Your answer is 27
Step-by-step explanation:
4 x 3 = 12
5 x 3 = 15
12 + 15 = 27
4x+1= 2x +7
How to solve this equation?
Answer:
3
Step-by-step explanation:
4x +1 =2x +7
4x - 2x =7 - 1
2x =6
x=6 :2

“Identify the CORRECT formula based on the sequence” do not answer on some bs .
Answer:
see explanation
Step-by-step explanation:
there is a common ratio between consecutive terms , that is
21 ÷ 7 = 63 ÷ 21 = 3
this indicates the sequence is geometric with explicit formula
[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]
where a₁ is the first term and r the common ration
here a₁ = 7 and r = 3 , then
[tex]a_{n}[/tex] = 7 . [tex]3^{n-1}[/tex] ← explicit formula
the recursive formula allows a term to be found by multiplying the previous term by r , then
[tex]a_{n}[/tex] = 7 . [tex]a_{n-1}[/tex] ← recursive formula

Mike bought an item online for $60 and he was charged a $3 shipping fee. What percent of the sale price was the shipping fee?
Answer:
5%
Step-by-step explanation:
Given the following question:
The item costs 60 dollars
The shipping costs was 3 dollars
What was the percent of 60 is 3?
To find the answer we divide the shipping fee by the cost and then multiply the answer by 100.
[tex]\frac{3}{60} =3\div60=0.05\times100=5[/tex]
[tex]=5[/tex]
3 dollars is "5 percent" of 60 dollars.

The equation of a line given two points needs to be found. Samuel claims that slope-intercept form will generate the equation and Helena claims that point-slope form will find the equation. Who is correct? Explain your reason by describing both forms.
Please help me with this question.
The answer is:put the equation xa+yb=1 to the slope intercept form and find its slope and y-intercept.
Sample Answer: Both are correct. Using either form will result in the same equation. The slope-intercept form uses slope and a point to find the y-intercept. Point-slope form uses the slope and a point to solve for y to generate the equation.

Answer:
12a. 45+0.5x+2x+x = 150
12b. the three unknown sides are 30ft, 60ft, and 15ft.
Step-by-step explanation:
12a. the fence is 150ft. so
45+0.5x+2x+x = 150
12.b solve the equation from 12a.
45+0.5x+2x+x = 150
7x/2 = 105
7x = 210
x= 30
0.5(30) = 15ft
2(30)=30ft
x= 30ft
the three unknown sides are 30ft, 60ft, and 15ft.
Answer:
12a. 45+0.5x+2x+x = 150
12b. the three unknown sides are 30ft, 60ft, and 15ft.
Step-by-step explanation:
12a. the fence is 150ft. so
45+0.5x+2x+x = 150
12.b solve the equation from 12a.
45+0.5x+2x+x = 150
7x/2 = 105
7x = 210
x= 30
0.5(30) = 15ft
2(30)=30ft
x= 30ft
the three unknown sides are 30ft, 60ft, and 15ft.
Given f(x) = 3x- 1 and g(x) = 2x-3, for which value of x does g(x) = f(2)?
Options:
A)x=3/2
B)x=2
C)x=5/2
D)x=4
Answer: x = 4
Step-by-step explanation: f(2) = 3(2)-1 = 5. Meaning x needs to be a value that makes g(x) = 5. You can set them up equal to each other 5 = 2x-3 and solve. You end up getting x = 4.
square root of 70 is
rational or iftationet
Answer:
Step-by-step explanation:
It's Irrational.
sqrt(70) = sqrt(2 * 5 * 7)
You can't pull anything out of the right to leave the number under the root sign = to 1. That means that since all three roots are irrational, the whole number is irrational, In fact it takes only 1 number other than 1 left under the root sign to make the result irrational.
√50 = √(5 * 5 * 2)
The 5's will produce one number outside the root sign -- five. That makes the result
5√2 The result is irrational because √2 is irrational
Here is a triangular prism.
Answer:
Volume of the prism: 120cm^3
Step-by-step explanation:
volume of a prism = area of cross-section x length
so
volume of triangular prism = 4 (h) x 6 (b) divided by 2 x 10 (length)
6 x 4 = 24
24 / 2 = 12
12 x 10 = 120

When calculating a loan’s effective interest rate, if the nominal rate is 8.5%, what value of i do you plug into your equation? a. 8.5 b. 0.85 c. 0.085 d. 1.85
The value of interest rate should be 0.085.
We have given that the interest rate is 8.5% So we have given in percentage form but we use always decimal form of interest.
What is the decimal form of percentage?
To convert a percentage to a decimal, divide by 100.
So the decimal form of the 8.5% is calculated by
[tex]\frac{8.5}{100}=0.085[/tex]
Therefore the option c is correct.
Therefore we use the interest rate is 0.085.

1.Solve for r in the scientific formula d= r t
2.Solve for V in the scientific formula P V= n R T
3. Solve for x in the literal equation [tex]\frac{x}{2}[/tex]-g= a
4. Solve for h in the literal equation g [tex](h+\frac{3}{2} )[/tex]=11
5. Solve for n in the literal equation a(n-2)+5=b n
Step-by-step explanation:
1. d = rt
Divide t from both sides.
[tex]\frac{d}{t} = r[/tex]
2. PV = nRT
Divide P from both sides.
[tex]V = \frac{nRT}{P}[/tex]
3. [tex]\frac{x}{2} -g=a\\[/tex]
Add g to both sides.
[tex]\frac{x}{2}[/tex] = g + a
Now multiply by 2 on both sides.
x = 2(g + a)
(or, x = 2g + 2a)
4. g[tex](h+\frac{3}{2} ) = 11[/tex]
Divide g from both sides.
[tex]h + 1.5 = \frac{11}{g}[/tex]
Now subtract 1.5 from both sides.
h = [tex]\frac{11}{g} -1.5[/tex]
