74% means 0.74
"of" means "times"

So, 128 = 0.74 times (the number)

Divide each side of this equation by 0.74 :

128/0.74 = the number

172.973 (rounded) = the number

10% of what number is 10?

yarga [219]

Answer:

100

Step-by-step explanation:

10 is 10% of X

Equation: Y = P% * X

Solving our equation for X

X = Y/P%

X = 10/10%

Converting percent to decimal:

p = 10%/100 = 0.1

X = 10/0.1

X = 100

If a customer uses 80 MB, the monthly cost will be $19.00. If the customer uses MB, the monthly cost will be $. Find a linear eq

CaHeK987 [17]

Answer:

$c = 4.211\cdot n$

Step-by-step explanation:

The linear equation has the following form:

$c = \frac{\Delta C}{\Delta n} \cdot n$

Where:

$n$ - Number of MBs of the data plan.

$c$ - Monthly cost of the data plan.

The slope of the function is:

$\frac{\Delta C}{\Delta n} = \frac{c}{n}$

$\frac{\Delta C}{\Delta n} = \frac{80\,MB}{19\,USD}$

$\frac{\Delta C}{\Delta n} = 4.211\,\frac{MB}{USD}$

The equation is:

$c = 4.211\cdot n$

I need to figure out what x is

Svet_ta [14]

For all triangles, the angle sum is 180°, therfore we can add all the angles up to solve x
54 + 55 + x + 74 =180
183 + x =180
X = 180 - 183
X = - 3 °
Don't worry, negative result is normal and possible.
