1/2x+3/2(x+1)-1/4=5
1 answer:
Answer: x=15/8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1/2 x+(3/2)(x)+ (3/2)(1) + −1/4 =5(Distribute)
Then, Combine like terms:
(1/2x + 3/2x) +(3/2 + −1/4) =5(Combine Like Terms)
Which you will get : 2x+ 5/4 =5
Step 2: Subtract 5/4 from both sides.
2x+ 5/4 − 5/4 =5− 5/4
2x= 15/4
Step 3: Divide both sides by 2.

Answer:
B) 8
Step-by-step explanation:
In this question, KLMN ~ PQRS. This means they are similar shapes.
From the image, we could denote that:
KL ~ PQ
LM ~ QR
Given that:
KL = 12
PQ = 30
QR = 20
LM = x
To find x, let's use tge expression:
Cross multiplying, we have:
12 * 20 = 30x
240 = 30x
To find x, let's divide both sides by 30.
8 = x
x = 8
The correct option is option B.
