'4 more than a number' implies that there exists a number which is 4 units greater than the original number, using the concept of addition.
Addition (usually signified by the plus symbol +) is one of the four basic operations of arithmetic, the other three being subtraction, multiplication and division.The addition of two whole numbers results in the total amount or sum of those values combined. The example in the adjacent image shows a combination of three apples and two apples, making a total of five apples. This observation is equivalent to the mathematical expression "3 + 2 = 5" (that is, "3 plus 2 is equal to 5").
Besides counting items, addition can also be defined and executed without referring to concrete objects, using abstractions called numbers instead, such as integers, real numbers and complex numbers. Addition belongs to arithmetic, a branch of mathematics. In algebra, another area of mathematics, addition can also be performed on abstract objects such as vectors, matrices, subspaces and subgroups.
Now, let us understand the meaning.
Let the original number be x.
'4 more than a number' implies x + 4.
This means that the new number, x + 4, is greater than the original number, x, by 4 units. We also have to keep in mind, [tex]x + 4 > x[/tex].
Hence, the final meaning is 4 units greater than the original number.

Canidate B recieved 5 times as many votes as Canidate A. The ratio of votes for Candidate B to votes for Canidate A is?
Answer:
The ratio of votes is 5:1
Step-by-step explanation:
Here, we want to find the ratio of votes
From the question, candidate B received 5 times of what candidate A received
so lest day candidate B received 25, candidate A will receive 5
So the ratio of votes for B to A will be ;
25 : 5
To the smallest term, this is 5:1
Find a30 of the arithmetic sequence:
−17,−7,3,13,...
Answer:
a₃₀ = 273
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 17 and d = a₂ - a₁ = - 7 - (- 17) = - 7 + 17 = 10 , then
a₃₀ = - 17 + (29 × 10) = - 17 + 290 = 273

Ah Algebra...
2x-3y=-1
y=x-1
Let's solve your system by substitution.
2x−3y=−1; y=x−1
Rewrite equations:
y=x−1;2x−3y=−1
Step: Solve
y= x−1
Step: Substitute x−1 for y in 2x−3y=−1:
2x−3y=−1
2x−3(x−1)=−1
−x+3=−1(Simplify both sides of the equation)
−x+3+−3=−1+−3(Add -3 to both sides)
−x=−4−x−1=−4−1
(Divide both sides by -1)
x=4
Step: Substitute4forxiny=x−1:
y=x−1
y=4−1
y=3(Simplify both sides of the equation)
Answer:
x=4 and y=3
Hope this helps :)
Stay Cold,
Brook
Answer:
(4,3)
Step-by-step explanation:
Being that the y variable is isolated in the second equation, the other side of that equation can be substituted for y in the first equation.
[tex]2x - 3(x - 1) = - 1[/tex]
Now simplify for x.
[tex]2x - 3x + 3 = - 1 \\ - x = - 4 \\ x = 4[/tex]
Now with that, insert the x value in for x in the second equation.
[tex]y = (4) - 1 \\ y = 3[/tex]
Now the correct answer is (4,3)

Solve for x in the parallelogram below:
X=??
Answer:
x = 4
Step-by-step explanation:
Consecutive angles in a parallelogram are supplementary, sum to 180°, so
14x + 6 + 118 = 180
14x + 124 = 180 ( subtract 124 from both sides )
14x = 56 ( divide both sides by 14 )
x = 4
Answer:
x = 4Step-by-step explanation:
Adjacent angles of a parallelogram are supplementary
14x + 6 + 118 = 18014x + 124 = 18014x = 180 - 12414x = 56x = 56/4x = 4

First, solve 9.30 x 10^7 to find the length of an astronomical unit.
10^7 = 10000000
9.30x10000000=93000000 miles
next, solve for the distances the sun is from Jupiter and Mars,
10^8 = 100000000
1.42x100000000=142000000 miles
4.84x100000000=484000000 miles
next, subtract the distances
484000000-142000000=342000000 miles
then, divide the sum by 93000000 to find the amount in astronomical units.
342000000/93000000=3.677419
finally, round to the nearest hundred

What is the length of the unknown leg in the right triangle?
Answer:
15m
Step-by-step explanation:
a^2 + b^2 = c^2
a=?
b = 20m
c = 25m
a^2 + (20m)^2 = (25m)^2
a^2 + 400m^2 = 625m^2
a^2 = 625m^2 - 400m^2 = 225m^2
a = 15m

Natalie invests $5,632 in a retirement account with a fixed annual interest rate of 2% compounded 12 times per year. What will the account balance be after 16 years?
A) $8,398.46
C) $7,753.92
B) $8,610.85
D) $7,910.43
Answer:
C) $7,753.92
Step-by-step explanation:
Given data
Principal= $5,632
Rate=2%
n= 12
Time = 16 years
The expression for compound interest is
A=P(1+r/n)^nt
substitute
A= 5632(1+0.02/12)^12*16
A=5632(1+0.02/12)^12*16
A= 5632(1+0.00166)^12*16
A= 5632(1.00166)^12*16
A= 5632(1.00166)^192
A=5632*1.375
A=$7744
Hence the approximate amount is C) $7,753.92
8. Coffee Country City Council has decided to build a new road to connect Main Street
and Lincoln Lane (see the drawing). If construction costs $25,000 per mile, how much
will it cost?
Main Stream
3 mil
Lincoln Ln
1.5 miles-
NEW ROAD
Answer:
easy just pull put calculator and add 25,000 with 3 mil
Step-by-step explanation:
Answer:
Cost 64951.91
Step-by-step explanation:
We are to assume that the new road and Lincoln Lane meat at right angles. If that is true we can use the Pythagorean Theorem.
Givens
a = 1.5 miles
b = ?
c = 3 miles
Cost per mile = 25000
Solution
a^2 + b^2 = c^2
1.5^2 + b^2 = 3^2
2.25 + b^2 = 9
b^2 = 9 - 2.25
b^2 = 6.75
sqrt(b^2) = sqrt(6.75)
b = 2.5981
Cost
1 mile costs 25000
2.5981 costs x
1/2.5981 = 25000 / x Cross Multiply
x = 2.5981 * 25000
x = 64951.91

b = 6, A = 20°; - I just need Help finding a and c
Step-by-step explanation:
tan 20 = a/6

c = √ 40.84
c = 6.38 = 6.4
A trapezoid has a height of 6 inches, an area of 120 inches, and one base measuring 14 inches. Find the length of the other base
Answer:
26 inches
Step-by-step explanation:
Area of a trapezoid = [tex]\frac{1}{2}[/tex](a + b) x h
a and b = 2 parallel sides
h = height
120 = 0.5(14 + b) x 6
120 = 3 x (14 +b)
Divide both sides of the equation by 3
120/3 = 14 + b
40 = 14 + b
Collect like terms
b = 40 - 14 = 26inches

Writing the Standard Form of a Line
Try it
Write the equation of the line that passes through the points (8, -1) and (2,-5) in standard form, given that the point
slope form is y + 1 = 2/3 (x – 8).
____x + ____y = ____
Answer:
[tex]2x-3y = 19[/tex]
Step-by-step explanation:
In standard form, represented by the formula [tex]Ax+By=C[/tex], all the constants and coefficients of the terms are integers, the terms have no common factors (besides 1), and the number in place of A is positive. Knowing this, convert the equation to standard form like so:
[tex]y+1=\frac{2}{3} (x-8)\\y+1 = \frac{2}{3} x-\frac{16}{3} \\-\frac{2}{3} x+y+1 = -\frac{16}{3} \\-\frac{2}{3}x+y = -\frac{16}{3} -1\\-\frac{2}{3} x+y = -\frac{16}{3} -\frac{3}{3} \\-\frac{2}{3} x+y = -\frac{19}{3} \\2x-3y = 19[/tex]
