Answer:
378 marbles are blue, and 270 marbles are red
Step-by-step explanation:
The total number of ratio units must be multiplied by 6 to get the total number of marbles. Hence the number of blue marbles is 63×6 = 378, and the number of red marbles is 45×6 = 270.
Answer:
=−2x−5y
Step-by-step explanation:
Let's simplify step-by-step.
6x−5y−12x+4x
=6x+−5y+−12x+4x
Combine Like Terms:
=6x+−5y+−12x+4x
=(6x+−12x+4x)+(−5y)
=−2x+−5y
It would be 4d because there is a one in from the d that is by itself but you cannot see it and therefore 5d-1d= 4d.
Hope this helps! :)
Answer:
As a fraction it's ¼, as a decimal it's 0.25 and as a percentage it's 25%
Answer:
A) x = 12
B) = 154
Step-by-step explanation:
RVT is a straight line so it must have an angle of 180º. If we take the 26º from ST we know that RS is equal to 154º
So we should set the equation (15x-26) = 154
We should always keep the equation balanced so to do this we're going to add 26 to both sides to get x by itself.
Your equation should now look like this. 15x = 180
Then divide both sides by 15 to get x = 12
We know that UR is also 26º because RS is 154º That makes RU congruent to ST and RS congruent to UT
