How do you simplify 50 1/2+ -12.3

levacccp [35]

50 1/2 = 50.5

50.5 + -12.3

When adding a negative number to a positive number, it basically becomes just subtraction so 50.5 + -12.3 means 50.5 - 12.3

50.5 - 12.3 = 38.2

Solve using the quadratic frmula 2x^2-5x=3

Mnenie [13.5K]

2x2−5x=3

I think the first step would be to

Subtract 3 from both sides

2x2−5x−3=3−3

2x2−5x−3=0

Then

For this equation: a=2, b=-5, c=-3

2x2+−5x+−3=0

Lastly you would

Use quadratic formula with a=2, b=-5, c=-3

I think your answer would then have to be...

x = 3 or x = −1 /2

Addy bought a new shirt and she had a 20% off coupon . The coupon took $8.25 off of the price of her shirt. What did she pay wit

zloy xaker [14]

Answer:

$33

Step-by-step explanation:

Given: Addy had 20% off coupon.

The coupon took $8.25 off of the shirt price.

Lets assume the original cost of shirt be "x".

We know Addy had 20% off coupon, which help to reduce the price of shirt by $8.25.

∴ We can form an equation to know the original price of shirt.

⇒ $\frac{20}{100} \times x= \$ 8.25$

⇒ $\frac{1}{5} \times x= \$ 8.25$

Multiplying both side by 5

⇒ $x= 8.25\times 5$

∴ $x= \$ 41.25$

Hence, The original cost price of shirt was $41.25.

Next, finding the price paid by Addy for her new shirt by reducing coupon discount from the cost of shirt.

Price paid by Addy for her new shirt= $\$ 41.25- \$ 8.25= \$ 33$

Hence, Addy paid $33 for her new shirt.

kolezko [41]

Wesley will need 10 10-inch stones, and 9 5-inch stones.

Since he wants to begin and end the pattern with 10-inch stones, we put a 10 at the beginning and end.

10 5 10 5 10 5 10 5 10 5 10 5 10 5 10 5 10 5 10

10 x 10-inch = 100 inches
9 x 5-inch = 45 inches

100 + 45 = 145 inches
