Answer:
{16-10}{4+2}=36 For me, I use parenthesis () instead: (16-10)(4+2)=36
Step-by-step explanation:
With parenthesis, you don't have to put the multiply sign between the 2: (16-10) x (4+2) --> (16-10)(4+2).
Four students were asked to write an expression which has terms that have a greatest common factor of ab. The expressions provided by the students are shown below.
Michelle
16 a + 3 b
Naomi
18 a b c minus 13 a b c
Olivia
20 a b minus 14 a b c
Peyton
15 a b c + 14 a b
Which student wrote the correct expression?
Michelle
Naomi
Olivia
Peyton
Answer:
D.) Peyton
Step-by-step explanation:
If m is any integer, then gcd(a + m⋅b, b) = gcd(a, b). If m is a positive common divisor of a and b, then gcd(a/m, b/m) = gcd(a, b)/m. The GCD is a multiplicative function in the following sense: if a1 and a2 are relatively prime, then gcd(a1⋅a2, b) = gcd(a1, b)⋅gcd(a2, b). Factoring out the GCF is the first step in many factoring problems. Step 1: Determine the greatest common factor of the given terms. The greatest common factor or GCF is the largest factor that all terms have in common. Step 2: Factor out (or divide out) the greatest common factor from each term.
Answer:
peyton is correct because she is the only one with ab even in her awnser

It cost $5.25 for a bottle of 150 vitamins. if the cost varies directly with the number of vitamins in the bottle, what should a bottle of 250 vitamins cost?
what is the equation o the situation?
Could you please give me the equation and show me how you got it please so I could understand... thanks.
Answer: $8.75 for 250 vitamins.
Step-by-step explanation:
To find how much each vitamin costs we can divide $5.25 by 150.
5.25/150 = 0.035. So each vitamin is equal to $0.035.
We can then multiply the cost of 1 vitamin by 250.
0.035 x 250 = 8.75 or $8.75.
We can also make an equation for this problem. Let the total cost be equal to y and each vitamin equal to x.
y = 0.035x
So the equation above states that the total cost, y, is the amount of vitamins that are bought.
Use the quotient rule to simplify the expression. Write the expression with positive exponents.

Find the missing side length of the right triangle below.
26 cm
10 cm
b
Answer:
24
Step-by-step explanation:
we'll use the pythagoras theorm, but change it a little
instead of a² + b² = c², we'll use c² - a² = b²
26² - 10² = 576
the square root of 576 is 24, and that's the answer :)
Find the value of x
Answer:
it's 60
Step-by-step explanation:
Find the value of x.
Then find the value of y.
Answer:
x = 2°y = 150°Step-by-step explanation:
First, let's find x:-
(15x-2)° = (9x+10)°
15x-2 = 9x+10
6x = 12
x = 2°
Now, let's find y:-
28 + y° = 180°
y = 180-28
y = 150°

Tammy must run more than 67 miles total to reach her fitness goals. She has already run 35 miles and runs 4 miles per day, Which
of the following inequalities could be used to solve for x, the number of days Tammy still needs to run to reach her fitness goals?
Answer:
[tex]35 + 4x > 67[/tex]
To reach her fitness goal, she needs to run for more than 8 days.
Step-by-step explanation:
She has already run 35 miles and runs 4 miles per day:
This means that after x days, the distance she will have run is:
[tex]D(x) = 35 + 4x[/tex]
Tammy must run more than 67 miles total to reach her fitness goals.
This means that:
[tex]D(x) > 67[/tex]
[tex]35 + 4x > 67[/tex]
The inequality is:
[tex]35 + 4x > 67[/tex]
Solution:
[tex]4x > 32[/tex]
[tex]x > \frac{32}{4}[/tex]
[tex]x > 8[/tex]
To reach her fitness goal, she needs to run for more than 8 days.
