Answer:

$\bf\huge{8}$

Step-by-step explanation:

<h2>Given that:</h2>

20 divide ( 4 + 1) x 2

simplify

<h2>formulas used:</h2>

BODMAS

where,

B = bracket
O = of
D = division
M = multiplication
A = addition
S = subtraction

<h2>explanation:</h2>

⟼ 20 ÷ ( 4 + 1 ) × 2

⟼ 20 ÷ (5) × 2

⟼ 20 ÷ 5 × 2

⟼ 4 × 2

⟼ 8

∴ 20 ÷ ( 4 + 1 ) × 2 = 8.

<h2>Hence simplified ☑️</h2>

4+1= 5
20 divide 5 x 2
5 x 2 = 10
20 divided by 10 is 2

There was one half of a pizza left. It was divided equally amongst 3 kids. What fraction of the pizza did each kid get?

alukav5142 [94]

Answer:

one-sixth

multiply the numerator (2) by the number of kids (3) because you are accounting for the fraction of the whole pizza. By doing this you should get 3/6. divide the denominator by the number of kids (3/3) getting you to a value of 1, and replace the denominator, making the amount of pizza one-sixth.

The distance d of a particle moving in a straight line is given by d(t) = 2t3 + 5t – 2, where t is given in seconds and d is mea

Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

Given the distance, d(t) of a particle moving in a straight line at any time t is:

$d(t) = 2t^3 + 5t - 2, $ where t is given in seconds and d is measured in meters.$

To find an expression for the instantaneous velocity v(t) of the particle at any given point in time, we take the derivative of d(t).

$v(t)=\dfrac{d}{dt}\\\\v(t) =\dfrac{d}{dt}(2t^3 + 5t - 2) =3(2)t^{3-1}+5t^{1-1}\\\\v(t)=6t^2+5$

The correct option is C.

Answer:

dr. potter provides 54 vaccinations TOTAL (including both measles and polio).

p+m=54

since there are 4 doses of polio and of measles, you have to use a variable to distinguish how many doses were given for measles and polio out of 142 given doses.

4p+2m=142

p+m=54

4p+2m=142

^^system of equation

p+m=54

4p+2m=142

p=54-m

4p+2m=142

(substitute 54-m to the equation)

4(54-m)+2m=142

m=37

(collect like terms, then substitute the value of m into the first equation)

p=54-37

p=17

(m, p)=(37, 17)

Step-by-step explanation:

i hope this helps, sorry for the wait
