1 answer:

5 0

First, you have to divide 270 by 3, so you get 25%. This comes out to be 90. So, 90 is 25%. Now, multiply this by four to get 100%. This comes out to be 360. So, 270 is 75% of 360, which answers the question '270 is 75% of what number?'

PLS HELP ME,I'LL MARK U AS BRAINLIEST IF U HELP ME!!!! 1. Write the algebraic expressions of the following. a) Twice of a number

harina [27]

Step-by-step explanation:

Twice of a number added to 5.

Let the number be n.

Twice of the number: 2n

Twice of the number added to 5: $2n+5$

Difference of squares of m and n multiplied by 6.

Difference of squares: $m^{2} -n^{2}$

Difference of squares multiplied by 6: $6(m^{2} -n^{2} )$

r cubed minus y squared

r cubed: $r^{3}$

y squared: $y^{2}$

r cubed minus y squared: $r^{3} -y^{2}$

Five times of x raised to the power of 5 added to twice of y cubed

Five times of x raised to the power of 5: $5x^{5}$

Twice of y cubed: $2y^{3}$

Five times of x raised to the power of 5 added to twice of y cubed:

$5x^{5} +2y^{3}$

6r+7=13+7r I don’t know what it is

Sergio [31]

6r+7=13+7r

Move 7r to the other side. Sign changes from +7r to -7r.

6r-7r+7=13+7r-7r

6r-7r+7=13

-r+7=13

Move +r to the other side. Sign changes from +7 to -7.

-r+7-7=13-7

-r=6

Multiply by -1 to get positive and for 6

-r(-1)=6(-1)

r=-6

Answer: r=-6
