Let's say 'x' represents your first dog and 'y' represents your 2nd dog.

You know that x = 5 ft long. You also know that x = 4/5y. So let's plug in 5 for 'x' in the 2nd equation and solve for 'y'.

5 = 4/5y

Divide 4/5 to both sides or multiply by its reciprocal, 5/4.

6.25 = y

So your 2nd dog is 6 1/4 ft long.

You would typically use ounces to measure the amount of juice in a glass. The other measurements are too large.

Solve for b. -11b+7 = 40−11b+7=40

Oksana_A [137]

Answer:

This equation is false

Step-by-step explanation:

Well,

-11b + 7 = 4 - 11b + 7 = 40

combine like terms

-11b + 7 = -11b + 3 = 40

Communicative property

-3 to both sides

-11b + 4 = -11b = 40

-4 to both sides

-11b = -11b = 36

+11b to both sides

0 = 36

0 is not equal to 36 meaning that this equation is false.

Thus,

the equation given is false.

Hope this helps :)

Solve the equation 1) 4.3^x+1 = 27+9^x 2) 3^x+5= 3^x+3+8/3

Bad White [126]

Answer:

Step-by-step explanation:

4*3^x+1=27+(3^2)^x

(3^2)^x=(3^x)^2

3^x=t

4t+1=27+t^2

t^2-4t+27-1=0

t^2-4t+26=0

delta=4^2-4*1*26=16-84=-68<0

the equation has not real solutions

BRAINLIEST AND 60 POINTS!!!!!!!

PIT_PIT [208]

Answer:

1. P ( tails) = 1/2

2.P (number greater than 4) = 1/3

3. P (2 die sum to 8) = 5/36

Step-by-step explanation:

A coin only has 2 possibilities, head or tails, and they are equally likely

So the probability of getting a tails is 1/2

P ( tails) = 1/2

A die has the numbers 1,2,3,4,5,6 . There are 2 numbers greater than 4. They are 5 and 6. So there are 2 of the 6 choices that work.

P (number greater than 4) = 2/6 = 1/3

See the dice chart

There are 36 possibilities when you roll the die.

There are 5 that sum to 8

P (2 die sum to 8) = 5/36
