Write the algebraic expression for ‘x plus five is twenty three’
Answer:
x + 5 = 23
Step-by-step explanation:
Just write it like how you say it.
The algebraic expression for the given phrase is x+5=23.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given phrase is "x plus five is twenty three"
Here, the equation is x+5=23
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Transpose 5 to the RHS of the equation, we get
x=23-5
x=18
Therefore, the x value is 18.

Given that the measure of ∠ is 45°, and the measure of ∠ is 49°, find the measure of ∠.
Answer:
86º
Step-by-step explanation:
If this is a trriangle the sum of the angles is 180º

Answer:
6 runners
Step-by-step explanation:
Complete question
A relay race covers 1 1/2 kilometers, and each runner on a team will run 1/4 of a kilometer. How many runners are needed for a team?
Given that;
1 runner = 1/4 km
If a relay race covers 1 1/2 km, hence;
x runner = 1 1/2 km
Divide both expressions
1/x = (1/4)÷(1 1/2)
1/x = 1/4 ÷ 3/2
1/x = 1/4 * 2/3
1/x = 2/12
Cross multiply
2x = 12
x = 12/2
x = 6
Hence 6 runners are needed for the race
what is the product of 3.4* 10^2 and 1.8* 10^3 expressed in scientific notation
Answer:
6.12 x 10⁵
Step-by-step explanation:
You just multiply 3.4 and 1.8 which gives 6.12
And for the notation you add the exponents 2 and 3 which give 5
Answer:
6.12 × 10^5.
Step-by-step explanation:
3.4 × 10² × 1.8 × 10³
To solve this, we can group.
[tex](3.4 * 1.8) * (10^2 * 10^3) =[/tex] [tex](6.12) *(10^5).[/tex]

Please help me with 1,2,3,4 and show me how you get it the answers
Answer:
Step-by-step explanation:
Use the formula of distance between the two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex],
Distance = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
1. Distance between A(3, 4) and B(8, 12),
AB = [tex]\sqrt{(8-3)^2+(12-4)^2}[/tex]
AB = [tex]\sqrt{25+64}[/tex]
= [tex]\sqrt{89}[/tex]
≈ 9.43
2. Distance between C(-2, 10) and D(3, -2),
CD = [tex]\sqrt{(3+2)^2+(-2-10)^2}[/tex]
= [tex]\sqrt{25+144}[/tex]
= [tex]\sqrt{169}[/tex]
= 13.00
3. Distance between X(20, 4) and Y(17, 0),
XY = [tex]\sqrt{(20-17)^2+(4-0)^2}[/tex]

Which equation results from adding the equations in this system?
-2x+y = 8
5x-y=-5
O 7x=13
O 7x=3
O 3x=3
3x= 13
Answer: 3x=3
Step-by-step explanation: Let's divide this into parts--
1. Adding the x variables: -2x+5x or 5x-2x = 3x.
2. Adding the y variables: y-y or -y+y = 0. (The negative and the positive y cancel each other out.)
3. Adding the numbers: 8-5 or -5+8 = 3.
Now just put it back into an equation: 3x + 0 = 3.
We don't need to add the 0, so the equation changes into 3x = 3.
Find the missing side or angle.
Round to the nearest tenth.
B=45°
a=9
c=19
b=[ ]
Answer:
[tex]14.1[/tex]
Step-by-step explanation:
Since we have two sides of a triangle and the angle between them, we can use the Law of Cosines.
For any triangle, the Law of Cosines states:
[tex]b^2=a^2+c^2-2ac\cos B[/tex], where [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] are all interchangeable.
Substituting given values, we have:
[tex]b^2=9^2+19^2-2(9)(19)\cos 45^{\circ},\\b^2=200.169480834,\\b\approx \boxed{14.1}[/tex]
has a y-intercept of (0,2) and passes through the point (3,128)
Answer:
y = 42x + 2
Step-by-step explanation:
The equation of a line is expressed as y = mx+b
Slope = y2-y1/x2-x1
Slope = 128 - 2/3-0
Slope m = 126/3
Slope = 42
Since the y intercept is (0, 2), hence b = 2
Get the equation;
Recall that y = mx+b
y = 42x + 2
This gives the required equation

Daniel drew a toy from a treasure chest containing 30 different toys. He selected a bouncy ball without replacement and then selected a key chain. What is the probability this could occur
Answer:
[tex]Pr = \frac{1}{870}[/tex]
Step-by-step explanation:
Given
[tex]n =30[/tex]
Required
Probability of selecting 2 toys of different types
From the question, we understand that all toys are different i.e. 1 of each type.
And the selection is without replacement;
So, after the first toy is selected; there are n - 1 toys left.
So, the probability is:
[tex]Pr = \frac{1}{n} * \frac{1}{n - 1}[/tex]
Substitute [tex]n =30[/tex]
[tex]Pr = \frac{1}{30} * \frac{1}{30- 1}[/tex]
[tex]Pr = \frac{1}{30} * \frac{1}{29}[/tex]
[tex]Pr = \frac{1}{30*29}[/tex]
[tex]Pr = \frac{1}{870}[/tex]

The diameter of a planet is about 25,660 mi. The diameter of the planet's moon is about 35% of the diameter of the planet. What percent of the volume of the planet is the volume of its moon?
The volume of the planet's moon is % of the volume of its planet.
(Round to the nearest whole number as needed.)
Answer:
4%
Step-by-step explanation:
Volume of sphere
v = (4/3)πr^3
Volume moon/ volume planet
We don't actually need the numeric value of the radius
just the 35% ratio
Radius of moon = .35 radius of planet
Vm/ Vp = (4/3)π(.35r)^3 / (4/3)π(r)^3
Cancel like terms
Vm / Vp = .35^3
Vm / Vp = 0.042875
Expressed as a percentage
Vm / Vp = 4.2875%
Rounded
Vm / Vp = 4%
