I believe what you would do is multiply $20 by 8% and get 1.6. So ten you would subtract 1.6 from 20 and get $18.40 on the book.

Solve for (g).<br><br> −3+5+6g=11−3g<br><br> g= ?
Zina [86]

Answer:

g=1

Step-by-step explanation:

Given equation is \[−3+5+6g=11−3g\]

Simplifying, \[2+6g=11−3g\]

Bringing all the terms containing g to the left hand side and the numeric terms to the right hand side,

\[6g + 3g=11−2\]

=> \[(6 + 3)g=9\]

In other words, \[g=\frac{9}{9}\]

Or, g = 1

The given equation is satisfied for g=1.

Validation:

Left hand side of the equation: -3+5+6 = 8

Right hand side of the equation: 11-3 = 8

Drag each equation to show if it could be a correct first step to solving the equation 3(x+8)=42.
jeyben [28]

Answer:

3*x + 3*8 = 42 simplified as 3x + 24 = 42

Step-by-step explanation:

The correct first step in solving the equation is to apply the distributive property. Order of operations states to perform operations in this order, PEMDAS, left to right. Some operations can be applied at the same time left to right through the equation such as multiplication and division as well as addition and subtraction. Since 3 is being multiplied into parenthesis, this needs to be applied first using the distributive property.

3(x+8)=42

3*x + 3*8 = 42

3x + 24 = 42

You can continue to solve using inverse operations.

3x = 18

x = 6

ikadub [295]

Answer:

This equation is in standard form: ax 1+bx+c=0. Substitute 9 for a, 16 for b, and −112 for c in the quadratic formula 2a−b±b2−4ac.x= 2×9−16± 16^2−4×9(−112)Square 16.x=2×9−16±256−4×9(−112) Multiply −4 times 9.x=2×9−16± 256−36(−112) Multiply −36 times −112.x=2×9−16±256+4032 Add 256 to 4032.x=2×9−16±4288 Take the square root of 4288.x=2×9−16±8+67 Multiply 2 times 9x=18−16±8=67
