas for $11.25. Find the cost of each.
Answer:
Hot dogs: $2.75
Sodas: $1.5
Step-by-step explanation:
Hot dogs = x
Sodas = y
4x + 3y = 15.5
3x + 2y = 11.25
First find the value of the hot dogs by canceling out y:
2(4x + 3y) = 2(15.5)
3(3x + 2y) = 3(11.25)
= 8x + 6y = 31
9x + 6y = 33.75
x = $2.75 (Minus bottom equation from the top to isolate x)
Plug in for x to get y:
3(2.75) + 2y = 11.25
2y = 11.25 - 8.25 (Isolate the y)
2y = 3
y = 3/2, or $1.5

What is the exact circumference of the circle?
Answer:
circumference = 22.2144 or 5π√2
Step-by-step explanation:
the diameter of the circle would be equal to the diagonal of the square.
Using the Pythagorean theorem:
D² = 5² + 5²
D² = 50
D = 7.0711 or 5√2
circumference = πD = 5π√2 = 22.2144
Answer:
diagonal or diameter =√(5²+5²)=5√2unit
therefore radius =5/2√2unit
circumference of circle =2πr=2×π×5/2×√2=5π√2unit

What is an equation of a circle whose center is (1,4) and diameter is 10?
Question options:
x2 − 2x + y2 − 8y = 83
x2 − 2x + y2 − 8y = 8
x2 + 2x + y2 + 8y = 8
x2 + 2x + y2 + 8y = 83
Answer:
[tex]x^{2} - 2x + y^{2} - 8y = 8[/tex]
Step-by-step explanation:
Standard form for a circle is:
[tex](x - h)^{2} + (y - k)^{2} = r^{2}[/tex] (h, k) is the center r is the radius
[tex](x - 1)^{2} + (y - 4)^{2} = 5^{2} \\x^{2} - 2x + 1 +y^{2} - 8y + 16 = 25\\x^{2} - 2x + y^{2} - 8y = 8[/tex][tex]x^{2} - 2x + y^{2} - 8y = 8[/tex]

I NEED HELP ASAP
Answer:
30° = m∠GFH
Step-by-step explanation:
Since ∠EFH and ∠GFH are complementary, the sum of their measures i 90.
Let x = m∠GFH
2x = m∠EFH
m∠GFH + m∠EFH = 90
x + 2x = 90
3x = 90
