As QS bisects <RQT into 2 congruent triangles
therefore, <RQS = <SQT
4x-25= 2x+5
2x= 30
x= 15
<RQS = 4x-25
= 4(15) -25
=60-25
= 35
Answer:
90
Step-by-step explanation:
Let x be Dany's score in geography. His score in chemistry is double his score in geography and it is equal to
2 x
The average of all four scores is 79. Hence
(93 + 88 + x + 2 x) / 4 = 79
Multiply both sides of the equation by 4
4×(93 + 88 + x + 2 x) / 4 = 4×79
Simplify
93 + 88 + x + 2 x = 316
Group like terms
3 x + 181 = 316
Solve for x
3 x = 135
3 x / 3 = 135 / 3
x = 45
score in geography = x = 45
score in chemistry = 2 x = 2 × 45 = 90
Hope it helped u if yes mark me BRAINLIEST!
Tysm!
What it is asking is 8 times what equals 48. The best way to do this is by doing the opposite operation. 48 divided by 8 equals 6. Then if you put it in the other way you get 8(6)=48 which works out. So the answer is 6.
Answer:
A
Step-by-step explanation:
In the inequality, you want to simplify it to get x on one side, and the numeric values on the other.
So, moving 9 to the other side, you get, 8x<-32
Then, you can divide by 8 on both sides to get x alone.
You get, x<-4.
From this, we can see that it should be an open dot at -4, and pointing to the left.
So, the correct number line is A.
