Answer:

x=-9

Step-by-step explanation:

-3×-4= 12x -3×15=-45

4x+12x-45=-189

4x+12x=16x

16x-45=-189

16x=-144

x=-9

-4x + 7 = 11 help me please!

lyudmila [28]

-4x + 7 = 11

First, subtract 7 from both sides. / Your problem should look like: $-4x = 11 - 7$
Second, subtract 11 - 7. / Your problem should look like: $-4x = 4$
Third, divide both sides by -4. / Your problem should look like: $x = \frac{4}{-4}$
Fourth, change the fraction to a negative. / Your problem should look like: $x = -\frac{4}{4}$
Fifth, cancel 4 out. / Your problem should look like: $x = -1$

Answer: x = -1

For 6 consecutive days, Alejandro studied for 5 minutes more each day than he did the previous day. Which best represents the ch

Andreyy89

Let's say the first day he studied for x minutes.
Each day he studies 5 more minutes than his previous day.
Day 2: x +5
Day 3: x + 10
Day 4: x + 15
Day 5: x + 20
And finally the last day: x + 25

To find the difference all u need to do is take the amount he studied on the first day and subtract it by how much he studied the last day.

X - X + 25
Which gives u a difference of 25
