Answer:
x= 0.5
or x= -1.5
Step-by-step explanation:
Let's solve your equation step-by-step.
4x2+4x−3=0
Step 1: Factor left side of equation.
(2x−1)(2x+3)=0
Step 2: Set factors equal to 0.
2x−1=0 or 2x+3=0
x= 1/2 or x= −3/2
Given that,
The length of ribbon= 36 inch
We know, if Shelia wants to divide the ribbon in 5 equal parts, she needs to divide the length of the ribbon by 5.
So,
The length of the 5 equal parts of the ribbon= 36/5= 7.2 inch
But Shelia got each pieces length equals to 7 inches.
So, There is an error of (7.2-7) 0.2 inches in her calculation.
Answer:
Dividing by 1 gives a quotient equal to the dividend. When the divisor is less than 1, the quotient is <em><u>larger</u></em> than the dividend. Decreasing the divisor to 1/2 increases the quotient to 10 1/2 When the divisor is smaller than the dividend, the quotient is more than 1.
Answer:
38.4;
Step-by-step explanation:
32.5% × ? = 12.48
? =
12.48 ÷ 32.5% =
12.48 ÷ (32.5 ÷ 100) =
(100 × 12.48) ÷ 32.5 =
1,248 ÷ 32.5 =
38.4;
