Amaka buys 4 rulers and a pencil and these cost the same as 2 rulers and 4 pencils. If a pencil cost #8, how much does a ruler cost?
Answer: ruler cost $12
Step-by-step explanation:
step 1
Let cost of ruler be represented as r
and cost of pencil be represented as p
we were given that
4 rulers and a pencil and these cost the same as 2 rulers and 4 pencils which is expressed as
4r + p = 2r+ 4p
and cost of pencil= $8
therefore
sTEP 2--- Solving
4r+ 8 = 2r+ 4 x8
4r+ 8 = 2r+ 32
4r - 2r= 32-8
2r= 24
r= 24/2 = r= $12

If -3x + 5 > 4, which of the following cannot be a value of x? 7.11B-S)
A -3
B -1
C о
D 4
Answer:
D
Step-by-step explanation:
Solving the inequality
- 3x + 5 > 4 ( subtract 5 from both sides )
- 3x > - 1
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative value.
x < [tex]\frac{1}{3}[/tex]
The only value not less than [tex]\frac{1}{3}[/tex] is 4 → D

The measure of one angle is thirteen less than five times the measure of another angle. The sum of the measures of the two angles is 140°. Determine the measure of each angle in degrees.
Answer:
The two angles are 25.5 and 114.5
Step-by-step explanation:
x = measure of one angle
5x - 13 = measure of the other angle {one angle is 13 less than 5 times the other}
x + 5x - 13 = 140 {sum of the two angles is 140}
6x - 13 = 140 {combined like terms}
6x = 153 {added 13 to each side}
x = 25.5 {divided each side by 6}
5x - 13 = 114.5 {substituted 25.5, in for x, into 5x - 13}

Just carpet has eight different quality grades of carpeting. Three types are being selected for a corporate test on durability. how many different samples of size 3 can be taken without replacement? how many different samples of size 5 can be taken without replacement?
Answer:
When we have a set of N elements, the number of combinations of K elements (such that N ≤ K) from these N elements is:
[tex]C(N, K) = \frac{N!}{(N - K)!*K!}[/tex]
Then if we have 8 different types of carpet, and we want to see how many different samples of 3 types we can choose, we just need to replace N by 8, and K by 3 in the above equation:
[tex]C(8, 3) = \frac{8!}{(8 - 3)!*3!} = \frac{8!}{5!*3!} = \frac{8*7*6}{3*2} = 56[/tex]
So there are 56 different samples.
Now we can do the same, but this time we want to use 5 types of carpet, then we will have K = 5.
[tex]C(8, 5) = \frac{8!}{(8 - 5)!*5!} = \frac{8!}{3!*5!} = 56[/tex]
Again, we have 56 different samples.
Evaluate the expression 6x+8 when x=2

\text{From these equations we can see}\\ \\ (9x-15)^2=(7x+5)^2\\ \\ 9x-15=7x+5\\ \\ 2x=20\\ \\ x=10[/tex]
A shoe sales associate earned $300 in November. In December she earned 8% more than she did in November. How much she earn in December? *
Answer:
$324.00
Step-by-step explanation:
Increase the number by 8% of its value.
Percentage increase = 8% × 300
New value =
300 + Percentage increase =
300 + (8% × 300) =
300 + 8% × 300 =
(1 + 8%) × 300 =
(100% + 8%) × 300 =
108% × 300 =
108 ÷ 100 × 300 =
108 × 300 ÷ 100 =
32,400 ÷ 100 =
324
$24.. 8% of $300 equals 24 so the associate made $324 dollars in December. 24+300=324

Step-by-step explanation:
We are given that
[tex]5\frac{1}{3}+(-4\frac{1}{6})+(-2\frac{1}{2})[/tex]
We have to find the value of given expression
[tex]\frac{5(3)+1}{3}-(\frac{4(6)+1}{6})-(\frac{2(2)+1}{2})[/tex]
[tex]=\frac{15+1}{3}-\frac{24+1}{6}-\frac{4+1}{2}[/tex]
[tex]=\frac{16}{3}-\frac{25}{6}-\frac{5}{2}[/tex]
LCM(2,3,6)=6
[tex]=\frac{32-25-15}{6}[/tex]
