Subtract 7x+27x+2 from -5x^2-2x−5x 2 −2x.
kicyunya [14]

Simplified value of  subtraction of 7x+27x+2 from -5x^2-2x−5x 2 −2x. is -10x^{2} -38x-2.

Given Expressions  7x+27x+2 and  -5x^2-2x−5x 2 −2x.

Expressions refers to the combination of numbers, variables and symbols. It represents the relationship between variables. They are solved for finding out the value of variables. It is mainly not in equal to form. Subtraction is possible when subtracting the coefficients of same variable.

We have to subtract 7x+27x+2 from -5x^2-2x−5x 2 −2x. and to do this we need to first solve the expressions itself.

7x+27x+2=34x+2------------------1

-5x^{2} -2x-5x^{2} -2x=-10x^{2} -7x-2x--------------------2

Now subtract 1 from 2

=-10x^{2} -7x-2x-34x+2

=-10x^{2} -38x-2.

Hence the simplified value of subtraction is -10x^{2} -38x-2.

At a swim meet 20 medals were a warded. Four were gold metals 45% of the metals were silver the rest were bronze. What percent o
Eddi Din [679]

Answer:

35%

Step-by-step explanation:

To figure out the percentage of bronze medals, we must figure out the percentages of the gold and silver medals first.

We already know that 45% of the medals were silver.

We know that 4 of the 20 medals were gold.

4/20 as a percentage would be 20/100, or 20%.

So, 20% of the medals were gold, and 45% of them were silver.

45% + 20% = 65%

100% - 65% = 35%

So, 35% of the medals awarded were bronze.
