Answer:
[tex]B = 69[/tex]
Step-by-step explanation:
Given
[tex]A = 2x +27[/tex]
[tex]B = x +27[/tex]
Required
Determine B
First, we need to solve for x
Since both angles are supplementary, then
[tex]A + B = 180[/tex]
Substitute values for A and B
[tex]2x + 27 + x + 27 = 180[/tex]
Collect Like Terms
[tex]2x + x = 180 - 27 - 27[/tex]
[tex]3x= 126[/tex]
Divide through by 3
[tex]x = 42[/tex]
Recall that:
[tex]B = x +27[/tex]
Substitute 42 for x
[tex]B = 42 + 27[/tex]
[tex]B = 69[/tex]

Q1 a) Kamahi invests some money which earns compound interest every year. His investment
amounts to sh60, 500 at the end of the second year and sh 73,205 at the end of the fourth year. Find
the rate of interest of the investment.
(5 marks)
Answer: 2=2
Step-by-step explanation:
Without any more information, it sounds like interest is compounded continuously, in which case the value of the investment A is given by
[tex]A=Pe^{rt}[/tex]
where P is the principal investment, r is the interest rate, and t is the number of years.
At the end of the second year (t = 2), the value is A = 60,500, and after the fourth year (t = 4), the value is A = 73,205. So solve the system
[tex]\begin{cases}60,500=Pe^{2r}\\73,205=Pe^{4r}\end{cases}[/tex]
for r. You can eliminate P by dividing
[tex]\dfrac{Pe^{4r}}{Pe^{2r}}=\dfrac{73,205}{60,500}\implies e^{2r}=\dfrac{121}{100}[/tex]
Take the logarithm (log here means natural log) of both sides to get
2r = log(121/100)
r = 1/2 log(121/100)
r ≈ 0.0953
So the interest rate is about 9.53%.

[tex]\huge\boxed{\sf k = 2}[/tex]
Step-by-step explanation:
Coordinate = (x,y) = (2k-1,k)
This means that:
x = 2k - 1 and y = k
Put it in the given equation: 5x - 4y = 7
5(2k-1) - 4k = 7
10k - 5 - 4k = 7
6k - 5 = 7
Adding 5 to both sides
6k = 7+5
6k = 12
Divide both sides by 6
k = 2

Solve the equation -3=6x-3y for y
Answer:
y = 2x + 1
Step-by-step explanation:
-3 = 6x - 3y
Add 3y to both sides.
3y - 3 = 6x
Add 3 to both sides.
3y = 6x + 3
Divide both sides by 3.
y = 2x + 1

khloe and her children went into a movie theater where they sell bags of popcorn for $7 each and candies for $4 each. khope has $60 and must buy no less than 11 bags of popcorn and candies altogether. if x represents the number of bags of popcorn purchased and y represents the number of candies pruchased, write and solve a system of inequalities and determine one possible solution
both inequalities must start with y
Answer: Khloe could buy 3 bags of popcorn and 9 candies.
Step-by-step explanation:
\underline{\text{Variable Definitions:}}
Variable Definitions:
x=
x=
\,\,\text{the number of bags of popcorn}
the number of bags of popcorn
y=
y=
\,\,\text{the number of candies}
the number of candies
\text{\textquotedblleft no less than 11 items"}\rightarrow \text{11 or more items}
“no less than 11 items"→11 or more items
Use a \ge≥ symbol
Therefore the total number of bags of popcorn and candies, x+yx+y, must be greater than or equal to 11:11:
x+y\ge 11
x+y≥11
\text{\textquotedblleft \$60 to spend"}\rightarrow \text{can spend \$60 or less}
“$60 to spend"→can spend $60 or less
Use a \le≤ symbol
One bag of popcorn costs $7, so xx bags of popcorn cost 7x.7x. One candy costs $4, so yy candies cost 4y.4y. The total 7x+4y7x+4y must be less than or equal to \$60:$60:
7x+4y\le 60
7x+4y≤60
\text{Solve each inequality for }y\text{:}
Solve each inequality for y:
\begin{aligned}x+y\ge 11\hspace{30px}& 7x+4y\le 60 \\[0.8em] y\ge 11-x \hspace{30px}& 4y\le 60-7x \\[0.8em] \hspace{30px}& y\le \frac{60-7x}{4} \\[0.8em] & y\le 15-\frac{7}{4}x\end{aligned}
x+y≥11
y≥11−x
7x+4y≤60
4y≤60−7x
y≤

y≤15−

x by shading down:

the number of candies
x
y
0
the number of bags of popcorn
the number of candies
(3, 9)
Since the point (3, 9(3,9) is inside the double shaded region, one possible solution to the system of inequalities would be:
Khloe could buy 3 bags of popcorn and 9 candies.
The system of inequalities are x + y ≥ 11 and 7x + 4y ≤ 60 and the solution is given by the point P ( 3 , 9 ) where x represents the number of bags of popcorn purchased and y represents the number of candies purchased
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let x represents the number of bags of popcorn purchased and y represents the number of candies purchased
Now , the total number of bags should be no less than 11
And , the inequality is
x + y ≥ 11 be equation (1)
And , cost of each popcorn bag = $ 7
So , the cost of x bags = 7x
And , cost of each candy bag = $ 4
So , the cost of y bags = 4y
The total amount with Khloe = $ 60
And , the inequality is
7x + 4y ≤ 60 be equation (2)
On graphing the inequalities , we can see that the point P ( 3 , 9 ) lies inside the solution
So , 7 ( 3 ) + 4 ( 9 ) ≤ 60
21 + 36 ≤ 60
57 ≤ 60
And , 3 + 9 ≥ 11
12 ≥ 11
Hence , the system of inequalities are solved and the graph is plotted

Rani ate 2/7 of the cake while her brother ate 4/5 part of the remaining. part of the cake left is?
Answer:
Nothing left
Step-by-step explanation:
Nothing left
2/7+4/5=38/35
1 3/35
Answer:
[tex]\frac{1}{7}[/tex]
Step-by-step explanation:
Amount of cake Rani ate = [tex]\frac{2}{7}[/tex]
You need to understand that her brother ate 4/5 of the remaining part, not of the entire cake, so we need to figure out the actual amount out of the entire cake first before calculating how much is left.
Amount of cake brother ate = [tex]\frac{4}{5}[/tex] × ([tex]\frac{7}{7}[/tex] - [tex]\frac{2}{7}[/tex])
= [tex]\frac{4}{5}[/tex] × [tex]\frac{5}{7}[/tex]
= [tex]\frac{4}{7}[/tex]
Amount of cake left = [tex]\frac{7}{7}[/tex] - [tex]\frac{2}{7}[/tex] - [tex]\frac{4}{7}[/tex]
= [tex]\frac{1}{7}[/tex]

By using the substitution method we can prove s = 2r.
Given,
2p - r = p
r = q - s
p = q + 2r
We need to prove s = 2r.
What is a substitution method?It is a method where we substitute the value of one variable in one equation for the same variable in the other equation.
Example:
x + 4 = y _____(1)
x = y - 4
x + 5 = 2y ______(2)
Putting x = y - 4 in (2)
y - 4 + 5 = 2y
-4 + 5 = 2y - y
1 = y
y = 1
Prove s = 2r.
We have,
2q - r = p ____(1)
r = q - s _____(2)
p = q + 2r ______(3)
From (1) and (2)
Substituting (2) in (1)
2q - (q - s) = p
2q - q + s = p
q + s = p _____(4)
Putting (4) in (3)
q + s = q + 2r
q - q + s = 2r
s = 2r
Hence proved.
Thus we can prove s = 2r.
