Answer:

g =1.356207187

Step-by-step explanation:

7^g =14

Take the log on both sides

log (7^g) = log 14

We know that log a^b = b log a

g log 7 = log 14

Divide each side by log 7

g log 7 /log 7 = log 14 / log 7

g = log 14 / log 7

g =1.356207187

Answer:

g = 1.356

Step-by-step explanation:

Use logs both sides

log(7^g) = log(7×2)

glog7 = log7 + log2

g = 1 + log2/log7

g = 1.3562071871

Roger has 7 dimes and 17 pennies. The total amount of money Roger has, in dollars, can be found by evaluating 7/10 + 17/100. Whi

stepan [7]

If you want to add fractions, you need to first make them like fractions, this means both fractions need to have the same denominator without changing its proportion:

7/10 = 70/100
17/100 = 17/100

Now it is the same and you can add them now because they are like fractions.

70/100 + 17/100 = 87/100

Your answer is B.

2x+y=5 , 3x+2y=8 solve using cross multiplication

Xelga [282]

Answer:

x=2

y=1

Step-by-step explanation:

2x+y=5

3x+2y= 8

<=> 6x+3y=15

6x+4y=16

<=> -y=-1

2x+y=5

<=> y=1

2x+1=5

<=> y=1

2x=4

<=> y=1

x=2

Drag each part of the equation to categories it as a term or a coefficient in the expression. Parts that are neither a term nor

faust18 [17]

Answer:

In the given expression:

Term = $x , x$

Coefficient= $-2, (\frac{3}{4})$

Neither one = 5

Step-by-step explanation:

Here, the given expression is : $-2x+\frac{3}{4} x +5$

Now, in the polynomial of the form $ax^{2} + bx + c$

All the x terms involving any powers of x are 'TERM'

Like $x^{2} , x$

All the co efficient of the x in the polynomial are called 'Co -efficient.

Here, a , b are co efficient.

The terms in the polynomial which are neither coefficient nor terms are called 'Constants' . Here, c is constant.

Now, in the given expression:

Term = $x , x$

Coefficient= $-2, (\frac{3}{4})$

Neither one = 5
