Answer:

The answer should be 23.

Step-by-step explanation:

If C=7, then you just need to plug 7 into the equation.

5(6) - 7

From there, you just need to multiply 5 times 6 which is 30. After that you have 30-7 which gets you 23.

The combined area of two squares is 45 square centimeters.each side of one square is twice as long as the side of the other .wha
serg [7]
Formula of square area
a = s²
thus, area of the first square could be written as s₁² and area of the second square could be written as s₂²

First, write an expression in the form of equation system
An expression for "The combined area of two squares is 45 square centimeters" is:
⇒ s₁² + s₂² = 45 <em>(first equation)</em>
An expression for "Each side of one square is twice as long as side of the other" is:
⇒ s₁ = 2s₂ <em>(second equation)</em>

Second, solve the equation system by substitution method.
⇒ We could substitute 2s₂ to s₁ (second equation) in the first equation in order to find the value of s₂
s₁² + s₂² = 45
(2s₂)² + s₂² = 45
(2²)(s₂)² + s₂² = 45
4s₂² + s₂² = 45
5s₂² = 45
s₂² = 45/5
s₂² = 9
s₂² = 3²
s₂ = 3

⇒ Substitute the value of s₂ to the second equation in order to find the value of s₁
s₁ = 2s₂
s₁ = 2(3)
s₁ = 6

The length of each side of the larger square is 6 centimeters

Alex73 [517]
We need to build a system of equations:

a + b + c = 127......(1)
b  - c = 13..............(2)
a - b - c = 41..........(3)

adding equations (1) and (3):-

2a = 168
a = 84   
Substituting for in equation (1)-
84 + b + c = 127
b   + c = 43...........(4)
Adding equations (2) and (4):-
2b = 56 

b = 28
Finally from equation (2)
c = 28-13 = 15

Answer is Country a had 84 points , b had 28 points and c had 15 points.

What is the volume of the prism with a base of 6 height of 5 and lenght of 10
Tanzania [10]
\sf Hello!

\sf Dimensions\: of \:the \:Prism :

• \sf Base,\: b = 6
• \sf Height, \:h = 5
• \sf Height, \:H = 10

\sf Then,

\sf Volume \:of \:Prism :

= \dfrac {\sf 1}{\sf 2} × \sf b × \sf h × \sf H

= \dfrac {\sf 1}{\sf 2} × \sf 6 × \sf 5 × \sf 10

= \sf 6 × 5 × 5

= \sf 150

\sf Hence,
\sf The\: volume\: of \: the\: prism\: is \:150\: cubic\: units.
