3 - x = 10
-x = 10 - 3
-x = 7
x = -7 <===
Answer:
Equation: 7x - 23 = 25 + x
Solution: x = 8
Step-by-step explanation:
7x - 23 = 25 + x
1. Subtract 25 from both sides:
7x - 23 - 25 = 25 - 25 + x
7x - 48 = x
2. Subtract 7x from both sides to get x on one side:
7x - 7x - 48 = x - 7x
- 48 = -6x
3. Divide both sides by -6 to get x by itself:
8 = x
8 is the solution

Answer:
1 1/3
Step-by-step explanation:
1/3 divided by 1/4
keep change flip so 1/3 times 4/1 multiply straight across
Answer:
The lengths of the sides are 15 cm , 17 cm and 19 cm.
Step-by-step explanation:
Step 1. Perimeter P means adding up all three sides.
Step 2. Let n be an odd integer.
Step 3. Let n+2 and n+4 be the next two consecutive odd integers.
Step 4. Then P=n+n+2+n+4=51.
Step 5. Solving the equation Step 4 yields the following steps
3n%2B6=51
Subtract 6 from both sides of the equation
3n%2B6-6=51-6
3n=45
Divide 45 to both sides of the equation
3n%2F3=45%2F3
n=15 Then n%2B2=17 and n%2B4=19. Also, P=15+17+19=51 which is a true statement.
Step 6. ANSWER: The lengths of the sides are 15 cm , 17 cm and 19 cm.
