Answer:
v = 7i + 2j
w= - 4i + j
10v = 10(7i + 2j) = 70i + 20j
3w= 3(- 4i + j) = -12i + 3j
10v + 3w
= 70i -12i + 20j +3j
= 58i + 23j
Hope this helps.

division problem. But I will showing the easiest one.
15.75 divided by 0.25
=> In every 1 whole number, there are 4 of 0.25
Now we have 15 as whole number so simply multiply 15 x 4
=> 15 * 4 = 60, there are 60 pieces of .025s in 15.
=> 0.75 has 3 0.25s
Now, let’s add 60 + 3 = 63, the answer is 63.
There are 63 pieces of 0.25 in 15.75.
Let’s check
=> 15.75 / 0.25
=> 63</span>
Answer:
x=13
y= -9
(13, -9)
Step-by-step explanation:
If we are solving using the substitution method, we can take the first equation and set it to y so y=4-x.
Then, we can take that equation and plug it into the bottom one so
3x+4(4-x)=3
Simplify:
3x+16-4x=3
-x=-13
x=13
We can then plug 13 into any of the two given equations (I am just going to plug it into the top one)
So, 13+y=4 which y= -9
