Answer:
Step-by-step explanation:
Let us represent:
Short pieces = x
Middle pieces = y
Long pieces = z
A three foot long deli sandwich must be split into three pieces
x + y + z = 3
The middle piece is twice as long as the shortest piece
y = 2x
The shortest piece is 8 inches shorter than the longest piece.
x = z - 8
z = x + 8
We substitute
x + y + z = 3
x + 2x + x + 8 = 3
5x = 8 - 3
5x = 5
x = 5/5
x = 1
y = 2x
y = 2 × 1
y = 2
z = x + 8
z = 1 + 8
z = 7
How long should the three pieces be?

Step-by-step explanation:
I will solve your system by substitution.
(You can also solve this system by elimination.)
4x+y=17;4x−3y=−3
Step: Solve4x+y=17for y:
4x+y+−4x=17+−4x(Add -4x to both sides)
y=−4x+17
Step: Substitute−4x+17foryin4x−3y=−3:
4x−3y=−3
4x−3(−4x+17)=−3
16x−51=−3(Simplify both sides of the equation)
16x−51+51=−3+51(Add 51 to both sides)
16x=48
16/x = 48/16
(Divide both sides by 16)
x=3
Step: Substitute 3 for x in y=−4x+17:
y=−4x+17
y=(−4)(3)+17
y=5(Simplify both sides of the equation)
Answer:
x=3 and y=5

Answer:
∠P = 110º
∠Q = 70º
Step-by-step explanation:
we know that a straight line is equal to 180º and since we already have one angle (70º) all we have to do is subtract 70 from 180.
180 - 70 = 110º
we also know that vertical angles are congruent (the same) so we're already given angle q.

Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 3)(0,3) and (4, 7203)(4,7203).
Answer:
[tex]y = 3(7)^x[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (0,3)[/tex]
[tex](x_2,y_2) = (4,7203)[/tex]
Required
Determine an exponential function
Substitute 0 for x and 3 for y in [tex]y=ab^x[/tex]
[tex]3 = ab^0[/tex]
[tex]3 = a*1[/tex]
[tex]3 = a[/tex]
[tex]a = 3[/tex]
Substitute 4 for x and 7203 for y in [tex]y=ab^x[/tex]
[tex]7203= ab^4[/tex]
Substitute 3 for a
[tex]7203= 3*b^4[/tex]
Divide both sides by 3
[tex]2401= b^4[/tex]
Take 4th root of both sides
[tex]\sqrt[4]{2401} = b[/tex]
[tex]7 = b[/tex]
[tex]b = 7[/tex]
Substitute 3 for a and 7 for b in [tex]y=ab^x[/tex]
[tex]y = 3(7)^x[/tex]

Step 1: Define
-41 = -2/5(45n + 60) + n
Step 2: Solve for n
Distribute -2/5: -41 = -18n - 24 + nCombine like terms: -41 = -17n - 24[Addition Property of Equality] Add 24 on both sides: -17 = -17n[Division Property of Equality] Divide -17 on both sides: 1 = nRewrite/Rearrange: n = 1Step 3: Check
Plug in n into the original equation to verify it's a solution.
Substitute in n: -41 = -2/5(45(1) + 60) + 1(Parenthesis) Multiply: -41 = -2/5(45 + 60) + 1(Parenthesis) Add: -41 = -2/5(105) + 1Multiply: -41 = -42 + 1Add: -41 = -41Here we see that -41 does indeed equal -41.

Eight less than a number, n, is at least 10.
Which inequality represents this statement?
8- n > 10
n - 8 > 10
8- n < 10
n-8 < 10
Answer:
n - 8 >= 10
n minus 8 is greater than or equal to 10
Eight less than a number " n" , is at least 10.
The inequality for this condition can be represented as
[tex]\bold{ { n-8\geq 10}}\\[/tex]
Hence option (2) is correct
To find out the expression for this inequality let us consider that the number be ''n"
Since the actual number in the question is less than this number [tex]\rm n[/tex] by [tex]8[/tex] hence let the new number be [tex]\rm N[/tex]
From the given condition in the statement we can write that
[tex]\rm N = n-8[/tex]
According to the condition given in the statement we can write that
The value of [tex]\rm N[/tex] is at least 10. This means the minimum value for [tex]\rm N[/tex] is 10.
This signifies that N can be any number with minimum value 10.
So the inequality for this condition can be represented as
[tex]\rm\bold{ { N\geq 10}}\\\bold{ { n-8\geq 10}}\\[/tex]
Hence option (2) is correct

An account earns simple interest. Find the principal.
Interest earned: $27
Principal: ?
Interest rate: 1.5%
Time: 2 years
The principal is $
Answer:
$ 900
Step-by-step explanation:
Simple interest = Principle * Time * Rate / 100
Now by substituting :
27 = Principle * 2 * 1.5 / 100
Principle = 27 * 100 / 2 * 1.5
Principle = 2700 / 3
So Principle = $ 900
