Step-by-step explanation:
1) the rule: m∠1+m∠2+m∠3=180°;
2) according to the rule above: m∠P+m∠Q+m∠R=180°;
x+x+43+2x-15=180°; ⇔ 4x=152°; ⇒ <u>x=38°</u>;
3) the angles: P=2x-15=<u>61°;</u> Q=x+43=<u>81°</u>; R=x=<u>38°</u>.
Answer:
Don't come at me if I'm wrong, but I think it's y=-3/4x-1 1/3
Step-by-step explanation:
1) you have to subtract 3x from both sides (this makes it 4y=-3x-4)
2) you then divide by 4 on both sides (it will become y=-3/4=4/3)
3) then you simplify the fractions (it becomes y=-3/4x-1 1/3)
The current quiz grade average of Malika using subtraction expression is 15/4.
- Subtraction is that the operation of taking the distinction of 2 numbers and . Here, is named the number and therefore the image between the and is named the sign. The expression " " is scan " minus ."
We have given the average points of Malika 4¹/₂ which on simplifying gives 4¹/₂ = 4 ×2 +1 / 2
= 8 +1 / 2
= 9/2
It is also given that at the end of the quarter, his average decreases by 3/4 point which can be represented by
Current quiz grade average = 9/2 - 3/4
= 18 - 3 / 4
= 15 /4
