Hello Dafnemlp47vj7
The inequality for one week would be <u><em>13 = 2c + 3 </em></u>
Answer:
first blank is "rhombus"
second blank is "rectangle"
third blank is "are congruent"
Step-by-step explanation:
I read this story last year for my 7th grade year. The correct answer is A!
To find the area of the circle, you will use the formula for finding area of any circle.
The radius is half the diameter.
A = pi x r^2
3.14 x 13^2
A = 530.66 square units
The area is 530.66 square units.
Answer:
This system has infinite solutions and it would be much easier to solve it by elimination but substitution it is.
Step-by-step explanation:
-3x+3y=9
-x+y=3
Isolate either x or y in any of the equations. I'll go with the second.
y = 3+x
Now substitute this for y in the first equation.
-3x+3(3+x)=9
Distribute the 3
-3x+9+3x=9
Combine like terms:
9=9
0=0
It's infinite
