Answer:
No
Step-by-step explanation:
We can't use 2x + c = d for solving 2x + 1 = 9 . Here we can find the value of x from 2x + 1 = 9.

Putting the value of x in 2x + c = d :-

But still we don't know the exact value of c & d . If in the question at least we could have got one exact value of either c or d , then we could find out the value of other variable.
Answer:
43/9
Step-by-step explanation:
Step 1
Multiply the denominator by the whole number
9 × 4 = 36
Step 2
Add the answer from Step 1 to the numerator
36 + 7 = 43
Step 3
Write answer from Step 2 over the denominator
43/9
=439
Answer:
x=5
Step-by-step explanation:
Hello!
1/2 = 0.5 as a decimal
0.5 ÷ 2 = 0.25
That means you walk 1 mile in 0.25 of an hour. Multiply this by three:
0.25 × 3 = 0.75
Answer:
It will take you 0.75 (or 3/4) hour to walk 3 miles.
Answer:
x=70
Step-by-step explanation:
when added together, verticle angles equal 180 degrees.
2x-10+x+20=180
3x-10+20=180
3x-30=180
3x=210
x=70
