Answer:

see the explanation and the attached figure

Step-by-step explanation:

we have

$-2(x+1)=8$ ----> given

Divide by -2 both sides

$-2\frac{(x+1)}{-2} =\frac{8}{-2}$ ----> by Division Property of Equality

Simplifying

$x+1=-4$

Subtract 1 both sides

$x+1-1=-4-1$ ----> by Subtraction Property of Equality

Simplifying

$x=-5$

Find two numbers such that the sum of the first and three times the second is 5 and the sum of the second and two times the firs

Sav [38]

Answer:

first number= 19/5

second number= 2/5

Step-by-step explanation:

first number= a

second number= b

a+3b=5 equation 1

b+2a=8 equation 2

using equation 2 we have

b=8-2a

using equation 1 we have

a+3(8-2a)=5

a+24-6a=5

24-5=6a-a

19=5a

a=19/5 = first number

so using b=8-2a

we have

b=8-2(19/5)

b=8-(38/5)

b=2/5 = second number

The height of Atlas V rocket used for space lifts was 205 feet. What is the height of a model of Atlas V rocket if the scale fac

KengaRu [80]

Answer: 6.4 feet

Step-by-step explanation:

Height of Atlas V rocket = 205 feet

Ratio of the model = 1:32 = 1/32

Model / Real = 1/32

Since Real height = 205, we put it into the equation and this will be:

Model / Real = 1/32

Model / 205 = 1/32

Model × 32 = 205 × 1

Model = 205/32

Model = 6.4 feet

The height of the model is 6.4 feet.
