Answer:

x = -4

Step-by-step explanation:

2x + 4(2x+7) = 3(2x+4)

distributive property first

2x + 8x + 28 = 6x + 12

now combine like terms

10x + 28 = 6x + 12

now move the +28 over to the other side by subtraction

10x = 6x -16

move the 6x over by subtraction

4x = -16

divide by 4

x = -4

Evaluate 2.6 raised to the seventh power divided by 2.6 raised to the sixth power, all raised to the second power.

igomit [66]

The evaluation of 2.6 raised to the seventh power divided by 2.6 raised to the sixth power, all raised to the second power is as follows:

$(\frac{2.6^{7} }{2.6^{6} } )^{2} = 6.76$

<h3>How to evaluate an expression?</h3>

2.6 raised to the seventh power divided by 2.6 raised to the sixth power, all raised to the second power.

The following expression can be evaluated as follows;

$(\frac{2.6^{7} }{2.6^{6} } )^{2}$

Using the law of indices,

$(A^{x} )^{y} = A^{xy}$

Therefore,

$(\frac{2.6^{7} }{2.6^{6} } )^{2} = (\frac{2.6^{14} }{2.6^{12} } )$

Using the law of indices,

$\frac{A^{x} }{B^{y} } = A^{x-y}$

Hence,

$(\frac{2.6^{7} }{2.6^{6} } )^{2} = (\frac{2.6^{14} }{2.6^{12} } ) = 2.6^{14-12} = 2.6^{2} = 6.76$

Therefore,

$(\frac{2.6^{7} }{2.6^{6} } )^{2} = 6.76$

The evaluation of 2.6 raised to the seventh power divided by 2.6 raised to the sixth power, all raised to the second power is 6.76.

A jeweler is dividing

tatuchka [14]

Question:

A jeweler is dividing 3/8 of a pound of rubies among 4 lots. What part of a pound will each lot weigh? A.1/4 B.1/8 C.1/16 D.3/32

Answer:

Option D

Each lot weight $\frac{3}{32}$ part of pound

Solution:

Given that,

A jeweler is dividing 3/8 of a pound of rubies among 4 lots

To find: part of a pound each lot weigh

From given,

$\frac{3}{8} \text{ of a pound } = 4 lots$

Let "x" be the part of a pound each lot weigh

Therefore,

$\frac{3}{8} \text{ of a pound } = 4 lots\\\\"x" part = 1\ lots$

This forms a proportion and solve by cross multiplying

$\frac{3}{8} \times 1 = 4 \times x\\\\x = \frac{3}{32}$

Thus, each lot weight $\frac{3}{32}$ part of pound

Mr McKay bought b boxes of crackers for $3 each and p pounds of cheese for $4 per pound. How much did he spend in all.

malfutka [58]

In normal circumstances, you would multiply the amount of boxes by 3, and the amount of pounds by 4. So you do the same here:
3b + 4p

Mr McKay spent 3b + 4b in total
