Answer:
34.41
Step-by-step explanation:
Using the Pythagorean Theorem:
a^2 + b^2 = c^2
20^2 + 28^2 = c^2
400 + 784 = c^2
1,184 = c^2
sqrt(1,184) = c
34.41 = c
Answer:
x= -1
Step-by-step explanation:
open brackets and calculate
3x - 12 + 6 = 5x -5 + 1
Calculate
3x - 6 = 5x - 4
transpose
3x - 5x = - 4 + 6
Calculate
- 2x = 2
x= 2/-2
x= -1
Answer:
X = -1
Step-by-step explanation:
3(x - 4) + 6 = 5(x - 1) + 1 -distribute
3x - 12 + 6 = 5x - 5 + 1 -combine like terms
3x - 6 = 5x - 4 -subtract 3x
-6 = 2x - 4 -add 4
-2 = 2x -divide by 2
-1 = x
Hope this helps. Pls give brainliest.

Same with the other question we did, we are given the area of each tile which is 4 1/2in^2.
All we need to do it divide.
252 / 4.5 = 56
So, she would need 56 tiles in total.
Best of Luck!
Answer:
56 tiles
Step-by-step explanation:
Hope this helps!
4x - y = 7
2) 2x - 3y = 12
x = 4y + 1
3) y = 5 - x
x - 4y = 10
