Answer:
Cody has solved (12 × 12) = 144 problems.
Step-by-step explanation:
For every one problem that Julia completes, Cody completes twelve.
If Julia Completes x problems and Cody completes y problems, then we can write y = 12x ........ (1)
Now, given that the number of problems solved by Cody is one hundred twenty more than two times the number of problems solved by Julia.
Hence, 2x + 120 = y ......... (2)
Now, from equations (1) and (2) we get,
2x + 120 = 12x
⇒ 10x = 120
⇒ x = 12
Therefore, Cody has solved (12 × 12) = 144 problems. (Answer)
Answer:
x = -30
Step-by-step explanation:
g(x)= -2/3x+5
Let g(x) = 25
25= -2/3x+5
Subtract 5 from each side
25-5= -2/3x+5-5
20 = -2/3x
Multiply each side by -3/2
-3/2 * 20 = -3/2 * -2/3 x
-30 = x
Answer:
Step-by-step explanation:
Let c ----> Cat
t ------> Table
f ---------> Frog
From the first figure,
c + t -f = 170 -----------(i)
From the second figure,
f + t -c = 130 ---------(ii)
Add (i) and (ii)
(i) c + t -f = 170
(ii) <u>f + t -c = 130</u> {c & -c and f & -f gets cancelled
2t = 300
t = 300/2
t = 150 cm
The table is 150 cm tall
