Answer:
15
Step-by-step explanation:
12 X 15 is 180, which is closest to 187, we have to add a 5 in the space next to 71 and 180 under 187
Answer:
I. C
II. A, D
III. B
Lines that coincide have infinite solutions, and parallel lines have no solutions.
Step-by-step explanation:
3. To solve this equation, look at the slopes of the equation. The equations are in y=mx+b form. m is equal to the slope.
Equations with different slopes will have one solution, meaning that the lines will intersect once.
Equations with the same slope will either have no solutions or infinite solutions. <u>If the equations are the exact same</u>, it will have infinite solutions, meaning that the line "intersects" itself in infinite places since its basically one line right on top of another. <u>If the equations have different y-intercepts</u>, it will have no solutions because the lines are going at the same angle, are parallel and will never intersect.
This means that A and D have one solution, B has infinite solutions, and C has no solutions.
4. Lines that coincide have infinite solutions, and parallel lines have no solutions.
Answer:
THEY ARE 37 AND 28
Step-by-step explanation:
LET THE NUMBERS BE X AND Y
X = 9 + Y
X - Y = 9 ........1
X + Y = 65 .....2
ADDING 1 AND 2
2X = 74
DIVIDING BY 2
2X/2 = 74/2
X = 37
AND X = 9 + Y
: Y = X - 9
PUTTING X = 37
Y = 37 - 9
Y = 28
