Answer:
x = 14
Step-by-step explanation:
4x° + (3x + 20)° + (3x + 20)° = 180° (sum of interior angles; isocleces triangle)
10x + 40 = 180
10x = 140
x = 14
The answer is 882 because if you divide 882 by 9 you get 98 and 98 time 9 is equal to 882 so therefore 882 is divisible by 9
Answer:
(3,2)
Step-by-step explanation:
2x+3y=12
substitute x with 3 because x=3
2(3)+3y=12
multiply
6+3y=12
(subtract 6 from both sides)
3y=6
(divide by 3 on both sides)
1y=2
x = 3 and y = 2
4/(5+3/x)= 1/2 t 8 = 5 +3/x 8x = 5x + 3 or x = 1
i do not confirm that this is correct by the way
Answer:
A. (0,445)
D.(118,209)
E.(172,101)
Step-by-step explanation:
The equation that we have in this problem is:
where
d is the number of dimes
n is the number of nickels
$22.25 is the total amount of money collected by Diego in the jar.
In order to find which pairs of values can be solutions to the equation, we just need to substitute each pair (d,n) into the left term on the equation, and check if the result is 22.25. Let's do it:
A. (0,445)
--> YES
B. (0.50,435)
--> NO
C. (233,21)
--> NO
D.(118,209)
--> YES
E.(172,101)
--> YES
So the correct pairs are:
A. (0,445)
D.(118,209)
E.(172,101)
