Answer:
m∠2=47.5°
m∠3=42.5°
m∠4=42.5°
Step-by-step explanation:
We are given in the question that m∠1=47.5 degrees=47.5°.
<em>" Angles are</em><em> congruent </em><em>if they have the same angle measure in degrees" ----(1)</em>
As we are given that ∠1 is congruent to ∠2.
This implies from statement (1) that:
m∠2=47.5 degrees=47.5°
<em>" Complementary Angle: Two Angles are </em><em>Complementary</em><em> when they add up to 90 degrees (a Right Angle)."</em>
In the question we are given ∠1 and ∠3 are complementary.
This means ∠1+∠3=90°
⇒ ∠3=90°-∠1
⇒ ∠3=90°-47.5°=42.5°
Hence, m∠3=42.5°
Also we are given that ∠2 and ∠4 are complementary.
This means ∠2+∠4=90°
⇒ ∠4=90°-∠2
⇒ ∠4=90°-47.5°=42.5°
Hence, m∠4=42.5°.
8=4x-6x
8= -2x
8/-2= -2x/-2
X=-4
First step:Combine like terms so subtract 4x-6x= -2x so you will get 8=-2x
Note: You combine it because there both x and there in the same equal sign position.
Second step: Get x by it self by dividing -2 on each side as shown above.You divide it because you do the opposite of multiplying.
Answer x=-4
Sorry Idk where the equal sign is I am skipping the second problem.
-21-2b= -3(2b-1)
-21-2b= -6b+3
+2b +2b
-21= -4b+3
-3 -3
-24= -4b
-24/-4= -4b/-4
6=b or b=6
I hope I helped sorry I didn't explain this problem step by step like the 1 st one.
Answer:
the first one is graph c and the second, graph b.
Step-by-step explanation:
They are both linear inequalities, so for both, you have to solve for x first. For the first one, since x is basically multiplied to 2 (2x), you have to divide both sides to get x by itself, and you get x>25. The graph has to have an opened circle, and the arrow should go to the right because all the numbers greater than 25 can be x. For the second one, you have to subtract 6 to both sides to get x by itself which then leaves you with ×<26. This one should also be an opened circle, and is going to the left, because all the numbers less than 26 can be x.

95% is the same as 0.95
