Answer:
the answer is 50
Step-by-step explanation:
first you want to get the 54 off so you subtract it form both sides and get 1v=50 and then you want to get 1 off so you dived and get v=50. thats strange
8. True or false: in order to solve the following equation, you would first subtract by 4, then multiply by 5/1 *
4+1/5=-1
To solve 3x + 2 = 23 you must:
Subtract 2 from both sides so like this 3x+2−2=23−2 and get 3x=21.
Now Divide both sides by 3 so 3x/3=21/3. Mainly divide 21/3 and get 7.
--------------------------------------------------------------------------------
To solve -2y - 7 = 3 you must:
Add 7 to both sides so like this −2y−7+7=3+7 and get −2y=10.
Now Divide both sides by -2 so -2y/-2=10/-2. Mainly divide 10/-2 and get 5.

False
Answer:
- 17
Step-by-step explanation:
hello :
5x + 25(34-x)= 510
divid by 5 : x +5(34-x)=102
x+ 170 -5x = 102
-4x =102-170
-4x = 68
x = 68/- 4 = - 17
mm
Answer:
It will measure 75 millimetres on the plan.
Step-by-step explanation:
Given:
Scale on the plan = 1:100
Length of the fence = 7,500 mm
To find:
how many millimetres will it measure on the plan
Solution:
As the ratio on the plan is 1: 100, the for 7500 the ratio will
x : 7500
Now by cross multiplication we get
x = 75
