Answer:
a = -40/3
Step-by-step explanation:
(7a - 4) = (4a - 44)
7a - 4 = 4a - 44
7a = 4a - 44 + 4
7a = 4a - 40
7a - 4a = - 40
3a = - 40
3a/3 = -40/3
a = -40/3 or -13.3333 repeating
To the nearest percentage point, what percentage of students who play a sport don’t play a musical instrument?
First, using the information given, fill out the chart with the rest of the data (in the image attached)
Then find the number of students who play a sport and don’t play a musical instrument, which in the chart is 11
Place 11 over the total:
and convert to a percentage:
44%
Solution:
we are given that ΔABC and ΔXYZ are similar triangles.
As we know , when two triangles are similar then the ratios of their corrsponding sides are equal.
Here we have
BA = x + 9, AC = x + 7, YX = x + 5, and XZ = x + 4
So we can write

Hence then value of x=-1.
B divided by ten means to divide whatever b equals by ten, b divided int ten means dividing whatever b equal into ten groups. THEY MEAN THE SAME THING!!
5/3 means (5 over 3 since I can't do fractions on this)
5/3-3/3=___
5-3=2 first you do the numerators
You keep the denominator the same since both denominators are 3
Then you put it together and get 2/3 and since 2/3 can't be reduced, 2/3 is the answer
