3 tens is 3 * 10 = 30
9 ones is 9 * 1 = 9
30 + 9 = 39
Answer: 39
Answer:
male comedy: 31 male drama: 9
female comedy: 36 female drama: 24
Step-by-step explanation:
add f+m=100 total
31 males for comedy
40 males - 31 males = 9 males for drama
55% chose comedy so 55-31 males = 24 females for comedy
60 total females - 24 for comedy = 36 females for drama
Answer:
B
Step-by-step explanation:
For each equation, set x to 0. A is correct because if x=o, then y will equal 38.910.
Answer:
Step-by-step explanation:
let a=Ann's amt., b=Betty's amt.
a=2b+9
b+2b+9=60
3b+9-9=60-9
3b=51
b=$17
a=34+9=$43
Answer:
y = 2x + 4
Step-by-step explanation:
Two points on this line are (-2, 0) and (0, 4). Going from the first to the second, x increases by 2 (this is the 'run') and y increases by 4 ('rise').
Thus, the slope of this line is m = rise / run = 4/2 = 2
Using the slope-intercept formula, we get y = mx + b = 2x + b
Let x = -2 and y = 0 to find b: 0 = 2(-2) + b, so b = 4, and the desired equation is then:
y = 2x + 4
