Answer:
12 years old
Step-by-step explanation:
let h = helmi's age and let s = son's age (right now)
10s = 3h
h + 5 + s + 5 = 62
h + s + 10 = 62
h + s = 52
3h + 3s = 156
10s + 3s = 156 (substitution)
13s = 156
s = 12

Find the Least Common Denominator. Then, express each fraction using the Least Common Denominator.
7/10 and 5/6
Answer:
LCM of 7/10- 70
LCM of 5/6- 30
Step-by-step explanation:
Solution:
To find the Least common denominator (LCD) of 7/10 and 5/6, we need to find the Least common multiple of 10 and 6.
I found the LCM through division method. Refer to image attached~
We can tell that:
The LCM is 2 x 3 x 5, which when simplified, we obtain 30. The LCD is 30.Now, let's multiply the denominators and the numerators such that 30 is the denominator in both fractions.
=> 7/10 = 7 x 3/10 x 3 = 21/30=> 5/6 = 5 x 5/6 x 5 = 25/30The fractions are:

heather ate 3/6 of a box of cookies. Melody ate 3/5, who ate
more?
Answer:
Melody
Step-by-step explanation:
3/6 = 0.5
3/5 = 0.6
i.e. If it has the same numerator but different denominator the one with the smaller denominator will be bigger
Answer: Melody ate more.
Step-by-step explanation:
So, it would be Melody who ate more because
Over here:
Heather: ate 3 OUT of 6
Melody: ate 3 OUT of 5
Melody ate more because if you count up to 5 theres two cookies left, while Heather had 3 cookies left.

Answer: $180,495 is the take-home after the broker's commission.
Step-by-step explanation:
calculate the measure of each angle. find X
Solution:
Note that:
4x - 27 = 3x + 4 (Vertically opposite angles)Using the equation (4x - 27 = 3x + 4), solve for x.
4x - 27 = 3x + 4=> -3x + 4x - 27 = 3x + 4 - 3x=> x - 27 = 4=> x - 27 + 27 = 4 + 27=> x = 31The measure of x is 31.
Solve for X ~
[tex] \bf4x - 27 = 3x + 4[/tex]
[tex] \bf \: 4x - 3x = 4 + 27[/tex]
[tex] \boxed{ \bf \: x = 31}[/tex]
Now, Finding each angle⤵️[tex] \tt \: ∠1 = 2x + 21 \\ \tt \: = 2 \times 31 + 21 \\ \tt \: ∠1= 83 \degree[/tex]
[tex] \tt \: ∠2 = 4x + 27\\ \tt \: = 4\times 31 - 27 \\ \tt \: ∠2= 97 \degree[/tex]
[tex] \tt \: ∠3 = 3x + 4 \\ \tt \: = 3\times 31 + 4 \\ \tt \: ∠3= 97 \degree[/tex]

Jen traveled from Boston to Cape Cod at 60 mph. On her way back, the
traffic was bad and her return trip took 3 times as long. What was Jen's
average speed on the round trip?
Jen's average speed on the round trip will be 20mph
Distance and spedThe formula for calculating speed is expressed as:
Speed = Distance/Time
d = st
Let the time taken on Jen's way to Cape Cod be "t"
The time taken back to Boston will be t + 3
d1 = 60t
d2 = 60(t+3)
Since he traveled the same distance to and fro, hence;
Average speed = 60/3
Average speed = 20mph
Hence Jen's average speed on the round trip will be 20mph

Answer:
a) 1.2 seconds
b) 50 bpm
Step-by-step explanation:
a)The period is the value of t that makes the angle be 2π:
5πt/3 = 2π
t = 3(2π)/(5π) = 6/5
The period of the function is 6/5 = 1.2 seconds.

b)The number of beats per minute is ...
(1 beat)/(1.2 s) × (60 s)/(1 min) = 60/1.2 beats/min = 50 beats/min
How many gallons of 35% alcohol solution and 50% alcohol solution must be mixed to get 9 gallons of 40%
alcohol solution?
There needs to be____
gallons of 35 % alcohol solution and____
gallons of 50 % solution.
There needs to be 6 gallons of 35 % alcohol solution
and 3 gallons of 50 % solution.
======================================================
Explanation:
x = number of gallons of the 35% solution
y = number of gallons of the 50% solution
The two amounts must add to 9 gallons, so x+y = 9
This solves to y = 9-x
Since we want 9 gallons of 40% alcohol solution, this means we want 0.40*9 = 3.6 gallons of pure alcohol.
----------------
0.35x = amount of pure alcohol from the first batch
0.50y = amount of pure alcohol from the second batch
0.35x+0.50y = total amount of pure alcohol
Set that expression equal to the 3.6 figure calculated earlier (the total amount of pure alcohol we're after) and we get this equation
0.35x+0.50y = 3.6
----------------
Next, we replace y with 9-x and then solve for x.
0.35x+0.50y = 3.6
0.35x+0.50(9-x) = 3.6
0.35x+4.5-0.50x = 3.6
-0.15x+4.5 = 3.6
-0.15x = 3.6-4.5
-0.15x = -0.9
x = -0.9/(-0.15)
x = 6
We'll need 6 gallons of the 35% solution
Use this x value to find y
y = 9-x
y = 9-6
y = 3
We'll also need 3 gallons of the 50% solution

Write the trinomial as a square of a binomial or as an expression opposite to a square of a binomial: -1 + 4a -4a^2
Answer:
-(1 - 2a)^2
Step-by-step explanation:
-1 + 4a - 4a^2
= -[1^2 - 2*1*(2a) + (2a)^2]
= -(1 - 2a)^2
Answer:
Step-by-step explanation:
Begin by taking out the minus
-(4a^2 - 4a + 1) The answer is the square root of the 1st and 3rd terms.
√4a^2 = 2a
√1 = 1 Since middle term is minus, one of 2a or 1 must also be minus
Usually the one is made minus.
That leaves you with a perfect square
- (2a - 1)^2 There are more ways than 1 to write this, but I think this is the clearest answer
