Answer:

Calculate the percent value:

0.942 =

0.942 × 100/100 =

(0.942 × 100)/100 =

94.2/100 =

94.2%;

In other words:

1) Multiply that number by 100.

2) Add the percent sign % to it.

Answer:

The midpoint m of gh has coordinates ( -5, -4) point h has coordinates (-4, -7) find the coordinates of point g

Arte-miy333 [17]

Answer:

Step-by-step explanation:

The midpoint formula is

$M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$ and we have the coordinates of the midpoint and the coordinates of one endpoint. Filling that in we have:

$(-5,-4)=(\frac{-4+x_2}{2},\frac{-7+y_2}{2})$ and we will solve for the missing values one at a time. x first:

$-5=\frac{-4+x_2}{2}$ and

-10 = -4 + x₂ so

-6 = x₂ and do the same for y:

$-4=\frac{-7+y_2}{2}$ and

-8 = -7 + y₂ so

-1 = y₂

Thus, the coordinates of point g are (-6, -1)

A dozen of doughnuts cost $5 and a dozen of croissants cost $6.

Step-by-step explanation:

Let,

Cost of 1 dozen doughnuts = x

Cost of 1 dozen croissants = y

According to given statement;

7x+3y = 53 Eqn 1

x+5y = 35 Eqn 2

Multiplying Eqn 2 by 7

$77(x+5y = 35)\\x+35y=245\ \ \ Eqn\ 3$

Subtracting Eqn 1 from Eqn 3

$(7x+35y)-(7x+3y)=245-53\\7x+35y-7x-3y=192\\32y=192$

Dividing both sides by 32

$\frac{32y}{32}=\frac{192}{32}\\y=6\\$

Putting y=6 in Eqn 2

$x+5(6)=35\\x+30=35\\x=35-30\\x=5$

A dozen of doughnuts cost $5 and a dozen of croissants cost $6.
