Answer:

x=-3

Step-by-step explanation:

I did it with the parenthesis to make it easier so..

First, divide 16 and 4

All is left is x+7=4

Subtract 4 and 7

And the answer should be -3.... Hope this helped! If this is not the answer, I'm sorry but it's ok.

Micheal is three time as old as Jean in seven year he will be twice old as she will be then how old are they both
PtichkaEL [24]

Answer:

Michael is 21 years old while Jean is 7 years old.

Step-by-step explanation:

Given that Micheal is three times as old as Jean, but in seven years he will be twice old as she will be, to determine how old are they both at this time, the following calculation must be performed:

M = 3J

M + 7 = 2J + 7

7 = 1/3

7 x 3 = 21

21 + 7 = 28

7 + 7 = 14

21 / 7 = 3

28 / 14 = 2

 

Therefore, Michael is 21 years old while Jean is 7 years old.

One month, the price of gas was $1.44. The next month the price of gas was $2.40. What was the approximate percent of increase f
Lapatulllka [165]
Step 1:
Find the difference between the two numbers.
$2.40-$1.44= $0.96

Step 2:
Divide by the original number.
$0.96/1.44= 0.667

Step 3:
Multiply by 100 to find percent increase.
0.667 * 100= 66.7% rounded to one decimal place or 67% rounded

Hope this helped! :)

1 Without graphing, determine the characteristics of the graph.
olga nikolaevna [1]

Answer: (3, -1)

Step-by-step explanation:

y = |x-3|-1

When y=|x|, vertex is (0, 0).

Now, let's translate the graph so it becomes y = |x-3|-1.

|x| ==> |x-3|         Translate the graph 3 units to the right

Vertex: (0+3, 0) ==> (3, 0)

|x-3| ==> |x-3|-1     Translate the graph 1 unit down

Vertex: (3, 0-1) ==> (3, -1)

Vertex: (3, -1)

X+2y=10 6y=--3x+30 Use algebraic rules of equations to predict the solution to the system of equations.
MaRussiya [10]
X + 2y = 10 . . . (1)
6y = -3x + 30 . . . (2)

From (2), 3x + 6y = 30
3(x + 2y = 10)
3 x (1)

Since, the second equation is a multiple of the first equation, the system will have an infinitely number of solutions.
