Answer:
43% of the trip
Step-by-step explanation:
1. Create an Equation
300 miles/100*x percent=129 miles <=== Make an equation so you can find the percent she slept of the trip
2. Solve
300 miles/100*x percent=129 miles
3x=129 <=== 300 divided by 100 is 3 and 3 times x is also 3x
3x/3=129/3 <=== divide by 3 from both sides
x=43
Since x is 43 that means 129 equals 43% which is how much Tallulah slept
of the trip.
3. Check
300 miles/100*43%=129 miles <=== Substitute x with 43%
3x43%=129
129=129 <=== 129 is 129 which means that the answer is correct!

Answer:
84 degrees
Step-by-step explanation:
Angle A = 83 degrees
Angle B = x degrees
Angle C = 135 degrees
Angle CDE = 122 degrees
We know that the four inner corners of a quadrilateral should add up to 360 degrees. Two supplementary angles will add up to 180 degrees. Adjacent angles on a straight line will always be supplementary. Knowing this, just solve for <ADC and add that amount to <A and <C. Then, subtract that sum from 360 degrees.
<ADC = 180-122 = 58
58+83+135 = 276
360-276 = 84 degrees
Y=x^2-5 due to the fact that it has four parts even though it only looks as if it has three here. Just look for a square root and that is the one
2 of the necklaces are blue.
Because she has 8 necklaces in total and 1/4 of those 8 are blue, you would divide 8 by 4.
1/4 of 8 is equal to 2
