Answer:(12,17)
Step-by-step explanation:
X + y= 29
4.50x + 7y=173
Solve by elimination.
First, subtract 2x from both sides of the equation to get 8y = -2x - 32. Then, divide the equation by 8, to get y = -x/4 - 4. Your y-intercept will be -4, and it's slope will be -1/4.
Answer: 6y I think. If you would have to add all of the y’s and so you would have 3 y’s and then you add both 3 y’s so 6y
I don’t know if I am right sorry if I’m wrong
Answer:
SAS
Step-by-step explanation:
Given: Two triangles ΔABD and ΔDCA,
We have, AD=AD (common)
∠A=∠A (Given)
BA=CD (Sides opposite to equal angles are always equal)
With the SAS rule of congruency,
ΔABD≅ΔDCA
Answer:
30 students
Step-by-step explanation:
Yesterday: 1/3 of the 75 students (75 / 3) = 25 students
There are now 50 students remaining to give their speeches.
Today: 2/5 of the 50 students (50 / 5 = 10 x 2 ) = 20 students
50 - 20 = 30 students remaining to give their speeches.
