What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
3.5 + (1 + 4 x (6.5 + 1.5) )
= 3.5 + ( 5 x 8 )
= 3.5 + 40
= 43.5

Answer:
(b) 217 cm
Step-by-step explanation:
The computation of the number of centimeters will each have is shown below:
= Length of the string ÷ number of pieces
= 10.85 meters ÷ 5
= 2.17 meters
= 217 centimeters
hence, the correct option is b.

Answer:
8) ΔCAB ~ ΔFDE; SSS
9) ΔMNQ ~ ΔPNO; SAS
10) ΔDBE ~ ΔABC; SAS
Step-by-step explanation:
8) The side ratios, shortest to longest, are ...
6 : 8 : 10 = 9 : 12 : 15 = 3 : 4 : 5
so are the same for both triangles. Triangles CAB and FDE are similar by SSS.

What is the length of the missing leg?
Answer:
b = 24
explanation:
you use the Pythagorean theorem.
a^2 + b^2 =c^2
so we do 32^2 + x^2 = 40^2 then solve
32 squared is 1024 and 40 square is 1600 so you minus the 2 and get 576 then you square root 576 and you finally answer is 24

Answer:
x = - 6
Step-by-step explanation:
Equation
1/3 * (-9x +12) = 22 Multiply both sides by 3
Solution
3 * 1/3(-9x + 12) = 22*3
- 9x + 12 = 66 Subtract 12 from both sides.
-9x = 66 - 12 Combine
-9x = 54 Divide by -9
x = 54/-9

The points (0,3), (1,8), (2,17), and (3,30) are on the graph of a function. Which of the following equations represents that function?
a.2x^{2}-3x+3
b.2x^{2}+3x-3
c.2x^{2}-3x-3
d.2x^{2}+3x+3
Answer:
D. 2x^{2}+3x+3Step-by-step explanation:
Use the ordered pairs to determine the correct function
Point (0, 3)
x = 0 and y = 3- options A or D, the others result in y = -3Point (1, 8)
x = 1, y = 8 - option A.
2*1^2 - 3*1 + 3 = 2 - incorrectIt leaves us with option D
2*1^2 +3*1 + 3 = 8 - correctCheck other two pairs as well:
2*2^2 + 3*2 + 3 = 172*3^2 + 3*3 + 3 = 30This confirms option D is correct

Solve the simultaneous equations by substitution
3y - 2x = -7
5x + 3y = 28
Answer:
(5, 1 )
Step-by-step explanation:
Given the 2 equations
3y - 2x = - 7 → (1)
5x + 3y = 28 → (2)
Rearrange (1) expressing 3y in terms of x by adding 2x to both sides
3y = - 7 + 2x
Substitute 3y = - 7 + 2x into (2)
5x - 7 + 2x = 28
7x - 7 = 28 ( add 7 to both sides )
7x = 35 ( divide both sides by 7 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (2)
5(5) + 3y = 28
25 + 3y = 28 ( subtract 25 from both sides )
3y = 3 ( divide both sides by 3 )
y = 1
solution is (5, 1 )
Answer:
-(3y-2x= -7)
3y+5x= 28
-3y+2x= 7
3y+5x= 28
7x=35
7x/7= 35/7
x=5
5(5)+3y= 28
25+3y=28
3y= 28-25
3y=3
3y/3=3/3
y= 1
3y-2x= -7
3(1) -2x= -7
3-2x= -7
-2x= -7-3
-2x= -10

Gym membership costs $100 per year in a $2 fee per visit another gem charges $12 fee per visit with no yearly membership find the number of visits for which the charges for both gyms will be
Answer:
For 10 visits, both gyms charge the same
Step-by-step explanation:
Equations
Gym memberships' costs are:
G1 = 100 + 2x
G2 = 12x
Where x is the number of visits to the gym.
We need to find the number of visits for which the charges for both gyms are the same. Thus equating the costs:
12x = 100 + 2x
Subtracting 2x:
10x = 100
Dividing by 10:
x =10
For 10 visits, both gyms charge the same

Three angle are labeled below the acre. The smallest angle is 3/8 as large as the 160 angle. Find the value of angle a
Answer:
140°
Step-by-step explanation:
Three angle are labeled below the acre. The smallest angle is 3/8 as large as the 160 angle. Find the value of angle a
The value of the smallest angle is given as:
= 3/8 of the 160 angle
=3/8 × 160°
= 60°
The sum of the total angle = 360°
Hence:
360° = 60° + 160° + a
a = 360° - (60° + 160°)
a = 360° - 220°
a = 140°
Therefore, a = 140°

Find the fourth proportional of 3, 5, 6.
Answer:
10
Step-by-step explanation:
As I understand it, we are asking for 3/5 = 6/x, what is x?
You cross-multiplythe numerators and denominators.
3x = 30
x = 10
And 3 is to 5 as 6 is to 10.
In each case, the fraction = 0.6
The fourth proportion of 3: 5:: 6:__ is 10.
What is proportionality?In mathematics, proportionality denotes a linear relationship between two quantities or variables. Both quantities increase in size when one double, and both decrease in size when one drops to a tenth of its original value.
Given, the proportional of 3: 5:: 6: ___ To find the fourth proportional
Let x be the fourth proportional.
Thus,
[tex]\frac{3}{5} = \frac{6}{x}[/tex]
x = (5*6)/3
x = 5*2 = 10
