Answer:
-0.55-0.05
Step-by-step explanation:
When you solve (0.25-0.3)-(0.8-0.25), you get -0.6. -0.55-0.05= -0.6
Answer:
x=4
y=3
Step-by-step explanation:
we have the following equations
3x+y=15 equation 1
5x-4y=8 equation 2
using equation 1 we have:
y=15-3x equation 3
using equation 3 in equation 2 we have:
5x-4(15-3x)=8
5x-4*15+4*3x =8
5x-60+12x = 8
17x=68
x=68/17
so we have x=4
finally in equation 3:
y = 15-3(4)
y = 15-12
y = 3
Answer:
8820 ways
Step-by-step explanation:
Given that :
Selecting 4 pairs of pant from 8 available and selecting 5 shirts from 9 available
Using combination :
4 pants from 8 = 8C4
5 shirts from 9 = 9C5
Recall:
nCr = n! / (n-r)! r!
8C4 * 9C5 = [8! /(8-4)!4!] * [9! /(9-5)!5!]
8C4 * 9C5 = (8! /4!4!) * (9! /4!5!)
8C4 * 9C5 = 70 * 126
8C4 * 9C5 = 8820 ways
Answer:
C
Step-by-step explanation:
Since the triangles are congruent then corresponding angles are congruent
x is the angle between line with 3 strokes and 2 strokes
The corresponding angle is therefore ∠ C
∠ C = 180° - (63 + 29)° = 180° - 92° = 88°
Then x = 88 → C
The value that would make the ratios equal to 4 to 10... I believe it would be 2 to 5
