Answer:
1) 4
2) 45
3) 104
Step-by-step explanation:
1)
let x be your number.
((6x+8)/4)-5 = 3
add 5
(6x+8)/4=8
multiply by 4 to get rid of the denominator
6x+8=32
subtract 8
6x=24
divide by 6
x=4
2) Same type. (this time I won't explain every step)
let x be your number
((x/9)-8+6)*7 =21
(x/9)-8+6=3
(x/9)-2=3
x/9 = 5
x=45
3) Same type... Again
let x be your number
(((x-4+11)*2)/6)-8 = 29
((x-4+11)*2)/6=37
(x-4+11)*2 = 222
x+7=111
x= 104
Start by taking the total number of golf balls, 360, and dividing it by how many golf balls come in each pack, to find the number of packs.
360 ÷ 24 = 15
So there are 15 packs, each with 3 yellow golf balls.
15 · 3 = 45
Meaning 45 of the golf balls would be yellow
Answer:
4
Step-by-step explanation:
For WX to be perpendicular to YZ, then the product of their slope must be -1
For slope of WX
W(2-3) and X(-4.9),
Mwx = 9-(-3)/-4-2
Mwx = 12/-6
Mwx = -2
For slope of Y(5. y), and Z(-1, 1),
Myz = 1-y/-1-5
Myz = 1-y/-6
Since Mwx•Myz = -1
-2•(1-y/-6) = -1
1-y/3 = -1
1-y = -3
-y = -3-1
-y = -4
y = 4
Hence the value of y is 4
Answer:
2m/5-1/5
Step-by-step explanation:
2*m-2/5+3/5
2(m-2)/5+3/5
2(m-2)/5+3/5
2m-4/5+3/5
2m/5-1/5
Answer:
53 degrees
Step-by-step explanation:
1) Base angle- 63.5 degrees: Given
2) Other base angle is- 63.5 degrees: Base Angle Theorem
3) Sum of angles in triangle: 2(63.5)= 127
180-127= 53
53 degrees
