To find X, set up a ratio with the given dimensions:
10/15 = X/42
Cross multiply:
420 = 15x
Divide both sides by 15:
x = 420 / 15
x = 28
can u show me a shorter verison
Answer:
Go 6 units to the right and then 8 units up.
Answer:
10/11
Step-by-step explanation:
At first we have to swap the fractions to make those fractions into a normal number. Because it will become a multiplication.
4 × (x + 5) < 5 × (3x + 2)
We will multiply the numbers by the brackets.
4x + 20 < 15x + 10
Now we swap the constant and values from left to right side.
4x - 15x < 10 - 20
or, - 11x < -10
If we divide the inequality by a negative number, say - 11, the inequality becomes reverse.
Therefore,
[-11x ÷ (-11)] > [(-10) ÷ (-11)]
or, x > (10/11)
Here the order of operation is very important. I put few parenthesis to show you what is the correct result. First you have to multiply/divide, then u can add/subtract
