Answer:
26.411
Step-by-step explanation:
Given that:
3a + bc - c
when;
a = 8.6
b = 2.3
c = 0.47
Then;
= 3(8.6) + (2.3)(0.47) - 0.47
Open brackets
= 25.8 + 1.081 - 0.47
= 26.411

On tuesday there were 23 students absent from school. The total number of students at school that day was 372 students. How many students attend the school.
Answer: The number of students attend the school = 349
Step-by-step explanation:
Given: Number of students absent on Tuesday = 23
Total number of students = 372
Number of students attend the school that day = (total students) - (Number of students absent )
= 372-23
= 349
Hence, the number of students attend the school that day = 349

On the following Monday, his hits double that of the week before. Write and evaluate a numerical expression to find how many times he hit the target during those three weeks.
Answer:
in all he hit the target 50 times
Step-by-step explanation:
first week he hits 5
second week hits 15=5x3
third week hits 30=15x2
The number of times he hit the target in three weeks is 50.
Definition of a numerical expressionA numerical expression is a mathematical statement that consist of integers joined together by operation symbols. Examples of operation symbols are addition, subtraction, multiplication and division. An example of a numerical expression is 5 + 3.
Numerical expressions that represent the number of times the ball was hitNumber of times the ball hit the target in the first week = 5 times Number of times the ball hit the target in the second week = 5 x 3 = 15 Number of times the ball hit the target in the third week = 15 x 2 = 30Total sum = 30 + 15 + 5 = 50 times

The price of a cell phone was marked down by $35. The original price of the cell phone was $212. What was the percentage rate of the discount
Given:
The price of a cell phone was marked down by $35.
The original price of the cell phone was $212.
To find:
The percentage rate of the discount.
Solution:
We have,
Price marked down by= $35
Original price = $212
Now, the percentage rate of the discount is
[tex]Discount\%=\dfrac{\text{Price marked down by}}{\text{Original price}}\times 100[/tex]
[tex]Discount\%=\dfrac{35}{212}\times 100[/tex]
[tex]Discount\%=\dfrac{3500}{212}[/tex]
[tex]Discount\%=16.509434[/tex]
[tex]Discount\%\approx 16.51[/tex]
Therefore, the rate of discount in percentage is 16.51%.

3. Solve this equation. Does the equation have one solution, no solution, or
infinitely many solutions? 8(3x - 6) = 6(4x + 8) *
One solution
No solution
Infinitely many solutions
Answer:
no solution
Step-by-step explanation:
Given
8(3x - 6) = 6(4x + 8) ← distribute both sides
24x - 48 = 24x + 48 ( add 48 to both sides )
24x = 24x + 96 ( subtract 24x from both sides )
0 = 96 ← not possible
This indicates the equation has no solution
