Matt is four years younger than twice his cousin Andy’s age. The sum of their ages is greater than 35. What is the youngest age that Andy can be?
Answer: 13
Step-by-step explanation:
let m = Matt's age
let a = Andy's
:
Write an equation for each statement
:
Matt is four years younger than twice his cousin Andy’s age.
m = 2a - 4
The sum of their ages is greater than 35.
m + a > 35
What is the youngest age that Andy can be?
replace m with (2a-4) from the 1st statement
2a - 4 + a > 35
3a > 35 + 4
a > 39/3
a > 13
least integer has to be a = 14
:
:
Check, find m
m = 2(14) - 4
m = 24
24 + 14 = 38 greater than 35
If a = 13
m = 2(13) - 4
m = 22
22 + 13 = 35 which is not greater than 35

Answer:
Step-by-step explanation:
(x + 6)/2 = -3
x + 6 = -6
x = -12
(y - 2)/2 = 0
y - 2 = 0

Desmond builds a set of towers out of blocks. The table shows the number of blocks in each tower. Tower # 1 2 2 3 4 5 Number of blocks 5 10 20 40 80 Which explicit formula correctly represents the number of blocks, an, in terms of the tower number, n? A. an = n + 80 B. an = 2n + 5 C. An = 5(2)n-1 D. an = 10(5)
Answer:
C. An = 5(2)^n-1
Step-by-step explanation:
Tower 1 2 3 4 5
Number of blocks 5 10 20 40 80
Where,
n = tower number
An = number of blocks
A. an = n + 80
B. an = 2n + 5
C. An = 5(2)^n-1
D. an = 10(5)^n
Checking all options
A. An = n + 80
When n = 1
An = 1 + 80
= 81
B. An = 2n + 5
When n = 1
= 2(1) + 5
= 2 + 5
= 7
C. An = 5(2)^n-1
When n = 1
= 5(2)^1-1
= 5(2)^0
2^0 = 1
= 5(1)
= 5
D. An = 10(5)^n
When n = 1
= 10(5)^1
5^1 = 5
= 10(5)
= 50
The explicit formula which correctly represents the number of blocks, an, in terms of the tower number, n is C. An = 5(2)^n-1

C

Step-by-step explanation
Math equations that equal 31
Use the figure below to find the value of y and each angle shown.
5y - 16 + 3y + 20 = 180 degrees
Combine like terms on the left side
8y + 4 = 180
Subtract 4 from both sides.
8y = 176
Divide both sides by 8
y = 22
Plug 22 into y for each angle.
3y + 20 = 3(22) + 20 = 66 + 20 = 86 degrees
5y - 16 = 5(22) - 16 = 110 - 16 = 94
The angle opposite 5y - 16 also equals 94 because they are vertical angles.
The angle opposite of 3y + 20 also equals 86 because they are vertical angles

I used the formula (32°F − 32) × 5/9 = 0°C (but ofc replaced the numbers with 99)
Yeah and i rounded 98.6 to 99. 99 Fahrenheit is 37.2222... so i rounded it down to 37. So i think the answer is 37.
