Answer:

X=-2

Step-by-step explanation:

1. Open up the brackets

You then get

6+8x+12=2

2. Send the whole numbers to the other sides

8x= 2-6-12

8x = - 16

3. Divide both sides by 8 to leave x alone

X=-2

Rolando is 17. In four years, his age will be 3/2 the age of his sister Marisa. How old will Marisa be in three years
Bess [88]
To find the answer, we can first find the age of Rolando in four year:

17+4
=21

We can then proceed to find the current age of Marisa,which is 3/2 of Rolando’s age calculated above:

Let Marisa’s age be y.

3/2 y =21
y = 21 × 2/3
y = 42/3
y = 14

Therefore Marisa is currently 14 years old.

In three years, Marisa would be:

14+3
=17

Therefore, she will be 17 years old.

Hope it helps!

Please help anyone and explain please

So if you distribute 4 in the first parentheses, you get 12x+20y+8z.

Then you distribute 3 in the second parentheses. You'll get 3x-3z. That all equals 12x+20y+8z+3x-3z.

Now you have to start combining numbers with the same variable. Start with x. 12x+3x is 15x.

y has no other common variable, it's left alone.

8z-3z is 5z

All together now with the numbers in simpler form, the equation is 15x+20y+5z

Jenna's would be the right answer because when you distribute 5 in her answer you get 15x+20y+5z

Factorise 5x + 40 <br> 7x - 49<br> 18x + 9<br> 15x - 10
Vera_Pavlovna [14]

<em><u>Factorization is:</u></em>

5x+40=5(x+8)\\\\7x-49=7(x-7)\\\\18x+9=9(2x+1)\\\\15x-10=5(3x-2)

<h3><u>Solution:</u></h3>

Given that we have to factor the given expressions

<h3><u>First expression:</u></h3>

5x + 40

We have to take the greatest common factor out

When we find all the factors of two or more numbers, and some factors are the same then the largest of those common factors is the Greatest Common Factor

Take G.C.F of 5 and 40

The factors of 5 are: 1, 5

The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40

Then the greatest common factor is 5

Factor out 5 from given expression

5x + 40 = 5(x+8)

<h3><u>Second expression:</u></h3>

7x - 49

Similarly, take G.C.F of 7 and 49

The factors of 7 are: 1, 7

The factors of 49 are: 1, 7, 49

Then the greatest common factor is 7

Factor out 7 from given expression

7x - 49 = 7(x-7)

<h3><u>Third expression:</u></h3>

18x + 9

Similarly, take G.C.F of 18 and 9

The factors of 9 are: 1, 3, 9

The factors of 18 are: 1, 2, 3, 6, 9, 18

Then the greatest common factor is 9

Factor out 9 from given expression

18x + 9 = 9(2x+1)

<h3><u>Fourth expression:</u></h3>

15x - 10

Similarly, take G.C.F of 15 and 10

The factors of 10 are: 1, 2, 5, 10

The factors of 15 are: 1, 3, 5, 15

Then the greatest common factor is 5

Factor out 5 from given expression

15x-10 = 5(3x-2)

Thus factorization is found

(a) y = 5z + x simplify x​
jolli1 [7]

Answer:

x=y−5z

Step-by-step explanation:

y=5z+x

Step 1: Flip the equation.

x+5z=y

Step 2: Add -5z to both sides.

x+5z+−5z=y+−5z

x=y−5z

Answer:

x=y−5z
