Answer:
-1.5-32-16ij
Step-by-step explanation:
When you substitute it you will get (3i+8j)(-0.5i-4j)
Then you will use FOIL
From this, you get -1.5-32-16ij

Answer:
11 ½
Step-by-step explanati10min stretching + total jogging minutes = 43 minutes
total jogging minutes= 23 minutes
3 minutes is 1 lap,
23 minutes is ?
=23/2
=11 and a half lap(s)
3(x+2)-6x+6<0 "< is like equal sign bruv"
3x+6-6x+6<0 "do group so ( ) so multiply and bring everything else down"
-3x+12<0 "add all like terms so "3x-6x" and "6+6" since they cancel out you get "
-3x< 0-12 "to get rid of 12 you subtract 12 and subtract it from the other side so 0 aswell
-3x<-12 "you would end up with this"
-3x/-3 < -12/-3 "since dividing or multiplying by a negative you flip the arrow"
x > 4 "this is the answer"
Answer:
2<em>x </em>+ 7 = 25
<em>x </em>= 7
Step-by-step explanation:
Gary: 25
Sean: <em>x</em>
----------------------------
Let's break down the sentence into mathematical terms
Gary <u>is</u> 25 years old. That <u>is</u> 7 more than twice <u>Sean's age.</u>
In math, is means equal to. It is represented with an equal sign (=)
Gary = 25. 25 = 7 more than twice <u>Sean's age.</u>
7 more is represented by 7 +
Gary = 25. 25 = 7 + than twice <u>Sean's age.</u>
Twice means double which is 2 ·
Gary = 25. 25 = 7 + 2 · <u>Sean's Age</u>
<u>Sean's Age</u> will be represented by <em>x</em>
Gary = 25. 25 = 7 + 2<em>x</em>
We don't need it to say<em> "Gary = 25" </em>in our equation.
25 = 7 + 2<em>x</em>
Let's rewrite it with the associative property.
2<em>x </em>+ 7 = 25
---------------------
Now, solve
2<em>x </em>+ 7 = 25
<em>-7 -7</em>
2<em>x</em> = 18
<em>÷</em><em>2 </em><em>÷</em><em>2</em>
<em>x </em>= 7
----------------------
Sean is 7 years old.
