It’s just simple multiplication
Answer:
The answer would be (-2, -5)
Step-by-step explanation:
3x - 8y= 34
2(7x + 4y = -34)
3x - 8y=34
14x + 8y= -68
----------------------
17x= -34 divided by 17
x = -2
3(-2) -8y= 34
-6 -8y =34 add 6
-8y= 40 divide by -8
y = -5
if you want to check the answer replacing -2 for x and -5 for y
7(-2) + 4(-5)= -34
-14 + (-20) = -34
-34 = -34
I hope this help sorry I'm not good explaining
Answer:
£175
Step-by-step explanation:
Given the exchange rate was £1 = 1.84 dollars.
We are to change 322 dollars to pounds (£).
£1 = 1.84 dollars.
x = 322 dollars
Cross multiply
1.84 * x = 322
1.84x = 322
x = 322/1.84
x = 175
Hence 322 dollars in pounds will be £175
The first thing we are going to do is rewrite the expression correctly.
We have:
root (27x ^ 12 / 300x ^ 8)
Rewriting:
root ((27/300) * (x ^ 12 / x ^ 8))
root ((9/100) * (x ^ (12-8)))
root ((9/100) * (x ^ (4)))
root ((9/100) * (x ^ (4)))
3 * x ^ 2 * root ((1/100)
(3 * x ^ 2) / 10
(3/10) * (x ^ 2)
Answer:
(3/10) * (x ^ 2)
