x = 3x - 70 as corresponding angles

2x = 70

x = 35

∠LMN = 3x - 70 = 3*35 - 70 =35⁰

∠LMN = 35⁰

[True]

Natural numbers are the positive integers (whole numbers) such as 1, 2, 3, and etc. So it is true that zero is less than every natural number.

The 8 in 30,846 is in the hundreds place because the 8 stands for 800.

The mean length of 6 childrens' big finger is 12.6cm.

malfutka [58]

14.94 cm ( to 2 dec. places )

We require the sum totals of the 2 groups before calculating the mean of all 14

using mean = $\frac{sum}{count}$

Children's sum

12.6 = $\frac{sum}{6}$ ( cross-multiply )

sum = 6 × 12.6 = 75.6

Adult's sum

16.7 = $\frac{sum}{8}$ ( cross- multiply )

sum = 8 × 16.7 = 133.6

Total sum of all 14 = 75.6 + 133.6 = 209.2

mean = $\frac{209.2}{14}$ = 14.94 cm

Ollie earns a fixed amount of $2,700 per month and a commission of 12% on all of his sales for the month. To cover all of his ex

storchak [24]

Answer:

Part A) $0.12x+2,700\geq 5,400$

Part B) see the explanation

Step-by-step explanation:

Part A) Write an inequality that will represent the amount of sales Ollie will need in order to cover his monthly expenses

Let

x ----> the amount of sales monthly

Remember that

$12\%=12/100=0.12$

we know that

The fixed amount of $2,700 plus the commission of 12% on all of his sales for the month must be greater than or equal to $5,400

The inequality that represent this problem is

$0.12x+2,700\geq 5,400$

Part B) Find the solution and describe what the graph would look like on a number line

we have

$0.12x+2,700\geq 5,400$

Solve for x

subtract 2,700 both sides

$0.12x \geq 5,400-2,700\\0.12x \geq 2,700$

Divide by 0.12 both sides

$x\geq \$22,500$

The minimum amount of sales needed to cover his monthly expenses is $22,500

In a number line the solution is the shaded area at right of x=22,500 (closed circle)

see the attached figure to better understand the problem

Find the point slope equation for the line that passes through the points (1,-9) and (-10,101)

neonofarm [45]

Answer:

( y + 9 ) = -10( x - 1 )

Step-by-step explanation:

First we calculate the slope

$m=\frac{-9-101}{1-(-10)} =-10$

Then we choose a point it could be (1,-9) or (-10,101), I choose (1,-9), the slope point form is (y-y1)=m(x-x1)

( y - (-9) ) = -10( x - 1 )

( y + 9 ) = -10( x - 1 )

it could be also...

( y - 101 )= -10( x- (-10) )

( y - 101 ) = -10( x + 10 )
