Answer:
42
Step-by-step explanation:
42 is divisible by both 7 and 2
The number which has prime factors of 2 and 7 and in between 40 and 45 is 42.
Given that, a number is between 40 and 45. It has prime factors of 2 and 7.
What are prime factors?The process of writing a number as the product of prime numbers is prime factorization. Prime numbers are the numbers that have only two factors, 1 and the number itself.
The numbers between 40 and 45 are 41, 42, 43 and 44.

Consider circle O, where mBD =70° and mCA = 170°
m∠BPD: ____°.
mBC + mAD = ____°.
Answer:
m∠BPD: 120°
mBC + mAD =120°
Step-by-step explanation:
A figure which is formed by two rays or lines that shares a common endpoint is called an angle.
Given:
mBD =70°
mCA = 170°
So,
m∠BPD= 1/2( (m∠BD + m∠CA))
=1/2(170+70)
=1/2*240
=120
and,
mBC + mAD = 360 - ( 70 + 170 )
= 360 - 240
mBC + mAD = 120°

Show me how to find x using the correct equation shown here (geometry)
Answer:
x = 13
Step-by-step explanation:
The 2 angles same- side interior angles and sum to 180°
Then the equation to use to find x is
12x - 29 + 4x + 1 = 180
16x - 28 = 180 ( add 28 to both sides )
16x = 208 ( divide both sides by 16 )
x = 13
Answer:
13
Step-by-step explanation:
Angles ( 12x - 29 ) and ( 4x + 1 ) are co - interior angles.
Sum of co - interior angles are supplementary.
12x - 29 + 4x + 1 = 180
12x + 4x - 29 + 1 = 180
16x - 28 = 180
16x = 180 + 28
16x = 208
x = 208 / 16
x = 13

Rocco has a weekly reading schedule, reading for 4.5 hours per day on some days and 3.5 hours per day on the other days. He reads a total of 25.5 hours in a seven-day week. On how many days does he read for 4.5 hours?
Answer:
x = days he reads for 4.5 hours = 1 day
y = days he reads for 3.5 hours = 6 days
Step-by-step explanation:
Let
x = days he reads for 4.5 hours
y = days he reads for 3.5 hours
x + y = 7 (1)
4.5x + 3.5y = 25.5 (2)
From (1)
x = 7 - y
Substitute x = 7 - y into (2)
4.5x + 3.5y = 25.5 (2)
4.5(7 - y) + 3.5y = 25.5
31.5 - 4.5y + 3.5y = 25.5
- 4.5y + 3.5y = 25.5 - 31.5
-y = -6
y = 6
Substitute y = 6 into (1)
x + y = 7 (1)
x + 6 = 7
x = 7 - 6
x = 1
x = days he reads for 4.5 hours = 1 day
y = days he reads for 3.5 hours = 6 days

make y the subject please help
Step-by-step explanation:
Square both sides and you will get
3xy/(x + y) = 4
Multiplying both by (x + y), we get
3xy = 4(x + y) = 4x + 4y
Put all the terms containing y to the left side:
3xy - 4y = 4x
y(3x - 4) = 4x
or y = 4x/(3x - 4)
