Angle 1 = 130°
Angle 2 = 124°
Angle 3 = 56°
Angle 4 = 52°
Angle 5 = 72°
Angle 6 = 94°
I primarily used the triangles to get my answers. Remember the angles in a triangle add up to 180°.
B- 1/2 the books are science books. You have to add the two fractions and subtract that from one.
Answer:
or ![-\frac{7}{10}](https://tex.z-dn.net/?f=-%5Cfrac%7B7%7D%7B10%7D)
Step-by-step explanation:
![-0.75-(-\frac{2}{5})+0.4+(-\frac{3}{4})](https://tex.z-dn.net/?f=-0.75-%28-%5Cfrac%7B2%7D%7B5%7D%29%2B0.4%2B%28-%5Cfrac%7B3%7D%7B4%7D%29)
The opposite of
is ![\frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D)
![-0.75 + \frac{2}{5} +0.4 - \frac{3}{4}](https://tex.z-dn.net/?f=-0.75%20%2B%20%5Cfrac%7B2%7D%7B5%7D%20%2B0.4%20-%20%5Cfrac%7B3%7D%7B4%7D)
Convert decimal number −0.75 to fraction
.
Reduce the fraction
to lowest terms by extracting and canceling out 25.
![-\frac{3}{4} + \frac{2}{5}+0.4-\frac{3}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B4%7D%20%2B%20%5Cfrac%7B2%7D%7B5%7D%2B0.4-%5Cfrac%7B3%7D%7B4%7D)
Least common multiple of 4 and 5 is 20. Convert
and
to fractions with denominator 20.
![-\frac{15}{20}+ \frac{8}{20} +0.4 - \frac{3}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B15%7D%7B20%7D%2B%20%5Cfrac%7B8%7D%7B20%7D%20%2B0.4%20-%20%5Cfrac%7B3%7D%7B4%7D)
Since
and
have the same denominator, add them by adding their numerators.
![\frac{-15 +8}{20} +0.4-\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B-15%20%2B8%7D%7B20%7D%20%2B0.4-%5Cfrac%7B3%7D%7B4%7D)
Add -15 and 8 to get -7
![-\frac{7}{20}+0.4-\frac{3}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B7%7D%7B20%7D%2B0.4-%5Cfrac%7B3%7D%7B4%7D)
Convert decimal number 0.4 to fraction
. Reduce the fraction
to lowest terms by extracting and canceling out 2.
![-\frac{7}{20}+\frac{2}{5}-\frac{3}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B7%7D%7B20%7D%2B%5Cfrac%7B2%7D%7B5%7D-%5Cfrac%7B3%7D%7B4%7D)
Least common multiple of 20 and 5 is 20. Convert
and
to fractions with denominator 20.
![-\frac{7}{20}+\frac{8}{20}-\frac{3}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B7%7D%7B20%7D%2B%5Cfrac%7B8%7D%7B20%7D-%5Cfrac%7B3%7D%7B4%7D)
Since
and
have the same denominator, add them by adding their numerators.
![20-7+8-\frac{3}{4}](https://tex.z-dn.net/?f=20-7%2B8-%5Cfrac%7B3%7D%7B4%7D)
Add -7 and 8 to get 1.
![\frac{1}{20}-\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B20%7D-%5Cfrac%7B3%7D%7B4%7D)
Least common multiple of 20 and 4 is 20. Convert
and
to fractions with denominator 20.
![\frac{1}{20}-\frac{15}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B20%7D-%5Cfrac%7B15%7D%7B20%7D)
Since
and
have the same denominator, subtract them by subtracting their numerators.
![\frac{1}{20}-15](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B20%7D-15)
Subtract 15 from 1 to get -14.
![20-14](https://tex.z-dn.net/?f=20-14)
Reduce the fraction
to lowest terms by extracting and canceling out 2.
or ![-0.7](https://tex.z-dn.net/?f=-0.7)
Hope this helps! Brainliest would be much appreciated! Have a great day! :)
Answer:
No, David's answer does not seem reasonable.
Let x= original purchase amount
25x = $10.25, so solve for x by dividing both sides by .25, and you get x = $41.
If the shirt was $18, the shorts must have been $41-$18 = $23 NOT $41.

Answer:
16 because if each chair has 4 legs you multiply that by the amount of chairs you have. 4x4=16
Step-by-step explanation:
4x4=16
