Corresponding altitudes are corresponding parts. They are congruent because ... Corresponding parts of congruent triangles are congruent. (CPCTC)
Answer:
Y= 5
Step-by-step explanation:
14+13Y=20Y-21
-13y -13y
14=7y-21
+21 +21
35/7=7y/7
y=5
Answer:
D.
Step-by-step explanation:
1. Answer A:
15 students signed up for violin lessons (4 boys + 11 girls)
15 / 70 = approx. 21% of the class.
Answer A says 28%, so this is incorrect.
2. Answer B:
17 students signed up for drum lessons (11 boys + 6 girls)
17/70 = approx. 24%
B says 17% signed up for drums, so this is incorrect.
3. Answer C.
Wrong because more girls signed up for piano lessons (15 girls, whereas only 9 boys signed up for piano)
4. D. The same percent of boys and girls are taking guitar lessons.
Get the total number of boys and girls in the class (just add the results for each separately for all instruments)
Boys: 11 + 6 + 9 + 4 = 30
Girls: 6+8+15+11 = 40
6 out of 30 boys signed up for guitar
6/30= 20%
8 out of 40 girls signed up for guitar
8/40 = 20%
Answer is D
Answer:
The difference of z and y must be 2x
Step-by-step explanation:
Y=5x-2
i’m assuming gradient means slope and you put the slope number next to x and the y-intercept at the end
