Answer:
300
Step-by-step explanation:
because when multiply then divide all of them then find a percent 300 is your answer
Answer:
use -9 to multiply the first equation
use -4 to multiply the second equation.
Step-by-step explanation:
5x-4y=28.....eqn (1)×-9
3x-9y=30....eqn(2)×-4
-45x+36y=-252
-(-12x+36y=-120)
therefore, -33x÷33 =-132÷-33
x=4.
substitute (x=4) in any of the equation. I'm just going to use eqn 1.
5x-4y=28
5(4)-4y=28
20-4y=28
-4y =28-20
-4y÷-4 = 8÷-4
y=-2
so, x=4, y=-2
Note: for proof of answers substitute the answers for x and y and see if you have the same result...e.g
5(4)-4(-2)=28.
Option A:
6 – 4(3) < 5 – 10
Solution:
Given expression is 6 – 4(3) ____ 5 – 10.
Let us first simplify the expression.
Take left side expression.
⇒ 6 – 4(3)
⇒ 6 – 12
⇒ –6
Take right side expression.
⇒ 5 – 10
⇒ –5
To find which symbol makes the expression true.
In negative the highest number is the lowest in value.
–6 < –5
⇒ 6 – 4(3) < 5 – 10
Option A is the correct answer.
Hence 6 – 4(3) < 5 – 10.
