Answer:
3) x=4 4)x = 9 5) x=5
Step-by-step explanation:
3) first you have to find the inside of the angle. A straight line = 180*
180-(19x+3) = 177-19x
Than you add all the angles up to equal 180.
(177 - 19x) + (11x-2) + (9x+1) = 180
if you simplify this x = 4. You can check your answer by subbing in for x.
4)first you have to find the inside of the angle. A straight line = 180*
180- (17x-23) = 203-17x
Than add the sides up to equal 180. keep in mind there are 2 of the same angles.
(203-17x)+(7x+2)(2) = 180
Simplify
x=9
5) 180-151=29* this is the inner angle.
(11x-1)+(20x-3)+29=180
31x+25=180
x=5
The fact that a connection is proportional if its graph is a line that runs through its origin should be stressed. This can be used to find the ratio in the proportional relationship.
<h3>How to explain the information?</h3>
When the graph of a connection is a line passing through the origin, the connection is proportionate. If it is not a line or ray that fails to do this, the ratio is not proportional. The equation for the proportionality constant is K = y/x. This is the same equation used to get the slope of a straight line with respect to the origin.
If the graph of a relationship is a line or ray that goes through the origin, the relationship is proportional. If the line or ray does not pass through the origin, it is not proportional.

Let's compute the two factors separately: as for "the sum of -13/5 and 12/7", we have to rewrite the two fractions so that they have the same denominator. Since the least common multiple of 5 and 7 is 35, we will change both fractions so that they have denominator 35:

So now we can sum them:

Multiplication is easier, since you just have to multiply numerators and denominators with each others:

Finally, we must divide the two fractions. Dividing by a fraction is the same this as multiplying by the inverse of that fraction, i.e. we have to switch numerator and denominator:

Without knowing what Juan's exact steps were, it's hard to say what he did wrong. The least you could say is that his solution is simply not correct.
4 sin²(<em>θ</em>) - 1 = 0
==> sin²(<em>θ</em>) = 1/4
==> sin(<em>θ</em>) = ±1/√2
==> <em>θ</em> = <em>π</em>/4, 3<em>π</em>/4, 5<em>π</em>/4, 7<em>π</em>/4
Answer:
D) I and II only
Step-by-step explanation:
C=
5/9(F−32)
If F goes up 1 degree (33 degrees)
C=
5/9(33−32)
C = 5/9 *1 = 5/9
So the first 1 is true
If C goes up 1 degree
1=
5/9(F−32)
Multiply each side by 9/5
9/5 = 9/5 * 5/9 (F-32)
9/5 = (F-32)
1.8 = F-32
Add 32 to each side
33.8 =F
The change from 33.8 to 32 is 1.8 degrees F so 2 is true
If F goes up 5/9 degree
C=
5/9(5/9)
C = 25/49
False
